Hi Uri
Thanks for your reply and your notes is right only that 
Vw is wrong spell. I means vm for virtual machine.
 I have deploy the streaming agent and I will try h264.
4k vdieo is one of requirements of our project.
So pls help us with this.

Hi :
I am a phd student of Xian Jiaotong university in China.

We have a project to accomplish a remote-desk solution with Nvidia vgpu.
We use spice latest version  and have a bad 4K display quality.
Our environment is like:
1.T4 card with inspure server in nvidia support list
NVIDIA Tesla T4  GPU card



2.redhat 8.2 enterprise  with kvm qemu
 

3.vgpu software package is 13.x
NVIDIA driver + tools (GRID)

 
4.vw flavor is 8u 16G. with 40 storage.   vgpu license is vpc ,and vgpu is B-2b.
"vw" == Virtual Workstation

B-2b is the vGPU type? meaning T4-2B ?
Does it help if you configure it with T4-2Q (may require a different license)?


Only a single Display, right ?


Are you running spice-streaming-agent on the guest ?
Try to stream with H264, if you do not already do it
(may require paying fees for using H264).



Is 4k resolution a requirement? If not, try with e.g. 2k.



Hope that helps,
    Uri


 
And our issue is attached in appendix.
Please give us some help to solve this.


best wishs;
leo zhang
