Hey, a week ago i bought Samsung UE50NU7092 which i connect to my PC. First thing i did was calibration, i used and lagom site http://www.lagom.nl/lcd-test/ and https://www.eizo.be/monitor-test/ , everything was great and i was happy. A day ago i dont remember why but i wanted to see what gamma im on so i tested it on and on gamma page on https://www.eizo.be/monitor-test/ everything is now green/yellow which was grey few days ago. Most of gray moire patterns appears green/yellow and i dont know what the cause is. I factory reseted TV, checked every setting, my PC isnt issue because imgae on pendrive is the same. Is this normal or my TV is broke after few days of use, or i shouldnt worry too much about it ? Any help ? On this pic, it should be gray but its yellow/green. When i zoom 1,5 this issue is gone, is this normal ?
