I am running a hdmi 2.0 certified cable with a UGREEN hdmi female to micro hdmi adapter and even after using the
tag in the /DietPi/config.txt file I am still only able to select the 30hz option. If I can get the 60hz option I’d be happy to stay on DietPi for the time being. FYI the television is a Samsung RU7100 and all ports are HDMI 2.0 certified and can run at 60hz. However, if I cannot get anywhere I will also try burning raspbian on an alternative micro sd card and perform testing just wanted to check if there was a limitation with the software or have other people reported success with this? Apologies if this has been posted before, I searched on the forum and could not find a thread related to this. Thanks in advance for any help you can provide. Cheers.
