side-by-side 3d televisions

[arnoldemu]

I've just seen a cheap 3d television/monitor from lg that supports side-by-side 3d.
I say cheap, it's around £130.

the type of television where an image is split into 2 pictures horizontally, one for left eye, one for right.
You get "polaroid" glasses with it, which are cheap. (£2 each or so)

The software in the monitor mixes the left/right into one image with even lines being left eye and odd lines being right eye.

So, has anybody tried a cpc on one of these televisions....?

I am wondering this...

if I can fit it into my 16kb game, and if I drew left/right images appropiate for this kind of television, would it display AND work?

Do you have a link? The price is very good (if you like 3D ;-)


I know, that modern TVs can build a 3d-image from a normal TV-2d-image, but it does not work good in every program. Perhaps it can be try with any CPC game and see what happens .....

I'm pretty sure it will only do that on the HDMI input and even then it probably needs a very high refresh rate. I doubt it would accept a dual picture at 50Hz.

it's an LG D2343.

The tv I have seen has a mode where you manually switch into it.
Without switching, a display from a pc for example is not in 3d, when you do the switch, it becomes 3d.
So it may still be possible.

So, it will be possible using an emulator, but what about a real cpc???

Display 2 pictures side by side on the CPC screen, and put your glasses?

the tv takes the side by side pictures and turns them into an image where left eye is on even lines (or may be odd), and right eye is on the other lines.

The glasses then filter that so you see a 3d image.

So I could make it so the cpc draws 2 pictures side by side, but when the tv is switched into this mode, it must then display the image correctly for the glasses to work.

This last part is the problem...
Maybe I need to borrow the tv
It's owned by a guy in the office.

Is there a display unit in your local Dixons?

Thanks for the info.


I think it could be possible. You need an external adapter to convert the CPC signal to a VGA or HDMI signal for the monitor.


@all: I didn't understand at the beginning how the video signal should be, but here you can find a lot of examples:


3D's channel - YouTube


any example shows a video with two parts. If the TV is mixing it, then you get it 


P.D.: you will lose resolution, but it will be 3D ..... I think ....

two possible display methods:

side-by-side (left eye on left, right eye on right).
Here, horizontal resolution is half and vertical resolution is half too (because of the way the tv shows it).

other is to have 1 image at top and another at bottom, split in the middle.

here, horizontal resolution is not reduced, vertical resolution is half.

The effect is really good and frame rate is not reduced.

With this monitor the image does not flicker. The glasses have special lenses and are cheap.
