Does Downsampling "hurt" the display?

I started using, couple weeks ago, Downsampling to 2K on my 32' LED 1080p display through Nvidia Control Panel, but today at morning my TV had little squares of pixels totally out of color, going from green to pink depending on the background color.
Hopefully a full factory reset solved the problem. (Don't know if it's going to last)

My question is:

Does Downsampling "hurt" the display?
May the problem I had be caused by it?

Thank you.

No, downsampling does not hurt displays. It just takes the input and runs some processing with it and displays it like any other input. Usually downsampling with PC's is handled by the GPU anyways, which again, is just a computational process that it is designed to accomplish.

Your GPU may be overheating though.

EDIT: I suppose I could be wrong. I've never heard of such a problem, however.

Downsampling is a method to get cheap AA. You set your GPU to 2560x1440p and send it to a 1080p display. The scaling back down to 1080p is a very similar result as to what OGSSAA does.

Yes,

I always check the GPU temp. and on full load it has never gone beyond 70ºC.
Idle it runs at 38ºC.

It's an GTX760-DC2OC.

The problem on my TV was happening watching normal channels, or on it's own setup panel too, not only desktop.

I've never heard of downsampling causing an issue, but when using non supported resolutions, I've always seen warnings of possible hardware failure. I'd test the cable first, but if it works without the PC hooked up, then clearly it is with the display and not the PC.
