After fiddeling two hours to connect my just 11 years old DVD player with a cheap Full HD monitor I decided to buy the mentioned Samung 40 inch UltraHD monitor and ...
Viewing of high res images is done by the on board OS/Software of the TV, reading files from USB:
+ Viewing EOS 40D images at 7 MPix (3240 x 2160 screen pixels at 3:2 aspect ratio of the images) is ... BREATHTAKING!!! (Distance to the screen roughly 50 cm, pixels not visible to me)
It is like looking at a very good and well lit print in 50 x 75 cm with great color reproduction and high contrast. From reviews I remember contrast values between 1000 and 3000 meaning 10 - 11,5 EV.
It is more "beeing there" than "looking at a photo of" ...
Usage as Desktop:
Cannot report about it because the graphics card of my PC is to primitive for that display. I like fanless graphics cards so I have to find a fanless card for 3840x210 resolution @ 60Hz.UPDATE 2015-01-16:
After several hours of image watching I am not shure if that TV/display is a PC monitor replacement: At 50cm distance you are off axis by 45-60 degree. In that case a curved display might be more efficient - and some improved panel technology like OLED. But I will do the relevant "tests" soon.
Mirroring a tablets screen:
Works after easy setting up the connection. Resolution is only 1280x720 (800) what the mini tablet can do but it is absolutely sufficient to bring readable content to the screen or to view a you tube video via the tablet on the screen.
There is a lag between user input and response of the TV screen but for the use from time to time it is no problem.
Just thinking of camera with life view engaged + tablet with EOS Utility to mirror the camera view to a larger screen ...
Common remarks about the display:
+ Viewing angle isn't the problem. @60 degree off center axis colors & contrast are flat, but at normal wide viewing angles colors are at least good.
+ Very good color reproduction out of the box but I read some reviews that showed very high color precision after calibration (cannot do that at the moment)
+ Good brightness - reviews report up to 450 cd/m² are possible
+ good black levels - good for me as SF fan. Space has to be deep black ....
o Motion reproduction is IN MY OPINION absolutely o.k. The simple upscaling of the TV set is mentioned in some reviews resulting in harsh detail loss for fast moving objects. I haven't observed these effects but I only used FullHD content via USB and DVD via SCART (1k resolution or less).
- A little bit cloudy but visible only in special situations e.g. the blue background screen of the satellite receiver I will use furthermore.
The panel technology is PVA which I have used with a very good EIZO S2100 computer monitor in the last 5 or years.
Usually I am NO early adopter but in this case I hurried because
(1) I want resolution - a dream of mine came true: looking images near the resolution they have in a singel view.
(2) some sharpness loss in TV/video mode is acceptable for me
(3) I see no longer too many problems in high resolution displays: proven technology
(4) There is some risk that 40 inch Ultra HD displays will vanish from the market soon because "it is to small for the resolution" and
(5) 40 inch for Ultra HD seems to me ideal as computer screen used for image editing but also for text writing, drawing, programming, etc.
(6) 4 x HDMI 2.0 and 3 x USB (1x USB3.0) gives some options for future extensions - future entry models might be less well euipped after Ultra HD is adopted by the masses.
The Samsung UE40HU6900 has visible brightness variation with the viewing angle but colors seem stable. Reviews show that this display gives good color reproduction, contrast and brightness. The week point seems to be motion reproduction for movies, but this might be solved by using a high quality external tuner.
My usage scenario is at the moment
* replace the defect DLP beamer (50 white pixels within 2 weeks after just 1750 hrs of operation)
* have a device to display photos near their native resolution
* plan to use it as computer screen in my living room with a PC in the room above (need a new graphics card for that purpose)
* view contents of my tablet via Miracast wirelessly.
At 500 Euro it seems a bargain ....
If I buy that display/TV I will give feedback!
