The pixel format output from HDMI of JetsonTX1

I have a question about BSP of JetsonTX1. What is the pixel format output from HDMI of JetsonTX1?
ex.) RGB,YUV

Hi,
Please refer to this topic which may help.
https://devtalk.nvidia.com/default/topic/988643/how-to-modify-the-jetson-tx1-hdmi-output-format-from-rgb-to-yu#

“Tegra_X1_TRM_DP07225001_v1.2p.pdf” has the following description, but will the output of HDMI be RGB 444?

24.3.16 Output RGB-to-YUV 444 CSC

This allows for support of the following output formats to HDMI:
• RGB [0, 255]
• RGB [16, 235]
• BT.601 YCbCr 4: 4: 4 (converted from RGB [16, 235])
• BT.709 YCbCr 4: 4: 4 (converted from RGB [16, 235])

27.4 HDMI

• YUV 444 output (BT.601 and BT.709 formats)

If the output format is RGB444, how is the RGBA8888 data of the frame buffer converted to RGB444?
Is it impossible to directly output RGBA8888 from HDMI?

Hi kmatsuda,

Please refer to the chapter “Display interfaces:HDMI and Displayport”. It implies the pixel format HDMI supports (24bit RGB and 24bit YUV). However, YUV mode is disable on L4T.

RGB444 imples no chroma subsampling.
