Lowering screen resolution in an ultra wide screen monitor from 3440x1440 to 2560x1080

[mahmoudm10]

Hi,
I got a new ultra wide screen monitor today..
Asus ROG swift PG348Q, 100hz, G-Sync, max resolution: 3440x1440 (21:9)

I'm trying to lower the resolution to 2560x1080 (same ratio: 21:9), but I can't find it in the list of screen resolutions, the only 1080p resolution is the 1920x1080..

I tried to change resolution through Nvidia Control Panel, it's also not listed there..
I updated gpu drivers through Nvidia Experience and through Device Manager..
Also downloaded the Monitor drivers from Asus website, updated the monitor in the device manager..

And I still don't have it..
What am I missing here?

Thanks

Set a custom resolution. See section 6.3 here: http://www.tomshardware.com/forum/id-3675170/connect-120-display-construction.html

Thanks Glenwing, is it safe though?
