So, I have a problem (well, at least one problem): on occasion, sometimes every couple minutes or every few days, my 4K 60hz TV that I use as a computer monitor displays static. Higher resolution and color than you'd get from a 1980's or earlier TV tuned to a UHF channel, but you'd still call it "static." To temporarily get rid of the problem, you need to unplug and re-plug the HDMI cable on either the TV or video card.
My computer troubleshooting has always gone from easiest and least expensive repair to difficult and most expensive.
* Checked HDMI video cables. Even swapped with a new cable that I know works. Nope.
* Checked using different HDMI ports on my TV. Nope.
* I've got about a year-ish old "2K" monitor (2560 x 1440) that also has an HDMI input. It's also a 175hz monitor. The video card only supports up to 144hz. Worky. Hmmm.
* Set my 4K TV to 2K @ 60hz resolution. Seems to work OK.
* Tried a different video card, just because I have one. Works fine ... at 4K 30hz. The card doesn't support anything higher. Hmmm.
* Removed the test video card and popped in my old one. Set to 4K 30hz. Seems to work.
* Just for fun, I tried the original video card in a different PCIe slot at 4K 60hz. Nope.
* Well, I'm going to need a newer video card, anyway, so I bought one. So, 4K @ 60hz ... nope.
So problem is either the computer, itself, or the TV. One of them is disliking 4K @ 60hz. 30hz makes my eyes bleed after about an hour. The TV is still less costly than the computer, but not by much. I'll also have to wait several months to have enough $ to pay for either. I was hoping on not replacing either until Windows 10 is end-of-life in 2025.
