After changing monitors, the desktop scaling is too large

We figured out that its the nvidia drivers, and i didnt recommend reinstall, but just to check if in the live usb he has the same issues…

You suggested him to install incompatible driver, and incompatible tools (and broke his system in the process?).

I didnt recommend wrong drivers, he installed them, and he had the same scalling issues with them … He didnt had any issues only when he run linux video drivers, on nvidia, nvidia 470, 390, and hybrid he had issues…

You can try to deny it but following your advices lead to breaking his system, that’s just what I’m pointing out. Try to be careful next time. I’m done here no need to continue the discussion, the OP has resigned anyway.

Well, manjaro is now reinstalled and using my old monitor everything is back to normal.

Overall, despite my system getting nuked, this has been a positive experience for me. I learned something very valuable; make sure to buy an AMD GPU before buying a new monitor.

The “new” 1080p monitor I tried to use was actually very old, over ten years old and did not cost me any money. I WAS going to buy an expensive new monitor and if this issue occurred after doing that I would be extremely gutted. Now I know to go AMD before doing that, and in this particular case reinstalling was not a big deal, my home partition is separate to root, and all I had to do was reinstall a few programs.

Omano, I already removed all that stuff from the TTY, leaving only the open source drivers which originally worked fine but for whatever reason still failed. I only reinstalled to fix the boot, I knew it wouldn’t solve the scaling issue, only changing back to my old monitor fixed that.

So even though all I needed to do was plug my old monitor back in to solve the problem I’m actually glad I learned what I did, so there’s no hard feelings brahma, thank you for trying to help.

Probably removing the Optimus tools left some system configs it created in modprobe or another system folder.

I will search if you want to try again, how to properly fix the issue, I recall another thread I replied to long time ago with similar issue. It was about the DPI you can see in inxi for the monitor. This is something configurable.

//EDIT: maybe this? Everything is big on proprietary graphics - #2 by omano or source thread Nvidia Driver - Large Objects - #4 by omano

I do think that could be the culprit, the dpi setting, as only certain things were large, things that had text in them.

My brother has taken the other monitor back we’ve reattached them to the arms so I can’t really be bothered to redo it all again right now. I’ll try it later and post the result. Thanks for digging that up.

Yep, that was it.

Nice, I’m glad it is fixed.
