Is it possible when using a long video cable for a TV to ruin a card's video interface?
Can the card get to a point it is struggling sending a signal and fail even though it has been working fine for a few days?
Two DVI ports on my card stopped working at some time when connected via a DVI-HDMI adapter and a 15m HDMI cable.
The graphics card is GIGABYTE GTX 970 G1 GAMING.

This question is related to the one I asked before here:

As said no damage but the TV may not be able to receive the signal. The weaker the signal the less likely the TV will be able to 'hear' it. I have a 10m HDMI cable, I have found one TV which wont display a picture when using that cable and my laptop, all other TV's work ok and the TV with the problem is ok on shorter cables. Its like the one TV is a little hard of hearing and doesn't like the quieter signal.
