New Samsung 4k for everyone.

Saw an ad for their new TV's during a commercial break last night. I contacted the company that announced a DP 1.3 to HDMI 2.0 adapter at CES and they said it won't be available for a long time. :(

We know that on paper Samsung perfectly supports. But due to various problems in the past this has to be verified by independent tests. As well as measuring the input lag and looking for presence of artefacts related to colors, fast movements and all kind of unpredictable things.

Wow, I had no idea they made this full manual available. So not only does it do full RGB and YCbCr 4:4:4, it's also 10 and 12-bit capable for movies and other upscaled content. With 4k24p support, that must look incredibly good for blu-ray playback!
I'm sifting through the manual now, found a couple lines of interest. It has bluetooth for wireless audio streaming, game mode, and full BT controller support.
No 120hz modes appear in the tables, but who knows what we'll be able to hack it up to :cool:

It definitely supports 4096x2160/4:4:4, on the resolution table (not the colorspace one you posted) there's the same asterisk that relates to the JU6500/6700. "For the 6 series models or lower, make sure to connect to the HDMI IN (STB/DVI) port of the TV."

All that remains for me is an input latency test, and I'll pull the trigger on a 48"!

Ah I see, good to know. I'm not in the market for it due to the non-Displayport portion of the monitor, but came across the sheet and was hoping it might help people out. Hopefully it does truly support it, looks like an awesome monitor and the curve looks great!
 
Show me square pixels and this will be purchased along with a couple 980s!

So the 48" JU6700 Curved supports 4:4:4 chroma ?
Click to expand...

The manual makes explicit provisions for the 6xxx series on both 4:4:4 and 4k60, for PC input. They wouldn't add this if it wasn't true, and the 6700 is the highest model in that series.
Unless the 6500 is some freak panel, it should support it as well.
 
Looking better! Glad there are more 4ks getting released now. :) Hope to get one next year!
 
I wonder if this set is at Best Buy .........

temped to get 2 x 960's and this set
 
Wow, lot of decisions here if these can really do 4:4:4...40" versus 48", and, curved or non-curved for either size.

Anyone actually see or try a curved display for PC use? Did it add or detract from a typical PC desktop experience?

Am thinking that a 48" curved model might make a tight desktop view distance of say 3 or 4 feet more tolerable

I went to my BB yesterday and they only had the JU9000 on display. One of the sales were quite upfront with me and basically told me they need to get rid of last year models before they are willing to put up the new models for display. He won't even give me a guessimate on when they will do put up the new models. :p

Samsung live chat rep told me that they were going to be in stores by the end of the month. I don't think BB holds onto outdated inventory, I think they just discount it until it sells. I bought a 60" sharp aquos for $600+tax from BB in 2012 because they were phasing them out in favor of the "smart" version and needed to make room.
 
Could anyone tell me how to get 120 Hz refresh on my 55 inch screen. It also supports all the fancy shits you guys are referring to in JU series. My panel is HU9000 last year's model.

Do I need HDMI 2.0 for that? Will my 970s support it?

There are some user reports about the 34" flat vs. curved monitors and various reviews. In general people like curved more, perhaps except highe-end professional photographyc work.

I think it is better to have smaller display at closer range than bigger display at longer. So 40" should feel better.

Non-square pixels of 40" Philips turned out to be non-issue in practice. Instead of 980s consider Titan X :).
 
This may seem OT, but it is related to me possibly purchasing the 40" 6700 to replace one of my monitors. What is the maximum length of HDMI 2.0 cable? I ask as I have my computer in my closet and would need a long cable run (40') to make this work (I have a single 980).

If that doesn't work, I would consider moving my computer out of the closet, but would prefer to keep the heat in there (temperature controlled heat exhaust fan and closet is sound proofed).

Thanks
 
40' sata is a bit long.
The timings would be skewed and wave edges would perhaps see too much distortion, further skewing timing and data integrity.
But you never know :) I havent got time to check the sata spec to see what it will allow.
A good quality copper might give a working result.
......

He said HDMI not SATA, oops :)

Same manual page in the old 6900, and it still never worked for 4:4:4. Wait for someone to actually test this.

