Follow this tutorial to correctly configure HDMI on Raspberry Pi.
Configure HDMI on Raspberry Pi
Before I start configuring HDMI let me show you that my HDMI looks something as shown below, you can see that the display is so large that it does not fit on my laptop screen and I have to keep scrolling up and down to get a full view of the screen. So, let’s solve this kind of issue by configuring HDMI.
To correctly configure HDMI, follow the below-mentioned steps:
Step 1: For configuring HDMI for Raspberry Pi, the boot/config file is used. Just use the below-written command to open the required boot/config file using the nano editor:
Step 2: Now into the boot/config file try to find #hdmi_safe=1 argument by scrolling up through the file:
Step 3: Once you have found the hdmi_safe=1 argument, just remove the “#” symbol from the left of it to uncomment the argument and as soon as # is removed the color of the argument will change to white:
Note: Ensure that hdmi_safe is equal to 1 if there is any other number just change it to 1.
Step 4: Now scroll up little bit more in the boot/config file and search for the #config_hdmi_boost=4 argument in the file:
Step 5: After finding #config_hdmi_boost=4, uncomment this line too by removing “#” from the left:
Once you are done, save the file by pressing Ctrl+X and Y keys.
Step 6: The final step is to reboot the system so that it can restart with the new HDMI configuration.
After rebooting you can see in the image below that now my screen is well-fitted and I can see full screen view:
Conclusion
To configure HDMI on Raspberry Pi, just open the /boot/config file by using the nano editor then uncomment #hdmi_safe=1 and #config_hdmi_boost=4 by removing “#” from both arguments and save the file. Finally, reboot the system so that it can restart with the new HDMI configuration.
