multiple monitors - Second Display not detected in Windows 11 - Super User

Ensured that both the graphics card drivers and Windows 11 are up to date. Checked the display settings in Windows to see if the second monitor is recognized, but it's not listed. Tested the second display on another computer, and it works without any issues, ruling out a hardware problem with the display itself. Tried different output ports on the graphics card (HDMI, DisplayPort) to connect the second display.

r/WindowsHelp on Reddit: Second monitor HDMI not working after updating laptop to Windows 11

November 3, 2024 -

UPDATE: Solved! Check the comments for the solution that worked for me

Hey all,

I've been trying to connect my laptop (ASUS TUF Gaming FX505DT-BQ613T) to either my second monitor or my tv screen through HDMI. This has worked perfectly fine in the past, but after I updated it to windows 11, it stopped working. I've tested both the cables and the screens with other devices, and they work, so I don't think they're the problem.

When I plug in the laptop, there does appear to be something happening - at the very least, the monitor lighting up a bit, but then saying 'no signal' anyway. Similarly, when I unplug the cable, the laptop screen turns black for a second. It seems like there's not really any signal being sent through the cable. If I go to the multiple displays settings and click 'detect', it says 'we didn't find another display'.

I've tried a restart, and I've tried updating the display adapter drivers, but windows said that they were already up to date. I've also tried changing the display frequency to either 60 or 40 Hz, but no difference.

I'm not sure what to do next - I'd prefer not to mess with reinstalling the entirety of windows 11. Does anyone have an idea? Please let me know if you need any more info from me. Thanks!

r/techsupport on Reddit: Windows 11, Second monitor can't be detected, even when both monitors work independently.

February 15, 2023 -

My husband just built me a new PC and got Windows 11 downloaded on it. But it doesn't seem to be working with my dual monitor setup. I have two Lenovo monitors, one is connected via HDMI cable, the other connected via DVI cable. When just the HDMI monitor is connected, it works fine. When just the DVI monitor is connected, it works fine. But when I have both connected, only the DVI monitor works and the HDMI monitor can't be detected. I have a DVI port in the back of the computer that connects to the graphics card, and one that connect to the motherboard. Both ports work fine for displaying the DVI monitor, but it's just getting the HDMI monitor to work at the same time that's the issue.

I have tried updating drivers, they're all up to date. I have tried rolling back the drivers, no success. I have tried restarting multiple times and switching cables around. I have tried finding the monitor in the Intel Graphics Command Center, but it's not detected there either.

I see that this is a problem that many people have had all over the place online, but I can't seem to find an answer for what worked in resolving it.

SOLVED: I tried updating drivers via the Device Manager, but consistently got the message that they were up to date. So I ended up downloading GeForce Experience to check for drivers there. Sure enough, there were some drivers that automatically got installed. After installing, the second monitor got detected and started automatically.
