HDMI to VGA converter is a low cost solution to connect VGA monitor with PI.This needs no external power supply & no settings to do.It supports VGA output upto 1080I (60Hz).As VGA doesn’t support audio,this converter has no audio output.


Remove the SD card loaded with Raspbian Operating System & plug it into your Laptop.For Desktop you need to use a Card Reader.Open the folder to locate CONFIG.TXT file.

If you open this text file with conventional Notepad , you can see that the display is not arranged & difficult to understand.

Download NOTEPAD++ here  & install it.

Open the Config.txt file with Notepad++ to see the contents arranged neatly.

Scroll down to locate following entries.You’ve to uncomment these entries by removing the #  mark

in front of the command.






The first one to uncomment is hdmi_force_hotplug=1  which forces Raspberry PI to use the HDMI port.If it’s set to 0 then your PI will attempt to detect the type of Display.

The second one to uncomment is hdmi_group=1 & then change this value to 2.

There are two Groups for HDMI.

Group 1 is defined by CEA – Consumer Electronics Association of America.When PI is connected to High Definition Television over HDMI this Group is used.

Group 2 is DMT (Display Monitor Timing) defined by Video Electronics Students Association (VESA) & is used when PI is connected to computer monitors.

As we’re connecting PI to a monitor , set this Group to 2.

Next one to uncomment  is the hdmi_mode=2  & change this value to 16.

Each Group (CEA & DMT) defines its own modes.As we’ve set the Group to 2 this value of 16 represents a resolution of 1024 x 768 at 60Hz.

A value of 28  represents 1280 x 800 at 60Hz

& a value of 35 represents 1280 x 1024 at 60Hz.

This value has to be set according to your monitor size & type.Refer here for values of different modes.

Finally uncomment the entry hdmi_drive=2 and leave the value to 2.This is to alter voltage output by HDMI port.For DVI output voltages set this to 1.

Save the changes & remove the SD card from the Laptop.Plug it to PI & power it to see PI boot window on the VGA monitor.

Following settings may also be of interest :


This setting can be varied from 1 to 7 according to the length of HDMI cable you’re using.For long cables set this value to 7.


This setting  forces PI to use a preset collection of HDMI setting which equals to (hdmi_force_hotplug=1 , config_hdmi_boost=4 , hdmi_group=1 , hdmi_mode=1 , disable_overscan=0)
