I have a home theatre PC which I was planning on using as the input for the Xbox one, however whenever I plug it in, it doesn't seem to work right.
For instance the screen will load (eventually) but have quite a few artefacts on and if I try to do something e.g. move the mouse, the whole screen will freeze sometimes for a long while other times it doesn't do anything until I unplug and re-insert the HDMI... rinse and repeat. Inhale tried multiple resolutions all have failed. Even my CEC adapter is being recognised (and yes I have tried it without it) but the picture is just completely non responsive.
I'm using a HDMI socket on my pc, and it uses an AMD Fusion APU for the graphics. The pc works fine if I plug it straight into my TV.
My PS3 works OK as the HDMI in, but I don't really want that going into the input due to the slight lag it would introduce. This isn't an issue for general media.
