Jetson AGX Xavier H.265 Decoder spec

Hi,
I am planning to develop a board that plays 4k 120hz video.
The Jetson AGX Xavier(16GB) H.265 decoder specification indicates that it supports up to 8k 30hz.
Is the decoder level 6 correct?
I want to check if I can display 4K 120hz video on DP1.4 through Jetson AGX Xavier.
Thanks

Hi,
4Kp120 is not supported on Xavier. There are two NVDEC hardware engine and each can do 4Kp60. The supported case is multi-instance 4Kp60 decoding. Single 4Kp120 is not supported. For more information, please refer to module data sheet:
