I just tried the Acer 11 inch Chromebook, that use to be mine, now the kids', and just a minor modification to get the dual screen function. It has an HDMI port as well so, hooking the HDMI/HDMI cable up to TV and chromebook, then going to menu on TV and select HDMI selection. Since the acer does not have the right and left click bar at the base like the HP Pavillion, you have to depress the touch pad on the side closest to you or its base with your left thumb, while you have the cursor on the tab just left of the x, and then while keeping the base of touchpad depressed, use your right index finger to drag tabbed page to the TV screen by pulling right.
