I'm looking into buying a laptop for all my non trading related apps/files. I would like to use the external VGA to connect to my center 24"(1920x1200) screen. I talked to tech support from HP and they said they didn't carry a laptop that would support 1920x1200. So my question is, are there any affordable laptops out there that would support 1920x1200 through an onboard video card? Or will I have to buy an some sort of external device? Thanks.
