On my 10.3.9 machine, there is no "Graphics/Display" in the left pane -- the information on the graphics card is in the "PCI/AGP Cards" listing.

(That's a desktop machine, but I think a laptop has a similar thing.)

Worse comes to worse, if you post your machine's specs (processor type and speed, plus the amount of RAM), it might be possible to guess what the video card is.
