I've stripped my a150x1 monitor. In so doing I negelected to mark the panel so I can orient it properly. How can I tell top from bottom right from left etc on a stripped monitor? Also as I'm building a verticle box using a mirror I need to account for the projected image being flipped by the mirror. I can't seem to visualize how to install the panel so I won't have to stand on my head to watch. Thanks for any help.

The way joe explained it to me, if you're facing the front of your projector looking down the inside from above, you should see the picture correctly. I haven't put mine in yet to verify, but he's the only one I know with experience there.

Check out this pic of Drudgemart's projector. He's using the same monitor. You can see the orientation of the board comming off of the monitor.
