To power it on:
When it first powers on, it takes you to the built-in Windows computer. Feel free to use this computer and the apps that are installed. The TV will act be touchscreen in this mode.
If you need to type, an on-screen keyboard will appear. A regular or bluetooth keyboard can also be connected to the computer (which is mounted to the back of the TV)
If you connect your computer to it using your HDMI dongle, the input will automatically change to your comptuer:
Translation: "I'm switching inputs now!" Yes.
Now you can use the TV in the same way you'd use your projector. The screen will not be touchscreen in this mode, so you'll control your computer using your built-in keyboard, trackpad, or a powerpoint clicker, if connected.
If you touch the little white dot that's always on the screen, you'll get a menu
Feel free to try out the different options. The Chrome browser is very slow. The whiteboard is pretty neat. Just draw using your finger
The TV is on wheels and fits in the elevator, so feel free to push it to whichever room you'd like to use it in. Please roll it back to the SLC when you're finished so we know where it is and the next person who wants to use it will know where to find it.
Also, feel free to experiment with any of the other features that interest you. It has a lot of functionality - I've only mentioned the ones that I think would be most useful. You may find something that I haven't discovered.
