There are reviews of this and other HDMI versions of mouse and keyboard emulation to enable hot buttons and switch mouse to side screen between devices, which is not good . Personally, I don't use this feature and prefer to use a USB 3.0 hub on the front. This works very well. Switching between devices is as smooth as you would expect. I have a gaming pc with a gsync monitor and graphics cards and everything works fine. I'm also an audiophile. I am using the PC audio output. My motherboard has a really nice built in DAC and it met my needs with an analog headphone amp output. This device adds a lot of noise to the audio output, so it's not that pleasant. In any case, I was thinking of an external high quality DAC that would solve the problem, but they really needed to test that. Adding a fair amount of shielding to the internal wiring should prevent this. This was to be expected though, so I'll just look into it and spend more money on a really good DAC.
