Please do not rate until you area completely satisfied with this session. when rating please RATE 4 or above. Have you tried pressing the menu button on your remote, then press the down arrow key until the menu cursor is positioned on the installation tab. Once you see the cursor move it onto the image flip selection then press enter. You will have to go down to whichever Alphabet that you need to flip it: HV is for horizontal and vertical, H is horizontal only, V is vertical and off means the picture doesn't flip or rotate. You will have to press the enter button to go through each one to get to the one you need to flip in the right direction.
Once you do that, then press the menu button to save your selection and to exit. That should get your image to rotate on your projector.
Just checking in to see if my instructions above has worked and if I can be of any more help. Please keep me posted by replying to this post. Thank you.
