Here’s the good thing: you can fix these bugs with a simple firmware upgrade. 

Is your JVC projector lagging? What exactly can you do about it?

This article includes all you need to know about updating a JVC projector’s firmware. Keep reading to find out how to check for available firmware updates. 

What is Firmware?


Before we delve into the process and requirements of firmware upgrades, we’ll explain firmware.

Firmware is written codes and instructions responsible for making a device come alive and perform efficiently. 

Unlike regular software written for specific tasks, firmware is written right onto hardware to guide a device towards its fundamental tasks.

Firmware is present in most digital devices like traffic lights, digital wristwatches, mobile phones, projectors, and others.

Wherever firmware is present, you can upgrade it once a manufacturer releases a new firmware version.

Firmware updates are essential for every digital device to operate efficiently, and your projector is not left out.   

Do you notice faults or signs of underperformance in your projector? If these faults are not hardware-related, it is most likely the firmware that needs upgrading.

During a projector’s firmware upgrade, functionality codes are rewritten and improved. Also, additional functionality is included. 

We advise that you find out if a firmware upgrade is available. You’ll often notice improvements and new features after every upgrade.

Pro tip: Don’t wait for your projector to malfunction or develop lags and delays. Check for updates occasionally to stay on top of things.
