hello,
When I turn on my tv and start the raspi, everything is fine. I enjoy and then I turn off the tv (the screen). The raspi continues to work. If I turn the screen back on 1 minute later, the page I was on is displayed. If I turn the screen back on 30 minutes later I have a black screen with ‘no signal’. So I uncommented the ‘hdmi_force_hotplug=1’ line. The problem seems solved. Except that, if now I turn on the raspi before the tv, the resolution is 600 x 480 instead of the default 1360x768!

Can a moderator delete the duplicate ‘no signal screen’ post please ?
