HOW-TO: 3440x1440 res on 5120x1440 monitor (21:9 on 32:9 monitor)

Hi all.

I just wanted to share a solution I found since it took me way too long to find it myself.

In all my games I did not have the choice to get the 3440x1440 resolution on my 49 inch G9, so that I could play ultrawide with fx discord and steam on each side and the game in the middel.

I found this video as guide: https://www.youtube.com/watch?v=NDS8sKXgCog&list=PLSTnpjXX91ZohFv6Yeck8vRrMFD9_Dk3t&index=1&t=4s

Step-by-step:

Find the registry editor

Search in win

Use find under edit

Type: nv_modes and search

Open it.

Add to the end: 2560x1439x8,16,32,64=1F;3440x1440x8,16,32,64=1F;

It should be added after the 8032; as the last thing in the string.

Press OK and restart you PC.

The option of 3440x1440 should now appear in your game settings.

Tested in The Witchter 3 and CS.

Update 11.09.2024: If the fix no longer works, check the registry again and see if the added string has been removed - has happend to me a few times now.
