The Asus ROG Swift Professional PG248QP is an especially quick gaming monitor designed for skilled esports avid gamers. It boasts an enormous 540Hz refresh price, serving as a powerful demonstration for the way forward for excessive efficiency, excessive refresh price shows, which we hope will turn into extra accessible within the coming years.
At the moment, if you would like a 500Hz+ monitor, it is LCD panels with both IPS or TN expertise that present such speeds. Asus has opted for what they describe as an “E-TN” panel for this monitor, or “Esports TN,” claimed to be the world’s quickest TN panel and “roughly 50% extra responsive than conventional TN panels.” We already know that TNs are the quickest kind of LCDs out there, making them a logical selection for a performance-focused show, regardless of some sacrifices in shade high quality and viewing angles.
Specs and Design
This show encompasses a 24.1-inch 1920 x 1080 TN panel, with 540Hz achievable by way of an overclocking characteristic within the OSD. It features a G-Sync module from Nvidia, offering adaptive sync help, Extremely Low Movement Blur 2 expertise, and the Reflex Latency Analyzer. Asus has additionally listed DisplayHDR 400 help, although precise HDR {hardware} help is someplace between restricted and non-existent.
Priced at $900, we do not count on Asus to promote many of those, besides maybe to a choose few multiplayer avid gamers that need to attempt it out and have money to burn. Nonetheless, the first aim of this monitor appears to be to reveal the feasibility and worth of 500Hz+ refresh charges, in addition to to offer a little bit of a halo impact for different Asus screens.
Discussing the refresh price, 540Hz is just supported within the newest builds of Home windows 11. Earlier variations of Home windows capped at 500Hz, so updating to the most recent model is important for full performance. It is a minor concern for many avid gamers, but it surely’s price noting for these nonetheless on Home windows 10 or earlier variations.
We additionally observed variations in 540Hz compatibility between Nvidia and AMD GPUs, presumably as a consequence of Nvidia’s proprietary G-Sync {hardware} module. Principally, if in case you have an Nvidia GPU, nothing to fret about, 540Hz works with full variable refresh price help as much as that most. With an AMD GPU, 540Hz additionally works, however you will not get variable refresh price help at that most: even when the whole lot seems enabled, the monitor stays capped at 540Hz as indicated by its built-in refresh price counter. It is solely at 500Hz and beneath that you’ll get full VRR help. Not the most important deal, 540Hz vs 500Hz is simply an 8% distinction, however one thing to concentrate on.
As for the advantages of the refresh price itself, we’ll see the way it impacts movement readability a bit later on this assessment, however even utilizing this monitor for desktop apps it is a huge step up for responsiveness and smoothness over commonest refresh charges of at this time.
Going from 144Hz to 540Hz is evening and day, I do know some folks consider that something above 144Hz is diminishing returns; I disagree, even for one thing so simple as shopping the online and navigating by way of Home windows, 540Hz is considerably smoother and any motion you’re taking or enter out of your mouse feels near-instantaneous in a approach that turns into crystal clear when returning again to the a lot slower world of 144Hz.
We additionally suppose it is a noticeable improve over 240Hz, the refresh price right here is greater than doubled, which results in a corresponding enchancment to latency. Much less of a acquire than from 144Hz absolutely, however when evaluating 540Hz to 240Hz we predict the weaknesses in 240Hz turns into extra obvious than when that refresh price first debuted. The one actual strategy to describe it’s that 240Hz feels slower to make use of than 540Hz – although it is most likely not sufficient of a profit to justify the astronomical worth enhance to entry 540Hz.
The Asus PG248QP makes use of an analogous design to earlier ROG screens of this measurement. Most of its outer surfaces are made of easy gray plastic, which, whereas well-constructed, would not fairly match the anticipated construct high quality for a $900 1080p monitor. The rear panel encompasses a gamery design with an RGB LED illuminated ROG emblem, a typical sight in lots of current screens.
A novel and attention-grabbing side to this design is the brand new base which is adjustable between a wider setup and a extra closed setup. The pondering right here is that esports avid gamers usually like to make use of fairly unconventional keyboard and mouse positions, so having this degree of adjustability caters to many several types of avid gamers. It is a clean and simple transition between the 2 positions, and you’ll set any place between the 2 maximums as properly.
