BenQ Projector Not Focusing (9 Ways to Fix)

If your BenQ projector is not focusing properly, it can be a source of frustration. Fortunately, this issue can typically be resolved with some basic troubleshooting steps.

In this article, we will discuss the possible causes and provide simple solutions to help you get your projector back in focus.

Let’s get started!

How to Fix BenQ Projector Not Focusing 

1. Malfunctioning Lens

When a BenQ projector is having trouble focusing, it is usually due to a problem with its lens. The projector’s lens may be dirty, which can cause the images to appear blurry or distorted. 

If the lens has become misaligned, it will prevent the projector from focusing correctly. In some cases, the lens may have been damaged or broken, resulting in an inability to focus properly.

In order to find the reason, visually inspect the lens or clean it if necessary. If the lens is misaligned, you can try adjusting it manually until it is correctly positioned. 

However, if the damage is too extensive or you are unable to correct the issue yourself, you may need to seek professional help.

2. Input Source Not Compatible

This issue with your projector can be due to the input source not being compatible. It’s important to make sure that your projector is connected with an input source that is compatible with the device. 

If the input source does not match the specifications, it will cause the image quality to be degraded and also prevent proper focusing of the projector. 

Other issues such as poor color or resolution can also occur due to an incompatible input source. 

In addition, when a connection between a laptop and your projector is established, it’s important to make sure that both have similar display settings for the image quality to be optimal. 

3. Projector & Screen Not Aligned

If your projector and screen are not properly aligned, the image may appear distorted, blurry, or off-center. 

The problem is often caused by either the projector or the screen being out of alignment. If the projector is too close to the wall or if it isn’t level with the floor, its image will be distorted; 

Similarly, if the screen isn’t straight or is tilted at an angle, then it won’t show an accurate representation of what’s being projected. 

This can make images look blurry or stretched out in certain areas. So, it’s essential to ensure that both our projector and screen are properly aligned. 

You can do so by checking that your projector is perpendicular to the wall and make sure that it’s level with the floor. 

Also, make sure that your projector is set at a reasonable distance from the wall (not too close) so that its image doesn’t become distorted. 

As for your screen, make sure that it’s straight and not tilted at any angle. You might also need to adjust its height so that it’s at eye level when you’re sitting down in front of it. 

You should also check that there aren’t any obstructions between your screen and projector which could be causing interference with the image quality.

4. Inappropriate Distance from Screen 

One of the most common causes of a BenQ projector not focusing properly is an inappropriate distance from the screen. 

If the projector is too far away from the projection surface, the projected image will be distorted and out of focus. 

Likewise, if it is too close to the surface, it may project an overly large image or be unable to reach focus at all. 

The proper distance for optimal projection clarity depends on the model of your particular projector being used. 

Generally speaking, most models require a set-up that places the lens at 1.6 – 2 times the diagonal length of the projected image. 

So, you should keep adjusting the distance in small increments until you achieve a clever image on the screen. 

5. Uneven Projection Surface

Uneven projection surfaces can cause your device not to focus. This is because the projector’s lens must be perfectly aligned with the surface in order to accurately project an image. 

If the surface is uneven, the lens will not be able to focus on any specific area, resulting in a distorted or blurred image. 

It should also be relatively flat and free of obstructions such as furniture or objects that could interfere with the projector’s alignment. 

You should ensure that your projector is mounted securely and correctly so it does not shift during use.

6. Incorrect Resolution Settings

Sometimes incorrect resolution settings on your projector lead it to the focus issue. The most common issue is that the projector is set to a resolution higher than what the source device supports.

This issue can cause images and text to appear blurry or not in focus. You can fix it by checking the settings on both your projector and your source device to make sure the resolutions match. 

If they do not match, you may need to adjust them so that they do align. You can also try resetting the device’s settings back to its factory defaults; this will often resolve any focusing issues. 

7. Factory Reset 

If your BenQ projector is not focusing properly, a factory reset may help. A factory reset will restore the projector to its original settings and can be done in a few steps.

In order to reset, unplug the power cable from the wall socket and then press and hold both the ‘Power’ button and ‘Menu’ button on the projector at the same time for 10 seconds. 

This will initiate the factory reset process and all of its settings will return to their factory defaults.

Once you have successfully completed this step, plug the power cable back into the wall socket, turn on your projector, and check if it has been properly focused. 

If it still isn’t focusing properly, try repeating these steps once more or contact a technician for assistance.

8. Update Firmware

An outdated firmware version of your projector as another cause for its faulty focus. Updating the firmware on your BenQ projector is an easy way to ensure it is running optimally. 

It is important to keep your projector up-to-date as it will ensure that all the latest features and bug fixes are included. 

To update the firmware, you will first need to download the most current version of the firmware for your projector model from the BenQ website. 

After downloading, connect your projector to a computer or laptop via USB and open the BenQ Update Tool app. 

Follow the instructions within this app to install the updated firmware. Once completed, restart your projector and check that it is focusing correctly.

9. Contact Manufacturer

If your projector still is not focusing properly, the best option is that you should consider contacting the manufacturer directly. 

Doing so can help diagnose the issue and provide you with a solution that can help restore your projector’s normal functioning. 

You should also be prepared to answer any questions they may have regarding when and how the issue occurred. 


How can I improve the quality of my projector image?

You can improve the quality of your projector image, by focusing the lens and adjusting brightness, contrast, and color settings. 

You may also need to clean the lens or move the projector to a better location. Additionally, use higher resolution content if available for a clearer picture with more detail.

Will the cold environment harm my projector?

Colder temperatures can potentially affect the performance of your projector. It is best to store your projector in a moderate environment with temperatures between 32-95°F (0-35°C).

 Lower temperatures may cause components to become sluggish or stop working, while higher temperatures can reduce lamp life. 

Therefore, it’s important to keep your projector in a consistent temperature environment for optimal use.

Why are the edges of my screen blurry?

The edges of the screen may be blurry due to an incorrect focus adjustment. You can try re-focusing the projector lens and checking that your image size is correct for your projection surface. 

You can also adjust brightness, contrast, and color settings for a clearer picture with more detail.
