    Quite simply, when I play a 3D film I have to crank the brightness way up to the max to be able to see properly in dark scenes. Bright scenes benefit from this as well, since without brighness being cranked up normal daylight scenes look like thy're being shot at dusk.

    I have a Panny 50VT30, using THX setting. With normal viewing I have the brightness setting at the standard point, ie half way.

    Is there something else I should be doing instead of whacking the brightness up so much?

    It's just how active 3D displays work, if you imagine both 3D glasses lense shutters switching on/off many times per second they are letting less light through. Some active TV's automatically increase brightness levels when 3D is switched on, not sure about your model.
    My advice would be to watch 3D in a dark room because if you increase the brightness too much (From what I've read) you are probably increasing the chances of getting crosstalk.

    This is one of the main reasons I chose passive over active. I have enjoyed using my shutter glasses for a couple of years but usually watched 3D material in a darkened room. One thing that I loved about the LG Cinema 3D technology demo that I saw was that the image was as bright (OK maybe there was a 5-10% reduction) as a normal 2D TV and could be viewed nicely with the 3D glasses even in a brightly lit showroom in broad daylight. That was the seller for me and the 1080p image looked beautiful even though I knew that it was half resolution....my eyes couldn't really tell...the extra brightness seemed to help there too.

    But as long as yuo're not watching in half-SBS or half-OU and have the correct Tru-Motion set then it wont be :confused:

    Check out your set with the test card at the end of this thread to prove it:

    ....and make sure you post if you find differently :)

    :confused:

    I don't watch in half SBS or OU and I don't have Tru-Motion on my set as its just a cheaper 23" TV/Monitor.

    In that case perhaps it's not Full HD as it would depend on how it's driven and the true specs. of the monitor.

    I think there's some confusion here. :facepalm:

    I have the LG DM2350D TV/Monitor which IS full 1080p HD (at least in 2D mode).

    LG DM2350D Monitors - 23" LED LCD 3D Full HD Monitor TV - LG Electronics UK

    The point I was trying to make was that the LG passive displays are interlaced so in theory each eye is receiving 540 lines per eye in 3D mode instead of the full 1080.

    Personally, although I am aware of this, I don't notice it and it doesn't spoil my enjoyment.....the LG 3D Cinema image looks very nice to my eyes.:smashin:

    ..and potentially Full HD with both of course since obviously you see 1080 lines and not 540 - hence my original post.

    I can't guarantee it is with your set-up, as it will depend on the display algorithm, but it should be easy to verify as suggested.

    OK. For the sake of argument I'll call it the following.....

    1) 2D= Full 1080p
    2) 3D= Full (brain interpreted) 1080p :D

    Whatever it is, it looks darn good to these eyes both before and after brain interpretation. :)

    The brightness controls the black level try increaseing the contrast a bit i use thx with the contrast at about 75%-80%,the brightness down 1 click,colour down 2 and sharpness down 3 and vivid colour on when watching 3d i find it more than bright enough.

    Jason, it was never a criticism in the first place. I chose passive over active myself because of the fact that my eyes don't notice any decrease in PQ. In contrast, a lot of people use the half resolution argument on several websites in order to prove that active is better than passive. I disagree with that argument. :smashin:
