Windows 10: Cannot connect my windows laptop to a monitor using an HDMI cable

Hi,I have an HP Pavilion Gaming Laptop 17-cd1006np 2L1T6EA running on windows 11.I cannot connect my laptop to a second monitor through HDMI.

Laptop display and monitor will not wake when HDMI cable plugged into laptop.

I have a laptop. Lenovo ideapad FLEX 4-1480 Signature Edition.

The laptop has a display, and the laptop is connected to a monitor via an HDMI cable.

Sleep mode is disabled.

Screen timeout is enabled.

I lock the computer. The laptop display and monitor both eventually deactivate.

I move the mouse and press keys to wake the monitor. Nothing happens on either the laptop display or the monitor.

If the HDMI cable is not plugged into the laptop, the laptop display will wake as intended. The problem happens only when the HDMI cable is plugged into the laptop.

I have to remove the HDMI cable from the laptop, wait a few seconds, reinsert it, then the laptop display and monitor will wake. Again, the laptop display will wake just fine when the HDMI cable is not plugged in.

 

Cannot connect HDMI Monitor with laptop

Hi!

Thanks so much for your response, Carmack!

I figure out the issue and want to share it with others. I used a USB - HDMI adapter and HDMI - HDMI cable to connect my laptop with the monitor. I removed the adapter driver (my laptop's functions are irregular when the driver exists). Now, I use a miniDP - DP cable to connect to the monitor. The problem is solved.
