I had this same problem with the 19" model as well. I had to reinstall video driver with the tv hooked up in order for the resolutions to work properly. In order to do this I used an S-video cable which worked well enough to reinstall the video driver. I did not try safe mode which might have been easier, I just did not think of it at the time. With the video driver reinstalled while the TV is attached to my computer, I know enjoy a crisp 1440x900 screen resolution. Hope this helps.

Make sure that you set your laptop to external display by using the proper F key, located on top of the keyboard. It looks as though there are two computer monitors on it. My Gateway is F4 for example. Press the function key and the proper F key simultaneously. There are a few choices, so you may have to push it more than once. I hope this helps and good luck!
