thanks for your analysis and your time. Indeed I was also able to set the vgamem to 131072 without my Windows client crashing! That was good but the problem of the resolution to select remains. So I get a list like this:
but The resolution I want, 5120 x 1440 is not listed and auto resizing the VM only results in more black borders to the screen. So somehow I should inform the Red Hat QXL display controller to add that mode as a possiblity. In my Linux host I could do that by using Xrandr and add the resolution and the refresh rate. But in my Windows Client i do not see that option.
many thanks for your efforts. I really appreciate it because the actual user feedback for Linux newbee's like myself is rather low.

Hi Pavel,
sorry for my late reply. Thanks for your efforts and as matter of fact
I already increased the video memory in the XML file:
<video> <model type='qxl' ram='262144' vram='262144'
vgamem='65536' heads='1' primary='yes'/> <address type='pci'
domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/> </video> <video> <model type='qxl'
ram='65536' vram='65536' vgamem='16384' heads='1'/> <address
type='pci' domain='0x0000' bus='0x00' slot='0x09'
function='0x0'/> </video>
As you can see I have two virtual monitors in the configuration
file.The above configuration is the highest one which works. I tried
more Ram (My video card has 4GB of Ram) but than my Win 10 instance
just does not boot (black screen). The problem with this resolution (in
the configuration above) is that it is listed as 4K but it does not
allow the 5120 x 2560 resolution
kind regards,
I tried to replicate your setup and on my Fedora 32 setting vgamem to
131072 did the trick for me. You can keep the ram and vram at 262144 as
they don't affect the maximum resolution.
