The Red led of the PI is alway On and the red one is blinking and later(around 3-4minutes) turn Off. I tried to install Raspbian in other SD, and modify the "config.txt" In the config I tried to uncommment:

hdmi_safe=1

hdmi_group=1
hdmi_mode=16
hdmi_drive=2
config_hdmi_boost=4

The Pi should automatically connect to the monitor without having to change anything.

Are you connecting to the correct HDMI port on the Pi? It's the one closest to the power jack.

Do you know that the connecting cable is good? Can you connect to the Pi using SSH?
