** OFFICIAL ** 2014 Samsung 4K UN55HU6840 Ultra HD Smart TV Thread

This appears to be a one of a kind model number that was released pre Black Friday.

I got mine yesterday from hhgregg for $899 + tax.

This is the official thread to discuss this set.

Based on a 1-day ownership ... here is my initial take (will update as I get more familiar with it).

Details -
- 60 Hz set with a Quad-Core processor (very fast)
- Not a 3D set.
- Smart TV / Smart Hub has Netflix, Hulu, Vudu, Amazon, HBO. M-GO etc etc. Bunch of Apps
- Has Netflix 4K and M-GO 4K apps
- Connects to 5GHz wireless without issues
- Black levels are weak out of the box
- Can configure Picture settings for individual HDMI ports
- Has 1 USB3.0 and 2 USB 2.0
- Plays 4K videos I downloaded from utube fine
- Very sharp looking pictures when calibrated (I did a quick one last night)

Calibration Settings (for now)
Picture Mode - Standard (I know movie is recommended - will play with it later)
Backlight - 4 (anything above this and the blacks start looking gray ... also there is light bleed)
Contrast - 95
Brightness - 48
All other noise and motion stuff has been turned off.

So I was awake till 3:30AM last night playing with the set.

The upscaling is absolutely spectacular. My 1080i over-the-air NBS / CBS etc. channels are breathtaking. I also watched regular Netflix 1080p shows and they look AMAZING.

A 55-inch 4K for $898 that has HDMI 2.0 and plays all 4K content ... and looks stunning. Thanks Samsung.

wow I was literally just about to ask you how the upscaling was, logged in before writing the reply and you already answered!

So the only unknown for me is how the 60hz refresh rate effects motion.

Did you happen to notice any motion blur?

I have all the Motion stuff turned off. I watched some football yesterday and it looked breathtaking ... but I am not an expert on detecting motion blur.

So I just played this file from within the Youtube App on the TV

With Motion settings OFF ... there were multiple traces left behind (blur? ... not an expert on this subject).
With Motion settings on SMOOTH ... it was incredible smoother ... but not 100% absent .. just one trace left behind.

Very happy with the upscaling ... but I said that already - 95% of the content I watch is 1080p ... so I am very happy. Having said that some of the youtube 4K videos I downloaded are .. insanely clear.

I could have saved on taxes by having it shipped from Tigerdirect ... but I did not want to risk shipping damage. hhgregg did not have a store display and had no intention of having one on display since its a blackfriday item only. I asked if it was ok if I paid for the set and had them open and hook it up at the store for me to confirm ... they agreed ... and that is how I was able to walk out of their store with the confidence that I was taking home something that looked pretty good.

Very happy. I am not sure what 120Hz or active 3D would have given me for the extra dollars. I watched football without the motion setting enabled and it looked darn good ... and as I indicated above I also watched it with Smoothing turned on and it was really subtle.

I just bought it. Picking it up tonight. Salesman tried to talk me into the 1200 dollar model because of local dimming. He called it a drop in model, meaning samsung makes these only for black Friday. Seems odd, but whatever. I just hope to see some sharpness upscaling on 1080 Cable content. Hopefully it will look better to me than the vizio m series I was about to buy, but we will see tonight. Also, it explains why they don't have a display because they won't be stocking them regularly after BF.

guys i think this thing is 120hz.

per tiger direct black friday ad. this model 120hz. it also says that on hhgregg website where its being sold. i actually own the tv and can say. i have a un60es8000 (which is 240hz native) and its only slightly different. so i would say its probably 120hz. i think that review website is wrong product-reviews.net). samsung is not being specific here though & thats the problem. if anyone can come up with some hard evidence its 60hz please come forward though. from all specs it seems to be 120hz refresh rate with clear motion rate 240 that was made for BF. i also have connected a 4k 60p source directly to more than one HDMI on back and got 3840x2160 60p every time. I'm not sure about pc though. from my mac i only get 3840x2160 30p. but thats cause mac does not have 4k 60p HDMI port on my macbook pro retina(confirmed by apple specs).

this would explain why this tv plays so well guys. the 6950 also has this same conflict of some websites saying its 60hz but its actually 120hz per several reviews on here (AVSFORUM)..

if we can get some clarification that would be great guys. here is a pic of 4k 60p plugged into the HDMI 2 (DVI) port. notice I'm getting 4k @ 60p. i can also get 1080p @ 60p or 30p.