The bottom design would not compromise on the soundness of the monitor although, it is a rock stable construct that additionally contains full ergonomic adjustability for the show itself: all of top, tilt, swivel and pivot is included right here. Nonetheless, the usage of the G-Sync {hardware} module does translate into energetic cooling with a sluggish spinning fan that is audible at shut vary.
You may have the ability to hear it in a useless quiet room, however I discovered it very tough to listen to over my PC’s quiet followers throughout regular operation. The fan did not ramp up and down aggressively throughout my time testing it, which is nice. It is these modifications in velocity and quantity which can be probably the most noticeable and most annoying; this fan is only a fixed low velocity that is close to inaudible.
Connectivity is considerably restricted because of the G-Sync module, packing one DisplayPort 1.4 with DSC and two HDMI 2.0 ports, in addition to a two-port USB hub. The DisplayPort is ok, however the usage of HDMI 2.0 on an costly 540Hz show will not be ok, because it limits these ports to only 240Hz, lower than half of the utmost. I think most individuals will likely be hooking up over DisplayPort however nonetheless, it is actually about time the G-Sync module is up to date to help HDMI 2.1 so that each one ports are full refresh price ports.
The OSD, managed by way of a directional toggle, features a complete characteristic set, with gaming-specific choices like crosshairs and timers. The inclusion of crosshair help in a monitor focusing on skilled avid gamers raises questions on truthful play – is that thought of dishonest? When you’re a professional gamer, tell us within the feedback – the Reflex Analyzer, helpful for Nvidia GPU customers, assesses whole system latency with no need exterior {hardware} and produces extra correct outcomes than PC-side latency instruments.
Response Time Efficiency
The Asus PG248QP contains 4 overdrive settings, the primary of which is off, take a look at the chart beneath – fairly a very good end result for no overdrive – this might beat most different screens with overdrive enabled. However for 540Hz gaming I feel most individuals will need to use the Regular mode at a minimal.
Asus ROG Swift Professional PG248QP – Off – 540Hz
Asus ROG Swift Professional PG248QP – Regular – 540Hz
That is what the Regular mode seems to be like, it is extremely quick. With only a 1.8ms common response time and subsequent to no overshoot, the PG248QP is very suited to taking part in at 540Hz with refresh compliance at 86%. Usually the priority with these tremendous excessive refresh price screens is that the transition velocity is not quick sufficient to maintain up with the refresh price however that completely is not the case right here, even with our comparatively strict measurement standards. This results in very low cumulative deviation for an LCD.
Asus ROG Swift Professional PG248QP – Esports – 540Hz
Asus ROG Swift Professional PG248QP – Excessive – 540Hz
There are two different modes out there, one is Esports which barely improves the common response to 1.6ms but additionally barely will increase overshoot. Visually this mode is not all that completely different to Regular and the cumulative deviation numbers are shut. Then we have now the Excessive mode which pushes as much as 1.2ms on common, however does so at a a lot greater degree of overshoot, so I would not suggest utilizing this mode.
Asus ROG Swift Professional PG248QP – Regular – 480Hz, 360Hz, 240Hz, 144Hz, 100Hz, 60Hz
What’s nice to see is that the Regular mode, which I consider is right for 540Hz gaming, can be glorious throughout all the refresh price vary because of variable overdrive. There’s actually no refresh price the place this show performs poorly, at 360Hz it is available in at 1.9ms, at 240Hz 2.3ms, at 144Hz 2.5ms and 60Hz 2.5ms as properly with mainly no overshoot at any level. Overdrive is not fairly as aggressive at these decrease refresh charges which is why we go from 1.8ms all the way down to 2.5ms on the decrease elements of the vary, however both approach that is glorious efficiency that offers us an elite-tier single overdrive mode expertise.
In comparison with different screens the PG248QP is the quickest LCD that I’ve examined so far. It is 0.5ms sooner than the PG27AQN at its highest refresh price, and over 50% sooner than the XL2566K at a decrease degree of overshoot, confirming Asus claims about an roughly 50% extra responsive expertise than conventional TN panels. And these are among the quickest screens going round, relative to a extra commonplace 240Hz IPS to even some older TN shows, the PG248QP is over twice as quick in each refresh price and response time. Nonetheless total OLEDs are nonetheless sooner, holding a couple of 6x benefit, although no OLED is obtainable at 540Hz.
