Any monitor with the appropriate input port to match your video output port on your PC. I hooked mine up to a 75" 4K Flat Screen, and it worked great. I normally run it on three (3) 27" high-end 4k monitors showing one large display. Resolution is 5760x1080 and It looks real good. RFX however will not run on 3 monitors under AMD Eye-Finity protocol...