I also get this rather i turn on the option for HDMI UHD color option or not!


one suggestion i would say is to tweak your modes to your viewing. i notice a coated film like picture out the box. but after tweaking my modes (dynamic, natural, movie etc). its gone. you just have to set it to what works for you i think

Can you share your settings?

Mine is listed in the Original post. What source are you using? I had to drop backlight to 4 (I have a dark room). the black level is inky black when content is playing (e.g. footbal helmets are jet black). But when the video is black ... I can see the backlight giving off a gray aura.

Just unboxed it about an hour ago. So far I'm impressed! I turned down motion settings and I'm watching Netflix via the app. Picture is super crisp. I watched a little basketball since football games are over for the night, and didn't notice blurring. I will try the blue test after my daughter goes to bed.

Is the backlight excessive? Mine is too hot and I have had to turn it down to 4 to keep the blacks from turning grey.

im noticing the mode your in sometimes has to do with that. also the content thats being played. 1080i has a grayish feel to it. but I'm assuming its because the tv is 4k and its trying to upscale 1080i. therefore i would suggest tweaking your mode settings and saving it that way for that HDMI input. if you check you won't really see this with 1080p blu-ray or 4k content its more with cable broadcast etc

Ok ... One way to test is this ... In a dark room enter these settings and tell me if the blacks are grey in dark scenes.

Mode: Standard
Backlight: 14
Contrast: 95
Brightness:45

The rest in default settings.

The above will not give you a calibrated picture but is intended to test if backlight bleed is causing blacks to look washed out.

Thank you for providing some info on this model as there is almost nothing online.I am really considering it. Are all of the HDMI's 2.0? Do we know the version of HDCP on this model? Did anyone try playing Netflix 4K content on it yet?

netflix 4k content works so does m-go.
per crutch field supposedly one of the ports have 2.2 codec. i haven't tested that yet myself. if someone can give me a way to test it real quick i can. and all ports seem to be HDMI 2.0.. i tried all except HDMI 4 and got 4k 60p

contrast and sharpness seem to play a major part in that grayish tone. turn does down for help removing that grayish feel

Thank you. Seems like a good TV & option given the price. Very tempting.

Yes, I am seeing the poor blacks as well, not a big deal for me: I don't watch movies in the dark because my wife gets motion sickness easily. I did tweak it down but I could see enthusiasts having a problem with it. One thing that is bugging me is that I have a few light spots around the edges, where it seems the bezel may be interfering with the backlight. Only noticeable with bordered movies. I'm not sure if you have that issue. I will say even with that: I'm blown away by the picture clarity with Hd content. It's also a bonus that this remote can control my STB and DVD.

I had the same problem when I first got the set. Based on advice I found on AVS ... I used a soft cloth and gently massaged that area. Now the problem is non-existent.

6840 vs 8550 vs 7150

Ok so my dilemma just got even worse. I am looking to get a 55in and trying to choose between the 8550, 7150 and the 6840. The 8550 and 6840 are both under $1000 right now and the 8550 just went down to $1499 at BB. I dont have to have 4K so the 7150 would do but if it makes more sense then I will go with it. Also dont watch any 3D movies so that is not a deal. What do you guys think....

I bought the 55-inch Samsung 4K for $898.00 and absolutely thrilled at the clarity and quality of upscaling. Anyone who says that 4K is not of much value for 1080p sources is absolutely wrong. I watched Jimmy Fallon last week and let me tell you ... it was like being there. Remember that blue curtain behind which he walks out from? ... that curtain looked silky smooth. Science and Nature shows look spectacular. Animated shows are out of this world - all sources were 1080p.

Also, anyone who says that a 4K set is only useful if you are sitting very close ... thats wrong too ... my wife commented that everything look very smooth ... and she was standing near the kitchen ... about 14 feet from where the 55-inch set was sitting. Its true .. Football never looked better ... the jerseys and helmets had a smooth sheen to them. Overall I am Very happy.

The screen ... with a soft cloth ... and gently. Try a small area first and do it when the room is dark.

This appears to be the same basic television as the xxHU6950 series, but with a simpler remote.

The 6950 series remote has the touchpad and voice control, and the TV appears to add 1 additional composite input.

Anyone got a photo of the back panel?

Back panel is identical to the 6950 ... the salesman at the store compared. It also has the joystick in the back.

Also meant to add that the Panel Version is KS02

The TV is made in Mexico.

This website does not have specifics for this panel ... so I think its a new version / manufacturer.
