Thanks @ChuckPa. Appreciated.
After today’s update to QTS 4.5.3.1670 and the installation of nvidia 5.0.2 drivers, everything is back to normal. Works transcoding and displays all info about the GPU card, along with the percentage of GPU Utilization. You can safely install, especially since the new QTS includes security fixes.
GPU drivers 4.0.2 do not work with the new (today) upgrade from QTS.
Yep, just upgraded my TS-473 with a quadro. Back to enabling auto updates on the app store and all is working correctly 
Please confirm for me?
- P2xxx cards work
- GT-xxxx cards work
To finalize this test, would you be willing to install PMS 1.23.0 and test one final time?
Mine is on the latest 1.23 beta and working awesome 
Confirming 1.23.1.4528 has no transcoding issues on Quts Hero 4.5.3.1670, .NvKernelDriver 4.5.3.1670, Nvidia GPU Driver 4.0.2, Nvidia GTX-1650
Nvidia 5.0.2 Driver is not yet offered on QuTS hero
Thank you all.
Unless there are any objections,
I would like to mark this as resolved then close this and related threads?
Ok to close for me. Thanks for all your help @ChuckPa 
Same here .
Thanks for all your help
I confirm:
Qnap TS-873 + Nvidia Quadro P2200 on QTS 4.5.3.1670 and nvidia driver 5.0.2 all working.!
Thanks Chuck!
I do not thank qnap because it often makes these messes!
I confirm that after updating to PlexMediaServer-1.23.1.4528 *beta, everything is working.
