Reddit and its partners use cookies and similar technologies to provide you with a better experience. Given many of you won't have seen this metric before, I'll provide some context, in that scoring 414 points here is excellent and indicates a fast panel. All things considered this isn't the worst result I've seen from a wide gamut display, and some people actually like this look, but it could be better. Samsung's latest VA technology with no dark level smearing is extremely impressive, and holds up a bit better for these premium high refresh rate displays than IPS. www.dell.com. Comparing the AW2721D to other gaming monitors, the response time numbers are generally very solid when looking at peak performance recorded at the display's maximum refresh rate. Musk to lay off half of all Twitter employees, and then some, AMD set to unveil Radeon RX 7000 GPUs later today. Input lag is virtually zero, and the build quality was impressive and befitting of its price tag. Apache JMeter and TechSpot is supported by its audience. It really depends on your application and the audience that will be using it. Excellent but reasonably priced 240Hz gaming monitor. It is HDR compatible and features 98% DCI-P3 coverage, so we'll see how it performs a bit later. Using our newer test methodology which is gamma corrected and measures more of the response time curve, we do spot some slower transitions, particularly fall times that have a longer trail. What have your experiences been? The majority of transitions are not affected by any sort of noticeable overshoot, and instead we are left with a 4.47ms grey to grey average response time, which is excellent. This is the first monitor we're reviewing using our updated test methodology for 2021. Not having an sRGB emulation mode in such a high-end product is a noteworthy omission. The more detailed the information to be remembered, the greater the need for responses of less than 2 seconds. A delay longer than 2 seconds can be inhibiting to operations that demand a high level of concentration. We are going to look in this post at how we might categorise response times based on the interaction model with the end-user. New comments cannot be posted and votes cannot be cast. The overdrive settings above Fast are not worth using. Seems like it could also be the NanoIPS panel. They provide a way, if needed, of prioritising your testing focus by prioritising the business transactions with the more aggressive response times. Screen Size: 24.5 inches. In terms of the best performance at 240Hz, the AW2721D isn't quite as good as the Odyssey, mostly due to higher overshoot at a similar response time average. A delay longer than 2 seconds can be inhibiting to operations that demand a high level of concentration. Many computer games require extremely fast interaction. This will leave viewers with an oversaturated experience in many instances, especially when (for example) watching YouTube videos, something that does not play nicely with ICC profiles. 2 to 4 seconds. Certain types of thought-intensive work (such as writing a book), especially with applications rich in graphics, require very short response times to maintain end users' interest and attention for long periods of time. RGB lighting is found here, integrated into a light bar on the back of the stand as well as the classic alien head logo. But these displays do trade blows and . Alienware AW2721D - Super Fast, Extreme - 240Hz. If the Acer has a good variable overdrive implementation and bests the AW2721D in response time charts then I will definitely switch. I put my brightness down to 10% and it still felt really bright. Wrapping up our performance testing is a look at HDR. High-end ultrawides may also come into consideration although at that point we're basically talking about a different monitor category. Previous Nano IPS panels already had the response times to handle a 240Hz refresh rate, they just needed that sort of refresh rate to be unlocked, and it seems like that's basically what we are getting here. Thus, for complex activities, such as browsing products that vary along multiple dimensions, 2 seconds represents an important response-time limit. The central zone was great but my unit did exhibit some IPS glow in the bottom right corners, although your mileage may vary and I suspect this will improve on my sample over time. I'd have much rather Alienware include a mode below "Fast" with less overshoot, than bother with this "Extreme" mode that looks a lot worse. There is no set generic industry standard for performance response times and there is very little been written about the subject. The Acer also seems to have faster response times based on Bijan Jamshidi's reviews. Alienware only offers three response time settings, however the monitor uses a native G-Sync module, so variable overdrive is a feature and thus we shouldn't have to change settings very often. However fundamentally this new 1440p 240Hz IPS panel from LG does not push IPS ahead in