Ever notice a little red dot on your BenQ projector system settings?

You might have ignored it before, but this time, you’re ready to give your projector the system upgrade it needs.

Keeping the firmware of your projector updated helps its performance in many ways. 

It removes bugs present and resolves ongoing system issues, adds in new features, levels up settings, and adds support to existing software.

For BenQ projectors, you can update the firmware via a manual update or via a USB stick. 

And unlike other devices where system upgrades can take hours, projectors are relatively simple machines and these upgrades can be done in minutes. You can leave it updating while you’re finishing a chore or working out!

Before you get started, make sure you have a USB stick ready and you have found your projector model on BenQ’s website. Each projector has different firmware updates, so best to search it first.

We’ve summarized the steps below to update your BenQ projector firmware, so you don’t have to!

1. The Upgrade File Isn’t Visible On The Projector

For cases like these, it’s usually an issue with the format of the USB. Before you paste the files on your USB stick, go to “File System Option” and select “FAT32” in the options from the pop-up menu.

If the USB is fixed already, redownload the files and paste them again on your USB stick.

2. The Update Process Is Failed

Unfortunately, you will need to start the process again. If it still doesn’t work, contact BenQ online or go and visit your nearest BenQ servicing center.

3. Do I Need To Update My Firmware? My Projector Seems To Be Working Just Fine.

The answer is yes. And there are several reasons why this is important.

The most apparent reason is to update the current systems and to add on new features. By having the most updated features, you’d notice a change in the performance of your projector. These usually involve improvements in the color and lens movement settings.

Linked to this is the prevention of the device being obsolete. By having the latest features and commands, your projectors can handle any content, software, and even devices used with it.

And lastly is the removal of bugs, glitches, and other things that could slow down the processing of your projector. We hate it when some functions don’t work upon clicking or if it takes 3 seconds for your device to load a function. Get rid of all of these by doing the update!

4. How Often Do I Need To Update?

The answer is simple – every time there is an update available for your device! 

These firmware upgrades usually span a period of months, so you don’t have to worry about weekly or monthly checks with your projector.

Once you see the notification present in your settings menu, or when you receive an update from the manufacturer, then it’s a sign to start the process.

5. Any Precautions Before I Proceed With the Firmware Upgrade?

The main watch-out for projector upgrades is to make sure that the firmware file is the correct file for your device and model. 

If you apply an upgrade not intended for your model, the usual consequence is that some functions will no longer be operational. This is a bit technical, but in simpler terms, the old microchips and algorithms will be overridden with the new ones. Thus, leading to the inaccessibility of some programs and features.


One of the simplest ways to give your projectors, or any other device, proper care and maintenance are doing a firmware upgrade. With just a few clicks and in a short amount of time, you can see a drastic improvement in the overall performance of your projector, while keeping it up to date.

It’s not always that you get a prompt to update your projector, so don’t ignore it once you receive their signals!
