1/ I successfully pasted the zipped file on the USB stick but it doesn’t seem to work, nor appears on the firmware selection. What should I do?

an issue with the format of the USB

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/ Oh no! It says “Upgrade Failed.” Do I need to restart the process?

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.

reasons update BenQ projector firmware

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?

time to update projector firmware

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?

firmware upgrade

The main watch-out for projector upgrade 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 one. 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!
