I plugged my Pi into a Samsung smart TV and got no signal. In the config.txt file I uncommented hdmi safe mode this gave me a picture but 640x480 and I want 1920x1080.

Could anyone give me any ideas how I can get this working.

It was the cable! Brand new out the pack but I switched it for a different one and it worked.
