Hisense 50H7GB1 owner here. Looking for some answers to update my TV so I can enable HDR. I also want to know the best gaming settings for my Xbox One S on this TV. Trying to make the best of what I have at the moment. I'm a online competitive gamer and any help is appreciated. I've contacted Hisense last night and have yet to get a reply so I'm asking on here. I don't have a PC so if I need to download a firmware would Dropbox work? It's enabled on my TV so I'm thinking I could use my iPhone to do this.
