40" T.V connected via HDMI to GTX 690 (using dvi to HDMI adapter)

This T.V is new and has only been connected to the PC for a week.
Recently the T.V started to flicker slightly and getting thin discolored lines randomly across the screen.
A few times the screen has gone black before reconnecting and displaying the image again.

I'v connected to HDMI 2 (was using HDMI 1) and the issue seems to have gone away, but I wonder if the same could happen to the HDMI 2 connection? (It has been less than an hour connected to HDMI 2)

Would the GTX 690 cause such an issue and possibly damage the T.V?
Or is this a sign of a defect with the T.V?

Any settings I should look at in Windows 7? or the Nvidia control panel?

Suggestions appreciated!

Thanks!
