Screen tearing only one server

[Jan-Willem]

Hi,

We have a setup with two ESX servers running Horizon clients, server one runs fine no issues but on the second server users are running into issues.  Some days not all users get screen tearing, artifects and other stuf. When i move the clients between te servers the problem dissapears. The problem won't resolve itself over time.

But servers are running with a two T4 Nivdia cards, with ECC enabled with Horizon 7, esx 6.7.
The strange part is that server one witch runs fine is showing less video memory than the server that has the problems (server2). 

I am thinking this issues is related to the videocard, as everything else is the same. 

Did someone encouter this issue before ? 

Thank you .

Hi @Jan-Willem,

Is the same NVIDIA GPU VIB installed on both ESXi hosts?

[Jan-Willem]

Yes both servers have the same VIB:

server 1
NVIDIA-VMware_ESXi_7.0_Host_Driver 440.87-1OEM.700.0.0.15525992 NVIDIA VMwareAccepted

server 2
NVIDIA-VMware_ESXi_7.0_Host_Driver 440.87-1OEM.700.0.0.15525992 NVIDIA VMwareAccepted

What i found is that the working server is running VMware esxi 7.0.0 and server 2 is running VMware esxi 7.0.3 is there a known issue with this ?

First of all, both hosts should be running on the same version of ESXi. Besides that, your NVIDIA 440.87 is on a not supported version and was EOL December 2020 > https://docs.nvidia.com/grid/index.html

vGPU 13.x offers support for ESXi 7.0 Update 2 and later > https://docs.nvidia.com/grid/13.0/product-support-matrix/index.html#abstract__vmware-vsphere
