I have RPi4 and RPi5. Everything is OK, but I can't set neither one to 2160p/60Hz.
My TV accepts 4k @ 60Hz @ 4:4:4. I have no problem to sent 2160p/60Hz videos from my computer, but not from RPi because I can't set it to 60Hz.
I found information in this forum that I should go to config.txt and add "hdmi_enable_4kp60=1", but I have no idea where to find config.txt I went to folder Configfiles, but can't find config.txt
Can anyone help me? Thanks upfront.
