Hi people,

It's my first post here! :)

So at home, my computer has 2 displays: the PC monitor (main) and my tv. It always worked fine.

I bought a new card, a GTX 770 4Gb, to replace my old 560ti. I installed it today.

My computer seems to detect my TV, as do my TV seems to detect my computer, as before. But I can't get any picture nor sound on my TV.

Both of my screens are indeed connected in my graphic card.

TV is connected with HDMI, monitor with DVI.

Can somebody help me please?

Oh well... I did some more tests, the problem seems to be the cable itself. Tryied plugging it in the PS3 with no picture/sound too. I needed to use a mini (micro?) hdmi adapter with the 560Ti, I suppose it got corroded or something.

Thanks anyway! ^^
