Got my 3D-Bee Diamond in! So here are my initial thoughts and observations (and compared to the Monoprice).
Having everything setup as I already had the Monoprice, it was easy to install. Just plugged it in and transferred the cables. The Monoprice didn't like my XBox360 (in fact, it wouldn't work at all), so I tried that first. Turned everything on and... I got the 3D-Bee select your 3D type screen. Selected mine (SBS) and it worked! Nice and easy. PS3, Blu ray, TV, etc all worked too. No issues. Also, with the Monoprice, I noticed that "text" seemed somewhat jagged. Not sure if that is normal, or if there is something wrong. Everything else is clear, but text seems to be jagged. Not an issue with the Bee though. All is nice and clear.
On to testing 3D passthrough. I tried the movie Tangled 3D using the PS3. However, it just ended up splitting the images - half on top, half on the bottom. Very odd! I also noticed that going back from a 3D movie to the 2D home screen on the PS3, the images were now messed up. I had to reset the Bee to get it back to normal. So passthrough does not seem to be working. (Note: It does seem like order of connections is important for the passthrough. Not an issue for 2D to 3D though.)
Now for the 2D to 3D test. I first tried Tangled 2D - to give a comparison. (To be fair, not a good comparison - 2D up convert to natural 3D). It was no comparison. The natural 3D was MUCH better. Next I tried just the PS3 home screen, moving through the menus etc. Yes, it does give a "mild" 3D effect. The icons seem to be in front of the background. So onto something a little more challenging for the Bee... I started up Netflix. I am presented with my Netfilx experience choices screen - Netflix or Netflix for kids. Here I played with the Z and D settings (and the other Movie, Sports, Game, Popout settings). I found the best for me was Movie+. I am sure this is a personal preference as other viewers thought it was too harsh. The popout setting seemed to be straining my eyes... I tried a couple of TV shows. Nobody viewing could notice any 3D effect on any setting. Actually, the Z - - setting seemed to have the only effect - looking like things went 'into' the screen. Next I tried a cartoon movie with vibrant colors - The Reef. Here you can notice some real depth. Certain scenes, you'd notice nothing at all - looked very 2 dimensional. Others, it looked very 3D. Again, I preferred the Movie+ setting and others felt it was too much. Overall, I'd say the effect was so - so. Nothing to get excited about. The best 3D seemed to be the Netflix menu with all the movie box cover icons. There was some real depth on some of the movie picture icons.
Now on to the XBox 360. My son had his Skylanders disk is already, so I thought I would give that a go. Here again, the menus seemed to have real depth - in front of the background. The game however, would have times where the 3D was obvious and other where it looked very 2D (on any setting or adjustment).
Early impression: To be honest... Not very impressed at all. But certainly head and shoulders above the Monoprice. However, it is early; so I will keep on testing some different combinations and options. As posted earlier, some time and certain material might make a big difference...
