New Samsung 4k for everyone.

How much bandwidth does 4:4:4 chroma use on the HDMI cable? My cables are 10.2GB max but I read that 2.0 is up to 18GB. Will I need new cables?

L * W * BITS * CHANNELS * hZ = Bitrate
3840 * 2160 * 10 * 3 * 60 = ~14.93 Gb/s

Yes, you'll definitely need new ones. Even at 8bit color it's 11.94, and this panel is 10bit with 12bit FRC.

Fuck, so the Titan X doesn't support 4:4:4 at 3840x2160 60Hz??

It does on Displayport, but since this TV only has HDMI 2.0 you're out of luck.
 
Depending on luck of the draw if your cables are short and quality enough they might just work. HDMI has no error correction so you'll know if it doesn't by "speckles" or similar signs of bit errors.
 
These Samsung monitors are the best 4K buy right now.
I'm glad I didn't give my money to Phillips, Seiki or Crossover. Looks like they are sourcing the same cheap panels.

Anyone looking for a large 4K monitor and have HDMI 2.0 cards should by Samsung for now.
 
I am a bit tempted to buy "UE40JU7005" cuved but there is a few things that makes me not wanting to do it.

1. I can not know for sure if it will work at 4:4:4. Seems that nobody in my country has bought it yet, or if someone has it he has no posted yet on the internet about it, heck there is no information about it on the Samsung page, no manual to be found either. Although I believe it is the same as the US curved but just different model number, I still can not be 100% sure if they use same chip etc so I would have to take a risk and ship back to the store if it does not work.

2. I'm not sure I would want to go back to a (low) PWM display after using flicker free monitor. I had the Philips monitor for a few weeks and then switched to Benq, I noticed that I can sit in front of the Benq monitor longer without the eyes getting so tired, so going back to PWM is not fun.

While I'm not going to get into your second concern, I can say with 100% certainty that this is a 4k60 4:4:4 capable display.
Just this thread alone has had at least three owners posting test images with full clarity. AVSForum has a few more examples. ;)
 
I don't know if this has been answered. Is there any height adjustment? When the display is set to the lowest point, how many inches above the desk would the top of the display be?

Edit: Sorry, should have mentioned it. Am looking at the UN40JU6500

No height adjustment, the 48" model is 27" tall, while the 40" model is just over 23". Using a VESA arm could lower this an additional 2" or so.
 
Is it preferable to game in PC mode @ 44ms or Game Mode and lose 4:4:4 support?

Yup, Chroma sub-sampling just affects high contrast color clarity, like colored text on a different colored background. It's effects are differing in intensity depending on what colors schemes you're viewing.

You won't notice in games since things move around so fast that fine detail is lost, and you won't notice in in movies because THEY ARE ALL ALREADY COMPRESSED. To save bandwidth, VCD, DVD, broadcast HD and BluRay use 4:2:0 chroma, because most people can't tell the difference in rich detailed movie scenes.

Not sure I agree with the 44/22ms measurement, as all our tests have indicated nearly half that. 44ms would definitely be noticeable, and I had no idea Game Mode turned it down to 4:2:2.
Could someone run the test images in Game Mode?

If another review confirms these 44/22 measurements, it'd be a deal-breaker for me.

Curved. I saw all of the new Samsung models on display side by side. The curved models stood out.

It being a TV with a ton of inputs makes 44ms believable.
Limiting bandwidth to 4:2:0 to lower imput lag sounds about right.

From what I see, using the adjustments recommended in the thread for Game Mode, I see minimal difference in picture. The gaming experience has been more responsive.

Makes sense to me, shame they don't use another method though. I'd still like to see some other measurement since ours have been so contradictory.

Sticky keys? :eek:
 
Now I'm sort of ambivalent that the 6700 can't support 4:4:4 in game mode. Well, I can always return it if I'm dissatisfied.

Lights Off. Ink Blacks. Looks like I have a Curved 40" 21:9 Monitor.

That 21:9 is exactly what I'm planning on doing! Any more insight on the setup? How's the current look? How do you switch between resolutions?
 
I just changed the resolution in the Nvidia Control Panel.
I had to start the game in 4K and then change the game resolution to the custom resolution.

Other games may need a different process to get it to work.

