Zorin 17.3 doesn't recognize monitor size correctly

The monitor is a LG 43" Class 4K UHD IPS LED (model 43UD79-B)

Graphics: Nvidia driver metapackge 580-open with a Geforce RTX5060 Ti 16gig

The computer thinks this an LG 27" even though it has the screen resolutions for a 4k screen. Desktop displays correctly, then I went to a game and, well, laughed. But this displays various problems the best:

I don't know if you can read those, but the graphics settings are actually recognizing 3840x2160. When the game plays it comes up in a screen in the middle of the desktop about the size of the Brave window off to the side.

Another game, Supraworld, seems to have an opposite problem. It's recognizing the desktop resolution, but all settings (text/pictures) just display HUGE (looks 500%+ size or more).

I was hoping it wouldn't be that big of a deal that Zorin thinks it's 27" monitor, but it would seem I need to correct it. Have searched the forums but not found, I don't think, the answer? In short, I don't know enough on what to look at to fix the problem and any help would be appreciated.

Thank you.

Some more info just in case:

Welcome to the Forum!

You are already on X11; that is good. And I see that You have Fractional Scaling active. Could You try it with disabled Fractional Scaling?

That would be a Point, too. You could try instead of the open Driver the non-open one.

Are secure boot and fast boot in your BIOS disabled?
If you use a Dualboot with Windows: Is fast startup disabled in the energy settings of Windows?

Appreciate the welcome :slight_smile:

I can't run the graphics card correctly on non-open. I would really like to and was hoping they had fixed whatever issue the 5060's are having when you recommended the switch. Just tried and it would seem not. It, Nvidia, act's like no card is installed on the non-open drivers.

Removed scaling. The games seem to scale correctly that I've tried so THANK YOU!

Zorin still thinks it's only a 27" monitor though. Hopefully, that doesn't really matter going forward.

Secure and fast are disabled. I'm not dual booting.


is this the driver version your using?

No, I'm on 580.95.05

But I couldn't tell you if the non-open version of the 580 is that driver. When I try to install, the Nvidia panel says there's no card. Prolly there's a terminal command that I don't know of to see? But with that driver everything acts like there's no card.

Zorin's screen says.. Actually let me just post a screen shot:

Okay, when it runs with this Driver keep it.

Good to hear.

My Monitor isn't detected rigth, too. The System only detects the right Manufacturer. But with the function, I don't have a Problem.
