windows 11 with LG ultrawide monitor

This solution works for me for monitor 29WN600

Interesting. Last week I bought an LG Ultrawide 34" monitor to replace 2 x standard widescreen monitors to run with my Microsoft Surface 8 running Windows 11. I plugged in the new monitor into the Surface loading dock and then went to set screen resolution. Exact same problem as you had!! Windows did not offer any resolution better than 1950 x 1080 when I tried to set resolution for the external ultrawide monitor. Tried everything - watched useless "help" videos on LG and Windows support, read pages and pages of forum support articles, and even had a soul-destroying and completely unsatisfactory experience with LG's online chat system (seriously, it was worse than useless - at one stage actually gave me instructions for an LG washing machine....). Then, on a hunch I got a USB C to HDMI adapter, plugged it directly into one of the two USB C ports on the Surface itself (NOT the docking station), then went to monitor settings. To my complete surprise a whole new range of resolution options came up in Windows for the external ultrawide monitor, including the correct 2560 x 1080 option!! Selected that and BANG - everything is perfect!

I only tired this because when I had the monitor connected via the docking station, Windows did not offer these resolutions for the LG monitor BUT did offer them for the screen built into the Surface, so I knew the settings were there. Seemingly with the docking station or the Microsoft Mini monitor port cable (which converted to HDMI to connect to the monitor) prevents these extra resolution options from being displayed.

It cannot be possible that I am the only one to discover this, but in my case - and after a very frustrating few days - the situation is resolved.

A bonus is that I can now use the LG monitor driver too, which gives many different screen split options.

I have a related problem with LG 32UK50T HD monitors (3840 x 2160) connected HDMI-HDMI (with certified 8K/"Ultra High Speed" cable). These monitors automatically go into "power saving shutdown" after a short time of no signal, e.g. "turn off my screen after 15 minutes" (new HP Pavilion laptop, Iris Xe Graphics, delivered with Windows 10 Home and just upgraded to Windows 11, resulting in installation of the Generic PnP Monitor driver). Once the signal from the laptop is shut off by Win11, the attached monitor doesn't respond properly when the signal is restored by waking up the laptop. It appears some sort of "wakeup" signal is sent, the monitor sort of wakes up, then decides there is no signal and goes back to sleep.

My workaround is to either disconnect/reconnect the HDMI cable or switch the monitor input from HDMI1 to HDMI2 and back again, after which the monitor is alive and well (until the next screen turn off).

I'm contemplating (re)installing the LG "Ultra HD Driver.zip" for Windows 10 I've downloaded from the LG support site, but haven't yet.

You saved my life!!

Many thanks, that worked for me after 3 days searching for a solution.

Thanks a lot!

Hi, I have the LG 34 ultrawide monitor which did do the 2560x1080 in Windows 10. On Windows 11, I was able to get this resolution to work for about 10 seconds before it began to fritz. So, I selected a different 21:9 resolution, i.e. 2432 x 1024. I did this because my computer is a Dell and comes with an NVIDIA Quadro P1000. I was able to download the latest drivers from NVIDIA and use NVIDIA Control Panel as follows:

Display > Change resolution

Click "Customize..." button

Click "Create Custom Resolution..."

1. Select displays

LG Eletronics LG HDR WFHD

2. Resolution settings:

Horizontal pixels: 2432

Vertlical lines: 1024

Refresh rate (Hz): 59

Color depth (bpp): 32

Scan type: Progressive

Timing:

Standard: CVT reduced blank
