ASUS ROG Swift PG278Q G-SYNC Monitor Review
by Chris Heinonen & Jarred Walton on February 13, 2015 10:00 AM ESTBrightness and Contrast
Set to maximum output, the ASUS ROG can output up to 352 cd/m2 with a 50% APL pattern. This is far too bright for night time use, but will work well to overcome reflections and lights during the day. Setting the brightness down to the minimum level the output falls to 45 cd/m2. This level is actually very good as it is sufficiently dim for a completely dark room, but not so dim as to be unusable. For any environment, the ROG has a level of backlight flexibility that will work for you.
Black levels are pretty good for a TN panel with the ROG. At the maximum backlight we see 0.3916 cd/m2 of light using a black 50% APL pattern. Going to the minimum backlight level this falls down to 0.0516 cd/m2. As always we use APL patterns because they prevent the screen from completely turning off the backlight to trick the test, and it is more like the real world than a full field pattern is.
The contrast ratios these readings produce are between 882:1 and 901:1. For a TN panel, I think these are pretty good overall. IPS and especially VA panels can do better, but for TN the numbers are solid.
The ASUS ROG has good flexibility for a the backlight and produces good overall results for brightness levels and contrast ratios.

Unfortunately you're misinterpreting refresh rate for response time.The ASUS monitor has 1ms response time while the
Acer: "one of the world’s first IPS monitors with a response time of only 4ms G-to-G"

If it is 4 ms Gray to Gray, that means it should be able to achieve 144 Hz if the screen is refreshing at that. Required response time for 144 Hz is 6.944... ms. 4 ms on the dot would get you 240 Hz, and of course 1 ms should equal 1000 Hz.That does not mean these displays will not have input lag, another issue for FPS and fast paced games, or terrible picture quality, an issue for everyone and movies especially.

If they advertise "4ms GtG," it is most likely closer to a 6ms average transition time. If you read the reviews on TFT Central, when they measure actual pixel response times, they are often about 2-3ms higher than the reported value. For example, the Swift is a supposed "1ms GtG" panel, but in practice the average transition time was about 3ms.In reality, the ghosting effect of slow pixel response times could be a minor problem for an IPS running at 120+ Hz, however... I'd take an IPS running at 120Hz over one at 60Hz any day... the blur caused by ghosting is minimal compared to the blur caused by 60Hz persistence compared to 120Hz persistence.
The one thing that incredibly fast pixel response times allow for is strobing, which makes LCD behave practically like a CRT display, meaning practically 0 motion blur. For now, IPS doesn't look like it can transition fast enough for a clean strobe.

Sorry, I misread low for lower. TN is still the quickest to be sure, though as DiHydro points out, IPS should now cleanly manage transitions at 120 and 144Hz.theunwarshed - Saturday, February 14, 2015 - link
that's advertised, the true response time is closer to 3ms on "normal" OD settings for the Swift per: http://www.tftcentral.co.uk/reviews/asus_rog_swift...theunwarshed - Saturday, February 14, 2015 - link
if we're talking total input lag (signal processing+response time) than BenQ's XL2720Z is actually a little faster. it's a TN 144hz, 3d vision w/o g-sync @ $450. a better deal imo than the Swift.mackanz72 - Monday, February 16, 2015 - link
27" @ 1080p? And i thought 24" @ 1200p was bad.How in the world is that a better deal?
I'm not saying the Swift is a good deal, since it is really a crappy piece of junk seeing all the quality issues it has. Online shops are stockpiling refurbished units from Asus that few wants to touch with a ten foot pole.
But 27" and only 1080p in 2015? No way.

One hopes that AMD can finally deliver it's freesync vaporware, but no one should hold their breath.I think Asus and their ROG is hoopla is half the tax.
Next we'll get a $300 over normal price 1nf1n1ty gamerz gsync so all the drooling ad controlled robotic braggers can forum it up.
Well at least it's not quite as bad as apple fans.

AMD will indeed deliver FreeSync. They've got a bunch of monitor manufacturers onboard for this (who admittedly would just need to add a few extra lines of code to their firmware for this, but still), so they can't just back out now.<speculation > The problem is with the way FS works. When the framerate is reasonably consistent, it would work fine, but if the framerate is jumping around, there would probably be some stuttering. Ultimately I suppose, as per AMD's MO of late, it would be another compromise between price and quality.</speculation>

I paid the nVidia tax... I was one of the lucky folks that got this monitor when it first came out. Boy was that an adventure!!! Constantly trying to find someone that had a stock of it. Anyways, I was also fortunate enough to get a great display in terms of backlight bleed etc. I have had ZERO issues with mine. Now that I have seen G-Sync in motion... I would have gladly paid $1,000 for this monitor. Fortunately, I got mine for $800. This monitor is truly the best gaming monitor I have ever owned!!! For me, it even beats out my old trusty Sony GDM-500 display and that's saying something!!
