actually, there are 4-variants of the 226BW panels that i know of: A-AU Optronics, C-Chimei, S-Samsung, the other one i can't recall. as of now no way of knowing if you're getting one or the other panel. at least with the 2232GW, wala pa. limited lang kasi reviews. hehe.
as to the next question, i think gagana naman yung 9250 mo. what you can do is inspect the driver inf. see if it includes the 1680x1050 resolution. one thing sure though.... even me native support vidcard mo for that resolution, it won't play games at that setting.
