The GS34WQC is a bit unusual in this category with its 135 Hz overclocked refresh rate. Most 34-inch WQHD screens run at 144 or 165 Hz. The group consists of Xiaomi’s G34WQi, HP’s Omen 34c, Monoprice’s 44394, Philips’ 34M2C7600 and ASRock’s PG34WQ.

The GS34WQC ties for least expensive in the group with the 180 Hz Xiaomi. And looking at the numbers, it is a compelling choice. But Gigabyte’s video processing is far superior. Though the screen draw and input lag scores keep it out of first place, its motion resolution and quality are clearly better. The overdrive is what makes the difference. I would choose the GS34WQC every time. The lower refresh rate doesn’t affect input lag. 29ms is fast enough to keep up with the 165 Hz monitors here.
Test Takeaway: I was initially skeptical of the GS34WQC’s 135 Hz refresh rate but its superb overdrive more than makes up for any deficit in frame rates. There is no sacrifice in input lag over 165 Hz screens and though the Xiaomi is a tad quicker, its motion resolution is visibly lower. And the GS34WQC costs less than all the others with the Philips taking the title of most expensive at over $600. In fairness, though, it is a Mini LED panel.
Viewing Angles
Viewing angles are the reason for IPS’s popularity. Though VA delivers more contrast, it doesn’t look as good off-axis. In the GS34WQC’s photos, the side view is 50% dimmer with a strong red shift. Gamma remains solid, so detail will still be clear. The top view is very red with the same 50% drop in brightness and much lower gamma. Definitely do not use your GS34WQC from above.
Screen Uniformity

A low price doesn’t have to mean poor quality control. The GS34WQC has visually perfect screen uniformity when displaying a black field pattern. There was no bleed or glow on any part of my review sample. This is excellent performance.
