Need help - new graphics card/monitor issues

[Mikeus Caesar]

I just today came to be the owner of a new ATI x1950 graphics card. I installed it, went through the hassles of installing drivers, and everything is fine, except for one problem - everything seems very slightly blurry, and there are annoying flickering vertical lines on the monitor screen, like a TV that hasn't been connected up properly.

I think it might have to do with the adapter the card came with with, but i'm not really sure. It's very annoying, because if i run it at a lower resolution, such as 1024x768 there is no lines or blurriness. Plus, i can't increase the refresh rate beyond 60Hz, so it hurts my eyes if i look at the monitor for more than 10 minutes.

Please help me!

EDIT: This is really getting annoying, whenever i am at my wits end and make a thread in here asking for help, a minute afterwards i suddenly get a bright idea, like a lightbulb appearing above my head in a cartoon. Managed to figure out a way to get my refresh rate higher, which in turn has caused the lines and blurriness to go away.

EDIT EDIT: Check below for more info - the issue still won't go away. If i start up a game the refresh rate is reset.