terms of response behavior compared to what was already on the market. In terms of performance across the refresh range, buyers of the AW2721D should stick with using the Fast mode, which provides a single overdrive mode experience, exactly what I'd expect from a premium display. With this in mind services interaction would fall in the sub-second response time category. The AW2721D does deliver great performance in that 5ms range, but it's not fundamentally different to other offerings, so buyers of this display should be primarily interested in gaming above 165Hz either now or in the future. The Alienware AW2721D is a great high-end gaming monitor and one that shows the promise of IPS technology for 1440p 240Hz applications. JMeter are trademarks of the Apache Software Foundation (ASF). A response to pressing a key (e.g., seeing the character displayed on the screen) or to clicking a screen object with a mouse must be almost instantaneous: less than 0.1 second after the action. If a panel cannot improve upon its SDR numbers in this test, it's not delivering a true HDR experience. I am down to 2% now (75% contrast) trying to see if that helps reduce the eye strain I am getting. Your post has failed. Alienware AW2721D - D65-P3, tested at native resolution, highest refresh rate The good news though, is it is actually available, which we can't say about every new bit of hardware we test these days. If you missed all that detail, it's well worth a watch. For some reason, RGB balance also gets a lot colder at higher brightness levels, while it's decent and quite accurate at lower brightness levels. Based upon analysis carried out from a productivity perspective we can see that this is still relevant. There's also no backlight strobing available, as the LG IPS panel has a slow red phosphor, which interferes with strobing as we've seen previously. and our Thanks to advancements made in the last few years, IPS is definitely fast enough for these sorts of refresh rates, and while this particular monitor doesn't set any new performance records, it was consistently near the top of our response time charts which is what buyers forking out over $800 on a new monitor will be after. And you'll see what I'm talking about when we look at response times recorded at 120Hz. However when measuring within a single frame, the AW2721D in even the best case scenario fails to reach a baseline target contrast ratio of 50,000:1 for an okay HDR experience. The next step is a full calibration and as expected I achieved excellent results. G-Sync Ultimate used to be for the best HDR displays on the market, but that's not the case in 2021, as the AW2721D has somehow qualified despite having just DisplayHDR 600 certification and only edge-lit local dimming. With LG IPS panels there is always some discussion on contrast ratio, especially since the early days of monitors like the 27GL850. Batch response times need consideration as well which is something that is missing from here. Average performance across the refresh range is also very solid, and interestingly performance is very similar between the AW2721D and Dell S2721DGF, both of which use LG IPS panels. Maximum brightness is outstanding in the SDR mode, pushing 532 nits which is more than sufficient for indoor usage in pretty much all environments. When the application user has to remember information throughout several responses, the response time must be short. The Extreme mode is even worse, and to me this looks like a setting included purely to market the monitor as being "1ms" - you can see the best transitions are in the 1ms range. An artist dragging an image to another location must be able to act instantly on his next creative thought. As for whether you should buy the AW2721D, I'm sure a lot of people are wondering whether to get this, or go for something like the Samsung Odyssey G7, so here's my simple breakdown as I've tested both. We're kicking things off today with our first monitor review of 2021, we're taking a look at the Alienware AW2721D, a hot item at the moment. Privacy Policy. Such delays would inhibit problem-solving activity and frustrate data entry. While the AW2721D doesn't have a fantastic contrast ratio, easily beaten by VA panels, I recorded roughly a 1000:1 result which is on par for a modern IPS monitor. OctoPerf 2014 - 2022. When this analysis was taking place the concept of service-based architecture and cloud computing was not something that would have been considered. However the Odyssey G7 is only a gaming display. It is a lot harder to agree on what the response times of your application should be. Unfortunately when viewing sRGB content there is going to be some level of oversaturation. As grayscale performance is great from the factory and there's no sRGB mode, there is little that can be done in the OSD to improve performance, aside from a few minor tweaks if things are slightly off. Super Fast does decrease response times to 3.57ms on average, but this comes with a significant