I can't seem to re-create your viewing problem, ive tryed it on 3 different PC's, a regular 17 Monitor, and flat screen 15" & my Laptop...... all at the 1024 setting.....
The only thing I can think of, is, have you got the correct drivers installed for your 19" Flat Screen, although its standard it will/would seem to be working correctly, however it still might need its own drivers, just a thought
