Just got Windows 11 today, my second monitor is connected via HDMI and was working. I tested enabling HDR and my second display stopped working. The external second display HDMI monitor is HDR capable. Display settings shows its not active but it detects monitor 2 is connected and detects its an LG but it won't activate. I can't disable HDR that broke it. Now only my main Lenovo X1 display works.

HDMI Port Stopped Working

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?

 

Second monitor not working with HDMI

Hi,

I have a AOC monitor hp Pavillion laptop and while trying to connect to the monitor using a HDMI cord, nothing is displayed. Comes up with a No Signal info. I have tried multiple cords : HDMI - HDMI, HDMI - DVI , HDMI - VGA, nothing works. The monitor is
not detected. I have another laptop on Windows 7 and and if I try to connect directly with VGA - VGA, it works, but does not work with HDMI from the same laptop. Basically, it does not work with HDMI at all.

I have updated the latest graphics card, both nVidia and Intel, but no progress.

If I use the same laptop and connect to my hd tv using the same cord it works, but does not work with my monitor. The monitor model is AOC e2450swh. It has support for HDMI. Even if I try to use a HDMI to VGA cord, still it does not display anything.

Any suggestions would be really helpful.

Thanks

 

My HDMI connection to my second monitor no longer works

The problem has returned--sort of. Here is the sequence of steps I followed:

1. No display on my second monitor, despite the fact that the HDMI cable was connecting my computer to the monitor.

2. Tried changing the *Start-P settings repeatedly. Nothing. When I set the connection to "extend," my computer clearly thinks that there is a second monitor (all the Windows icons go there--as I have it set to my #1 display), but it is completely dark.

3. Tried multiple restarts. Nothing.

4. Tried connecting it to my older laptop as described above. Worked perfectly.

5. Plugged it back into my current laptop. Works just fine now.

So clearly it's some sort of software or setting issue. Can anyone tell me how to fix this if it comes up again without having to resort to using my old laptop, in case I don't have it around?
