Acer's XB270HU is one of the only IPS screens that can run at 144Hz. We'll see how the G-Sync monitor fares in our video performance and gaming tests.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Color Gamut And Performance

For details on our color gamut testing and volume calculations, please click here.

In the XB270HU's Standard mode, we see good accuracy in the color saturations, but there are a few hue issues in the secondary colors, especially magenta. Since the gamma is where it should be, all that's needed to fix things is a grayscale calibration. Bringing the white point in line will pull the secondaries onto their targets and firm up the luminance levels too.

The XB270HU omits the color management system found in the XG270HU but obviously it's not needed here. Every color is on target for both saturation and hue, and luminance levels are near perfect. Aside from a slight over-saturation in the red primary, this is an excellent chart.

Now we return to the comparison group.

Since the Overlord Tempest was calibrated through a LUT, the XB270HU is the winner of the calibrated-by-OSD competition. Only an expensive pro-screen will post a better result than this. Its color accuracy obviously outperforms most gaming monitors.

Gamut Volume: Adobe RGB 1998 And sRGB

If gamut volume is an important metric in your work, then the XB270HU offers a little bonus red bringing up the total to over 107 percent of sRGB. The Monoprice sits atop the ladder thanks to its Adobe RGB gamut, which may not be ideal for gaming or entertainment purposes.

    I was nervous after hearing all the QC issues but either they fixed whatever issues people were reporting And I got a perfect one out of the box on the first try (was ready to RMA once or twice because I really wanted this monitor to work as advertised).

    Have others been getting XB270HU out of the box with no dead pixels or noticible light bleed?

    Yes... It was expensive but this is hands down, the best monitor I've ever owned.

    "*either they fixed the QC issues or I got lucky"

    Is what I meant to say. First comments get me a little overenthused sometimes!

    When Acer announced this and after I saw the tftcentral review I had my heart set on this. But then as people started to get them I heard about the issues. The QC issues seem way above average. Unless there is proof of a real fix I'm staying away from this monitor. Sad. Cuz it has/had so much potential. The specs are what us fps gamers want.

    I'd like more reviews to inform people about IPS glow. IPS panels are gerat for image and viewing angles but become completely useless in the dark. To me, they look like the first generation of LCDs with no ambient light. So, people who play games or who watch movies in the dark should stay away. TN panels don't have this issue. And this is why I don't really understand Tom's for recommending IPS for gaming with such conviction. It should come with an asterisk at the end saying: "If you don't play in the dark".

    Great review, and an even better panel. I have seen some photos of some pretty questionable panels as far as backlight bleed and 'IPS Glow' go. Purchased this panel near the end of July and at 45% (a bit too high even) brightness, there is no noticable backlight bleed or orange glow present. I like to think they've probably improved their process in manufacturing these panels over the last 6 months, but I could be wrong.

    Not to mention Acer is pretty good about the RMA process and replacement panels. Favorable to ASUS's "Under ten dead pixels is normal and not covered under warranty" policy...

    $800 for an Acer?

    It may be a nice monitor but that is still a hard sell given it is an Acer.

    I feel like I need to do a side-by-side with my PG278Q. The contrast on this Acer is amazing for an IPS in that price range I did love my Acer HN274H from the pre-G-sync days...

    if it was 1ms, I think it would be worth it.

    I was thinking the same thing but the difference between that and the ROG Swift is only 2ms black to white. This is more where the rubber meets the road.

    Wuuuut?! Where did the days go where we used to have to drop a lot of money on our favorite set of monitor compromises? I really want to see this in person to feel whether it's as good as it seems :)
