Review on Dell U4320Q UltraSharp Business Warranty: 💻 Flicker-Free, LED, LCD, HD, IPS 4K Monitor by Christopher Wallace

Very good screen with good image quality, no dead pixels and excellent mechanics. The brightness of the display decreases significantly when changing the viewing angle. Because the screen is very large, the outermost parts of the screen are much dimmer than the center, even at a great distance from the table. Works great with Linux. Edit: I also pointed out the following issue earlier, but it was fixed by recent software updates. [Previously] Speakers don't work on Linux. The monitor doesn't even report the presence of a USB audio device when connected to a Linux computer via USB-C. When I called their support, Dell said they didn't support Linux, advised me to pay for a service contract if I wanted to discuss it further, and then just hung up on me.
