I’ve got a desktop, and I use a Samsung TV and now it’s suddenly refusing to display properly at 1366x768 at 60hz so I’ve had to adjust it to 1920x1080i at 30hz.

When I try to adjust it back to its original settings, the screen is divided into three sections with all the colours inverted and the screens overlapping each other. It’s not my graphics card which is an NDVIDIA 1060 3gb, but I think it’s to do with the original graphics which come with the computer. If so, how can I adjust it back?

If as you suspect the onboard graphic is the culprit, why don’t you plug the TV into the graphic card and look what happens? This is the first thing I’d check.

If this works, I’d check the drivers for the onboard graphics and update them if necessary.
