How can I set up the Origin Store version of Command & Conquer: Generals to run a full HD?
Solution 1:
I know it's probably too late since you asked. But I know simple solution.
Just download the patch that fixes problems with the game, such as setting the resolution, optimizing the game, repair multiplayer servers (by GameSpy server shutdown).

Resolution settings are possible after installation, in the in-game settings.
