MAMEWorld Forums - EmuChat - Vector Games not filling Verticle screen

Me and my dad built an Arcade cabinet for MAME, running version 0.36 with the UI. (please don't just say GET DA LATST VURSHN) Now, I put MAME on my own computer before, and everything worked just fine. On the computer we put in the cabinet, though, it has a couple issues. Mainly, all the vector games don't fill the screen. We have the monitor rotated 90 degrees clockwise, with the computer's own video 'card'. All the raster games show just fine, but vector games are ALWAYS stuck in the right or top side. If I set the screen tall, I have to change the settings of that game to rotate it (unlike other games), and then it gets epicly stretched wide screen. If I leave it on automatic, it's top is the monitor's normal top, and at the monitors normal total left. Same if the screen is set to be on a horizontal aspect ratio. Basically, vector games are always oriented opposite of the screen, and stuffed into the side. Any help? Also, 1943 has some parts of it missing, the grey in the ships, the black behind the health bar, so forth. Strangely, it all works perfectly on my computer. (I hope that was understandable)
