Hi there and welcome
Are you using a RGB to HDMI cable adapter?
So just a cable with RGB at one end and HDMI at the other?
Tell me the make and model of it please
of the cable or converter your using, the rgb to hdmi converter
ok, but that wont work for you, as its in reverse.
This device converts HDMI to RGB, you need to convert RGB to HDMI, this is why it is failing.
