780 Classified won't display HDMI.

post #1 of 11
Thread Starter 
Hey guys, I am trying to get my Classy to output both dual DVI (works fine) and HDMI. I have two 24" monitors working just fine through DVI-I and the DVI-D output of the GTX, but HDMI out into my AV amp and onto my TV will not play ball. I get no picture at all through my TV. Why is this? It used to have no problems with a single monitor then suddenly stopped working a few months ago. I didn't bother me massively as I got another monitor for multi tasking, but I really want to use a 3rd monitor (the TV) via HDMI to play videos etc so the GF can watch while I work.

Any ideas why it won't work? smile.gif

If you go direct from the card to the TV (bypass the AV Amp) Does it work?

I forgot to mention, I have tried without using my AV amp, going from HDMI out on the card to HDMI on my Samsung TV, to no avail. I still get a blank screen. =(

I'm still looking for a solution to my problem if anyone has any other ideas? I really can't be doing with an RMA as the card is now under water and it's my only card, loosing it for a week or more would be tragic! thumbsdownsmileyanim.gif

Do you have another monitor you can use to test HDMI or another cable to try? Also do you see the display at all in Screen Resolution settings? Example:

Yes, all Nvidia and display properties display the tv as a 3rd monitor, working just fine, although it's clearly not.

I tried using the 3 monitor vision thing in the Nvidia settings to see if it would somehow force the TV to work. It didn't.

Unfortunately I don't have any other TV that's small or easily accessible to bring to my study to test the HDMI output.

Oh and I've tried two HDMI cables, both of which work on my laptop through the TV and through the AV amp. Which is why I think the card is defective.

I know it is probably a slight possibility, but i had a client whose machine was detecting the display just fine but also displaying nothing. turned out to be the cable itself. Have a spare laying around to try?

I did a ninja edit to my last post, I have indeed tried two HDMI cables, both work on my laptop through the same TV and amp combo. smile.gif

well it was worth a shot. and at least that info is in the thread now smile.gif only other thing i can think of is reinstall the graphics driver and do a clean install to ensure it is all there.

you have labeled example HDMI 1 input = pc cos some tv's needed that i think, because your pc in most cases is designated VGA thumb.gif
