Does your monitor's HDMI port works ? Can you connect it to another device to see if it receives and displays HDMI video ?
Try playing with theconfig_hdmi_boostconfiguration parameter in theconfig.txtfile. From Video options in config.txt:config_hdmi_boost
Configures the signal strength of the HDMI interface. The default value is 0 and the maximum is 11.The default value for the original Model B and A is 2. The default value for the Model B+ and all later models is 5.
If you are seeing HDMI issues (speckling, interference) then try 7. Very long HDMI cables may need up to 11, but values this high should not be used unless absolutely necessary.
