CRTs are another story - my spare machine can do better 1600x1200 with a CRT and autodetect logic often sets it lower. Anecdotal evidence via my eyeballs tells me it's because it first figures "optimum" frequencies to run at, then picks the best resolution for that frequency. Personally I don't see the need to run that monitor at 85Hz, lower frequencies are just fine for me. Pre-hal Xorg will do what you tell it to. Post-hal Xorg apparently does what a toss of the coin tells it to. -- alan dot mckinnon at gmail dot com
