KDE resolution issues with Nvidia drivers

I’ve searched the forum and can’t see anything exactly like this so I hope I’m not repeating something already documented.

I’ve just installed an MSI GT1030 card and the nvidia drivers.

I now have what seems to be two resolutions on the screen. On the desktop, application dashboard and in window title bars the resolution seems to be as expected (3840x2160) but when I hover over a window the mouse doubles in size and everything is too large. (fonts, menu items etc. Everything basically) Typing this my mouse cursor is at least double the size of my fonts.

The cursor is set to resolution dependant. If I force 24pts it doesn’t alter in size when over a window.

Is this a dpi issue or some sort of config problem?

This is a new install of 15.2KDE but I had an older graphics card if for a start.

I’m a bit lost with it. Used Opensuse for many many years, sometimes with nvidia and not had this before.

When I initially installed the card without nvidia’s driver everything was fine (apart from performance).

See if this helps…

Thank you for the reply.

I’ve seen the cursor point setting and yes, it does keep the cursor from zooming. My issue is that it isn’t just the cursor that is zoomed. It seems the entire window contents are at a lower resolution. So I’m basically loosing screen area to lower resolution, unnecessarily large windows and objects.

Hopefully this link to a photo works. You will see Arduino IDE appears much larger than pianoteq. The mouse zooms on Arduino but stays at 24pts over pianoteq.

Is that card up to that res my 1030 does not support 3840x2160 I think you would need a 1050 or above

https://www.msi.com/Graphics-Card/GeForce-GT-1030-2GH-LP-OC/Specification

HDMI (Supports 4K@60Hz as specified in HDMI 2.0b)
DisplayPort (v1.4a)

Ok mine is fan less from ASUS which may limit max res to 1920x1080 on heat considerations. Also my monitor is 1920x1080

Maybe check HDMI cable some cables do not support higher res. If using display port I guess it should work at high res

Yes the resolution is supported and the screen is definitely running at 3840 x 2160 60Hz.

However this https://www.websiteplanet.com/webtools/screenresolution/ says I’m using 2633 x 1481. :expressionless:

http://whatismyscreenresolution.net/ says similar.

I’m guessing it is checking what the browser is using and that would correspond with what it looks like in most applications. BUT not the background and some app’s.

Yes, that is my card.

Monitor is a Samsung lu32r590cwuxen, using HDMI cable that came with it.

To add to my previous points, the text and graphics in my window title bars are visibly crisper and smoother than the rest of the window space. Desktop icons are at the high resolution but desktop widgets aren’t.
