Hello, I hooked up a Compaq MV540 Monitor to my laptop as it is easier on my eyes and posture( I also have physical disabilities so it is easier on me) Should I buy and use a Video Card and what kind is best? My laptop is a Toshiba

you cannot upgrade your video card on the laptop.
Should be added that although you can't upgrade the video card, there is no need to do so just because you are using an external monitor.
