You also have a "2019 5k iMac"? Because that is very important in this
context.

> Please help me.

I can't, my "video driver chops" are too short for that, but perhaps
I have a rough idea what people able to help you need from you.

At least, try to describe your hardware somewhat. Possibly there is
some (non free) firmware missing for your GPU, but to find out
which, and where to get it, people here need to know more.

Some more details out of your Xorg.*.log would also be very helpful.

Help us to help you :)

Are you comfortable with a Linux console? Can you switch into one
(CTRL-ALT-F1, for example) and enter commands there? This would
also ease things.

Cheers

I would suggest installing Debian 11 - just released - for two reasons:

1.) The software is significantly newer - it may be that the video card was
initally released after the release of Debian Buster - so not so well 
supported. It also uses a more modern kernel - 5.10.

2.) If you use the unofficial media image including the non-free firmware 

https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/current/amd64/iso-cd/firmware-11.0.0-amd64-netinst.iso

the firmware detection and installation for firmware for video cards has
been improved significantly.

I appreciate that won't help you with Debian 10.6 but Debian 10.10 would
not help much either.

With every good wish,

Andy Cater
