Sony unveils pro 4k OLED monitors

it's exactly because a "retina" designation, ie pixels indescernible for a certain diagonal size at a certain distance (which can be relatively easily calculated, and apple neither can or has to specify it for every diagonal screen size and viewing distance scenario) is very valid and meaningful that someone can gauge how a 137 ppi 30" monitor can come close to looking as good as a 300 ppi phone.

Please don't confuse people any more solely because you dont like a designation because apple came up with it. Originally someone asked you if a 4k 30' monitor is retina and you replied no. That's just confusing people for the sake of having an axe to grind with who came up with the designation. The answer should have been yes.

As I said before a retina moniker is far more useful than the 1080p, 720p, 4k etc. garbage that tv manufacturers have been throwing around the past few years which are far more vague. "Is it retina?" translates to a simple question with a simple answer: Will I be able to tell pixels apart, yes or no? It doesn't imply that a monitor being high enough ppi, or retina, that other quality markers (underlying display tech, contrast, saturation, pixel substructure etc.) should be ignored and that high ppi, or retina, is the be all and end all of monitor quality. It's not, but it's a very important factor too, especially so for computer monitors.

And it's much less confusing than telling someone this 7" monitor is 1080p, and that 27" inch one is also 1080p, whereby your average Joe will go, ok, so they are equally good in that respect. No they are not, one packs enough ppi for 7" the other one doesn't and lets the pixel structure appear.I really hope someone other than apple had come up with a "retina" designation because then some people would have less resistance to use what is a very meaningful, and very apt term that gives immediate feedback on what to expect from a monitor in one particular quality marker.

Why can't these companies take one step at a time? 4K *and* OLED technology, seriously? How about starting with some relatively affordable 1080p OLED displays first?
 
these monitors can be considered as retina displays, right??

It depends on how close you are. If you are at least 20" from the 30" display then yes.

A 30" 4096x2160 display (154 PPI) at 3.8' viewing distance (typical for a TV) gives a pixel-per-degree (PPD) of 3.8*12*154*2*tan(pi/360) = 123 PPD. At one foot away, the PPD goes down to 32 PPD. But if you are 21" away or further the PPD is greater than an iPhone 5, which has a PPD of 57. If you sit at least 20" away then the display is "retina", since the PPD will be 53 or higher, the minimum according to Steve Jobs

A 56" 3840x2160 display (77 DPI) at 6.8' viewing distance gives a pixel-per-degree (PPD) of 6.8*12*77*2*tan(pi/360) = 110 PPD.

The formula I used for PPD is:

PPD = viewDist * PPI * 2 * tan(pi/360)

Would be a dream...assuming also resolution of the burn-in issue...

There are already 1080p (PVM-2541) screens in the Sony lineup the 4K ones are supposed to belong to. No steps were left out.

Just because the average consumer is an idiot and doesn't realize that "retina" is a completely nebulous marketing term, has no bearing on the usefulness to the informed buyers here, your argument has no bearing. I'm sorry, if a consumer is stupid enough that they can't discern image quality unless it is distilled into a single word...I just don't know what to say. Obviously, retina is a meaningless word anyway. Image quality is based on more than PPI when you're guaging a big-screen, it is not judged by the same criteria as a smart phone due to viewing distance - although you already realize this I believe.

Finally, there will never be a non apple product referred to as retina. IT IS A TRADE-MARKED MARKETING TERM AND NOTHING ELSE. It's a great term for the idiocy of apple fanboys, but it a meaningless term in the grand scheme of things for reasons already mentioned.

No need to yell. Sure it is a trademark term, but it has meaning, one that lets them convey an idea in one catchy word. Thus you have people waiting for the Retina iPad Mini, or Retina iMacs.

Obviously non-Apple products won't be marketed as "Retina", but people want to know if it will be Retina Equivalent. What they are asking is: Will the pixels be invisible at normal viewing distances? The final simple formula from the initial wave of debate about this boils down to:

3438/ppi = Retina Distance


3438/326 = 10.5 Inches (Retina iPhone 4 that started the marketing term).
3438/264= 13 Inches (Retina iPad).
3438/220= 15.6 Inches (Retina Macbook).
3438/154= 22.3 inches ( the sony 30" 4K OLED).

So the Sony 4K OLED would be Retina Equivalent, if you used it more than 22" from your eyes. Which I think most people would, as that is extremely close for a 30" monitor. It would look insanely sharp when displaying full resolution content.

But that is mostly fantasy calculation as this is likely priced around $20 000, and it is not a computer monitor, it is a Video Monitor, meant for working on movie/TV production.

OLED still has the big problem of burn-in that will keep it off the computer desktop indefinitely.
 
Guys an update on this 30" 4k OLED, linky below:

SONY 4K OLED

The 30" panel is produced the same Japanese fab that produces Sony's current OLED panels (the 7.4", 16.5" and 24.5" panels used in Sony's professional monitors). This explains why the resolution of the 30" panel (4096x2160) is different than the 56" one (3840x2160) as the Oxide-TFT backplane of the 56" panel is made by AUO, not Sony. Both panels however use Sony's Super Top Emission technology.

Our source at Sony confirms that they plan to launch the first 30" 4K OLED monitor next year - in fact they plan to do so by April 2014.

Regarding those enhanced 16.5" and 24.5" OLEDs for the "A" Series monitors, our source says that the improvements were achieved by a new architecture - Sony redesigned the pixel construction and this enabled a major improvement in viewing angles and a greatly reduced color shift.[/QUOTE
