 have a TCL Roku TV Roku being the operating system yeah and it's really nice but I was having an issue with certain shows being too dark now how'd you fix it I went to the Roku secret menu but there's some menus that you don't get on normally get on the TV but there's a whole bunch of ones that are buried in there so here are the menus that they give you there's a wireless menu because it has Wi-Fi images and ads menu that sounds interesting HDMI secret menu I think that's where I found the setting that fixed my problem okay wow
