Just in case someone else runs into this...I've been running a 17 inch monitor at 1280x1024 for years now, without incident.Yesterday, I took the plunge and upgraded to a 22 inch LG monitor at 1680x1050 resulution.All went well, until I tried accessing the menus in FSX a second time (first time was OK, changing resolution).. At 1680, I could drop down the first level menus, but then FSX got stuck..Following a hunch, I changed the AA setting in nvidia properties from override to enhance and bingo, FSX worked again.Strange, but that was it... 163.71 drivers.

One more observation:The colors on this display did not look right, until I changed the factory settings:Brightness at 50% instead of 100% !!Contrast at 70% same as shippedand color temperature half way between the two marked settings.I also set WideviewAspect to true in the fsx.cfg file and fly at 80% zoom. WVA=false and zoom=70% produces about the same view..Now, the screen looks phenomenal and both FSX and FS9 are a totally new experience !

The default brightness that some of these LCDs are shipped at they can double as lighthouse beacons.As for WideScreen=True that equates to a 60% zoom on my 22" so by enabling it and zooming at 1.00 you get a more natural look at a 0.60 effective field of view.
