The X34 X0 has a higher refresh rate than its most recently released competitors, so it comes out of the gate with an advantage. Other assembled competitors include Titan Army’s C34A1R, Gigabyte’s GS34WQC and G34WQCP, HP’s Omen 34c G2, and Xiaomi’s G34WQi.

Pixel Response and Input Lag

The X34 X0’s 200 Hz doesn’t make it any smoother than a 165, 180, or 190 Hz monitor. They all draw a full white field in the same 6ms. But Acer and HP’s overdrive are a cut above the others. There is almost no motion blur from either screen. It’s a bummer that the X34 X0 can’t have Adaptive-Sync and overdrive running at the same time.

Acer also ties HP in the lag test with a fast 21ms of total delay. This is well below what most gamers can perceive, and, in my observation, there was no hesitation to any control input. Titan Army and Gigabyte manage 20ms, which in practice is not a perceptible difference.

Test Takeaway: The X34 X0 is extremely smooth and responsive with input lag low enough to be competition worthy. Its only flaw is that you can’t run the overdrive with Adaptive-Sync. But you won’t need AS if you can keep the frame rate above 144fps. Still, this is an issue that the competition doesn’t share.

Viewing Angles

VA isn’t the best screen tech for off-axis viewing, but the X34 X0 is a bit better than average. At 45 degrees to the sides, the picture darkens by around 20% and has a slight red/green tint. Gamma is consistent, which means fine detail will remain visible. From the top, the picture washes out and gets even warmer with a 40% reduction in brightness.

It’s tricky to get FALD screens perfectly uniform, especially with 1,152 dimming zones like the X34 X0. My sample performed well on this test, scoring 10.66%, right at the visible threshold. I couldn’t see anything to complain about, but the meter showed a little extra light in the top-right corner.
