I just found my new computer display!
 
a 65" computer monitor is a little excessive :p (as is the 6K dollar price tag)


Looking forward to smaller 4K displays though
 
It is great that it was display port. All the sony 4k tvs are able to get HDMI 2.0 now through firmware update later this year. They must have used the hardware and were waiting for spec to be released. The problem with those other TVs are that they only hae hdmi. No video card out has it yet. I have a titan and I would hate to throw it away for updated HDMI 2.0 capabilities. Hopefully someone will come out with displayport to HDMI 2.0 capabilities, otherwise this is not going to change gaming soon.

I guess the people that care about this stuff upgrade enough that it wont make too much of an issue?
 
This is great news.

As far as I know this is the first TV to include a DisplayPort. I hope Panasonic starts a trend here, I think All UHD TVs should have a DisplayPort 1.2 port in addition to an HDMI 2.0.

I hope this will be the first monitor to support 4K 60p on DP 1.2 over a single stream. That would mean that DP1.2 controllers are finally ready to hit the market.

Due to signalling differences between DP and HDMI, we'll probably have to wait until DisplayPort 1.3 before any HDMI 2.0 to DP adapters become available.
 
Stunning...but I chuckled a little at "Intelligent Frame Creation" bit.

But Vega...surely 6 grand for a display is excessive even for you? :)

I presume yuo wouldn't give up your LightBoost displays for this but would keep them for gaming
 
While I'm not a fan of motion interpolation myself, that little nugget does confirm that the panel in the TV is actually capable of 4K 120Hz. Now all we need are the cabling standards to catch up. DP 1.3 I am looking at you.

It would be cool if the display could take 1080p 120Hz natively and just do simple dot doubling scaling to bring the resolution to 4K while maintaining 120Hz.
 
Impressive specs aside,

Is it Game Mode compatible, like Sony's Motionflow Impulse? Can you turn off interpolation during the scanning backlight?
What I am interested is; can it do scanning backlight with low lag, without interpolation?

Also scanning backlight Hz numbers are generally far away from actual motion blur reduction, as they are bound by inefficiencies, such as diffusion between adjacent backlight segments (on segments versus off segments). Strobe backlights tend to be vastly superior to scanning backlights (see article on BlurBusters, as well as article on TFTCentral). That said, significant motion blur reductions should be achievable, even if not proportionally all the way to what the "2000Hz" suggests (ala exaggerated contrast ratios) due to known inefficiencies in scanning backlights. Most scanning backlight modes are worthless for videogames since it is force-bundled with frame interpolation. I am wondering if there's a Game Mode compatible operation. There is a lot of existing scanning backlights (Panasonic, Samsung, etc) that have often approached ~100ms input lag (due to interpolation being enabled), so you may be stuck with worthless 60Hz during Game Mode. Only recently, nVidia LightBoost and Sony's Motionflow Impulse, have provided highly efficient CRT-like low-latency motion blur elimination, and if you go the plasma route, then the NeoPlasma panels used in certain past Panasonic TV's tend to stand out for more CRT-quality motion on plasmas.

Bottom line:
- Scanning backlight needs to allow an interpolation-free setting for low input lag. (usually a FAIL)
- Needs to be Game Mode compatible. (Sony's strobe backlight is the first to be)
- Motion blur elimination capabilities of scanning backlights are nearly always lower than strobe backlights.

Tests are needed by a highly game-knowledgeable reviewer.

Actually, a scanning backlight is similiar to a strobe backlight. Instead of strobing the whole backlight at once, it strobes parts of the screen at a time. It still reduces motion blur like a full-strobe backlight, just not as efficiently as a full-strobe backlight.

The million-dollar question is...
Is the scanning backlight in this model GAME MODE COMPATIBLE????
Usually, it isn't. This is a pre-requisite for getting the LightBoost-like effect with computers with low input lag.
 
Aint no such thing as too much for Vega.

I stopped reading and started drooling once i saw that it has a Displayport.
TV+displayport= me 6k poorer.
 
I guess I have to eat my words...I always figured some no-name Chinese manufacturer would be the first if not only one to put DP in a full-blown UHDTV (versus a dedicated monitor--that delineation still stands). And the $7k MSRP, considering it's also HDMI 2.0 compliant out of the box, isn't too shabby either. That said, my inner cynic's just waiting for some showstopper-class quirk to manifest when this thing actually gets out into the wild...
 
There is a ton of more information about the TV on Panasonic's Japan page if you know Japanese. I added the tv to my list and included links to those pages as well a link to the official spec sheet (in English):
Panasonic Viera TC-L65WT600

I couldn't find anything yet about color depth so I am assuming it is 8-bit but it would cool if it was 10-bit. That is not so far fetched since many 4k panels are 10-bit. I guess we'll have to wait and see for Vega to get his.

