gem of a (cheap) 4k panel

This is probably the cheapest 4K television being sold in India at present along with Samsung's 40hu7000. I bought this a month back and I am surprised how the internet is lacking a good review of this splendid panel. My previous HD ready TV (Samsung LA32R81B) was 8 years old and simply refusing to die. I tried everything short of taking a hammer to it but it simply wouldn't. i added a chromecast to make it smart and it satisfied me for a few months but the urge to upgrade was high although t...

cheapest 4k tv

i will mention the difference between 4k and ultra HD you need to know so here is the differences
Difference between Ultra HD and 4K

Technically, "Ultra High Definition" is actually a derivation of the 4K digital cinema standard. However while your local multiplex shows images in native 4096 x 2160 4K resolution, the new Ultra HD consumer format has a slightly lower resolution of 3840 X 2160.

NetCast 4.5

LG had moved to new platform WebOS for their smart televisions, however this model uses NetCast 4.5 platform. There is no way to upgrade NetCast 4.5 platform to WebOS platform. Some application like twitter, facebook had already withdrawn support and LG will soon withdraw it's support for NetCast 4.5. So if you'r looking for good Smart TV wait for WebOS or go for other manufacturers.
