Thanks, Fury. Although the nice thing about these big (23") HD LCD LED monitors is their inherent brightness - at the "standard" brightness and contrast settings they're ridiculously bright, especially with a white background (you'd better be a brightly lit room or you'll need sunglasses to look at the screen).
Even this brand's "Eco" setting is too bright for my warmly lit office. I finally settled on a brightness setting of 20 and contrast of 30 and it looks splendid in FSO and all of my other games - while still looking good online and in Windows Explorer and such. The above launcher settings for FSO darkened everything in-game a bit (giving a nice look of realism) but it's still possible to see targets at a distance.
Anyway, once I got everything tweaked for this new monitor, I'm quite happy with the results.
