External HP Monitor shows for 10 seconds then turns blue...

I have an external HP Monitor I connect to my 2020 MacBook through HDMI to USB C, but every time I connect them it shows the display for 5 seconds and then just gets blue.

I tried restarting with a reset of the SMC/PRAM but it hasn't helped...

Try booting to Safe Mode. That boot up takes minutes and clears caches and other things that may resolve your problem.

Does it work in Safe Mode?

A lot of times just boot to Safe Mode followed by normal boot resolves problems.


Does the monitor work on another device with sae monitor input?
