To compare the X32 X3’s performance, I’ve rounded up a somewhat diverse group. There’s only one other 4K dual-mode screen in my database, the Asus PG32UCDP. I also have the QHD 480 Hz PG27AQDP. The others are Alienware’s AW3225QF, Aorus’ FO32U2P, and Philips’ 27M2N8500.
Pixel Response and Input Lag

The response test is cut and dried. Faster refresh rates mean the draw time is less. 480 Hz is the quickest at two milliseconds, but the rest aren’t far behind at three and four milliseconds. Visually, it’s almost impossible to tell a difference, all three refresh rates represented here look the same in terms of smoothness and lack of motion blur. And no surprise, changing the dual-mode screens between 240 and 480 halves the panel response time.
Things get interesting when total lag is calculated. The current record holder is Philips 360 Hz 27M2N8500 which takes just 10ms to respond to a control input. The next three screens require 480 Hz to come close. Remember that the Philips runs at QHD resolution when accomplishing this feat. Also note that 240 Hz is nothing to sneeze at. It still delivers lag low enough to be imperceptible. The X32 X3 is the quickest at 240 Hz with a 19ms score.
Test Takeaway: All the monitors are very fast, but the X32 X3 is one of the quickest OLEDs you can buy. Though it is 2ms slower than the PG32UCDP in 480 Hz mode, it’s 4ms faster at 240 Hz. That makes the Acer a better bet for the long term. No matter which of these you choose, your gaming experience will be a spectacular one.
Viewing Angles
Viewing angles of OLED panels are almost boringly similar, but I could see a tad more color shift when photographing the X32 X3. There is a green tint visible, but there is no change in brightness or gamma. The tint is harder to see in actual content, this is a torture test after all. The top view is very clean with a small reduction in gamma and brightness.
Screen Uniformity

The X32 X3’s last place finish in the uniformity test should not be seen as a negative. It still has visually perfect rendering of gray and color field patterns. My meter picked up a slightly darker value in the lower right corner which is the main reason for the 9.35% score.
