Thanks for that Jim... I'll try Ctrl-F5/Ctrl-F6 tomorrow and see what happens...

In the interface I'm using, 'Enable advanced in-game settings' has to be checkmarked for those keystrokes to work. Once they are set properly, hitting CTRL-F7 will save them.

Thanks Jim, I would have missed that. I enabled it and while Ctrl+F7 and Ctrl+F11 do stuff Ctrl-F5/F6 appeared not to do anything (but see on)... I also found Ctrl-T turns off 3D but you still can't get to the control menu.

One other thing I did is to run it Windowed on a 3D desktop (1920x1080 24Hz) and that looks impressive too, here being "into" the screen a little helps with the effect.

Anyway, after some online research I got the tip that you really have to hold the convergence keys down for a while to be able to spot anything (also that there is no on-screen indicator that anything is happening, unlike the depth control). So I went back for try two and that is the trick. I found Ctrl-F6 is the one to move the tank towards you, and when you go too far it all falls apart very obviously. I now have the gravel at about the screen front (although a couple of fish seem to slightly swim out of the TV, just by a cm or so, so perhaps I'm not exactly lined up yet. As a lot of the tank is much closer now the 3D offset (without glasses) is lessened and the apparent depth increased (so I also took the depth back to about 60%). I then used Ctrl-F7 to save my new settings.

BTW here's some links to the 3D Play Q&As and other info:

Also note anyone with a Nvidia 3D Vision Emitter can plug it in and 3DTV Play will be licensed to run. Otherwise the US price for a Key is $39.99 and the UK one £24.90. Unfortunately the best price I've seen for Glasses+Emitter is £69.99.

Thanks for your patience, John - I'm so glad SOMEONE found the Convergence control. I should have mentioned that you have to hold down the key for a long time before it takes effect.

But this is exactly why 3D just isn't ready for prime-time. If it took this much effort for a video professional to adjust something as vital as Convergence, how is the average person ever going to get it?

Well, the Marine Aquarium users can read this thread :-)

Isn't there a message in there somewhere? ;)

Sorry, Jim. Call me a cynic if you must.... ;) - But I would choose HDTV, any day, over 3DTV. I think I must have lived through at least three or four reincarnations of 3D over the decades, - all of them failing to catch on. - When will they realise that it's doomed to fail?

OK Cliff, you're a cynic. ;) :D

Cliff - I don't disagree that 3D is not ready for the masses. But it will eventually become the norm for one simple reason: TV has nowhere else to go. People are not interested in any further increases in size or resolution, and the manufacturers MUST come up with something to keep selling hardware.

I agree that the manufacturers will want to keep selling us hardware, but I don't believe that 3D will be the answer.... We shall see!

Why 3-D TV Has Been an Epic Failure
Future looks flat for 3D TV

I always will choose the 3D version at the movies if it is available. Today we watched "Cloudy with a chance of meatballs 2". It's a cartoon, and aside from two or three extreme 3D scenes where something goes flying by the viewer's head, I totally forgot I was watching 3D and it just became another HD experience. So if I am only going to appreciate three quick scenes in 3D, why bother. I love 3D, but there has to be more to it than this. It reminds me of the title line in the song "Is that all there is?" Maybe the producers are being lazy by not including more 3D scenes. Not sure, but I will be looking forward to improvements. We are in the Wilber and Orville stages of 3D, and I can't wait for the shuttle era to arrive.
