Asus ROG Swift PG278Q 27-inch G-Sync Monitor Review

Results: Color Gamut and Performance

Color gamut is measured using a saturation sweep that samples the six main colors (red, green, blue, cyan, magenta, and yellow) at five saturation levels (20, 40, 60, 80, and 100%), yielding a more realistic view of color accuracy.

Out-of-box color is quite good. Only blue shows any significant deviation from its target. You can see the 80- and 100-percent saturations are too high. Fortunately, luminance has been reduced to compensate. And since the white point is pretty close before calibration, there aren’t any serious hue errors.

Calibrating grayscale brings the magenta secondary in line nicely. The saturation errors are still there, though. Only a CMS can fix those issues. We realize the difference between our before and after charts is small. The PG278Q has very good color whether you calibrate or not.

Now we return to the comparison group:

Our adjustments reduce the color error from 2.61 to 2.13 Delta E. It’s a small improvement that means Asus' Swift is pretty close in its stock form.

Gamut Volume: Adobe RGB 1998 And sRGB

There are basically two categories of displays in use today: those that conform to the sRGB/Rec. 709 standard like HDTVs, and wide-gamut panels that show as much as 100 percent of the Adobe RGB 1998 spec. We use Gamutvision to calculate the gamut volume, based on an ICC profile created from our actual measurements.

Because of slightly oversaturated blue and magenta results, the sRGB gamut volume is a little over 100 percent. It won’t matter for gaming, and we doubt many photographers are considering the ROG Swift as an addition to their editing suite. We had no problems using the monitor for general productivity on the Windows desktop.

    Nice! This is great since I am one of those picky guys that believes that 30fps doesn't bring a good enough gaming experience.

    But one thing I do hope for is a 144hz g-sync IPS monitor, ever since I've gotten my new Asus MX239H the ips makes a huge difference in games.

    But besides that, it is a glorious monitor, resolution is great, 144hz, and of course g sync makes it a wonderful monitor.

    But really $800? I know that it is one of the few g sync equipped monitors, but you can buy a 4k monitor for $650!

    Anybody knows if the incompatibility between G-Sync and ULMB is something that will get fixed or is here to stay?

    Pretty unlikely. ULMB requires a static refresh rate, because it has to strobe the monitor at a constant rate. GSYNC would mean that it would have to strobe in time with each frame, at a variable rate. You would introduce a lag time on the strobing if you tried to do this, since it would be at a variable rate instead of a constant one.

    I know it's expensive for 2560x1440, I know it's not IPS, but to get the refresh rate @144hz and the 1ms g2g and g-sync? The few reviews for this monitor that are out there are all glowing. Come on, Asus, release the thing already, I've been waiting since the Jan announcement for this monitor. Shut up and take my money!!!

    Asus has said on Twitter it should be in the US by the end of August. I can't wait for this, I'm checking newegg everyday to see when it shows up! I hope they have enough of these coming in because there seems to be a lot of people waiting to buy this monitor.
