How to Fix Blurry Epson Projectors?

How to Fix Blurry Epson Projectors?

Whether you’re preparing for an important board meeting or you’re setting up your home theatre, the first thing you should do is make sure that your projector is in focus.

Blurry projectors can cause eye strain and headaches, and they’re downright unprofessional. However, when trying to fix the dials on your Epson projector, it can be confusing to decipher all the variables to adjust. 

While adjusting the focus dial is an important part of the process, you also have to think about lens cleanliness, positioning, keystone correction, and image quality.

This article teaches how to adjust focus on your blurry Epson projector to achieve sharp images, videos, and presentations.

How do I make my projector clearer?

1. Adjust projector focus

What is the focus?

The most straightforward way to improve blurry projector image quality is to adjust focus using the built-in focus adjustment dial.

Epson printers have a physical adjustment ring around the lens and twisting it will adjust the focus by moving the components in the lens itself. This shift in distance between lens components narrows or expands the projected image.

Most fuzziness issues are mismatches between the n where the screen is and where the screen is in focus.

How do I adjust the focus on my Epson projector?

  1. Turn the projector on and wait at least 20 minutes before adjusting the focus ring to move the beam where image quality looks good. 
  2. Using the control panel or remote control  is also a convenient way to adjust lens focus. Press the Esc button once the image is clear.

2. Check the lens for dust, dirt, and condensation

Clean Your Projector Lens

If some parts of the image are focused, but small portions are fuzzy, then the issue is with the lens itself. This is also true if the entire image doesn’t come into focus when you adjust focus adjustment.

The lens is where the light beam comes from, so any obstructions like dust, fingerprints, or moisture can lead to image distortion.


Fingerprints are the main culprit for the collection of dust on projectors. However, dust can also find its way onto the lens, especially if it’s left outside a protective case.

Dust can also enter the lens if it’s been disassembled.


When stored in a garage or attic, temperature changes can cause lens condensation. Bring the projector back to room temperature to remove the moisture naturally.

Here’s how to properly clean projector lens:

  1. Turn off the projector and allow it to cool for 20 minutes.
  2. Use compressed air or a manual lens blower to remove debris. Keep the blower upright and spray in short bursts.
  3. Clean the projector lens in a circular motion with a lens brush .
  4. Gently wipe the lens with lens wipes  or microfiber cloth in a circular motion.

3. Change the projector position relative to the screen.

Projector Alignment

As you move a projector further away from the screen, the larger the projected image will be. Throw distance refers to the distance between the “thrown” image on the screen and the screen. 

There will always be a distance where the image looks clearest. 

Using the focus dial is an easy way to adjust without moving the entire device or the screen, but if the projector is a few inches off in positioning, you will have to consider moving it.

What is the best throw distance for a projector?

Once your projector is in the centerline, it’s time to adjust the distance from the screen.

 Your Epson projector will have a recommended distance from the screen, so make sure to check the user manual.

Most projectors today have an aspect ratio of 16:9, perfect for HD video projectors .

Just to give you an idea, here is the best throw distance for Epson projector screens with a 16:9 aspect ratio:

Screen size (inches)

Minimum and Maximum Projection Distance (inches)


100 to 109


125 to 137


151 to 165


189 to 206

4. Adjust keystone correction.

Other times, you’ll have problems finding the centerline of your projection screen.

Keystone correction is essential to fix issues with a projector installed off-center through vertical and horizontal adjustment.

Horizontal adjustment

Projectors mounted off-center will have a skewed image with one half bigger than the other. 

Vertical adjustment

When projectors are positioned at an unexpected angle that’s too high or too low, you can compensate with vertical keystone correction to fit the image on the screen.

  • To adjust vertical or horizontal keystone correction, access the dials through the control panel. 
  • Increase or decrease the correction factor until the image fits well on the screen with no distortions.

5. Adjust image sharpness and/or resolution.

After making the above adjustments, it’s time to improve image quality through sharpness and resolution settings.


The Best Sharpness settings for projectors and TV

Your projector’s sharpness refers to the contrast and clarity of the thrown image. If the image looks too vibrant or too washed out, adjust sharpness through the Epson projector settings.

You can use test patterns  to increase or decrease sharpness so that images are crystal clear and razor-sharp.


Epson Projectors | Importance of Projector Resolution

Projectors are designed to project a certain resolution, but when you connect through HDMI, you’ll need to set the right resolution so your laptop or computer knows what size the image should be.

Most computers/laptops will automatically choose the highest resolution for the projector, but you can change the target resolution through your computer’s display management settings.


Lens focus adjustment

Blurry video output can be confusing to fix because of all the variables to think about.
