I have been tasked with the job of replacing a Sony 40 inch flat screen in a local ELKS club bar. Canned CFL lighting in the room that is bright enough to read a book by. SPORTS are on the whole time the bar is open, with every thing from baseball, to football, to NASCAR, to ESPN. Sound quality is not too important as it is usually muted. Perfect picture for movie viewing is not important. What is import is a lag free, bright picture. We have room for a 55 inch so that is already decided. Out price range is $500-650. We have charter cable (digital). I have been thinking of 4K UHD HDR10 not that we have any of that available now, but might in the future. A BRIGHT picture with NO LAG is the most important thing. That and the ability for it to hang on the wall and deliver a good picture for 5 years without needed any service. Smart TV is not needed but I am sure it will come with it. Any ideas would be appreciated.