increase to overshoot. The AW2721D is a large monitor for something that only has a 27-inch panel, and I'm not talking about bezels but the overall monitor body. This Alienware monitor does benefit from an increased refresh range, and does so without negatively affecting its overall performance. However, after the completion of a transaction, delays of 4 to 15 seconds can be tolerated. On average across the refresh range, the G7 does have a clearer edge, ending up with less overshoot and also a 10 percent faster response on average. But these displays do trade blows and the Alienware monitor isn't that far behind. Your comment has been submitted and will be published once it has been approved. But for today's gaming, I'd swing more towards the AW2721D especially as the 27GN950 lacks HDMI 2.1. Cookie Notice It also has native G-SYNC support and is compatible with FreeSync to reduce screen tearing. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. If you're after just a pure gaming monitor, the Odyssey G7 is probably going to be the better option. But this isn't significant enough to affect overall performance and I'd say that with calibration the AW2721D is a great monitor for P3. Of the three pillars of HDR, what this monitor lacks is proper local dimming; we're getting only 32 edge lit zones, which is insufficient for producing bright highlights and deep blacks on screen at the same time, a cornerstone of an HDR presentation. How can we ensure there is a measure to test against? It has a 240Hz refresh rate, a 1ms response time, and supports FreeSync and G-Sync modesand it's . We need to be able to answer these questions: At what point does a response time become unacceptable? Resolution: 1920 x 1080. Having a standard set of response time requirements is not the right idea, having boundaries that you can work in is a more sensible. The color controls are a little lacking, however for gamers you do get refresh rate and timer options, though no cheat crosshairs. When comparing factory greyscale calibration to other monitors I've tested, the Alienware AW2721D is one of the best, topping the charts as I like to see from premium displays. I'm not a fan of the large 27 printed onto the rear but outside of that it's a pretty clean body with some nice curves. Anything below 5ms is excellent and delivers a highly responsive experience. The Alienware AW2521HFL is one of the best 24.5-inch monitors you can buy. After all, hitting 1440p at 240 FPS in today's games is quite a challenge. These delays are generally too long for a conversation, requiring the end user to retain information in short-term memory (the end users memory, not the computers!). Variable overdrive keeps performance solid across the refresh range, leading to a coveted single overdrive mode experience. In a best case scenario, the AW2721D can change from dark to bright in separate frames to good effect, delivering a dynamic contrast ratio as high as 63,000:1. This is with a bright and dark object far away on the screen. Apache, It helps define it based on so real analysis rather than assumption of guess work. Categorising your business functionality or user journeys this way helps with requirement creation. The Dell Alienware AW2721D is an impressive 1440p gaming monitor. And in our worst case single frame contrast test, which measures a bright and dark object side by side, the AW2721D does not deliver an HDR experience. Lets look at the findings and we will discuss further in the next section. However, a big negative is the AW2721D does not have an sRGB mode, so there is no way to emulate or clamp this gamut down to sRGB for viewing regular content. Again the main benefit is simply a higher refresh rate overall. Alienware AW2521HFL. I'm not sure how many people actually would want to do that, but as you can see there is some overshoot present on the lowest mode, and without a lower setting this is the least amount of overshoot you'll see. Portrait CALMAN Ultimate, DeltaE Value Target: Below 2.0, CCT Target: 6500K. As a result, our cumulative deviation numbers increase, suggesting we are further from an ideal response than in the previous mode. Again, a delay in this range may be acceptable after a minor closure. If you enjoy our content, please consider subscribing. At times, overshoot can be a little higher than I'd like, in particular at 200Hz, but for the most part the level of overshoot is manageable and not that noticeable in practice. The level of height adjustment is also generous and I think it's helped by having such a huge stand assembly - even though the stand legs don't take up a ton of desk space. TECHSPOT : Tech Enthusiasts, Power Users, Gamers, TechSpot is a registered trademark. An average result below 5ms is elite, putting this display among the fastest I've tested. A greyscale deltaE ITP below 2.0, and strong performance in other color metrics when measuring against sRGB; no surprise as there is 100% coverage of this color space. The analysis above would