I'm having problems a lot of times connecting my monitors with the HDMI port. Sometimes the external monitor connected by HDMI works sometimes don't work.
The PC recognizes the monitor but don't send any image. I'm on windows 11. I have tried with both my external monitors and with more than 5 HDMI cables and the problems occur with both monitors and all the cables. Sometimes I shut down the computer and then starts working. Other times no. I have spent 3 days without external monitor from HDMI, this morning was not working and now is working. The monitors connected to external dock station are working fine for now!
