Connecting a Raspberry Pi to a display at home is easy – use a HDMI cable and connect it to a TV. However, one of the sticking points in school is finding a suitable display to connect a Raspberry Pi to, we don’t have any HDMI displays. Until now we have only been able to use 1 x Raspberry Pi because our only option was to connect it to a whiteboard using a composite video lead.
I recently purchased a HDMI Male to VGA Female output Video Converter Adapter Cable With Chipset from eBay with the hope to connect it to the many VGA monitors we have in school, this would then mean we can set up more Raspberry Pi’s in school.
When the adapter arrived I thought GREAT!…but I plugged it into the monitor and nothing happened. After a bit of research on the internet I found out that I needed to change some settings on the Raspberry Pi from within the config.txt file. Here are the instructions on how to do that:-
1. Open LX Terminal
2. Type sudo nano /boot/config.txt and press enter
3. Uncomment (which means remove the # symbol) hdmi_safe=1
4. Uncomment hdmi_force_hotplug=1
5. Select ‘Exit’ option
6. Select ‘Yes’ to confirm changes
7. Reboot the Raspberry Pi and once connected to a VGA monitor using the HDMI Male to VGA Female output Video Converter Adapter Cable With Chipset it will boot up on your VGA monitor.
SUCCESS!!! We can now use a Raspberry Pi anywhere in school with a VGA monitor.