Perfect, that is just what I wanted to see. Was worried that the curve creates a distortion where games appear warped on the edges. Thanks wirk.

If one takes typical length there is no difference between the HDMI and HDMI 2.0. The problem is how far this 'no difference' reaches, maybe 40´is not yet a problem . It thus would not be unreasonable to try good cable of 40' length.

If you are talking about this year model there was no time yet for testing. Also, models in the same range but different sizes have the same electronics, results should be the same. Look for e.g. 55".
 
I currently have a Dell 30" U3011. I'm thinking of buying the flat JU7100. I cant decide over the 50" or 40" though. I web browse at my desk, game 5-6ft away with a controller hooked to my PC, and watch movies 5-6ft away. Is 50" too big for a desktop? Would it make the PPI too low?

If I decided to play games at 1080p do you think it would support 120hz? It's a 120hz TV, but I'm not sure.

I put an older 50" LCD on my desk today to simulate what a possible 48" would be like as a PC monitor, distance of approximately 4 feet. Currently use a Dell 30".

Basically that is one tall bitch. Like say for the top of your web browser, the tabs, looking allllllllll the way up there is definitely like a cure for "cell phone neck" lol.

But, it's amazing how I got used to it, after initially thinking "yeah no way, damn..." after an hour of forcing myself to see what it was like it wound up being ok.

Still though, I might wind up getting a desk arm for the 48" curved model if I do decide on it, simply to lower it another two inches by removing the stand.
 
They have the 40JU6700 in stock at Paul's TV (at least they're selling it on Amazon). Their retail locations are in Jordan's Furniture, which is right down the street from me. I can go in there and check out if they have them @ their B&M, but how would I test it for 4:4:4 support?

Yes, but the distance to the monitor is big. Would not be it more comfortable to have something like 40" at a smaller distance?

It is not that straightforward. You need to have computer with the HDMI 2.0 output, practically with a GTX 9xx card. Then you can just display test pic and see.
There are also other test pics for this.

I realize that, it was more a rhetorical question. It's not feasible for me to bring a tower with a 970 into a retail location. However I might be able to test a flash drive with a test picture. At least we'll know if it supports 4:4:4 over USB. If that works, then HDMI 2.0 should work as well (I realize it doesn't always work the other way).
 
I have purchased UN48JU7500 (Version TS01) from Fry's in Austin today. I can confirm it does 4-4-4 chroma at 4k 60p.

I had to set HDMI UHD color (connected to HDMI 1). Set the input name to PC and change input type to PC. Only then I got the 4-4-4 chroma.

Here are the pictures I took with my phone (does not reflect monitor picture quality as lighting was low and its a crappy phone camera. Its just to confirm 4-4-4. The moire patterns are not seen in person but only a camera artifact). Click on pictures to see the full sized versions.

http://imgur.com/JsJMin3,Rst4hNq,JVKTWBe,InVUndD,mGGBncB,V6vUNIs,YyCIutU,TBh9hEn,LqBW06P,knFSjwY

This is connected to GTX980 SLI

The TV suffers from the same shadowing issues as Benq BL3200PT so it is almost certainly a VA panel. Its not as bad as the BL3200PT. The picture #9 above shows the problem. The shadowing is vertical in this monitor (bl3200pt is horizontal). The background should be uniformly brown but you see two vertical lighter areas to either side of the purple. Those lighter areas move as you move the window with purple box.

Also 4-4-4 chroma only works at the following refresh rates at 4k:

60, 59, 30, 29 Hz

4-4-4 chroma fails in the following refresh rates at 4k:

50, 25, 24, 23

I tried and the monitor absolutely refuses to be overclocked in any way. Trying even 61hz refresh fails. This also happens at lower resolutions so it cannot go beyond 60z on 1080p (so if you were hoping for 120hz 1080p forget it. Tried it and it does not work). Scaling on 1080p looks very good.

I did not notice any lag issues but I have not done any tests beyond playing some 3d games.

