To resolve connection issues with some niche monitorsThe main symptom is that the system automatically switches to 8K mode, causing a black screen because the monitor itself does not support 8K resolution.If you encounter this problem, upgrade the N88SX_HDMI program.Do NOT upgrade the program if you do not have similar issues, as it will result in the loss of certain NVR functions.

Important note:

1）After upgrading this program, do not perform any further system upgrades.

2）This program is a neutral program. Therefore, if you perform a reset after upgrading this program, please remember the IPC password in advance.
