An average result below 5ms is elite, putting this display among the fastest I've tested. 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. 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. If a panel cannot improve upon its SDR numbers in this test, it's not delivering a true HDR experience. We may earn a commission when you buy through links on our site. 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. Without this critical measure we really cannot say for certain that an application or service performs. You can also look to include their relative importance and complexity into your thinking. The AW2721D, despite being G-Sync Ultimate, is only a semi-HDR panel. At this price, there are a couple of other options, like going 4K 144Hz with a monitor like the LG 27GN950. The AW2721D offers something a bit different, and it's also more expensive, currently $825 when bought directly from Dell or Amazon. This rules out conversational interaction. 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. 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. 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. Again, a delay in this range may be acceptable after a minor closure. 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. All rights reserved. This isn't a huge selling point for me, but it is something that other people find useful. 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. Having a standard set of response time requirements is not the right idea, having boundaries that you can work in is a more sensible. 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. If you're after just a pure gaming monitor, the Odyssey G7 is probably going to be the better option. Alienware AW2521HFL. Price: $249.99. A delay longer than 2 seconds can be inhibiting to operations that demand a high level of concentration. Not having an sRGB emulation mode in such a high-end product is a noteworthy omission. 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. 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!). When defining these you should do so with your end users or business teams. Batch response times need consideration as well which is something that is missing from here. For more information, please see our We would also need to consider asynchronous transactions where the application is processing after a response has been received. 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. In terms of HDR accuracy, the display is also a mixed bag. Your post has failed. Not at all. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The color controls are a little lacking, however for gamers you do get refresh rate and timer options, though no cheat crosshairs. 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 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. 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. When the application user has to remember information throughout several responses, the response time must be short. 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. There's very little color shift when viewing at off angles which gives you the flexibility to view this display in different ways. 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. 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. This is the first monitor we're reviewing using our updated test methodology for 2021. Apache, 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. 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. 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. 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. As a result, our cumulative deviation numbers increase, suggesting we are further from an ideal response than in the previous mode. On the right you'll see our new cumulative deviation results, which measure how close the response behaviour gets to the ideal "instant" response. It has a 240Hz refresh rate, a 1ms response time, and supports FreeSync and G-Sync modesand it's . We are going to look in this post at how we might categorise response times based on the interaction model with the end-user.

But these displays do trade blows and the Alienware monitor isn't that far behind. Please return to the page and try again. 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. Alienware AW2721D - Fast - 240Hz, 200Hz, 165Hz, 144Hz, 120Hz, 100Hz, 85Hz, 60Hz. It helps define it based on so real analysis rather than assumption of guess work. 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. Cookie Notice 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. 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. After all, hitting 1440p at 240 FPS in today's games is quite a challenge. I put my brightness down to 10% and it still felt really bright. 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. 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. 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. The overdrive settings above Fast are not worth using. 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. VISIT SITE. Resolution: 1920 x 1080. This would still seem a sensible and again might be a response time to use as your requirements for all user-based interactions. Based upon analysis carried out from a productivity perspective we can see that this is still relevant. Was wondering what fellow owners were using for their brightness/contrast settings. JMeter. Seems like it could also be the NanoIPS panel. Response times are difficult to define and even harder to get agreement on with the end-users. 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. 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. 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. New comments cannot be posted and votes cannot be cast. 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. 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. This monitor doesn't handle brightness roll off well, so elements that should be bright are not as bright as they should be. Portrait CALMAN Ultimate, DeltaE Value Target: Below 2.0, CCT Target: 6500K. The analysis above would seem to indicate that the 15 second category is the one that asynchronous transactions fall into. My old monitor was the Asus PG279QZ. 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. Unfortunately when viewing sRGB content there is going to be some level of oversaturation. However the Odyssey G7 is only a gaming display. 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. The reason being that we are not measuring the response time under load against a value that has been agreed upfront. We need to be able to answer these questions: At what point does a response time become unacceptable? 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. So let's see how it performs At 240Hz using the lowest overdrive mode, Fast, it's clear that overdrive is indeed enabled. It is HDR compatible and features 98% DCI-P3 coverage, so we'll see how it performs a bit later. Thank You! Meanwhile, due the way variable overdrive operates on this monitor, the AW2721D is only a mid-range performer at 60Hz. Using a category-based system is useful and scientific enough for the business and development teams to agree on. Join thousands of tech enthusiasts and participate. 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. 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. Alienware AW2721D - D65-P3, tested at native resolution, highest refresh rate The Alienware AW2721D is a great high-end gaming monitor and one that shows the promise of IPS technology for 1440p 240Hz applications. 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. Apache JMeter and 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. You can see how it stacks up here in our performance summary chart, new for this review and something we might use going forward. A delay longer than 2 seconds can be inhibiting to operations that demand a high level of concentration. Input lag is virtually zero, and the build quality was impressive and befitting of its price tag. 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. Your comment has been submitted and will be published once it has been approved. 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. 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 Dell Alienware AW2721D is an impressive 1440p gaming monitor. 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. The good news though, is it is actually available, which we can't say about every new bit of hardware we test these days. 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. 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. 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. This is with a bright and dark object far away on the screen. 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. 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. There are several other little bonuses sprinkled in here as well. I was quite impressed with this display's versatility. With LG IPS panels there is always some discussion on contrast ratio, especially since the early days of monitors like the 27GL850. Again the main benefit is simply a higher refresh rate overall. 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. 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. 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. TechSpot is supported by its audience. 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. Wrapping up our performance testing is a look at HDR. How can response times be defined in the requirements gathering stage? If you enjoy our content, please consider subscribing. 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. 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 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. The analysis above would then seem to be a great starting point for defining your non-functional response time requirements. Alienware AW2721D - Super Fast, Extreme - 240Hz. 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. The use of an LG IPS panel prevents us from getting backlight strobing for added motion clarity. You need to be a member to leave a comment. The display can also sustain over 700 nits for lower window sizes, adding to a decent but not chart topping collection of brightness numbers. 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. The following summarises research conducted in the late 1980s that attempted to map end-user productivity to response times. 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. There is no set generic industry standard for performance response times and there is very little been written about the subject. 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. When this analysis was taking place the concept of service-based architecture and cloud computing was not something that would have been considered. Variable overdrive keeps performance solid across the refresh range, leading to a coveted single overdrive mode experience. 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
