There are two options for native screen display under Display Properties >> Settings (XP SP2):
1. Plug and Play monitor, max. 1280x800 px
2. Default monitor, max. 1920x1080 px
However, when selecting 2, and increasing resolution beyond that possible by 1, nothing happens when you click Apply. There is no docking station and I'm intersted in the built in laptop monitor.
Thanks if anyone knows of this issue.
