Black Ops 1 keeps crashing

[Ali_Barznji]

Black Ops 1 keeps crashing whenever I change the resolution to 4k in Fullscreen mode.
I've been searching around google on how to fix it but to no success, can someone help please?

Cannot open the game window/black screen on launch
How to fix black screen on launch?
Go in the bootstrapper command prompt (the console opened when you start the game)
and paste this (right click) r_fullscreen 0;r_noborder 1;vid_ypos 0;vid_xpos 0;vid_restart then press Enter

If you want to save your settings you need to do this after changing them
