Nothing but
lack of any foresight.
AFAIK there are no technical barriers to practically achieve 340 MHz clock defined in the HDMI 1.3/1.4 standards;
So you agree with my initial statement that
if they really wanted, they could have created such a chip by the time v1.4a was standardized and they could have made the 1080p60 3D mode a mandatory mode, right?
cybereality wrote:Yeah, but if you want to use it for gaming, HDMI 1.4 maxes out at 1280x720. So the TVs resolution is still higher than the source material.
That doesn't matter, the thing that personally bugs me is the pixellated picture. I guess I'm too sensitive, and the pixels of the plasma with such size are too big for me (in the case of 1366x768 native resolution for 50" screen that we discussed).
The resolution of the content is different story - with lower rez signal you lose sharpness, but the picture doesn't get pixellated (if you have high display native resolution), I hope you understand what I'm trying to explain.

Projectors are different story, you can see the individual projected pixels much harder (even if it has lower native resolution).

Because the separation is relatively low, and the director smartly avoids high contrast scenes.
Chiefwinston wrote:However, gaming in stereo has minor ghosting issues. Some games are completely ghost free. Others well- lets just say its the games stereo software thats the problem. I'm sure of it.
It's not the software - just crank up the separation and it's a ghosting fest once again

. Still better than other 3D techs, but it's nowhere near perfect. Once you lower it to decent level - the crosstalk almost disappears (a friend of mine has a VT20E, I know that form him).

I think you are talking about signal, not native resolution, see my answer to
cybereality. If you're talking about the native rez - then in both cases it will be intolerable for me

I also am a plasma fan, but I think black levels are much more important in 2D viewing. In 3D, the glasses block enough light to compensate. The advantage the PDP tech has over LCD is the fast response time (low phosphorus lag), leaving less trails and, therefore, leads to less crosstalk. But I still hope for good enough HMDs (which have absolutely zero ghosting/crosstalk) in the (near) future (like that Sony 720p OLED prototype
Silversurfer first wrote about for example).
Chiefwinston wrote:And finally, 720P is more suited for 50" and less. Above this and you'll most definately want 1080p60.
I think 1366x768 native resolution is acceptable for up to 32-37" TVs, not more. As I said, the perception is extremely individual. If you're talking about the signal now - then yes, I agree, I guess 720p is bearable for 1080p TVs, up to 50".

1. eye is more sensitive to luma (brightness) than contrast (blacks), plasma can't compete in 3d brightness department, white will be always way off, and going to ghost because of phosphor decay*
I think the human eye is more sensitive to luma (brightness levels - the whole scale (including the black level)) that to chroma (color) - that's why all modern compression algorithms use 1/4 resolution for the chroma channel
![Wink ;)](./images/smilies/icon_e_wink.gif)
(look for 4:2:0 or YV12). And FYI, when you adjust the "contrast" setting of your display you actually adjust the maximum brightness level, and when you adjust the "brightness" setting, you adjust the minimum brightness level (the black level), as crazy as it sounds (I learned that just few months ago myself

).

I guess you're talking about projectors as well. Once again, I think it's pretty individual. I, for example, think that 2K DLP projectors (or whatever they are using) in IMAX theaters (or at least in the one in my city) are not enough for a screen that big (and even for smaller ones) - you
can't see the individual pixels, but the picture is blurry ass hell.
