What I'm going to say is just something to think over, because it is very cheap solution for 3D on this PJ or any 2d hdtv.
I could stop there, but , I will share a little experience with it owning it less than 24 hours.
Now, if you do read the reviews on amazon, read the newest ones first, and go backwards, very important. Why? Because the company put out a firmware that added "brightness feature" to the unit, so if picture is dark, you can in addition to adjusting the brightness on PJ, you can also crank it up on the device itself.
Now, what do you get for 35 dollars. First of all, you get 2 hdmi inputs, so you could put pc and 360 into unit and switch via remote. You get heavy gauge hdmi cable. You get 2 passive 3d glasses. Not bad for 35 dollars. Oh, I forget the unit itself.
You get 3d on xbox, I went to console settings and I saw the option , and enabled it and watched You Tube 3d sbs , and it was amazing! Worked great. Now the 360 and just the Pj will not enable 3d, but this device will!
Now, of course it will work with any device, pc, ps3, etc. I can get good 80 inchs in 3D! Works best with 3D material. It does have 2d to 3d conversion, and depending on the tv show it is good to just ho-hum. But if you got blue ray 3d player, for 35 dollars, you could do a lot worse.
I tried it on my 2d hdtv's and it worked great too. So, even if you hated it on the pa70g, you could throw it on a 2d hdtv and I think you would be happy.
We are still working on getting 3d on our beloved pa70g, sounds like we are making progress, keep up the good work guys.
