Shortly before FYI: I have connected 3 monitors at the PC and wanted to join the main screen also to the TV.
1) The PC does not recognize the resolution of screens.
Unfortunately, all wallpapers are nurnoch shown on half-size to demAnschluss because the PC says, you could connect a 420p screen. One can not change the resolution of screens. Which leads me to ...
2) the image quality
and not too weak. Had it been only a slight effect I had no problems, but on both screens, the screen looks much less sharply, there is a strong smearing and color are under or over-emphasized. You can still see everything, but I have bought me no 1080p television.
3) The sound is not split
People who live in a different room, is the sound unfortunately have nothing. The fact is not split and must practice rthe sound card of the PC running.
