[ltp] max resolution for the second monitor

[fuchur]

hi all,

I'm thinking of buying myself a new second monitor. my problem is, that
I don't know what max resolution my notebook supports.
I have a T42, running 1400x1050 on the first screen. lspci tells me I
have a 'ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]' graphic
adapter.
after 30 minuts of searching I couldn't find any information on how high
the resolution goes. can anyone please help me out?

thanx
jan
