With all the hype with 3D i was wondering is it not possible that we can get a relatively good 2D setup and if and when 3D becomes important, all we would need to do is strap a nvidia setup with a PC to our 2D TV and presto 3D. Or am i missing a point?:confused:
 
You're missing the fact that for 3D, depending on the form of stereoscopy implemented, a TV might need to have a very high refresh rate, as well as a way to polarise alternate frames.

If you ask me, by the time 3D becomes "important", a TV you buy now will require replacement.
 
Yes true, but assuming you buy something now that is compatible with something like the nvidia 3d vision, whats stopping someone from using that to create a 3D setup? Is there a technical limitation to it such as not compatible with 3D bluray discs?
 
And then there's the question about a so called "HD Monitor"... isn't any decent LCD monitor HD by default? Or did I miss that too?

You definitely missed that. An "HD" monitor high a higher resolution than a normal one. Not all LCD monitors are HD by default. Unless I'm misunderstanding the question.

An 22" monitor's 1600 x 1050 resolution is HD, isn't it?
 
I was under the impression that HD also referred to the aspect ratio of 16:9 - therefore a screen res of 1600 x 900 would be HD. Am I right/wrong?
 
High-definition television (or HDTV, or just HD) refers to video having resolution substantially higher than traditional television systems (standard-definition TV, or SDTV, or SD). HD has one or two million pixels per frame, roughly five times that of SD

Wiki.
 
Full HD wiki

1080p is the shorthand identification for a category of HDTV video modes. The number 1080 represents 1,080 lines of vertical resolution (1,080 horizontal scan lines),[1] while the letter p stands for progressive scan (meaning the image is not interlaced). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080. The frame rate can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 progressive frames per second, or 1080i60, meaning 60 interlaced fields per second.

Nope, HD is 1920 x 1080, so the 1600x1050 monitor is not true HD.

as for 3D, LCD monitors work by polarising all light in one direction and then using polarised filters to emit only the right color of light, this completely elimates the possibility of using a traditional LCD for modern polarised 3D video as used in Blueray 3D etc, no matter how high the refresh rate.

Full HD is 1920x1080, or 1080p (1080 vertical lines). HD is 720p (720 vertical lines), usually ±1366x768.

HD = 16:9 aspect/dimensions ratio. Most 22" LCDs are 16:10, so they will display HD without problems other than there being black bars at the top and bottom to reduce the "height" of the screen.

True, but even by that definition a 1600x1050 resolution does not fall whithin the HD specs, to display either Full HD, or Standard HD on the screen will require the image to be rescaled the result will not be a pixel for pixel display, as a result pixel bleed and crossover will result in a loss of quality. i.e. the screen needs to spread 1366 virtual pixels accross the screens 1600 real pixels. even an old 14" 640x480 CRT display can display a scaled HD image, that does not make it HD though. neither does a screens aspect ratio,a 16:10 or 16:9 wide screen is not HD unless it also has the corrrect resolution.
 
I understood the question like this :

May I buy a 50" Full HD (1920 x 1080) 16:9 LCD TV with 120hz refresh 2D TV now for R25,000.00 - and just add 'something' at a later stage to make 3D - since it forefills some requirements?

Could be wrong though - and dunno the answer :/

I guess this got a little off topic, as I said earlier though the 2D and 3D display technologies are not compatible.

It will still display as many pixels as a true HD aspect ratio screen would.

In the case of 16:9 full HD (1920x1080) on a 16:10 full HD screen (1920x1200), the same amount of pixels just over a smaller area.

Ah - missed the second part ...

Thanks
