Why is RDP low color depth?

Question

RDP

Hello everyone, when connecting to a computer via RDP with a configured resolution from 800x600 to 1920x1080, for some reason the color depth is low, but if you set the connection resolution to 640x480, then there are no problems. I tried to change the depth color settings to all available (15, 16, 24, 32 bits) nothing changes, if I connect to another computer, everything is fine. Windows 10 is installed on the computers on the one from which I connect Home, on another Pro. All updates are installed, the computers are on the same network, the connection quality is excellent, the connection is via UDP. I tried to google and found that you can change the settings in the GP, changed nothing has changed.

Answer 1

Update video drivers on both sides

Answer 2

What an exotic case.
Something is wrong on the machine you are connecting to.
This is not a driver for the video card, since when connecting to a non-server (rdpX protocol) no video card is used, one could assume that something is wrong with the machine from which you are connecting, but you claim that to other machines it connects correctly.
Do not be lazy, connect to this problematic machine not from windows but from linux (livecd in a virtual machine for example) using remina there is an opportunity to change the protocol version, sort it out, maybe your machine forces you to connect with some specific one and it's buggy.
Now for the specifics - in the connection settings in the mstsc program, try changing the channel width parameters - the interaction tab (they determine the rest, including the color bit depth).

Answer 3

Faced the same problem, the video card is also AMD
Check the settings of the video card of the remote PC there is an item "10 bit pixel format" - you need to turn it off. Everything worked right away (after a reboot).
