I saw about 4 blur lines moving across the screen w/ 1000px separation. (I make it full screen). Is that good?
I give up, you obviously can't or won't read.

Well looks like I cancelled too late with Amazon and the Samsung UD970 actually ended up shipping. Very bizarre. But one even weirder thing is 2560x1600 is the highest resolution I can select from the Nvidia control panel. I have to manually create a 3840x2160x60 resolution which works without a hitch.
However one very bizarre thing I've discovered--the framerate of games right now is about 10% lower consistently between running on a 4K TV with HDMI 2.0 versus running DP1.2 on the Sammy. I don't get it at all. BF4, Witcher 2, all the games I've got seem to run slower and I don't get it, I wonder if its the manual resolution causing this. Did you have to create a manual resolution or was 4K available on the Nvidia menu?
what is the software / hardware spec. of your PC?
The Samsung UD970 is louder than my LG 49UB8500 for sure, which is dead silent. Between 50-100% brightness it makes what sounds like either coil whine or capacitors resonating which I can hear from a sitting distance of 2-3 feet. But if I turn down the brightness to 40% or lower the sound loses about 90% of its intensity and you have to be basically within 2 inches of the screen to hear it.
I'm using Win8.1 with the cable that came with the box. I intend to use these mornitor at 100% scaling and the game that I tested with works perfectly (Tropico 5 & Civ V)
I just ordered this 10ft cable since the one that came in the box is a little too short for me. Should get here by sunday so I will let you know again if I have the blank screen problem.

Windows 7, Intel 4770K @4.2GHz 16GB DDR3 1600, GTX 980 @1466MHz core/7600MHz memory, Intel SLC SSDs.
I might try Windows 8.1 and see if it scales any better at 4K? Windows 7 text is pretty ugly at 4K @ 150% scaling with a lot of edges and borders near text cut off, and and setting resolution at 1440p @ 100% scaling seems to produce clearer text.
Maybe its because I'm running a 26awg 20 foot cable. I'm picking up a 24awg 16 foot cable soon.
The internal clock rate of my signal is clearly 2560x1440 because under custom resolutions I can choose the clock rate and its 2560x1440 @88.6KHz. If I Choose 3840x2160 @133KHz under the clock rate I get a blank screen. So I think 3840x2160x60 signal can fit under the clock rate of a 2560x1440 signal...or something like that. Too bad a 24awg passive DP cable costs like $125. If the connector end is HDMI its only $15. Maybe I should learn to solder my own cables lol.
Hey can anyone comment how responsive games are on this monitor @ 4K?
Is there noticeable input lagg? Is there much blurry movement etc? Thnx guys.
You can overclock the panel
I'm not seeing anything about this in the thread, is there a source?
I kind of doubt a multi-input monitor can overclock @ 4k without dropping frames.
Changing the overdrive preset is not overclocking the monitor.
Overclocking implies you've gotten the monitor to run at a higher refresh rate.
Just for future reference, remember that what you're referring to is the overdrive.
Apologies as I was a bit confused by your phrasing, but they're not one in the same.
Can anyone with the 49UB8500 post some benchmarks or gaming impressions? I've been using a 47" LG IPS as my main for years, next to a Sony 24" HVA.
4:4:4 chroma made a huge difference with a proper cable/card, but other than that I can't see where people are getting this blur/input lag stigma from. Inputs are instantaneous in gaming, nothing like my projector where there is a discernible lag.
Well there is input lag to any monitor, most of the time it is not noticeable because it is usually very small.

Also this guy did a short feedback on newgg.com
http://m.newegg.com/Product/index?itemnumber=9SIA4JH2113837
He claims it is too high MS (I am guessing he is referring to the input lag) for FPS.
I still have the S27B970D and according to TFTcentrals detailed review, that monitor has a 24ms input lagg, which is considered too high for competative gaming.
I found that monitor to be fairly good for gaming in my opinion, I played starcraft 2 on it and left 4 dead 2, but I did notice that when the Hunters move extremly fast in L4D2 it is a bit blurry and can be hard to aim and shoot th em down, other than that nothing else was blurry. If this 4K monitor is atleast as good as that then I would be happy.
Input lag and response time are two different things. The blur you're talking about would be due to the response time.
Here is my impression so far
Cons;
- The standis very shaky, I will replace them with ergotron arms.
- Cable that come with the LCD is very short, I think it is 6ft, considering if you need to pivot the lcd, I end up order new cables for the panel
- There is no customer service from Samsung, If you call them you will get to a call center where they just read the manual to you. Unlike my previous LCD (NEC/EIZO) when I called the representative they know what I'm talking about.
- No speaker built-in for those who cares.
- Natural Color Expert software only support single monitor if you are like me whom use multiple monitor, you have to use 3rd party calibration tools.
- Display control is not easy to navigate.
The BenQ BL3201PT has now been announced with very similar specifications. The only advantage I can see of the Samsung is that it is a wide gamut monitor (covers the Adobe RGB color space). Samsung is priced at $2000 while the BenQ is priced at the unbelievable $1000! So if wide gamut is not needed, the BenQ is a no brainer or, am I missing something here?
Benq seems to based on the 3200PT while the Samsung is based on the S32D850. The Benq thread is full of people complaining about a noisy power supply. Not saying the difference is worth $1000 necessarily but...in the late 2000s people were paying twice as much for Apple Cinema Displays compared to Dells for similar reasons (the old 30" Dells were noisy suckers and the 30" ACD had a external power brick). Not that I'm saying the Samsung touches the ACD for build quality or silence.

I said overclock the panel I never said increase the fresh rate of the monitor. If I wanted to refer to refresh rates I would say it. Also overdrive been referred to as "overclocking the panel" by review publications for years so there's nothing controversial of my use of the term.
Why is this monitor sold on ebay for an outrageously extra price of $2500-2900, when amazon or Samsung direct sell it for $1999.
Why do the ebay sellers charge an extra $500-900?
Those are direct from s korea.
So why are they more expensive, isnt samsung somewhere in Korea? They sell it for $1999.
So i have decided to buy the LG 31MU97 mainly because it is cheaper and has 5ms response:

What do you guys rekon?
