windows 11 with LG ultrawide monitor

Not sure if this was mentioned anywhere here, but for me it turns out the problem was not the driver, but the HDMI cable I was using. I kept whatever old HDMI cable I had on my old monitor, and ran into all the usual "wrong resolution" / "no higher resolutions availble" issues. Turns out no all HDMI cables are the same, who knew.. (everybody probably). Switching to the privided DisplayPort cable fixed all issues. I didn't go back and try the HDMI cable that was in the box, might work fine as well.

Edit: this was connecting a Surface Laptop Studio (i5, iGPU) to the 35WN65C-B.AUS via an Anker 11-in-1 USB-C dock.

I also have a LG 34 inch ultrawide monitor (21:9 aspect ratio, 2560x1080 resolution).

During the update following the Windows 11 update, the same thing happened to me.

I followed the top rated comment to reinstall the old Windows 10 LG drivers. I also got them from here: https://www.lg.com/us/support/software-firmware-drivers?customerModelCode=24GL600F-B&csSalesCode=24GL600F-B.AUS&category=CT10000030&subcategory=CT10000033 

It didn't seem to make a difference. I also restarted, no difference.

I then accidentally bumped and disconnected my windows Surface Dock 2, that is used to connect my surface 2 laptop with two external monitors. For reasons that make no sense to me, that disconnection and reconnection of the dock made the drivers take affect and suddenly it switched to 2560x1080 resolution and the LG Ultrawide screen looked perfect.

If you're using a surface dock 2, you might try to disconnect and reconnect it after making sure the LG drivers are installed. Not sure why that caused things to work?

I have just bought an LG Ultragear 32GP850-B monitor with G-Sync.

Unfortunately Windows 11 only uses a Generic PNP driver in device manager.

After searching the LG website and even contacting LG there are no drivers available for this monitor.

In Nvidia control panel the monitor appears as LG Ultragear and next to the Generic in device manager (LG Ultragear)

appears in Brackets. But unfortunately Windows 11 is using a Generic driver released in 2006 for this monitor and says its the best available.

There is also no Windows 10 driver available. Anybody have any ideas what I can do? Having some issues with Monitor buttons stopping working after playing EA/Origin games. Steam games work fine.

Thanks

It usually helps to get the monitor to identify correctly. You can use the monitor drivers from LG. My monitor worked fine and did show its correct model in the Device Manager.

Cables that convert the connection like DisplayPort-to-HDMI or HDMI-to-DisplayPort may cause problems with EDID and these resolutions problems. This was my case.
