A:Answer I've used it as a tv replacement for several days hooked into the receiver so I have sound (no speakers on the monitor itself). Works well. I cannot comment on Roku, but I have a desktop plugged into my AVR, and can watch DirecTV, stream on my PC, and even play games on PS4 all hooked into the AVR. I never expected to use it this way, but when I had to, it worked.
