Mine is the older 1420 version. My graphic card is 8400M GS. do you guys with this newer model have better graphic card?

I am planning to get a 21.5/23 inch external monitor to connect with my 1420 for extended screen (dual screen). the monitor that i'm eyeing has a max resolution of 1920x1080.

i wonder if this will work out for me or not.

my current configuration is c2d 1.67, 2gbram, 8400m gs 256mb gfx, win 7 pro.

pls help D;
