Why you can trust Tom's Hardware
34-inch ultra-wide monitors run a wide range of refresh rates. A look through my test database revealed speeds from 135 to 180 Hz. The G34WQCP adds a little value with its 190 Hz overclock. The other screens are Xiaomi’s G34WQi, Lenovo’s R45w-30, HP’s Omen 34c, Philips’ 34M2C7600 and Gigabyte’s GS34WQC.
Pixel Response and Input Lag

Panel response times are in lockstep with refresh rates as expected. 190 Hz only provides a tad more smoothness than 180. You won’t likely see a difference with the naked eye. In this category, I would recommend going with 165 Hz or faster.
The input lag test is where the G34WQCP pulls away from the competition. It is significantly more responsive to control inputs than the Xiaomi. While you might be tempted by the Philips’ Mini LED backlight and zone dimming, the G34WQCP is a superior gaming screen based on this result alone.
Test Takeaway: When speed is your top priority, the G34WQCP is a good bit quicker than like-priced competitors. You can find faster 34-inch screens but only at a premium. For $350, it’s a top choice.
Viewing Angles
VA screens require some latitude when viewing angles are considered. The G34WQCP’s photos reveal a red tint and light reduction to the sides with lower gamma, making for a murky image. The top view shows more of the same. Sharing with another user won’t be a great experience. But the screen’s curvature eliminates any visible issues for one person sitting on-center at three feet away.
Screen Uniformity

The G34WQCP sits mid-pack among other ultra-wide VA monitors in the uniformity test. My meter showed a slight brightness rise in the top left zone, but I could not see this in actual content. The rest of the screen measured extremely well. This is solid performance.

lttenso Hi... I was ready to Pull the trigger, but then i saw a new revison on gigabyte site, called g34wqcp rev. 2.0, with some diferences... 10bit display panel, mor nits of brigtness, a new stand... Etc... Does the 10 bit panel makes diference? The strange thing is, it maintain the same name with a complete diferent monitor... What do you think about this? Thank youReply -
cyrusfox My main complaint here is the VA panel, though less of a concern as it is a curved display and per your review, sounds like it is the best of this substandard display tech (I have a samsung VA ultrawide and the color shift from center to edge is horrendous, no curve though). Sadly many games I enjoy don't allow ultrawide configuration (SC2). As such I will stick with 16:9|16:10|4:3 configurations going forward.Reply
