I got this to use my 36 inch ultra high definition monitor with my M1 Macbook Air and for that it works fine. A little lag compared to a laptop monitor but better than another no name brand. I tried it first. This one (highest rating on Revain) had issues with the monitor output where it flickered at times and was interlaced (horizontal lines) so I had to bring it back. It also had a terrible lag when moving the mouse pointer. Satechi is the recommended brand on Apple's website, so I had high hopes. It's not the exact model shown on Apple's website, but it has Ethernet built in, which is what I needed. You can find something better, but it probably costs more than double.
