I bought this unit today but don't have a 4kTV, didn't think that was an issue though. However when I connect it via HDMI to my Samsung TV, the initial Blu-Ray logo comes up but then tv says "Resolution not supported. Change resolution of external device" I cant do that as cannot see anything to go into menus. My TV recognises that its also an Anynet+ device as can pull up a menu on tools from tv remote to search Menu, Tools. Title menu but none of this seems to work. Do I need to take this back as not a 4K tv? Cant check firmware either for the above reasons.
