4k TV arrives at MacDocs

I've been following HD since 1982 ....scored a stupid good deal on a upper end OLED screen

Blacks are spectacular as is the image. The combination is astonishing

$2 a month more to stream 4k from NetFlix. There is a reasonable selection and the TV upscales HD as well.

My main goal was to get it as a monitor for the Retina laptop and my full rez pics look very good on it. I can have 4 working sections all at high quality .. happy camper. :dance:

When I consider what a small OLED cost just a couple years ago ....55" is astounding.....and so thin.

Image

Decent sound system in as well. The LG is just plugged in standalone ....it hooks into our wifi network and streams the 4k in.
Count me impressed.
I just switch source to use it with the computer and can also stream Netflix, Amazon etc via that route but not at 4k.

:popcorn: movie weekend :mrgreen:

I have a Dell 4k monitor ......that's a different aspect. Streaming 4k is awesomely difficult technology.
As mentioned tho .....this is an OLED screen....

really truly black. For me - the OLED is really the big deal tho the streaming 4k is excellent....prepare for lift off.

Indeed, the tech been around for some time now but it was too expensive. It consumes more energy than LED LCD tho I think, at last when set to bright.

I new OLED was coming for big screens, I didn't know it was here at less than insane costs. The amazing quality of cell phones left me salivating for one of these for a long time. The flexible screens will be revolutionary when they get good and rugged enough. What I really hope to be around for is for imagery to either be generated on contacts and then direct stimulation of the retina or deeper layers. Very cool.

I tell you watching a 4k stream show about cooking is a rewarding experience. I tried watching a series on the Retina laptop....just doesn't cut it any more.

So many of my content creator clients are shooting in 4 and 5k now and the pay off is coming. Even the Pro-sumer 4k cameras are vry accessible. I think we will now start to use that overbuild of fibre.

Chef's Table streaming in 4k on Netflix is a good series on food and preparation and lovely eye candy.

I look forward to what they'll be doing with the head-mounted displays / video goggles in the coming years.
When it comes to stereoscopy ("3D") these have an advantage over television and cinema screens, which must make use of polarised lenses. Imperfections in the polarisation are revealed as "ghosting" of the 3D image (faint blurring and double-imaging).
There's no such ghosting when it comes to the head-mounted displays, because the left-eye and right-eye views are projected straight into each eye respectively, eliminating the need for polarised lenses.
Essentially, the head-mounted displays are high-tech video versions of the old View-MasterTM toys that delivered flawless (albeit completely still) '3D' as far back as the 1960s...

The future looks exciting.

4K - so you can sit closer to your widescreen & get the same effective resolution as I do from my standard HD, from a sensible viewing distance. I'm convinced.

If you saw your photos on 1:1 OLED you'd change your tune right quick.

"Effective resolution" ...is that the cop out term for lack of detail ?? :whistle:

Image

Image

And that's HD as as a base let alone SD which is simply pathetic these days.

There are all the people that have upoaded their photos at lower resolutions that will be mightly disappointed down the road.

In addition - the much higher dynamic range and pure blacks make it very hard to resist.

The human eye can resolve no more than 300 pixels per inch, and that's close up. At normal viewing distances, you certainly can't resolve the greater detail from a 4k screen over a HD one. Like I said, if you're close to the screen, you'll notice the greater resolution.

As for the dynamic range etc., I'd grant you that that is an issue worth considering

It's not all about "TV" ....4k resolutions are coming to all screens.
Viewing media content is more and more a personal experience, up close and personal, and being able to resolve 4k video streams on desktop monitors and laptop monitors - along with the enhanced colour and contrast it ups the game substantially.

If your camera - video or still can do 4k ....then these are the screens needed to fully resolve that additional detail.

8k will be for very large spaces ( arenas eetc ). 4k useful even now and of course the technology is going spill over into VR where it needs incredible pixel density to maintain the illusion in very near field viewing.

Who the fuck sits in an armchair and watches TV any more any ways?? :D

I'm actually more excited by the OLED tech with it's infinite black and colour advantages than the additional pixels.

This site perhaps gives an idea of the range in products that are in the midst of 4k migration including cameras

I mean really..... right out of the future...

Olympus is also claiming that the TG-Tracker offers integrated waterproofing down to 100 feet, dustproofing, and resistance to as many as 220 pounds of crushing force. On the other hand, the little camera is designed to be shock-proof against falls of no more than 7 feet, which goes slightly against its reputed ruggedness. However, cold temperature resistance is set at 14 degrees Fahrenheit, making this a great camera for winter users.

This doesn't address the worst problem with all 3D so far, and that is that the image is at a fixed distance, so the eyes cross as something comes closer, your brain want to focus closer, but that doesn't work, the image distance is fixed, and this gives many headaches.

