Review Summary

Rated 3 out of 5

Misses the Mark

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.

Great monitor

At first I was concerned with the red and green pixely lines and the purple outline on my screen but this went away quickly. It's a nice display and I am happy with my purchase even though less than a week after I bought it it dropped $150 more on a sale.. it comes with the 2.1 hdmi and display port cable, along with a nice heavy duty USB c cable for I believe the USB 4 technology.