Common efficiency can be excellent from this Asus monitor, once more confirming its place because the quickest LCD I’ve examined. It is 33% sooner on common than the PG27AQN and achieves this at a decrease degree of overshoot which is extraordinarily spectacular and exhibits that TN nonetheless has a spot out there for excessive velocity. It is also a transparent step forward of the BenQ XL2566K, which is anticipated from a more moderen technology of panel however maybe to not this diploma, and just about something that is not 360Hz or above has no hope of competing outdoors of OLEDs.
Common cumulative deviation additionally exhibits the energy of the PG248QP and its robust mixture of velocity and lack of overshoot. We’re nonetheless seeing a 31% hole between the PG248QP and PG27AQN, and a 50% benefit over the XL2566K. Even at the very same 360Hz refresh price evaluating greatest vs greatest overdrive settings, the PG248QP produced a 39% higher cumulative deviation end result than the XL2566K, and mixed with the PG248QP’s higher tuning at decrease refresh charges, we see a fairly sizable total win to the Asus mannequin. Nonetheless we’re nonetheless a good approach off from LCDs matching OLEDs, a typical OLED panel has a 5x benefit on this metric over the quickest LCD, so it is nonetheless the case that an OLED at a decrease refresh price can match an LCD at the next refresh price in movement readability. They can not shut the hole between 240Hz and 540Hz although regardless of their velocity.
I do not suppose 120Hz gaming is the goal marketplace for this monitor however the PG248QP performs properly there regardless. That is additionally an incredible monitor for 60Hz gaming should you occur to wish this degree of velocity at a low refresh price.
One of many huge promoting factors to the PG248QP along with the 540Hz refresh price is help for backlight strobing by way of Nvidia ULMB 2. The combination into this monitor is a bit more appropriate than with the PG27AQN because it does work with each AMD and Nvidia GPUs: on Nvidia GPUs at a number of refresh charges, and on AMD GPUs at 540Hz. It’s because as I stated earlier, enabling 540Hz on an AMD GPU stops adaptive sync from working, and ULMB 2 requires adaptive sync to be disabled for it to perform in any respect. So there is a small quantity of fine information there for AMD avid gamers that need to pair this show with their GPU.
For Nvidia GPU house owners there’s better compatibility and help for a number of refresh charges, though you may nonetheless want to make use of ULMB 2 at mounted refresh charges, and there is a surprisingly restricted vary of selections. ULMB 2 solely works all the way down to 360Hz, at 240Hz and decrease refresh charges the choice is greyed out, compared to the PG27AQN that supported it all the way down to 144Hz. BenQ’s XL2566K with DyAc+ works all the way down to 100Hz. So should you wished to make the most of the center a part of the refresh vary and backlight strobing concurrently, say your sport would not run at 500 FPS in your GPU, then you definately’d be a lot better off with the XL2566K as a substitute.
When you possibly can allow it, the movement readability offered by the PG248QP and ULMB2 is superior to that of the BenQ XL2566K utilizing DyAc+ each at their most refresh price, 540Hz and 360Hz respectively. The PG248QP has barely much less strobe crosstalk and a barely clearer picture, though each are nice. When turning the PG248QP all the way down to 360Hz to get a matched refresh price comparability, the hole narrows between the 2 fashions however I might nonetheless give the general edge in readability to the PG248QP, it actually does have glorious movement readability that must be the very best I’ve seen. Something beneath this refresh price the BenQ wins by default because it really helps strobing at these refreshes.
However the advantage of the PG248QP extends past backlight strobing because the non-strobed 540Hz picture can be extremely spectacular when it comes to readability. Evaluating the 540Hz picture right here to 360Hz, whether or not from the XL2566K or the PG248QP turned all the way down to 360Hz, the 540Hz picture is noticeably sharper and fewer blurry; the textual content for instance whereas not crystal clear is extra readable on the 540Hz picture. In comparison with 240Hz the distinction in blurriness could be very apparent in favor of 540Hz.
