So my Dad has a laptop hooked up to a smaller lcd he uses both screens and I guess the charts stop running. He's called everyone from sony to etrade to our isp. Now they are saying it could be the laptops video card. Do you guys think this could be? It's a sony Vaio 2Ghz P4 with 512mb of ram and a ATI 9100. (I think 245m). This seems like the laptop should be able to handle running streaming browsers on the 14-15LCD plus other stuff. Any ideas or thoughts?
