A super simple to use, I use it to connect two screens of different size spaced 10m (HDMI video card output to) screens 22 "and 42", with a resolution of (1360 * 768), Maximum for 22 "and more than sufficient on the 42" hd movie distribution and 3D sound with DD fluid and sharp picture ....
Also testing for the HD broadcast TV signal box to my two screens, works great despite the different size of my screen ... Ideal to see ADSL TV programs, or other decoders, on multiple screens without having to subscribe options Mufti-screens;)
Highly recommended !!!!
