"Why you want to play it in such high resolution??
Because todays gfx cards doesnt perform very good at low resolutions, like im on a GTX470 1280MB and no matter what game i run the fps starts to drop massively when i go below the 1600x1200 resolution.
Even on my old cards (2x GF8800GTS 320MB) i had severe FPS impacts going in low res.
Also by todays measure 1920x1080 isnt that "high" really, even the low-budget 22" TFT widescreens is at least 1680 wide and almost any 24" wide u get out there will be 1920 wide or even more.
The game supports higher resolution indeed, but not thru the ingame settings though which is actually weird, but they prolly had their reasons to make it so.
The solution is to set the resolution manually in the scr-file the game use to store GFX settings in.
1. Go to the games installdir [installDir]/4x4hummer/Data
2. Create a new txt-file on your desktop and open it*
3. Drag the file VideoSettings.scr to the txt-file u just opened
4. Set the different values to your likings
5. Press CTRL+S or go to "File>>Save" to save your changes.
*You may not be able to open the scr-file directly and therefore i put in the solution with dragging it into an existing txt-file.
Note: Remember to set the refresh as well or the game wont run.
Also you cant change gfx settings in-game without your newly created resolution will be reset by the game.
This solution worked well for me, im now running in 1600x1200@72hz (old CRT).
