Can I connect an external LCD monitor and work at higher resolutions?
Yes. Just connect a monitor and boot the eeePC. You’ll get a larger screen. This is reported to work with a Philips 190B (display of 1280×1024). Fn-F5 can be used to toggle between internal lcd, external lcd and both. If you want to toggle after booting the PC you might want to go to Settigns/Desktop mode and set Resolution manually (e.g. to 1280×1024). Some eeePCs however come configured with a maximum resolution of 1024×768. See http://wiki.eeeuser.com/howto:external_monitor for how to fix this (gives you up to 2048×2048).
