The ASUS Republic of Gamers (ROG) line includes everything you want for building a high-end gaming PC: GPUs, Motherboards, Keyboards and Mice, Sound Cards, Headsets, and now Monitors. The ROG Swift PG278Q is a 27” WQHD display that has both a 144Hz maximum refresh rate and NVIDIA G-SYNC. Combining both of these technologies provides the potential of a silky-smooth image that doesn’t get choppy if the frame rate happens to drop in demanding sequences.

My prior demonstrations of G-SYNC involved displays that fell below a 60Hz refresh rate. Even when falling down to 40-45fps, the G-SYNC displays manage to remain smooth when compared to a standard 60Hz display. With a 144Hz display, G-SYNC enables you to run at these very fast refresh rates without noticeable stuttering or tearing if your refresh rate falls below that. You might have the GPU power to run at 144Hz most of the time, but if you suffer slowdown during certain sequences the ASUS ROG will still appear as smooth as it did before.

Ergonomically the ASUS ROG offers a very well designed experience. The display has good height adjustment, tilt, swivel, and pivot. Since it is a TN panel and prone to color shifts when you move off-axis, being able to set it up to be perfectly even with your eyesight is a very good thing. There are a pair of USB 3.0 ports on the bottom of the rear panel, good for a keyboard or mouse, but none on the side to provide easy access for flash drives and other accessories.

The worst ergonomic feature of the ASUS ROG is that it utilizes an external power supply brick. The external brick is compact compared to others that have passed through, but it still means yet another cable and device to have to deal with on a desktop.

The On-Screen Display for the ASUS ROG is good though not excellent. It offers quick access to a few items, like refresh rate, but to do so it uses icons on the screen. Since the keys are on the back of the monitor, unless your face is level with the lower bezel (an unlikely occurrence) it is hard to determine which button is the correct one. If the buttons were on the front this would work well, but I just found myself always hitting the wrong option. Simply going to the main menu and selecting the item there is faster.

The main menu is controlled with a 4-way joystick on the back of the display. This is nice and easy to use, and lets you move around the menus quickly. The layout is a nice three-column variety that lets you see which submenu you are in without having to navigate all the way back out, which is nice. Menu systems have come a long way since I started reviewing monitors and the ASUS would beat anything I had to look at four years ago.

    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"
  • DiHydro - Friday, February 13, 2015 - link

    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:
  • 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.
  • D. Lister - Thursday, March 12, 2015 - link

    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!!
