I have done something, or have installed an update that has cause me to be unable to display my monitor at any acceptable resolution.
I am told the native resolution is 1920 x 1200, but now, when I try to set that resolution, I get a monitor alert window saying "out of range"
I also get this at 1856 x 1352. I have to go to 1600 x 1200 before I can get the settings to take, and this is the wrong aspect ratio.
I have downloaded the latest drivers for the monitor and for the graphics accelerator.
I have use a restore points back to February, but no luck.
