Probably not a cable issue. Barely used. Gold cables. Well seated.
Also, in my case, it's not entirely random. It happens only when there is some sort of video or streaming going on. In a forum or other website, or in email, etc., it never happens. Unless their references to "random" mean "during gaming," which is almost all streaming of one sort or another. I do have spare good cables, though, so I'll switch one out. The reason I also don't think it's a cable is that it only happened once I started using this TV as a monitor. Same cable as the previous monitor-monitor. The TV does have four (!!) HDMI ports, though, so I could try working my way through the other three to see if that changes something.
I keep the card's drivers updated with GeForce Experience, which alerts me any time there is a new driver available. So it's not an update issue. And the flickering does not change any of my settings. It just... well... goes black off and on for a few seconds, over and over again, sometimes with lengthier amounts of time of blackness. (I wouldn't really call it flickering--it goes black for a count of one or two or as much as 30, and then comes back.)
Will cycle through the other ports today and see if anything changes. And I'll dig out another HDMI cable, too, if only to narrow down the variables with easy changes like those. Thanks for these ideas, guys! And yes, @
ynwtf ... it makes me wanna figure this out too! It's like a mystery, and computer-mysteries are particularly annoying!
I upgraded the RAM to 24GB a few years ago for one of the Cyan games, probably Obduction. I recently played the new/upgraded version of Myst and it was so nice to be able to put it on max settings.
