I have a thorn 55 inch Smart TV and can’t even watch Netflix Stan or Foxtel this TV is rubbish

Try a factory reset and see if that helps

look in the menu to see if the balance is adjusted correctly here on page 23 AWA thorn 55THLCHD3 User Manual Page 23

To play 1080p movie, just do it. No further move needed, cuz most smart TVs have no problem in playing back 1080p full hd videos. As for 4k Ultra hd video, you'd better downscale it to 1080p if you're not sure about your tv resolution.

Once you are connected to the wifi, go to settings and do a systems update. If there is an update, then it will update to the newer version.

Bill, The 50H7GB's smart features are based on the Opera OS. Hisense uses an Opera-based platform for its connected features the same system/browser you'll find on Nintendo's DS and Wii video game systems.Check the attached links,instruction and guides, Good luck.