And now for the moneyshot:

I think I'm more excited for OLED, sounds more interesting right now since it seems most of the 4K TV's only really have the resolution going for them, nothing really special with the picture quality on those.
 
Well Sony and Panasonic both showed 4K OLED prototypes at CES 2013. Samsung just showed off a 4K OLED prototype at IFA 2013. So by the time OLEDs become affordable you'll probably be able to get both.

Yep, though I expect it will take at least 3-5 years before OLED gets the motion clarity equivalence of a good plasma (e.g. Kuro, NeoPlasma, etc)

I love the idea of OLED, and OLED has a better start than the early terrible LCD televisions, however, the motion blur department has a long way to go at the moment.

In a perfect world, we wouldn't have motion blur and we would have perfect colors/deep blacks. But I'll take great colors and plasma-like blacks with a bit of motion blur for now. If Plasma's could be brighter/had no chance of burn-in(it can still happen, even if it is rare, that thought will always be in the back of your head if you have a plasma), they would be perfect.

It can be quite sever. Every oled screen I've seen has quite bad blurring, especially from black to white. The IPS screen on my Lumia 920 is a lot faster than the amoled screen on my Galaxy S and brother's GS2.

And speaking of burn in... My GS had quite bad burn in before the screen changed. Also the "memory" in oled screen is annoying, especially when the brightness is low and you'd try to view solid colours.

Well to be fair, OLED can have very fast pixel speed. It's just that manufacturers are clueless and are using sample-and-hold 60Hz instead of quickly strobing them at higher refresh rates. OLED pixels can transition as fast as .01ms.
 
Well, if they can get it down to a 30'-39" in size I'd be interested. Anything bigger than 39" on a desk is going to kill your eyes over time IMO.

In theory, yes -- for PMOLED.
But, practically, definitely not for AMOLED.

In real life, the TFT transistor in an AMOLED is far, far slower than that -- just see the rise and fall curves in this graph. The rise and falls are almost a full millisecond long!

You need passive matrix OLED to bypass the TFT slowness -- ala PMOLED (available currently only in small sizes), not AMOLED (brighter, but not short-persistence friendly). Trimaster tries to solve this by using a rolling scan. Trimaster's is about half a screen height (so about 50% motion blur elimination, from 16.7ms sample-n-hold to 7.5ms). You can use a shorter-interval rolling scan. A scanning pass that turns on OLED pixels that's closely followed a few pixels rows behind, to turn off OLED pixels that were turned on), and potentially achieve about ~1ms in an AMOLED before you start getting major problems caused by the rise/fall. You may run into at LightBoost-length pulses (1.4ms to 2.4ms) due to the really slow rise/falls of the Trimaster OLED.

The problem is solvable, but it's not as simple as the "OLED pixels can transition in 0.01ms" myth, due to all the various vactors. Right now, AMOLED is the only practical way to create large OLED screens, since PMOLED at such large sizes are impractical, since scanning such a display one-pixel at a time, would require a PMOLED that is capable of shining it pixels a thousand times brighter (for one-scanline-at-a-time illumination) or a couple million of times brighter (for one-pixel-at-a-time illumination) to gain the equivalent brightness of an AMOLED. Obviously, such brightness levels are impractical for a large-format high-def PMOLED. So we're stuck with AMOLED, which forces fully millisecond-long TFT transition times upon ourselves. However, a response-time-accelerated rolling-scan AMOLED can have sub-millisecond transition times; just definitely not all the way to 0.01. 0.01ms transition time is useless if it's 16.7ms of persistence; we don't see transition times that's far less than the persistence time (sample-and-hold time). Even if the transition time sharpens to 0.01 transition time (time to turn on -- not the strobe length, the shortest time for a good off-on-off cycle) the brightness levels needed for 0.01ms strobe length still requires OLED's about a thousand times brighter than they are today.

Yes, we will eventually manage to get better-than-LightBoost-clarity OLED, but we'll not be able to get the 0.01ms (for on-to-off cycle) OLED in large-format sizes. Realistically, it falls to a few tenths of a millisecond for transition time, allowing clean 1ms-or-less off-on-off cycle times (<1ms persistence). Unfortunately, the OLED 0.01ms "persistence" (not "transition") dream is a myth when we run into such practicalities.

Ya, I guess I didn't realize that OLED was still having such brightness issues, and they use sample-and-hold just because you need OLED pixels to be lit that long just to give decent brightness. Amazing how bright phosphorus would emit light when being hit for such short duration with electronics in CRT's and how we don't have anything to keep up with that.

Actually, I'd love to see progress on Sony's "Crystal LED", direct-view LED setup. Getting small size would be it's largest issue but it would be the only tech to have awesome picture quality and at the same time stellar motion clarity since CRT's.
 
