Windows 10 VM "native" resolution stucked to 800x600 on VNC mode


Recommended Posts

HI guys,


I hope somebody can help me. I´ve searched already the forum and net but could not find anything that helps.


I am running a Windows 10 vm on VNC graphics. There is no dedicated graphics and also not needed.


Problem is that I cannot change the resolution from 800x600 to anything else. It is greyed out in Windows. RDP is working fine with any resolution. But if I go with Team Viewer it is connecting to the native desktop and then I see only 800x600 again which is aboluteley not workable.


I changed alsready the VNC graphic driver from QXL to cirrus. No change. VMGA is greyed out on the settings so I can´t test that.



I also tried to install the QXL driver from virtIO.iso but the driver is not win10 capable. :(



I need this urgently. please help





I found the solution :D


Just found out that on fedoraproject is a much newer virtio iso taht contains the qxldod driver. this is w10 ready and works. Resolution is now changable and works great.


maybe this helps somebody else as well.

Hi Donativo,


I just had the same problem, and it can be fixed by installing the vitrIO driver for the vnc GPU. 


Go to "manage devices" and right click on your GPU -> update driver -> select your virtIO drive -> click OK. 

I had mine installed in 5 sec. and it's working like a charm now. I found the solution here.


I know it's bit late since the topic was created, but thought others might have the same issues I did. :)
