The solution is for reading medical radiology image that need 10bit hardware output technology and running on top of VDI and at least 3K resolution, currently we are using ATI FirePro works great but we need to move to VDI solution.
Does NVIDIA GRID support this solution? Thanks!
The GRID cards are capable of delivering this, but are reliant on the remoting technologies to expose the 10bit greyscale option which will appear in the Control Panel when a 10Bit greyscale monitor is detected.
If the remoting protocol cannot present a compatible display the option is not presented, regardless of what is physically at the endpoint.

You may want to contact them to raise your need or explore other vendors such as NICE/Teradici/Mechdyne. I'm not myself aware of a full VDI solution that implements 10-bit colour.
10-bit colour (40-bit over the 4 channels) vs. 32-bit VDI increases the data volumes greatly, add in 3K and the fact medical images are usually very large and it is a huge challenge on bandwidth to maintain frame rates. This maybe why adoption by the mainstream VDI vendors hasn't happened.

The NVidia GRID driver should probably "emulate" DisplayPort output (NV_MONITOR_CONN_TYPE_DP) to resolve this problem.
The NVidia Capture SDK should support 10bit capture format like in NVidia Video Codec SDK input (NV_ENC_BUFFER_FORMAT_YUV420_10BIT, NV_ENC_BUFFER_FORMAT_YUV444_10BIT, NV_ENC_BUFFER_FORMAT_ARGB10 or NV_ENC_BUFFER_FORMAT_ABGR10 (packed in 32bit A2R10G10B10 or A2B10G10R10)) to resolve this problem.
There are also "thin" candidates for the other end of encoded VDI video stream to display h265/10bit/4:2:0/4K/60FPS (HEVC Main 10) - like OdroidC2 for £40 (£48), Asus Tinker Board for £46 (£55) or Rock64 $25 (but not RaspberryPI :-( for £28 (£34)). But formats like h265/4:4:4 or h265/LOSSLESS (also supported by Pascal card encoder) should be more useful for medical purposes.
- NVFBC_TOXXX_ARGB10 (NvFBCToSys, NvFBCToDx9Vid and NvFBCToCuda)
- HDR - bHDRRequest in NVFBC_ToXXX_SETUP_PARAMS
NvAPI_GPU_SetEDID() virtual vGPU output is set to valid HDR/HLG/DolbyVision EDID (from LG TV).
NvAPI_Disp_GetHdrCapabilities() returns NVAPI_OK but zero data.
NvAPI_Disp_ColorControl() returns NVAPI_ERROR (there is no documentation how it works).
Output is still NV_MONITOR_CONN_TYPE_DVI.
