I haven't used my RaspberryPi in month and today I wanted to start it, but my HDMI monitor doesn't get a signal. The LED 'OK' is shortly blinking at the beginning but then turns of. All the other LED's are on continously.
I've tried several settings of config.txt and two differnt OS. I have no problems using my SD-Card on my Laptop.
The last thing I did with my Raspberrypi is working with the GPIO, but everything worked just fine.
How do I boot my RaspberryPi and get a signal to my monitor
