  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

2560x1440 standard?

The quality needs to be at least Bluray quality.

Blu-ray's encodes go through a lot of manual re-encoding, on a scene-by-scene basis, to achieve maximum quality, using offline encoders. Realtime encoders don't really stand a chance of achieving the same level of quality.

A couple of years ago I did a 4-way split screen demo showing the D5 source, Xbox Live, ATSC, and DirectTV from an episode of Lost. ATSC, with MPEG2, was so much better than what DirectTV was delivering with AVC. Part of the problem was that DirectTV was starting with the MPEG2 encode and then re-encoding. I am not sure how the quality of DirectTV is today. I will try and dig up the screen shots and post.
 
I mentioned it earlier in another thread:

QuadHD is 2x2y 1080p
QuadHD is 3x3y 720p
Display manufacturers have already QuadHD panels (some even 4K panels). Its just a question when first products hit market at reasonable price levels.

There are 30" 4K panels... So why stick with old fashioned 2560?

And 4K is not the end...

Do you have any links for someone interesting in learning more about this?

Axel, could you tell us more, I'm in the market for a 30 inch 4K (or bigger) panel? I've been hoping for an Imac with one, or for the others, but nothing.

As far as I was told its having a 12K horizontal resolution, but does not have the RGB matrix on. So they use it for medical display and create like 12 bit shades of gray using kind of dithering or similar approach. Thats how their other medical displays work.

I would expect a major vendor has booked the thinkable RGB panel exclusively for an upcoming 4K monitor. Whoever that is.

It will be a nice form factor to work in 4K. My 15.4" full HD DELL D800 notebook gives me that pixel density feeling all day since nearly 8 years now...

And this is just one quick example.

Cheers,
Axel
 
He, he Chimie,

They were one of the first to show and release a SHD display panel years ago. They were a manufacture of cheap panels and for many TV brands. I even wrote to them during the DIY cinema camera projects, to suggest another market for the displays, as digital cinema monitors for viewing and editing, to provide another reason for release. Nvidia was advocating SHD resolution standard also, but it did not happen, instead we got up to $100K 56 inch digital cinema panels n:( (the "n" was a mistake, but it looks good I'm claiming copyright on that one :) ).
 
Yep, I want one, you could put it on it's side and edit multiple 2560 screens }:) (I'll copyright that one as well ;) ) .

Well, after so many years of drought, maybe the 4K screens will come from Dell gateway and Apple, rather than the old tech 2560 screens. What do these people think that people were going to do with there 8Mp+ images. What they really need is 56 inch plus screens (with touch for editing posters). Lets see 30 inch is a quarter of a 60 inch screen, so 8K should be possible for Epic owners ;) .

The thing is that 4K has not been unsellable for a long time, even 8K is not unsellable now, even a low end professionals and specialist uses can replace 2+ full hd monitors and line up multiple images on the same screen. That could have sustained a market for a cheaper screen (cheap relative top $20K+ screens).

I've learned some interesting things though. According to a article on LCD screen technologies, the grey to grey response times quoted can be up to 50 times faster than the slowest response time. So, is the 25 ms response time of this IPS panels the slowest time, or anywhere near it? I notice that IPS response times can be woefully slow, so much you are going to miss certain noise and artifacts in the images, let alone motion and motion artifacting. Even if it is 25ms that is only 40 fps, OK for old cinema, but not when you should be looking at 50fps+ speed for TV and new cinema. Even the new computer panels (like viewsonic) are doign 1ms (*50 would be 50 ms, but to give it the benefit of the doubt *25) pity there are no 1/2ms screen ;) . This is insane, there should be rules to require accurate worse response times to be explicitly quoted, and response times in 3D and other modes (where they can restrict the range of brightness to boost response times).


Your honor, I cannot tell if my 100hz screen is a 100hz, because of all the blurring ;)
 
Here is a 56 inch SHD TV panel, notice they say that the color gamut is 100%, what were up to nearly 200% on a laser view now ;) . 100% response time to, what does that mean.

He, he, this is what I have been telling people they could do for a while cheap, what I have been planning to do for years, but they have been too busy listening to themselves as usual:

Sorry, wrong one, another technology I had been planning to develop, I thought that was a four fullhd projector to 4K image system instead.
