Info from Tru3d : Thought it may be useful for others.
If your 3D-XL was not marked as having updated firmware from July '11 or newer, then please goto our site and download the latest firmware available. The direct links are at the bottom of this FAQ.
The 3D-XL will only switch into 3D mode for supported resolutions and signal modes. Please check the HDTV output settings on your cable box or other device to make sure that it is out-putting the 3D channel in a resolution supported by the 3D-XL. Note that there may be differences in the list for side-by-side vs. above-below content.
Additionally, please make sure that the switch on the back is in the 3D 720p position and that it did not accidentally get flipped during installation.
Please see the July '11 supported 3D mode list below:
Frame-pack:1080p24, 720p50, 720p60
Over-Under: 1080p24, 720p50, 720p60
Note the difference of 1080i60/50 for Side by Side vs. 1080p24 for Over-Under. Also Notice that Side-by-Side is not supported in 720p60. You will need to check the resolution and 3D format for any channels that require trouble-shooting. You may be required to manually adjust your cable box output settings to support your 3D viewing preferences and to conform to the Optoma 3D-XL 3D mode list.
If selecting a different resolution for the problematic 3D channel does not resolve the issue, then we recommend that you update your cable box or service to a solution that provides the frame packed method on all channels or Certain older cable boxes may not be sophisticated enough to automatically switch resolution modes for mixed-mode 3D programming for services that offer multiple 3D formats in their line up such as an above-below channel, a side-by-side channel and a frame-stacked channel.
I can not yet post URL's but if you can find this via search engines it links to firmware installation instructions and the latest firmware.
I will update if this solves my problems.
EDIT: I was able to display a Motorstorm Demo Game in 3D
. It was an awesome experience. Might still be a firmware issue if i cant get their Demo Video to play in 3d. PS3 3d games output to 720p and the VIDEO was 1080p. Still no 3D bluray to try . Thanks for previous help.
