You can't add a video card, no - some notebook models have the option of discrete video, but it's a chip soldered to the mainboard, not a card -- on this model, that doesn't appear to have been offered, so the only way to get better video is with a new system.   You can't upgrade what you have.

Hi CMWH,

As correctly said by ejn63, the Latitude E5430 system has integrated graphics and does not support discrete graphics card.

Please refer the following link for the Latitude E5430 Owner’s manual to view the system specifications: http://bit.ly/14jE3MP
