Hannspree monitor flickers and shakes at 1600x900 resolution

Recently my faithful old 2000 monitor burned out, probably due to too much color correction. Yesterday, I bought the cheapest monitor available at Best Buy, a HANNspree 20" flatscreen. It says on the box that it's supposed to run at a 1600x900 resolution, but when I set it, the screen shakes. Any other resolution is fine. I have NO idea what on earth could cause this. It isn't a problem with the monitor itself, it works fine on my other computer. I already spoke with their tech support once, and all they had to say was that it should work fine with Windows XP as long as I had it set to a 60 Hertz refresh rate, which I do.

Any hints?

Just in case it matters, I'm using an NVidia Geforce 7300 graphics card, with all the updated drivers. I'm not sure what other information would be helpful.

 

My guess is that your graphics dont support that res, most common is 1600x1200--1680x1050. ed
