I have a Media Center setup with a Hauppauge HVR-3000 tuner, nVidia 8800GTX graphics card.
If I plug the Media Center into any computer monitor I can watch DVB-T Freeview no problems. If I plug it into the LCD TV via VGA it plays also no problems, but cannot set 1080 resoloution.
If I plug it in via HDMI to the LCD TV it does 1080 resoloution no problem, screen looks seriously sexy awesome, BUT....
IMMEDIATLEY after I plug in the HDMI to the TV and the Media Center (DVI-HDMI adapter then HDMI to HDMI cable) the Hauppauge tuner totally looses signal says it has no signal and of course displays no picture what so ever, IMMEDIATLEY after I unplug the HDMI, the signal comes back... wtf
Also if I have the media center turned on and plugged in via HDMI, then unplug the aerial and plug it in to the TV and use the TV's built in DVB-T Tuner it gets no signal also, but as soon as I turn off the media center or unplug the HDMI the signal comes back on the TV and I can watch it no problem.
So it works under VGA but the HDMI cord somehow makes major interference that causes both the TV and the media center to not be able to get any TV signal what so ever...
Ideas for me please?!?!
