Problem with My graphics Card?

Ok, so. I have a geforce fx 5500 and the maximum resolution is at 1024x768, and I can't change it. Now, I know this card is capable of much higher resolutions, but they are not showing. I have the latest drivers (175.16). What is the problem?! Thank you.

Added (1). LOL. I have an IBM ThinkVision L150 and the max resolution IS 1024x768. Interesting…
