When Raspberry Pi is using a HDMI-VGA adapter is necessary to add an extra configuration in config.txt file (It must be located in root directory but If it does not exist you need to create it). Add next lines at the begining of the file.

#HDMI-VGA Configuration
+
hdmi_force_hotplug=1
+
hdmi_group=2
+
hdmi_mode=16
+
hdmi_drive=2
+
+
This setting will force a screen size of '''1024x768 60 Hz'''. Although the screen does not support the new setting will work.
