I am not running any special video card or Vgpu this is just a normal setup
It just started to happen in 7.20
Did you adequately increase the size of the vRAM to account for the higher resolution?
Yes; we have tired 48mb or 128mb of ram
Auto Select and Tired our own same issue still
I figured out the problem and solution for myself
Biggest problem is I'm using the old school VSphere Client and not the Web based client
In the Web based client you can set you video adapter; the default changes on the VSphere Client don't have the options you want.
I hope this help others who might run into this issue.
Here is my Windows 10 VM
Make sure to set the Video Card with the displays and the Resolution Size in the Calculator
Now take a snapshot and recompose it will fix the image issue
