Something weird happening with my 3D-XL. Had it for about 5 days now, and I'm using PS3, SKY HD box with 3D, and a Sony 3D Blu-Ray player, passed through a Sony HT-AF5 5.1 system, then onto 3D-XL then Optoma HD67 (UK version of HD66). Using HDMI 1.4 to HT-AF5 (3 x 1m 1.4) then 5m 1.4 HDMI to 3D-XL then 5m 1.3b HDMI to the HD67.
The 3D aspects of the 3D-XL are superb. It handles everything you throw at it either SBS or interlaced. Amazing depth and colours, and all works flawlessly. There are the L/R syncing issues as mentioned previously, but HD67 has a 3D invert button on the remote so very easy (and obvious) to fix.
Reading the CD that came with the 3D-XL it states that there is pure 2D pass thorough, but I don't believe it. Prior to getting the 3D-XL I had a HDMI splitter bridging the 1.4 HDMI cable and 1.3b HDMI. Picture quality was outstanding whether playing blu-ray player or watching SKY HD both on 1080p. Optoma HD67 says 1080p (and relevant Hz, 24, 50 or 60). However, when passing through the 3D-XL, same sources say 1920 x 1080 and 60Hz. Now I know these should be the same, but why is the HD67 recognising a different signal. And it's clear the output is different. The signal is much more pixelated, and not good for anything that moves quickly. Almost as if its upscaling a 720 signal. If I switch the signal away from the 3D-XL and back through the HMDI splitter, all is well again. Any ideas??
