Windows 10 resolution stuck at 800x600

[kenarsuleyman]

Hello, Here is my xml file below, host machine is ubuntu 22. In windows 10 I can not change resolution to anything. I tried to add SPICE display but it says qemu doesnt support spice, most likely I have to add a flag during compile to add spice support. My question is if i compile using spice support and spice display, will it break undetection tweaks, or what else can i do to increase resolution.
