thank you Arseen for your feedback. i'm waiting again a long time 
Hopefully not too long.

with TV mean your PC monitor?
Both.
I used 47" Full HD TV as monitor until it broke
The one I use now is 42" Full HD, but the colors are somewhat off and flux.
I'm currently torn between fixing the one I had if it's not too exzpensive, or buying 55" or 65" Ultra HD (= 4K) telecision as a replacement.
If latter I'll also have to upgrade my computer to take advance of the added resolution.
