Back when vGPU 10.0 was released, NVIDIA switched from a “Fixed Resolution” to “Pixel based Resolution”. They did this due to the large amount of non-standard panels that are becoming increasingly popular, such as the Super Ultra-Wide variants. I myself use a Dell U4919DW which has a resolution of 5120 x 1440. At first glance, the resolution looks quite high, however once you calculate the total amount of pixels, it’s not very high and is actually less than a single 4K panel. The problem is that because it’s a non-standard resolution, the previous versions of vGPU drivers wouldn’t support it, and when trying to run Virtual Machines in full screen, I’d have a full screen vertical display (1440), but with the black “bookend” on both ends of the screen as the vGPU driver had a maximum horizontal resolution of 4096 (and my monitor is 5120) so wouldn’t accept the resolution, even though that same version of vGPU driver would support multiple 4K monitors (up to 4) which as said, with even just 1 of those being a higher total pixel count than my U4919DW. The logical option for NVIDIA was to move to a far more flexible configuration, which is where we are today.
The reason for asking how many monitors you have and the resolution of them, is that with the 1Q profiles you can support up to 17694720 pixels. A few examples of common resolution options are available here: https://docs.nvidia.com/grid/10.0/grid-vgpu-user-guide/index.html#vgpu-types-tesla-m10 so you can calculate what you’ll be able to run.
