Windows 10: Resolution issues with LG ULTRA WIDE 2560x1080

Dell Inspiron 15 3520OS: Windows 10 Pro 64bit 22H2 19045.4355Hi friends, I'm having a problem with my Dell laptop. It won't let me set the resolution to 2560x1080. According to the information I've checked, my processor supports high resolutions, but for some strange reason, it's not recognizing the correct resolution. I've already updated the drivers more than three times and still haven't found a solution.

Ultra Wide monitors (21:9 ratio) doesn't work on Windows 10

For Ultra Wide (2560x1080) the ratio is 21:9 - not 16:9

 

Can't change to 2560x1080 Resolution.

Hello there. I have been dealing with an issue for a long time regarding my resolution. I want to change my display resolution to 2560x1080 (ultrawide), but I do not get the option to do it. I have tried to fix it, but I've got no idea how. I tried "List All Modes" thing, and some other stuff to fix. Didn't work out. My resolution is forced on 1920x1080.

I have a LG Ultrawide monitor, which has a 2560x1080 Ultrawide resolution.

The AMD Radeon HD 7400 series encompasses a range of graphics cards with varying capabilities. Some models may support higher resolutions and ultra-wide displays, while others may be limited to lower resolutions. So it will be helpful to know exactly which model of the GPU it is.

Did you add this GPU as a modification for the hardware at one point? Has this set up worked in the past for ultra-wide resolution? What port do you use?