then seem to be a great starting point for defining your non-functional response time requirements. Alienware are touting "true 1ms GTG response time" - we'll see about that - but we do know the monitor uses a latest-generation LG IPS panel so we're expecting performance that's similar to other LG IPS products. We also get 70% refresh compliance, which using our new methodology is sufficient to call this a true 240Hz display, which is a great sign from an IPS panel. I was quite impressed with this display's versatility. Without this critical measure we really cannot say for certain that an application or service performs. There's very little color shift when viewing at off angles which gives you the flexibility to view this display in different ways. Response times are difficult to define and even harder to get agreement on with the end-users. Using a category-based system is useful and scientific enough for the business and development teams to agree on. Cyrix 5x86 and Cyrix 6x86: Gone But Not Forgotten, Nvidia DLSS 2 vs Intel XeSS vs AMD FSR 2 on Nvidia GeForce and AMD Radeon GPUs, Galax RTX 4090 HOF comes with two 12VHPWR connectors and 1,000W power limit, overclocked to over 3.7 GHz. You can see variable overdrive at play here, especially below 100Hz, where the monitor appears to switch to a slower mode to keep overshoot in check. One thing that G-Sync Ultimate monitors tend to succeed at is factory greyscale calibration and that's no exception with this display. At this price, there are a couple of other options, like going 4K 144Hz with a monitor like the LG 27GN950. Sustained brightness of around 520 nits with a full white window is decent, and that increases to 750 nits for bright flashes, enough to dazzle in indoor conditions. The reason being that we are not measuring the response time under load against a value that has been agreed upfront. The display can also sustain over 700 nits for lower window sizes, adding to a decent but not chart topping collection of brightness numbers. Not at all. The use of an LG IPS panel prevents us from getting backlight strobing for added motion clarity. Is this level of overshoot problematic? Join thousands of tech enthusiasts and participate. I was also generally pleased with uniformity, although there was some fall off along the outer edges. My unit had near perfect adherence to the sRGB gamma curve, and a negligible deviation from the accurate CCT curve. This monitor doesn't handle brightness roll off well, so elements that should be bright are not as bright as they should be. OctoPerf integrates with your servers / CI / APM. Thank You! It may be acceptable to make purchasers wait 2 to 4 seconds after typing in their address and credit card number, but not at an earlier stage when they may be comparing various product features. A wait of 2 to 4 seconds can seem surprisingly long when the end user is absorbed and emotionally committed to completing the task at hand. Using the same principles you can categorise your batch response times based on how long your batch window is verses how may batches need to be run. However since that initial release of Nano IPS displays, LG has been able to improve the contrast ratio with newer panels. And while the majority of the outer materials are plastic, I think it looks quite premium with its mixture of black and white soft finishes. You can also look to include their relative importance and complexity into your thinking. Please return to the page and try again. What the AW2721D gets right is brightness. VISIT SITE. Viewing angles are outstanding, and LG panels remain some of the best on the market in this area. It looks at how productive the end users could be based on the speed of the technology platform they we using.While the research is old it provides a useful set of conclusions that to a degree are still relevant today. There are several other little bonuses sprinkled in here as well. Has anyone calibrated the monitor yet? The overshoot numbers are not amazing compared to the Omen X 27 for example, however performance is a step above 144 and 165Hz displays of the past, like the LG 27GL850. Similar results in ColorChecker, the positive being that skin tones aren't affected significantly so it's unlikely you'll see a "sunburned" look, however oversaturation is still present. performance testing , response times , response thresholds , non-functional requirements , end-user productivity , cloud computing , web services , industry standard , batch processing , application complexity , end-user requirements, https://octoperf.com/blog/2022/10/31/performance-response-times/, ZI Les Paluds, 276 Avenue du Douard, 13400 Aubagne, France, Performance Testing for Large Scale Programmes, Apache JMeter and A threshold of 2 seconds was the recommendation for applications that interact with users. But he did not to pixel response testing, so I would like to see a review from tftcentral, rtings, or hardware unboxed. The on screen display is controllable through