OLED without strobing/black frame insertion etc is no better than a fast TN LCD. Our eyes need a blanking period at low fps, or super high 1000fps+ to remove visible motion blur. The camera may see no blur at 1/250th exposure, but our eyes don't work in individual frames.

I dunno about that at all. I've been using my 50" Seiki since May and I have experienced no problems so far. I'd even go so far as to say I experience fewer headaches related to eyestrain.

Ok, I've sent email to Raymond. He is a highly respected person and knows what he is talking about, but needs a minor modification of the terminology, in my opinion -- since the LG OLED has more motion blur than a plasma display. It's already confirmed by several sources.

Hello Raymond:

There is a minor error in one of your articles.
The phraseology "motion blur" should be changed to "transition time" or "ghosting":
http://www.displaymate.com/LG_OLED_TV_ShootOut_1.htm#Response_time

Although the transition time is excellent, the LG OLED still has motion blur caused by sample-and-hold, especially when we're doing fast motions (e.g. window dragging, scrolling, etc). There is still some sample-and-hold motion blur on the OLED's. Also, "ghosting" (remnants from previous refreshes) is the word that should be ideally used instead of "motion blur" (includes sample-and-hold, which the OLD still has).

Response time (based on MPRT measurement -- Motion Picture Response Time) is different from transition time (0.1ms). Several OLED's with ~0.1ms transitions actually have at least 8ms-16ms of sample-and-hold, creating an high MPRT measurement from things like MotionMaster and other MPRT measurement cameras.

[HDGuru] said the LG55EA9800 has motion blur as bad as a 60Hz TV (120Hz TV). This is seen in moving resolution test patterns. We're not talking about the ghosting (correctly described and photographed by you) but the sample-and-hold motion blur.

For example, try viewing this motion animation on the OLED:
http://www.testufo.com/#test=eyetracking

Also, I have found a way to do inexpensive pursuit camera, using existing consumer cameras:
http://www.blurbusters.com/motion-tests/pursuit-camera/
Only a $150 low-friction camera rail and a consumer camera is now needed, because of a new technique of verifying tracking accuracy.

Sincerely,
Mark Rejhon

I have no knocks on Raymond and I highly respect him & his article is quite correct (when reading his "motion blur" terminology as "ghosting"). There is definitely zero ghosting on an OLED -- zero bleed between refreshes. But for writing to the (gradually-becoming-increasingly-educated) public, he will need to carefully make sure the phraseology now accomodates the sample-and-hold motion blur, which is a different cause of motion blur than the panel's own ghosting (LCD refreshes bleeding between refreshes).

Is it sitting on your desk where you are closer than 3 ft? I'm just thinking its like that old addage Mothers used to warn us if you sit too close to a tv for a long time its not good for you. Then again maybe mom was wrong? :D

Mostly that was because of radiation produced by early TV's.

As the other poster said, it was more to do with the radiation from the older TV CRTs than eyestrain.

I sit about 3.5ft away and it works well for me but I do understand it may not work for someone else...
 
Look's like these are starting to ship. REALLY curious as to the input lag numbers on these. Just may pick one up in Nov to test once I get back from school.
 
I really hope that the Panasonic TC-L65WT600 is the first display to support 4K 60p over single stream.

It looks like it will be the first display to support 4K 60p over HDMI 2.0. As far as I know, the firmware update for the Sony 4K TVs to enable HDMI 2.0 is not yet available.

GPU vendors haven't made a peep about HDMI 2.0 4K 60p support yet though.
 
I am trying to hunt down the users manual on this thing to check for game modes etc but can't find it.
 
Yeah there is a monitor mode specifically for low latency usage. No mention of what the actual latency is but they are trying to promote its use for pc gaming.

TwIT1bz.jpg
 
I also wondering about the Input Lag on this panel. I have a Sony XBR-900a 65" 4k set and it is great, but the Display Port is what is attracting me to the Panasonic...but no mention of Game Mode and Input Lag has me wondering if I should just keep the Sony. Sony will be updating the HDMI to 2.0 via Firmware, but my gaming rig (2xTitans) don't have HDMI 2.0, nor does any GPU at this time, so the only way to get 2160p/60fps is through the Display Port.

Any tech heads can answer this. When Sony updates the HDMI ports to HDMI 2.0, what would stop someone from using a Display Port to HDMI converter and having the GPU send the 2160p/60fps through the display port, into the converter and then to the TV? HDMI 2.0 allows the use of current cables, albeit recent ones. I am not tech-bound enough to know if an adapter would work or not.

I read a bunch of the Japanese stuff, but all I could find is that it says you can use it for PC gaming. Haven't seen anything that talks about a game mode with lower latency etc..

Considering how many years it took for MST hubs to come out, it could be a very long time before a DP 1.2 to HDMI 2.0 converter comes out.
 
Yea easiest solution for HDMI 2.0 compatibility is to sell your old gpu for a newer model when the time comes.