I'm interested in hearing your opinion on input lag when gaming in PC mode. I think you'll be pleasantly surprised at how quick it is...assuming you're not coming from one with g-sync.

I may be alone here, but I use GAME mode for FPS and PC mode for everything else. If you care enough about frames to run in GAME mode, and assuming you're actually playing the game, the scenery is likely changing so quickly that you won't even notice.

EDIT: Just found this table. Probably will look bad, formatted as best could.
EDIT2: Yeah it doesn't really format much. But 17.82GB was what I was looking for. Ordering new cables now.

How well does this display function as a display? I imagine its awesome in games but how good is it as a computer monitor for general tasks?

I bought the monitor for Productivity first.
4:4:4 support makes it the ideal 4K monitor. Text is sharp without artifacts.

I've been using Photoshop, Premier and Dreamweaver today.
The large amount of workspace is great.

Incidentally I have the 65" version, but I haven't connected a computer to it. I am not sure how it works as a display, but I would imagine the pixel pitch would be horrible for text at that size. I was concerned about the 40" version as a monitor but your experience with it is very encouraging.

Maybe we could all contact Samsung about lack of 4:4:4 support in Game Mode? Perhaps they can issue a firmware update to resolve it.

Oh I also assigned one of my 3 Titans as a dedicated PhysX card and it still output video (at least over the DP) so it's promising adding a GTX 960 to my config might work (if I don't blow my PSU. lol).

Oh geez, I just got a response from a CS support inquiry asking Nvidia if what I want to do is possible, and I got back a "Can you explain what 4:4:4 and 4:2:0 is?". lol

The 40" 4K is the same pixel pitch as the 27" 1440p. Text looks exactly alike.
I saw the 48" model, and it was a bit huge for desktop use, so I can't imagine 65".

I wasn't planning on using the 65" for that. I was wondering about the 40" specifically.

40"'s ppi is similar to 27" 1440p, which I feel is the sweet spot.

I'm eyeing the 40" version of this, I already cancelled my Phillips order and am waiting for a deal on these..
 
I have tried 3D on the 48JU7500 and its not really useable. First the built in Nvidia 3D support is unbelievably bad (its either 720p60 or 1080p24. that's it). I tried using TriDef ignition in the side by side mode (so 4kp60 / 2) and the monitor supports that but even then its 30Hz to each eye. The flickering and eye strain is immediately apparent so its not really useable.

So basically the don't buy this monitor because you want useable 3D. You will not get it (not today anyway).
 
Okay... I have the 48" 6700 up on my desk (replacing triple Dell u3011's). First thoughts:

1. Monitor height as it is now (top of monitor shelf is 4.7" off the desktop) needs some work. My level eye line is approx 16" above the base desktop. Minus the 4.7" monitor shelf and using the stock TV stand, my eye line is approx at 11.5", and the mid-point of the viewable screen is at 14". I can modify the monitor shelf to lower 1.5" and if I go with a VESA mount, it is possible to have my eye line be at the center of the display.

2. I still need to adjust display settings - I just got the system up with 4:4:4. Text is very sharp, and overall I'm extremely pleased with it! I am sitting approx 34" away from the display.

3. I played Diablo 3 at 4K resolution (single 980) and it will take some getting used to. I liked it but I need to try a lot of other games and see how I will adjust to it.

4. I played a few mkv files (Hobbit - Unexpected Journey, and Archer S05E01) via VLC. WOW!!! The video is beautiful. There is a depth to the movie/TV is makes it quite mesmerizing. I do have a Toshiba 65" 4K TV so I'm used to the upscaling. This "TV" does an amazing job.

5. Screen real estate is awesome and exactly what I was looking for. I will still setup 2 of my Dell u3011's in portrait as I am not used to only having 1 display. I will need to do some research on the best way to mount the TV and 2 u3011's.

6. HDMI cable length is going to be a challenge. I have 3 different 50' cables coming tomorrow that I will try. I'm not overly optimistic that I'll find one that works, but I have to try as my preference is to keep my computer in my office closet to help with noise and heat.

I'll post some pics tomorrow - pretty beat right now.

Edit: got a second wind and wanted to add a couple of pics: http://imgur.com/a/dQkrA?gallery
