Ok I bought a Samsung 225BW LCD yesterday and it was fine pretty much ok with FS9 and FSX. Today I run FS9 and FSX and the menu appears only in the first half of my screen while the other half remains black. I tried reinstalling my video drivers (7800GS AGP Extreme). I tried deleting the CFG files. I tried switching the LCD from VGA to DVI. I tried different resolution settings and after all that I still get the same problem. I've included a screen shot of what I mean. Any ideas? This is so annoying. Thank you.

I just solved my own problem. It seems that this issue only occurs when my AGP Aperture is set below 256. I forgot that I was playing with it last night. Once I set it back to 256, the problem in FS9 and FSX vanished. It also resolved the problem from my other post where FS9 and FSX would not accept any resolution higher than 1024x768.
