Help needed.
Hi all. On my Hisense u9a I have a gamma calibration setting that I can adjust, however I'm not sure how to. When I go into the setting it has 2 titles. Input level and gain. Input level is default at 5% and only goes up in 5% levels until 100%.The Gain setting goes to plus 12 or down to minus 12,the default is zero. Now I know by using these I can get the greyscale bang on as well as colour but I don't know what these settings actually do. Can anyone help me please.Thanks all.
