Samsung DeX - poor quality when connected to PC

[Nord]

Greetings,

as the title suggests I have a problem with Samsung DeX or rather it's picture quality, it just looks… well, like garbage when connected to my PC.
Here's an example: https://i.imgur.com/jbesqBv.jpg
It's especially noticeable on the “gallerie” and “playstore” buttons on the left upper corner or the Chrome icon in the middle bottom. It's weird because some icons, text and pictures look “ok” while others look like garbage.

I’m using a Galaxy S20 FE
I tested it on two Win10 PC’s. A desktop with an Nvidia GPU and a laptop with an Intel IGPU (on the integrated laptop monitor ofc).
I tried the original “charging cable” that came with the phone, I tried aftermarket 5Gbps anker cables and with a bluetooth to PC connection.
Phone is connected to my Wifi 5G network - which has a theoretical throughput of 1.3Gbps - and I also tested with both the connected PC being either directly on a CAT6 cable to my router or in the same 5G Wifi.
Resizing or fullscreening the DeX application window on Windows10 itself does nothing either.
 

The only use case I got for DeX is to connect the phone to my PC, so that I can take notes or answer messages directly from there while waiting for matchmaking in those spicy video games the kids like to play.

So apart from buying that, for me, utterly useless “dock” for DeX, is there a solution to fix or at least improve this? I mean a TeamViewer connection to the phone looks like 10x better than DeX...

Thanks!

 

Ps. The only relevant results I could find on this boil down to “TrY cHaNgInG yOuR mOnItOr ReSoLuTiOn”. Which, given that I’m using good old 1080p 16:9 monitors and resizing the window does nothing either, is about the same level of expertise as trying to refill one's car blinker fluid.

Just looks like the image compression level they chose to use is garbage, unless there's a setting for that it's how it's going to be... Shouldn't prevent taking notes or writing messages though.
