Review on LG 32UL750-W 32-Inch 4K Monitor Display - Silver, 3840x2160P, High Dynamic Range, Anti-Glare Screen by Adam Maciel

The screen goes black/black several times a day. In this case, the built-in speakers are also deactivated. The problem lasts a few seconds. At first I thought it might be my computer, but then I found that I have the same problem when using my Mac. It's very frustrating to be in the middle of a meeting and have these snippets. A quick search of online forums shows that many other people are having this problem. As far as I know none of them found a solution. It's time to claim the guarantee.
