Horrible Out of the Box

By Gamer Wifey
Rated 1 out of 5
Date: 2026-01-17

[This review was collected as part of a promotion.] This is NOT as advertised. Came out of the box with vertical banding and no way to resolve satisfactorily. Returned it thinking it was a singular issue. Got another one, SAME PROBLEM. If you're a gamer that is willing to spend a little more money for better quality, LOOK ELSEWHERE.

Misses the Mark

By GILLESPIE_1912
Rated 3 out of 5

The reason for the 3/5 stars is for a couple reasons. 1) They REMOVED the Pixel Sound technology that's in the 32GS95UE Model. This monitor instead comes with generic horrible monitor speakers. Now yes, most people use a headset but man the Pixel Sound technology is so amazing, and I don't know why it was removed. 2) The DP 2.1 spec is misleading as it is only UHBR 13.5 (54 Gbps). This means DSC is STILL needed in order to get the full 4k@240hz. Why not just have the full UHBR20 spec? Makes no sense. Do NOT buy this monitor if you already have the 32GS95UE, that should be an obvious one.
