Response, Input Lag, Viewing Angles and Uniformity

The PX277 OLED MAX’s comparison group is all 27-inch QHD 240 Hz OLEDs. We have the Dough Spectrum Black 27, Acer X27U, Asus PG27AQDM, Corsair 27QHD240 and AOC’s AG276QZD.

The PX277 OLED MAX may be less expensive than the other screens here, but it gives up nothing regarding performance. It draws the screen in 4ms, the same as Dough and Acer. And it has super low input lag. With 19ms total lag, it is in the fastest group of monitors I’ve tested. What’s the record? I recorded 17ms total lag from a 360 Hz MSI NXG253R in 2021. It’s a 25-inch FHD IPS screen. The Pixio impresses by matching the best OLEDs I’ve tested from mainstream manufacturers. Smooth? Absolutely. There is no motion blur over 200fps. The only bummer is that users running at lower speeds have no strobe option. At 144 Hz and below, you’ll see some blur.

Test Takeaway: The PX277 OLED MAX matches speed with the fastest gaming monitors available. Its video processing is without flaw. The lack of a strobing option might be an issue for users with less stout video cards but if you can run QHD at 200fps, you’ll be golden. This is one quick display.

Viewing Angles

The one advantage non-QD OLEDs have is less color shift and light reduction at off-axis viewing positions. The PX277 OLED MAX has no reduction in output and color goes just a tad cool. QD screens go red and lose around 10% of their light. These are minor points, because the worst OLED will still trounce the best LCDs. This is excellent performance.

Screen Uniformity

Buyers of the PX277 OLED MAX don’t have to worry about screen uniformity. My sample measured an impressive 3.34% deviation which is essentially nothing. 10% is where you might see an issue in a totally dark room. You won’t see any hotspots from this Pixio.
