1920x1600 on the 15.4" laptop and the 17" models too they have cheapened up the resolution to 1680x1050 and the characters are too blocky and awkward, although they fit the grid in terms of visualizations for trading purposes, choose 2 screens for the stability and the laptop for times when you have to be mobile and downsized, but not as the primary platform to trade from
I'm making my LCD/notebook size decision as well. Could you explain more why flat panels smaller than 17" don't have enough pixel for trading? Does 17" have bigger font with native resoluation than 15"?