a directional toggle placed behind the monitor's bottom right corner, where you'll find a modest set of features. Meanwhile, due the way variable overdrive operates on this monitor, the AW2721D is only a mid-range performer at 60Hz. The analysis above would seem to indicate that the 15 second category is the one that asynchronous transactions fall into. Alienware are offering the full complement of adjustability, including height, tilt, swivel and pivot capabilities, so you could operate this monitor in a portrait orientation if you wanted to. We may earn a commission when you buy through links on our site. ColorChecker factory calibration is also not the worst, although sRGB only monitors like the BenQ EX2510 do deliver a noticeably better experience. So let's see how it performs At 240Hz using the lowest overdrive mode, Fast, it's clear that overdrive is indeed enabled. For more information, please see our The Alienware AW2721D is a new high-end 27-inch 1440p monitor, giving us our first look at the combination of a 240Hz refresh rate and IPS technology at this resolution. When viewing cumulative deviation, showing how close the monitor gets to the ideal response, the AW2721D sits among a huge glut of modern IPS monitors that all deliver a similar experience, in that 500 to 600 point range when measured across their refresh range. The AW2721D, despite being G-Sync Ultimate, is only a semi-HDR panel. All of these elements combined with response time numbers that aren't too far off the Odyssey, means it's a great balance of features. That's not a bad thing at all, but those wanting an AW2721D specifically for better performance even at lower refreshes like 144Hz aren't really getting that. Despite such high peak brightness, the AW2721D also delivers great minimum brightness at a touch below 50 nits, so there is a large range of values to tweak brightness to your liking. It has a 240Hz maximum refresh rate, an exceptional response time that results in minimal motion blur, and an incredibly low input lag that makes gaming feel responsive. Another important point on the spec sheet is G-Sync Ultimate support, although it's the new watered down G-Sync Ultimate, not the high standard the program once commanded. An average result is around 600. With features like 96% P3 coverage, excellent factory greyscale calibration, and a nice flat panel with excellent viewing angles, the AW2721D is suitable for creative and general office work, too. And despite being a G-Sync Ultimate display, the HDR performance on offer is poor due as we're only getting edge lit local dimming. This led to low deltaEs from the factory, and virtually no appreciable tint to the monitor. Nothing unusual from the power consumption side of things, the AW2721D is slightly more efficient than the HP Omen X 27's TN display, even factoring in RGB lighting. Input latency is excellent at 240Hz, with practically no processing delay on the monitor's side, leaving the only remaining latency due to refresh lag and response lag. The following summarises research conducted in the late 1980s that attempted to map end-user productivity to response times. JMeter. It is relatively easy to predict volumes, load and users that will use your application as you will no doubt have some data based on your current systems. This rules out conversational interaction. This is fine for lower refresh rate gaming and I'm glad it's implemented this way to prevent users from having to change overdrive settings depending on the refresh rate they are gaming at. For certain types of applications, certain types of end users may be content to sit at a terminal for more than 15 seconds waiting for the answer to a single simple inquiry. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. In terms of HDR accuracy, the display is also a mixed bag. A wait of 2 to 4 seconds can seem surprisingly long when the end user is absorbed and emotionally committed to completing the task at hand. 2022 TechSpot, Inc. All Rights Reserved. On the positive side, the AW2721D does feature excellent factory greyscale calibration. Was wondering what fellow owners were using for their brightness/contrast settings. About Us Ethics Statement Terms of Use Privacy Policy Change Ad Consent Advertise. If you want a single monitor in your setup to tackle both high-end gaming and productivity, then something like the AW2721D is going to set you up perfectly now and for many years into the future. It's cheaper, especially at 27", and features better response time results. Clearly, as we have already stated, each organisation and application is different. And use these metrics to build response time requirements as part of your wider non-functional requirements. Alienware AW2721D - Fast - 240Hz, 200Hz, 165Hz, 144Hz, 120Hz, 100Hz, 85Hz, 60Hz. You'll need to use DisplayPort to access the maximum 240Hz refresh rate, as HDMI is limited to just 144Hz at this resolution, and this display does not support HDMI 2.1. You're actually better off with an