Hello guys just make a new build and after a week, i have a problem in my display .i have sapphire 6870hd and the problem is that I have no display in hdmi port ,i check the display in dvi port it display correctly but in hdmi port it does not show anything.i have worked in hdmi port since 7 days and there was no problem but today there is no display. Please help and i also try the different hdmi cable and there is no display.
Dude i have no settings changed and I properly turn off the computer and when I wake up and just start the pc it's shows no display. I have hdmi confections always. I just plug in the dvi cable to check that it is graphic problem or not.
If you could post your mobo model #, I'll be able to look into this issue a lot more.
I just realized your using a TV for display. Dumb question, but could it be the input selection on the TV changing itself?
