This cable was expensive, don’t want anything that’s only on Amazon.
Changed the refresh rate back to 160Hz, it did do the annoying flicker thing once, but that was right after changing it back.
Might be a while before I know. And if it happens again. Then maybe the monitor went bad. I don’t remember it happening in Fedora.
Guess I can try changing the desktop environment. If it comes back.
Or just enable this monitor on the other computer, and see if it does it on there too.
I had to disable AMS in KDE in Debian, thanks to a AMDGPU bug or KDE bug, who knows at this point.
Didn’t do the flicker thing since I changed refresh rate to 60Hz. The cable needs to do more bandwidth to support 4k @ 160 Hz.
And if disabling AMS is causing the annoying flicker, then there’s no point in using KDE. And in Gnome, I have to disable something else for it to work as well, because of the AMDGPU driver.
Pretty sure it did it in Gnome too, at least in VanillaOS. Know it does the freezing thing.
Don’t think FreeSync works with AMS disabled. All the info I read may be old though. Too lazy to enable FreeSync on monitor and in KDE. I can change the setting in KDE, so no idea if it works or not.
There’s one way to find out, turn it on on monitor and in KDE, then play a game, and wait for the FPS to go down. Or use one of those sync test things. Also, you may have to look at the monitor’s settings or wherever it shows the current refresh rate as well.
Update
Might not have needed a new cable. Was doing it, but not as often. Then I checked settings on monitor, and FreeSync was still on. Don’t click the middle of the button on this monitor, you have to click “right” to select/save it. If I click the center of the button it just exits the settings.
Well, it should be off now. But since it was doing it less, maybe this cable was worth around $40 anyways. Will be a while before I know if disabling FreeSync fixes the annoying flickering.
I might have been able to get a cable for under $20 on Amazon, but that brand isn’t even listed on the DisplayPort site with certified cables. And Amazon sucks anyways. They have bad working conditions. Other things aren’t great with them either. It’s possible prime is going away, or my mom ordered stuff not shipped by Amazon.
Wouldn’t be surprised, if prime is useless for shipping soon. They won’t announce it, and people will be pissed.
