What cons are there to 4K TVs used as PC monitors?

Hi all,
first of all- I am not interested of buying a 4K TV to watch 4K content on it or to play games on it. I need a 4K TV for productivity- 3D modelling/rendering and some Photoshop work.
What possible disadvantages are there to using say the cheap Seiki 39-inch LED 4K Ultra HDTV as a main PC monitor (aside of the cheap quality with the iffy bezel, or the weird line pattern problem, or warranty related issues).

1. Color- Is it possible to calibrate the colors using a hardware color calibrator like Spider 4 Elite? Does it work in the same way as calibrating a PC monitor? Could colors come close/match PC colors that way?

2. Does being an LCD monitor pose any problems when used as a PC monitor in terms of Hz? Would that lead to any flickering?

3. Assuming I bought one- how do I change the resolution to the native 3840 x 2160? Would it be just an option in the Windows/ Screen Resolution menu? Does it mean I need a special GPU which supports the 3840 x 2160 resolution?
if so- which series NVidia cards support 4K (I can't use ATI since I also render on NVidia cards exclusively).

Thanks for all the help.
 
Mostly down to panel type, quality, and refresh rate. Most TV's top out at 30Hz at UHD since HDMI can't do more than that.

In regards to your GPU most new ones can handle UHD for work easily, gaming is a different story depending on the graphical settings you use.
 
I'm not really up on the TV tech so how cheap are current 4k TVs exactly? There's some cheap 4k monitors due out soon for around £500 which will do 60hz over displayport. Might be worth looking into them instead of a TV.

Being a regular monitor you can calibrate it and all that. I'm not sure how good the colours will be as its still a TN display aimed at gamers though.
 
I think tv's will be restricted in as much as they will only support hdmi. Which I am pretty certain will limit the refresh to 30hz at that resolution due to bandwith limitations, going by the stuff I have read - which is pretty limited admittedly lol.
 
Grey level is different on pc and tv as well. Black starts at 0 and ends at 255 on a pc (RGB full) where as TV starts at 16 and ends at umm i cannot remember but it is different so all shades of black below 16 will be classed as 0 black meaning complete crush and detail loss.


That is how it used to be so samsungs setting of rbg level high and normal used to be a blessing. Just set it to high or normal which was full and limited and calibrate then. I would do my research if i was you.
