One time I was changing game settings, but I set wrong game play resulution( dont remember what did I change that to, but not as my computer screen 1280*1024).
After that, everytime i try to run CS 1.6 there is black screen with text:
"Video mode not supported".
Can anyone help me???
Go into your program files ->steam -> steamapps -> account name -> counter-strike -> cs folder and look for your config files. There is an option in there that sets your screen resolution. Reset it to somthing like 1024x768 and then redo your settings ingame to whatever works for your monitor.
