Is it safe to use *lower* custom resolution?

My monitor's max resolution: 3440x1440p
I want to lower it to 2560x1080p, I can't find it in Display Settings nor in Nvidia, it appears it's not supported by the monitor, so Is it safe if I add it manually through Nvidia Control Panel and use it?
(I'm only lowering resolution..)

I already tried, it just not looking that good (compared to original 3440x1440p), I'm just concerned about monitor and GPU safety..

Thank you! :)