The ULMB2 implementation additionally helps completely different strobe timing and lengths so you possibly can modify the place of greatest readability and the general readability, though truthfully the distinction between 100 and 10 for readability could be very laborious to identify. Utilizing the default strobe timing the center part was clearest and the underside was barely blurrier, though the vary to which you get good readability is mostly glorious.
Now a non-strobed 540Hz picture does look nice however it may’t beat a strobed 360Hz picture, so the very best picture high quality will at all times be discovered with 540Hz and strobing used on the identical time. However the greater refresh price choice is extra versatile as you possibly can select to make use of strobing at a hard and fast refresh, or get the nonetheless glorious readability on supply at a variable refresh close to 540Hz. Opting to not use strobing could possibly be the higher selection if you cannot constantly hit 500 FPS, as strobing solely actually works properly when the refresh price and body price are matched.
Enter latency with the PG248QP is elite, providing just under a 1ms processing delay at the side of a brilliant excessive refresh price and quick response occasions. This offers the PG248QP glorious responsiveness together with an total low latency expertise, matching the quickest OLEDs which acquire a bonus as a consequence of their elite response occasions. We’re speaking about lower than 5ms of whole latency, which is extremely good.
Energy consumption is nothing superb at 36 watts, which is generally attributable to the G-Sync module which isn’t very environment friendly. It makes use of round 12 watts greater than the BenQ XL2566K, however lower than the PG27AQN for example.
Coloration Efficiency
Coloration House: Asus ROG Swift Professional PG248QP – D65-P3
For shade high quality you is likely to be shocked to find this panel is vast gamut, sporting 95% protection of DCI-P3 and an total 70% protection of Rec. 2020. This is not the widest gamut, it is just about the minimal kind of protection wanted for a correct vast gamut expertise, but it surely does present one the place the XL2566K and a number of other different 1080p screens don’t.
Default Coloration Efficiency
Manufacturing facility shade efficiency is respectable, greyscale deltaEs could possibly be a bit tighter however total fairly cheap, whereas saturation and ColorChecker outcomes are glorious because the monitor makes use of sRGB gamut emulation for SDR content material by default. This prevents oversaturation from the manufacturing facility, so usually the picture high quality is fairly correct in comparison with most different gaming screens.
And you will see that in these charts, the PG248QP is above common for grayscale from the manufacturing facility, and among the best screens for ColorChecker. So regardless of providing a TN panel and being primarily geared in direction of esports avid gamers, Asus are nonetheless guaranteeing the visible expertise is respectable from the manufacturing facility.
OSD Tweaked Coloration Efficiency
Calibrated Coloration Efficiency
This monitor additionally affords full management over white steadiness and different settings within the sRGB mode, and means that you can change between sRGB and vast gamut utilizing the OSD settings. This allowed me to tighten up efficiency barely utilizing {hardware} controls. Nonetheless for the very best expertise you may must carry out a full software program calibration, I used Calman for this and the outcomes had been fairly good because the panel has full protection of sRGB and was comparatively properly calibrated from the manufacturing facility. I would not suggest it for shade correct vast gamut work however even for the occasional little bit of vast gamut viewing it is not horrible.
Brightness is excellent at 420 nits after calibration which is within the ballpark of most different 1080p screens although notably higher than the XL2566K. With backlight strobing enabled you may get simply over 300 nits with the longest pulse width, round 30 nits on the shortest pulse, and 150 nits with the center 50 setting. The XL2566K does 330 nits strobed so both approach there may be sufficient brightness right here whether or not strobed or not strobed. Minimal brightness of 41 nits is fairly good as properly.
Distinction is surprisingly good from this TN monitor, my unit hit 1376:1, 26% greater than the XL2566K and an all spherical nice quantity from a non-VA LCD panel. Black ranges aren’t particularly darkish and naturally to get this end result it’s essential to view the panel useless on, however you will not be getting a distinction drawback simply because it is a TN monitor.
