Monitors my crypto rigs flawlessly. I tried other options but this one has been the best so far. I needed something with adjustable auto-scanning and this did the trick. I had a question on how to turn the beep off and the Seller responded promptly (scroll lock, scroll lock, F11).

Works well for 3840x2160@60Hz 4:4:4. Overall is an outstanding product, and I use it to get perfect image 4:4:4 3840x2160@60Hz on my Samsung 40" TV. For 10-bit color, I can only get 30Hz, but my TV has the limitation, so I am not sure if the problem is with this unit... The box works fine with Linux, Windows, and Mac all mixed up. Since hitting twice scroll lock followed by the 1,2,3,4 works flawlessly, I rarely use the "Select" button or the remote that came with it.
