As already said, the video card you have is what you are stuck with. But I did find this one solution:
Graphics Chip: Trident XP2
Memory: 32 MB 266MHz DDR
Bus: CardBus 32bit
Connectors: PC Card Type II, DVI-I (DVI-D and DVI-A compatible) and VGA (with included adapter)
Physical dimensions: 126 x 54 x 15 mm, 4.96 x 2.13 x 0.59 inch (without DVI to VGA adapter)
Weight: 68 grams; 114 grams with DVI to VGA adapter; 218 grams with adapter and "Magic Box" carryingcase
This is good for AT HOME stuff, you can get ton's of graphic memory through a second monitor. But your LCD's graphics are pretty much stuck as is. Unless you want to over clock it and solder more memory and break your mother board..... which you should'nt do. This seems to be the best solution.
