TFTCentral reviews ASUS ROG PG278Q – 1440p GSYNC!

Our friends at TFTCentral has published a review of the ASUS ROG PG278Q, with 2560×1440 resolution, GSYNC and ULMB!

ULMB is the sequel to LightBoost, and is found in GSYNC monitors. This is the highest resolution monitor now shipping with LightBoost-type functionality! And the big bonus is that strobe length is adjustable – all the way to clearer motion than LightBoost 10%!

We are also getting this monitor later this summer, for a Blur Busters-focussed review of its “Better Than 60Hz” capabilities, including its Ultra Low Motion Blur (ULMB) mode.

    Can someone confirm that the ASUS ROG Swift PG278Q uses the brighter-than-ULMB-strobing version AKA Lightboost, when in actual 3D mode? TFT Central reported a max brightness of just 120 cd/m2 for the PG278Q while in ULMB mode which is totally fine for most people in 2D mode, but that’s not enough for most people in 3D mode where the glasses make the screen appear dimmer than it actually is. My ASUS VG248QE approaches 200 cd/m2 in Lightboost strobing mode, and this is enough to help make up quite a bit of the 3D glasses dimming effect.

    NVIDIA’s 3D Vision 2 (or just general 3D gaming) is probably the most underrated features, and one of the most amazing features in all of gaming, but because it’s so under-rated there are hardly any mentions of things like actual 3D mode, 3D mode brightness VS 2D mode brightness, ULMB VS Lightboost, can a monitor even do 2 different strobing modes (ULMB and Lightboost) depending on if it’s in 2D or 3D mode, etc. etc.

        The ULMB test was done post calibration and interestingly enough the brightness actually increased when ULMB was turned on.

        brightness after calibration with ULMB OFF was 120cd/m2 and after calibration with ULMB ON was 134cd/m2

          Since brightness is so important in ULMB test it should be tested with max brightness as well. Calibration if of secondary importance to people this monitor is aimed at.

          The VG248QE in Loghtboost strobing mode approaches a brightness of 190-ish cd/m2, and according to a review achieves about 165 cd/m2 after proper calibration. 165 – 190 cd/m2 is definitely enough to make up for quite a bit of the dimming effect of the 3D glasses but 100-125 cd/m2 seems like it would be abysmalwhen combined with the 3D glasses…The ROG Swift detects when in NVIDIA 3D Vision 2 mode and goes into “Lightboost” mode instead of ULMB (base turns green), would you be able to check the max brightness and the calibrated brightness of the monitor while in actual Lightboost mode rather than ULMB?

          It seems that Lightboost strobing and ASUS’s ULMB mode are slightly different, and Lightboost may offer much better brightness while not preserving nearly as much colour accuracy, black levels, etc. as ULMB mode….

          • Chief Blur Buster says:

            27″ LightBoost monitors such as the ASUS VG278HE has much dimmer brightness than the 24″ ASUS VG248QE.

            LightBoost brightness is similar to ULMB brightness, at similar strobe lengths on the same screen, when both are calibrated for maximum brightness.

            There is crosstalk and color differences, but the peak brightness is pretty similar.

    First off, great review!

    I’m tempted to buy it for 144Hz and the ~78% more pixels.
    Gsync also sounds great for newer games where 144+ constant FPS isn’t achievable (especially at this resolution) but….

    We cannot use ULMB or even lightboost at 144Hz??

    This means the the main difference between my VG278H (for which I paid a similar price when it was released) and this will be the resolution which is nice, but not worth ~$800+.

    For those of you who don’t have a lightboost monitor though, this would probably be a worthy upgrade.

    I have also read the review. Sounds like a great gaming monitor is about to come. Very good news for gamers. Thanks for sharing the news.

  4. d3n.Swiper says:

    So, no support for GSYNC and ULMB at the same time?
    So it would be something like
    a) If constant 120fps -> ULMB+120hz+VSYNC OFF
    b) If FPS dips below -> GSYNC
    or not?

    I’m loving this monitor so far. G-SYNC is incredible. Goodbye tearing and input lag. It’s my first ULMB (or Lightboost) monitor and I was very excited to test it but frankly, it seems like a useless feature. It works brilliantly on the UFO test with a black background but on lighter backgrounds it creates a trailing “ghost” and there’s still some motion blurring. It looks worse in every possible way to simply having overdrive set to “Normal”. The fact that it kills brightness down to 100 cd/m2 and G-Sync doesn’t work with makes it totally useless. Am I doing something wrong?
