questions before buying BO6 product

[MomySlayer]

Hello, i have few questions about BO6 product 🙂
First is it compatible with widescreen ? My monitor is 3440x1440 and i know some products require standard 16:9 ratio.
Does it work in fullscreen or it have to be windowed please ?

i think that's all i need to know, thanks in advance for the answers :D