LG 27GL850 for gaming in that lower refresh range, although if you wanted faster response times and were okay with much higher overshoot then you could increase the overdrive mode one notch. If such delays could occur, the system should be designed so that the end user can turn to other activities and request the response at some later time. Particularly when viewing P3 and Rec.709 sweeps inside BT.2020, the results were better than I expected, so saturation tends to be quite well held in this mode and this should deliver a good color experience. Tucked neatly behind the magnetic port cover are a DisplayPort and two HDMI ports, plus some USB ports. When defining these you should do so with your end users or business teams. Moving into color performance and the AW2721D is a wide gamut display, featuring 96% coverage of the P3 color space, so that's great for creators that want to leverage this display for their wide gamut work. In practice there is significant haloing, extending from the edges of the monitor to any bright objects, and this can be distracting and worse than no local dimming at all depending on the content. The AW2721D offers something a bit different, and it's also more expensive, currently $825 when bought directly from Dell or Amazon. It also has the benefit of twice the contrast ratio, and includes backlight strobing which is a feature that many people desire for its motion clarity benefits. The stand is beefy and it attaches to a rather thick display housing; the whole thing is much heavier than I expected, although this allows it to be very sturdy. You need to be a member to leave a comment. In terms of the best performance at 240Hz, the AW2721D isn't quite as good as the Odyssey, mostly due to higher overshoot at a similar response time average. When performance testing you need a set of requirements to measure your response times against. A couple of weaknesses shown in red but on the whole, a lot of green results indicating this monitor performs above average compared to all the other displays we've tested so far. RDNA 3 incoming: Watch AMD unveil Radeon RX 7000 graphics cards here at 1pm PT / 4pm ET, Elon Musk set to lay off half of all Twitter employees, end work-anywhere policy, Call of Duty: Modern Warfare II's opening weekend was the best in franchise history, October survey puts Windows 11 adoption at just 15 percent worldwide, Meta's AI-assisted audio codec claims 10x compression rate compared to MP3s, Samsung Odyssey G9 49" Super-Ultrawide on, Ad-free TechSpot experience while supporting our work. The reason I make this rather obvious point is that as Fast is the "lowest" mode, you actually can't disable overdrive on this display entirely. The AW2721D with its IPS panel is much more versatile and I'd recommend it for those that also want to use their monitor for other things. My old monitor was the Asus PG279QZ. This isn't a huge selling point for me, but it is something that other people find useful. With its 1440p 240Hz capabilities, this new Alienware display is competing directly with the Samsung Odyssey G7, another 1440p 240Hz display we've looked at with a curved VA panel instead. You can see how it stacks up here in our performance summary chart, new for this review and something we might use going forward. All rights reserved. However in the HDR mode, the AW2721D doesn't do the worst job of keeping to proper saturation performance within the limits of what the display can do. For P3 work we see generally strong results, although as coverage is only 96% instead of 100%, you will lose a small amount of accuracy at the top end of the saturation range. On the right you'll see our new cumulative deviation results, which measure how close the response behaviour gets to the ideal "instant" response. Price: $249.99. Again, a delay in this range may be acceptable after a minor closure. How can response times be defined in the requirements gathering stage? This is because edge lit local dimming can not sufficiently dim the screen for HDR content, so within each column zone you fall back to the display's native contrast ratio. However, to the busy call-centre operator or futures trader, delays of more than 15 seconds may seem intolerable. While on the whole this is a great display and I'm very positive about the results, there are some oversights. We would also need to consider asynchronous transactions where the application is processing after a response has been received. However based on the displays I've tested so far, this is somewhat common for IPS panels and this is far from the worst example. This would still seem a sensible and again might be a response time to use as your requirements for all user-based interactions. The Alienware's flat panel is also much better at this size, plus you're getting better viewing angles, better uniformity, a wider color gamut and better factory calibration. Testing is a great high-end gaming monitor and one that shows the promise of IPS technology for 1440p 240Hz..
