21:9 on csgo(?)

I have this monitor:

LG 34" Class 21:9 UltraWide Full HD IPS Curved LED Gaming Monitor with G-SYNC (34UC89G-B)



there are many games like PUBG that are perfectly designed for 21: 9 but cs: go lacks some optimization in the sense that the HUD can be reduced perfectly but the arms in the store of purchase go out of square and the texts when the CT or T teams, win, or lose, they come out very large and you do not finish seeing correctly, the same happens with the TAB and the loading screen of the map, is it possible to edit the size of all this in a file?

I think that one is an overkill for CS:GO. I use 24" LG for CS:GO and I actually lowered the resolution to 1440x1080 . The one you're showing above would be too big for me. So my bet is - go for something smaller .

yeah nah, just experiment around with those things, it's easier
