I’m connecting to a virtual workstation using Nice DCV, and I’m unable to use resolutions higher than 2560x1600. What causes this limitation? Here’s the error in Xorg log file.
[ 11558.675] (--) NVIDIA(GPU-0): NVIDIA VGX (DFP-0): connected
[ 11558.675] (--) NVIDIA(GPU-0): NVIDIA VGX (DFP-0): External TMDS
[ 11558.675] (WW) NVIDIA(GPU-0): Mode (3840 x 2400) larger than per-head max resolution
[ 11558.675] (WW) NVIDIA(GPU-0): supported (2560 x 1600)
I read that some vGPU licenses are limited to 2560x1600. But according to nvidia-smi this is not a vGPU.
# nvidia-smi vgpu
No supported devices in vGPU mode
# nvidia-smi -q