That's a very cool looking camera, and could easily sub for a futuristic weapon. Why the disparaging of a 7 ft drop test in the quoted bit? That is a tough standard if it's to a hard surface like a concrete floor, the g-forces can get huge and can be devastating to corners and joints and sticky outie bits,

Is LG the top manufacturer of big OLED screens? There's often 1 company that has some new tech down better than everyone else for a while. I was just looking for a large-screen book reader, I don't like reading off tablets and prefer the E-ink screens, or I should say my eyes prefer them. So, I thought by now there'd be some reasonably cheap ones to be had in the 10+ inch size, and no! There seems to be a stumbling block much past 6 inches and prices ramp up considerably. I love this thing and want one but over $895? Can't justify and fuck, it was 'only' in the high $700s when I saw it only 3 weeks ago. It's a SONY Digital Paper DPT-S1, it's Japanese import with Japanese OS, 8 1/2 x 11, but I'd love it if they made one for here and a lot less $$$ Being able to read most pages at normal size without reformatting would be marvelous.

What's the visual acuity of a human eye, something like 1 arc minute (i.e. 1/60th of a degree) right? At least a quick wiki read lead me to that number. Seems reasonable. So for it to make sense to upgrade to a 4K screen beyond HD your screen would have to take up more than 32 degrees of horizontal view. An equal or smaller field of view would make the difference indistinguishable. I rather doubt many people would benefit from 4k, probably another marketing gimmick, like 3d. Contrast (esp. black and HDR) and colour fidelity are far more noticeable than simply adding resolution.

[edit] Can anyone explain to me why curving a tv is a pro? I don't understand it. For a PC monitor it can make sense as the user sits in 1 spot, but for a TV - which is used in group sessions a lot - that distortion would be rather annoying for most viewers no? Or is this not the case in practice?

There is no benefit to a curve aside from a bit of added strength and showing that it can be done. ( OLED is flexible ).

Um 32 degrees FOV is nothing ...you don't get anywhere near a cinematic experience. immersive wants 60 degrees and up - and again ....group media watching is simply not where is is going. Hell my FOV on the Retina laptop is well over 30 degrees when I'm watching media.

Flap all you want ....4k is mainstream...and OLED is almost there.

Contrast (esp. black and HDR) and colour fidelity are far more noticeable than simply adding resolution.

only to a point...you cannot add information ....the additional pixels also carry information regarding colour gradients and light.dark. Detail is not the only win. With 10 bit colour on the OLED and other screens, you have 4 times the pixels to produce the colour.
The human eye can see 10 million colours.

3D was a gimmick.....4k is not by any means and OLED is simply icing on the cake.

You're sitting around 2 meters from your screen? With a larger distance 4k simply forms no benefit over 55" 2k / HD screens. To me that distance would be quite unpleasant for a longer viewing time. I'd wager in general use most people wouldn't even be able to see the difference between a 720p and 1080p video in practice, especially given the heavy compression online media offers. A low res high bitrate video can be quite a match to high res mediocre bitrate videos.

I'm no where near 2 meters from my screen ...I work 30" from the 55" OLED and 12" from my Retina screen.

Cinema FOV requires people sit far closer than they are used to. I've been dealing with HD since 1982 when I saw a closed circuit version from Panasonic - you could look at the geisha and the big screen TV at the same time at the same distance - it was analogue and it was spectacular.

I had a 50" Mitsubishi in 1984 when I watched the Apple launch commercial ....I was sitting about 3' away at the end of the bed.

I've always hovered around 40" to 50" as the best balance of near field image quality and cost. The 55" is basically 4 x 2k monitors for my use....I usually run 2 x 27" 2k plus the Retina laptop.

It's the colour and dynamic range of the images in addition to the high pixel count that makes it spectacular.

The calculator here gives. 1.6 m as maximum distance for full resolution on the 55"
http://ca.rtings.com/tv/reviews/by-size ... lationship
...I'm about 1 meter from the corners and a bit less than a meter at the closest and it is superb.
Image
this sits about 24" beyond the laptop screen.

I'm seeing detail in my photos I've only seen on the 5K 27" iMac.

Media viewing is not the sit home with the family gathered round watching Bonanza anymore.

Gamers are immersed, VR will get more immersive yet.

4k streaming is not yet perfect but at times can be spectacular when it all comes together. OLED tho is a huge step forward in image reproduction.

I work on the 55" OLED then switch over to Netflix streaming while I'm still working on the laptop...nice set up for me.

This is how small a Pro level 4k camera rig is. Gone Girl was shot on this.

Image

and many including my clients are shooting on these - other clients on RED. ( above )

Ah, yes with that distance it does make sense :thumbup: And I agree with the colours and contrast, (although only having seen the screen a few times in a store) it looked quite spectacular indeed.