The monitor has glossy mirror finish which is not so good. Expect to look at mirrored fatter version of yourself in dark scenes (this even with fairly low room lighting levels). After using it for a few hours this is definitely an issue

The curved screen is definitely preferable to flat (to me anyway). I have my previous flat BL3200PT next to it and I much prefer the curved monitor (in fact for a monitor at 2 feet viewing distance the curve could have been much higher).

48inch is overkill for just general desktop applications but its fantastic for gaming. My eyes are at just over 2 feet from the monitor (bit more then arms length). The horizontal size is perfect. Vertically the monitor is a bit too tall (my eyes are about 3/5 from the bottom. I would prefer more like 3/4). But its manageable.

I did not see any obvious mounting hardware/holes on the back of this monitor so it may not be possible to wall mount it or put it on a lower 3rd party stand (included stand is fairly low with monitor bottom at 2 inch above desk).

Overall I am pleased with the monitor (i purchased it primarily for gaming and watching movies/shows on my PC).

Also note that monitor comes with a mini connect box that already has ~2m cable. You do not need a very long HDMI cable usually. In fact the 3m HDMI 4k cable I purchased flat out refused to work with this monitor. I connected a shorter 2m cable and monitor started working properly.

The windows DPI at 2 feet viewing distance is perfect at 100% scaling.
 
So for now the JU7100 and JU7500 seemed to be confirmed for 4:4:4. Now if only someone can be a test subject for the JU6700 lol

Wow and my "simulated" 48 curved test seemed tough at four feet, can't imagine two feet...IMAX over at your place Ziran. :D

Thanks for the review, enjoyed it.

For others asking "why 48" over 40" for desktop??" it's for many good reasons. Mainly because it can be pressed into TV duty in another room at that size a whole hell of a lot better than a smaller 40", as well as being much easier to sell at that larger more consumer-friendly size down the road.

Countless other reasons also, but to each their own. 48" for me, thanks again to Ziran for the write up.
 
Now that Ziran posted helpful instructions to get the 4k 60Hz 444 chroma working on his JU750 I can confirm that the UN48JU6500 (flat version) is also 444 at 4k. I'm using GTX970 in SLI. I was just about to give up but once I renamed the HDMI 1 port to PC everything work just fine. Samsung should work on that...shouldn't need to rename the ports.
The flat monitor suites me fine and I bet will give better off axis viewing not to mention it is a good bit cheaper than the curved model. Having used a 40 inch seiki for a long time going to 48 inch is very nice and 60Hz rocks compared to the old seiki.

Awesome, if the 6500 has 4:4:4 then it's probably safe to say the 6700 also does. Any way you can try to do some input lag tests? :)
 
Anyone know if there's panel quality difference between JU6500 7100 7500 etc, or is it just fluff like 3d and smart features?

Awesome news! Do you have any other monitors with established input latency times?
Taking a picture of both at once with http://tft.vanity.dk/ running would give us a good general idea.
 
Now I'm tempted to pick up either the 40JU6700 or the 48JU6700 even though I currently only have the older Titans. The only thing holding me back is that we really have no idea when the 390s are coming out at this point.

I just noticed Samsung has a crappy return policy (15% restocking fee). Crutchfield will carry these TVs and has a 60 unconditional return policy, with only $10 return label. I'll probably wait for them to have it in stock before I decide to purchase.

Thanks for the quick and great review :):):). 40" curved Samsung is now definitely on top of my list before the Philips 40". Some questions:

Is shadowing resulting from the electronics or the panel type? If it is horizontal in Beng and vertical in Samsung it points to electronics for me?? I wonder what Samsung support would have to say about this, maybe firmware update could get rid of this??? How annoying is the shadowing? Is it very visible with bright windows on dark background?

I understand input lag is not an issue, but could any cursor trailing when mouse is moved quickly be visible? This is best seen on the black background. Overall, any
trailings with moving fast objects?

You mention issues not related to monitor as monitor per se (plumbing as TV, selling). Logically it follows that 40" (+ Ziran mentions 48" too high) is optimal as monitor from the exclusive monitor point of view.

What I mention, are the reasons why a 48" works for me. Doesn't work for you? Cool, no problem, they offer a 40".

Wonderful to have choice isn't it? That way we can all be happy. :cool:
