I recently purchased a BenQ MH680 projector. This projector is advertised as having 3D capabilities. I ordered at the 3D Glasses II to go along with it.
Having now received the glasses, I wanted to give it a try. Gravity, Hugo, and Avatar seemed to be good trial candidates. Gravity and Avatar I have as Side by Side, while I have Hugo as Over Under.
It took a while to figure out the correct settings, and to determine how to make things work. Here are my thoughts to help make things easier to configure next time.
For each of the two scenarios, side-by-side, and over-under, there are a couple of common KMPlayer settings. The right hand advertisement box can be made to go away by clicking on the 'box' slider in the upper header.
Right click in the main window to bring up a menu. In the '3D Screen Controls', set for 'Do Nothing'. Double Click to go full screen. Start playing the video. While playing the video, you should be aware of the following commands from the menu: 'Pan & Scan' -> 'Frame Size & Position'. These are handy keyboard keys to remember. They are used to tune the frame settings to optimize the 3D viewing environment.
width - ctrl 4 4 move left width + ctrl 6 6 move right height - ctrl 2 8 move up height + ctrl 8 2 move down
On the projector, bring up the 3D menu. Select 'Side By Side' or 'Over Under' as determined by the movie type. Then use the numeric keys mentioned earlier to tune the viewing experience. Especially if you are seeing double images.
If you see an inversion of depth, use the '3D Screen Controls' -> 'Swap Frame Order' menu item. These should provide the correct depth of view.
