I have recently purchased this Samsung tv and am extremely underwhelmed with it. No matter what I do the picture is just not height or vibrant enough. I use the standard picture mode, with the brightness on 50 which is max, I have turned all eco solution settings off which helped but anything is Amazon prime is too dim and just not very vibrant. I’ve contacted Samsung support and they just tell me to turn up the gamma and shadow detail which just makes the picture look worse. I’ve updated the tv to 1410 which is the latest software and have reset multiple times. This set has great reviews and won an award, why is my one so bad. I’ve done device care which says all is good and the picture test, just don’t know what’s gone wrong or what I can do, any help would be great. Amazon prime is pretty bad but all sources are pretty dim, surely the backlight can’t be faulty already, happened when I first got it, can’t return it now :(.
