resolution problems for plutonium T6

[ADerangedNobody]

im having an impossibly hard time fixing the resolution on t6 for bo2, i was able to go all the way to 4k on BO1 but i cant even hit 1920x1080 without the game just straight up opening and repeatedly closing on its own for BO2

play in borderless fullscreen for BO2
open console and type: /r_mode 3840x2160 press enter and type /vid_restart
if that doesn't work try /r_customMode 3840x2160 press enter then type /vid_restart
