I'm dual booting Pop_OS and Windows 11 for now while l try things out. I went with Pop_OS for the NVIDIA drivers, since I have a NVIDIA card. Installation went smoothly, but setup is where things started to get a little weird.

I have 2 monitors, a main 360hz monitor and a secondary 165hz monitor. I seem to be able to have them both working at the same time in Windows 11 without issue, but in Pop_OS, setting the refresh rate to 360hz on the first monitor causes both displays to stop working properly. The 360hz monitor will stop displaying picture all-together, and the 165hz monitor will start flickering wildly. Turning off the second monitor brings the 360hz's image back, but then I'm down a monitor. Also, if I set the refresh rate to anything lower than 360hz, they'll both work. I'd like to still be able to use it at the native refresh rate, but I can't seem to find any other solutions or anyone else who seems to have had this same issue.

My second (slightly less annoying) issue is that I can't seem to use HDR in games. Is this normal, or is there something I can do to bring back support?

Also, if Pop_OS isn't the way to go, please let me know! I tried Nobara first, but immediately had issues with the displays locking up and flickering before I even got it installed.

I've just discovered that my monitor of the last 2 years (HP X27q) supports HDR 400. Not great, but an improvement over SDR nonetheless, I'd say. Only problem is, when I enable it, the monitor begins to emit a very high pitch whining noise. It's incredibly quiet, so quiet I didn't notice it for a few days. But now that I know it's there, it's definitely there and I can't go back to not hearing it. What in the world is going on with the HDR setting?

I might be completely misunderstanding the way Android Auto/CarPlay function. They're both essentially just screen projections from your phone to the in-car display, right?

Since my car only supports CarPlay, is there any way for me to "trick" it into thinking I have an iPhone plugged in and get it to allow my phone to display the Android Auto interface on the screen instead?

I've been having an issue with my Fold 4 recently where the cover screen will randomly stop recognizing touch input. The display still works fine, no flickering or odd artifacts, just the touch won't work.

It comes and goes. Sometimes it will work fine for weeks without issue, other times it will stop working for days on end, or even be in and out multiple times in a day. It seems to be software related and not hardware. Clearing the cache used to be a reliable fix, but at some point it stopped being a solution and now it's totally random whether it will help or not.

Restarting the phone or booting into Safe Mode has no effect. It always persists between restarts if the cache isn't cleared. To make things stranger, if I activate the rear camera selfie mode in the camera app, I am able to use the front touch screen in the camera app even when it isn't working otherwise. If I try to return to the launcher on the cover screen from the selfie camera with the phone still unfolded (so the internal display doesn't activate), touch input stops working again as soon as the camera app is closed.

I am completely stumped here. If it was an issue with an app that I installed, things should work fine in Safe Mode. If it was a hardware problem, I assume it wouldn't suddenly start working when using the cover screen for taking rear camera selfies and stop again immediately after leaving the camera. I can only guess that there's something wrong with a preinstalled app or whatever software Samsung wrote to control the multiple displays.

I'll take any suggestions at all if anyone has them...

Update for anyone else who might see this: I took the phone to BestBuy to get it repaired, but when they checked the IMEI, they told me it still had a few weeks of warranty left on it. So, after sending the phone off to Samsung for warranty repair, they just replaced it with a new one.
