Is there a problem with my monitor?

[Gaygle]

I'm not realllly clued up on monitors any more, but i recently purchased a Hyundai W240D PVA monitor and i cannot set my background resolution to 1920 x 1080 because when i do, it only does so at 30hz. However, when i use 1920 x 1200, it does so fine, and at 60hz. Any reason why this should be happening?

thanks
