(I have checked the Flex cable connection multiple times.)

Radxa 10FHD only supports mipi 4lan, but the mipi on ROCK 4SE is 2lane, so only 8hd and 10hd can be used on ROCK 4SE,and you can see overlay not support 10FHD.

Hi Alvin,

Thanks for your quick response. I didn’t realize that the 10HD is not 10FHD.

However, 4B+ is listed as supported on your official reseller’s website, which is why we bought it.

Sorry,maybe ALLNET made a mistake,just ROCK 4PLUS support 10FHD on ROCK4 family.

Hi Alvin,

Apologies for any confusion. I am indeed trying to use the 10FHD monitor with the Rock 4B+ (so Rock 4 B Plus), as mentioned in my previous message and shown in the picture.

In your previous response, you mentioned the Rock 4SE. I assumed that “Rock 4 B Plus” was equivalent to “Rock 4 Second Edition”.

Could you please clarify the compatibility between the 10FHD monitor and the Rock 4B+?
Because “ROCK 4PLUS” product doesn’t exists.

Thank you for your assistance.

Sorry, I wrote it wrong. It should be ROCK 4C PLUS or ROCK4C+. Rock 4B+ not support 10FHD .
