Dude stop calling me dude. If your monitor is so good, you'll have no trouble buying some proper equipment, and MAKE THE WALLPAPER YOURSELF. You must be a troll, because if you can't afford Duke Nukem on the XBLA you can't have a 24" monitor. I rest my case. I have given you a wallpaper, which is large enough for a 24". NOTICE: I HAVE TRIED IT ON MY OWN 24 . I am a nice person. Have the brains to work outside the (Orange) box. make the Start menu bigger or something to wipe out the black space on Centered setting if it bothers you that much. Stretching it will make barely any difference.
Do you expect a game as old as Duke Nukem 3D to have HD wallpapers that are over 9000x4000 in size? The answer is you won't find a bigger image of the one I have sent..
If you want my advice, go on google images, type in "HD wallpapers" on the Large Picture setting and pick a picture of a rainbow