The most important draw back to picture high quality from this panel are the viewing angles, that are horrible. You actually need to view this show useless on to get a very good expertise, any slight off-axis viewing angle within the horizontal or vertical course results in a big gamma and brightness shift, resulting in a very washed out picture. Colours are additionally affected at off angles. That is the place a TN panel can look very dangerous subsequent to an IPS or different kind of LCD, as you possibly can view an IPS from a barely off-axis angle and nonetheless get an incredible expertise, whereas a TN seems to be comparatively horrible underneath the identical circumstances. So make sure that your setup is optimized the place you’re viewing the panel precisely in that very slim viewing angle candy spot.
Outdoors of viewing angle points uniformity is cheap, definitely ok for gaming and when considered optimally you should not see an excessive amount of backlight bleed.
HUB Necessities Guidelines
Asus advertises this monitor properly, though together with HDMI 2.0 as a substitute of HDMI 2.1 is annoying. The colour efficiency specs are fairly good, though promoting a 0.2ms response time is a bit deceptive regardless of this being a really quick panel – on common the show is extra like 2ms. The shortage of backlight strobing help beneath 360Hz additionally lets it down.
Asus additionally bizarrely advertises this as being HDR succesful with DisplayHDR 400 help, though I do not suppose any esports gamer shopping for this panel would really care about HDR in any respect.
The show would not help true HDR, because it would not help any type of native dimming, resulting in a really low distinction ratio for HDR and weak brightness. Nonetheless I did not spot any points or defects with the panel, and basically the panel high quality is sort of good.
540Hz Gaming is Superior
Total, the Asus ROG Swift Professional PG248QP is a type of screens that actually will get to impress us with its distinctive movement readability. As the primary 540Hz show we have used, its responsiveness and smoothness are a delight.
This monitor stays remarkably clear when gaming at its highest refresh price, and we proceed to be amazed by the impression of even greater refresh charges. Whereas some may argue that we’re within the realm of diminishing returns, we disagree. The variations in comparison with 360Hz had been noticeable for us, and much more so in comparison with 240Hz, which many take into account a excessive refresh price at this time.
Whereas some may argue that we’re within the realm of diminishing returns, we disagree.
Along with the excessive refresh price, the PG248QP boasts the quickest response occasions we have measured on an LCD panel. It considerably outperforms earlier leaders on this class, just like the BenQ XL2566K, providing a superb, quick, low overshoot expertise in any respect refresh charges.
It is greater than able to dealing with 540Hz, it is elite at decrease refresh charges and it has low enter latency as properly. At the moment, solely OLED panels are sooner, however with OLEDs maxing out at 240Hz, you get superior movement readability from a 540Hz LCD.
Asus enhances this with ULMB2, which delivers the very best movement readability we have seen on this 540Hz panel, making the PG248QP the best choice for each strobed and non-strobed readability. This characteristic’s limitation at decrease refresh charges like 240Hz or 144Hz is a minor setback, however we suspect anybody buying this show is aiming to play at or above 500 FPS – which is feasible in some multiplayer video games offered you have got highly effective PC {hardware}.
I used to be additionally pleasantly shocked by some facets to picture high quality, together with its good distinction ratio, vast gamut help and nice manufacturing facility calibration. Nonetheless, the poor viewing angles, a attribute of TN panels, usually nullify these advantages. Except considered head-on, you are prone to expertise a extra washed out picture, so it is laborious to suggest it for something apart from its velocity and movement efficiency.
Whereas the picture readability is spectacular, the PG248QP feels extra like a glimpse into the way forward for show applied sciences. Priced at $900, it is difficult to suggest to the common gamer. Even for these in search of a premium esports monitor, the value is steep, relegating it to a distinct segment market.
Although it surpasses the BenQ XL2566K in efficiency, the BenQ’s $600 price ticket – already excessive for a 1080p monitor in 2023 – makes it a extra enticing choice for a lot of, particularly for avid gamers eager about backlight strobing the place the PG248QP affords solely a slight enchancment. We consider the Asus ROG Swift Professional PG248QP needs to be priced no greater than the present XL2566K, prompting a worth discount for the BenQ. That might most likely tempt a portion of the esports crowd to contemplate it. At $900 although, get pleasure from this look into what’s going to come sooner or later, however maybe look ahead to that future to reach moderately than leaping in proper now.
