I have posted this concern in other similar topics and every time i pointed out that there are two types of similar samsung leds .. where one has superior color quality and other has a pathetic one ... i don't know which one u got .... i got a lcd (40") at home and i'm in islamabad u are welcome to visit and i'll explain practically OR i can post pics of same setting same channel or movie on both LEDs (both tvs in the family and i generally visit on weekend ) here but i'm not sure if pics will give the details i require to explain my point ... i can also tell u a long story when a friend and i visited imperial mkt to buy a led smart tv and ended up buying it from metro ... 1080p is not a bench mark nor is getting updates ....
just these checks u can do on your own .... your tv has complete model number like ua40f6600xxxxx write down the complete number and google sites outside pakistan may it be samsung site now see what inputs and output connectors it has then check ur tv if its the same its likely to be "eik number" .... secongd check is the service menu and its settings find the code from google (just posted a link in the end) see what all is there and compare it to specs of tv the samsung site has ... lastly u can run your serial number on samsung site
i'm still 100% certain there are lot of do number tv in imperial mkt ... just remember the code of opening factory software go to the mkt and try it will not work. i did it practically
