Why you can trust Tom's Hardware
To compare the G34WQi, I’ve grouped five WQHD panels: ViewSonic’s XG341C-2K, Monoprice’s 44394, Philips’ 34M2C7600, HP’s Omen 34c and ASRock’s PG34WQ. The ViewSonic and Philips are premium Mini LED panels priced over $1,000.
Pixel Response and Input Lag
Click here to read up on our pixel response and input lag testing procedures.
Response times and refresh rates usually go hand-in-hand, but the ViewSonic is unusual because it takes 7ms to draw a full white field while running at 200 Hz. The 180 Hz G34WQi comes in at 6ms, which is respectable. Unfortunately, its overdrive undershoots, leaving visible black trail artifacts behind moving objects. Blur is minimal but you’ll see some breakup in fast camera pans. Input lag is the good part of the G34WQi’s story at a class-leading 26ms. The monitor is quick and precise when aiming and moving.
Test Takeaway: Aside from a weak overdrive, the G34WQi delivers decent performance with quick control response. Rapid movements show some breakup of detail thanks to overdrive undershoot. The blur reduction (MPRT) is a viable alternative that further reduces blur, but the black trail artifacts cannot be removed.
Viewing Angles
The G34WQi looks better in the viewing angle photos than other VA monitors. You can see a 40% light reduction with a green shift in the side view. Looking from the top, light drops by 50%, detail clarity is reduced by low gamma, and there is a red/green tint. The G34WQi isn’t a great choice for sharing but for a single user, it delivers good imagery from edge to edge.
Screen Uniformity

Xiaomi does not skimp on quality control even though the G34WQi is a value-focused monitor. A 7.62% deviation means there are no visible issues. I saw no hotspots, glow, or bleed in my sample. This is excellent performance.
