Mini-Review: Samsung 40KU6400 as a monitor

I bet that looks sweet.

Oh it really was - any time I've tried to use TV screens in the past, it's looked washed out, dull and of course had lag issues (at 4k). The colour reproduction wasn't as good as an IPS screen but it was pretty damn close. I took a screenie, which I'll upload later.

Decision made for me - I'll be getting the 40" samsung to replace my 28" 1440p screen.
 
Can anyone post a video of ultra wide on this thing?

I'm really contemplating buying one of these. Just a bit sad than 1440p won't be a possibility.
 
OP I decided to go for one of these on Friday, the only thing im struggling with is i'm finding blacks are getting crushed a little, and in order to see them correctly I'm having to up the brightness quite heavily, which then ends up with a washed out image. I only have a Spyder2 atm, so just in the process of calibrating colour now as good as I can with that aging device, any advice from other owners appreciated.

fyi i have aligned to the settings you suggested
 
Scrap that, looks much better now I've re-calibrated. Loving it so far, however it's taking a little adjusting to over my 27" 1440p monitor, however photo editing is an absolute joy now with such a large amount of real estate.
 
That's he major thing im umming about. With HDR set to become mainstream, will I be missing out if I pull the trigger on a 4k tv now? Im reading that HDR actually not so fantasic for monitor due high brightness but 1000 nits?!, that sounds like it would blind me? I get uncomfortable using my current 1440p monitor so I need to turn it down from 320 nits for long term comfort.

Created a custom res of 3780x1620 and disabled gpu scaling, looked really good and still native (1:1 pixel), tried Project Cars and it's a solid ultrawide experience.

Yes, its the best of both worlds. I have a custom resolution of 3780x162 no scaling, for some gaming. Its great to have 21:9 and 4k 16:9 for productivity.

I do admit that WoW on 4k ultra settings still gives me 60fps on my 980ti (inno3D x3 Ultra. stock/boost: 1152/1241 // GDDR: 7.2Gbps)

Its also great that I can increase the web page zoom so I can increase the font size, whilst still seeing the same screen real estate as my previous 27" 1440p (non zooom). I have poor vision. Main reason for a 40" 4k TV/Monitor.

I get almost no black crush even uncalibrated it might be worth checking your settings:

On the PC, Nvidia Control Panel I have
Desktop Colour Depth: 32 Bit
Output Colour Format: RGB
Output Colour Depth: 8 bit
Output Dynamic Range: Full (This is important)

And on the TV, ensure "HDMI Black Level" is normal and you have set HDMI 1 to UHD Colour 'On'..

I found the HDMI Black Level set to auto is actually defaulting to 'low' which is limited 16-235, so this needs to be 'normal' to match the full dynamic range setting in the Nvidia control panel.#

You should be able to get very close to seeing all black/white blocks even without calibration on http://www.imaging-resource.com/ARTS/MONCAL/CALIBRATE.HTM

But calibrated, it's great, I can see all black/white levels

I think you could be on to something, however I'm using a 7950 with the crappy new Radeon Settings application which seems to have very little control compared the the oldder catalyst control panel. Has anyone on here teamed this monitor up with an AMD card?
 
There is a great deal of similarity in terms of features.

The main difference is in the Crystal Colour (I think this is part processing, part pixel drive circuitry), this gives it a slightly wider colour gamut (86% vs 83% DCI-P3) and as stated above, slightly increase PQI (1500 vs 1300)..

It also has slimmer bezels if that counts for anything.
