How To Reset Keystone Correction? (Epson, Optoma, XGIMI, BenQ, Sony, JVC)


Getting your projector screen to lay flat against the wall is an important part of setting up your home theater. An askew picture will make the image look wonky and distorted, and could completely ruin your viewing experience. 

Luckily, projector manufacturers have already thought of this and developed a solution. 

Keystone correction is a handy feature that positions the projector screen flush against the wall and is a total game changer for any projector fiend. 

But fine-tuning a unit’s keystone correction can be tricky, and sometimes you need to go back to square one and start over. 

How can you reset the keystone correction?

Epson

To reset your Epson projector’s keystone correction, press the remote control’s Menu button and open the Settings tab. Click on Keystone and select the Reset option at the bottom of the pop-up window.

Some Epson models do not have the option to only reset the Keystone correction. In this case, you must select Reset at the bottom of the Settings page to reset all picture settings.

To adjust the keystone correction on an Epson projector, you must either use your projector’s remote and settings, or the dedicated keystone correction buttons on your unit’s operating panel. 

If your model doesn’t have keystone correction buttons on the operating panel, use your remote to open the Keystone menu. 

There will be two sliders for you to adjust. The V-Keystone slider moves the screen forward and backward vertically, while the H-Keystone slider moves the screen horizontally. 

Adjust the sliders until you’ve achieved your desired picture settings. 

If your projector has Keystone buttons on the control panel, notice that the first one will adjust the top half of the screen’s angle, and the second will adjust the bottom half of the screen. Press both buttons accordingly until the screen is straight. 

Watch the video below to learn how to reset and adjust your Epson projector’s keystone correction.

Open the Main menu by pressing the Menu button on the remote. Click on Setup found on the bottom of the screen. Select Reset and press Yes in the popup window to confirm your choice.  

To adjust the keystone correction, go to Display on the Main menu page. If you want to use your projector’s auto-keystone correction feature, toggle Auto Keystone on. Note that this will only alter the vertical keystone correction.

Remember to select the correct Projection mode (i.e. how your projector is set up), as this will improve the auto-keystone’s accuracy.

Tips for Configuring a Projector’s Keystone Correction

Follow our suggestions below when configuring keystone correction. 

There’s no way around it, manually adjusting the keystone correction can be complicated. Thankfully, there are tips and tricks you can use to make your projector’s image as straight and flat as possible.

Use Your Unit’s Test Pattern 

Basic Circles & Grids Aspect Screen Test for TV, Monitors, Projectors and other Displays

Some projectors also have a built-in test pattern (a black and white grid) to help you ensure your screen is straight and not distorted. 

Use the test patterns vertical and horizontal lines as a guide to manually correct the auto keystone. 

Press the arrow keys and tilt the pattern until it’s straight and all the boxes are the same size. 

This test pattern also comes in handy when focusing on your projector! 

Turn off all ambient lighting to ensure you can see the grid properly. 

If your unit doesn’t have a built-in test pattern, fear not! 

You can find videos online, like the one below, which display grids and circles to help guide you. 

Pull up the image on your phone or laptop and connect them to your projector. Make sure the image is clear on your device, so it won’t appear blurry because of a poor internet connection. 

Ensure Your Projector Screen is Taught

Make sure whatever surface you’re projecting onto (a screen, sheet, etc.,) is completely smooth and taught. It will be extremely challenging to confirm that the image is straight and aligned if your screen is wrinkled. 

If you’re using a portable projector screen, make sure it’s positioned properly and is not tilted. 

Be Patient

Modifying a projector’s keystone correction may take some time, especially if you’ve never done it before. To ensure the most accurate results, go slowly and make small tweaks. 

Don’t worry if it looks wonky, that’s what the reset button is for!  

Wrapping Things Up

Knowing how to reset your projector’s keystone correction will undoubtedly come in handy, so it’s a good skill to have in your reservoir. 

There will always be trial and error involved in perfecting your screen’s keystone, but don’t lose hope! 

When possible, use your unit’s built-in test pattern or find one online. 

Make sure your projecting surface is smooth and clear of imperfections and don’t get frustrated if you can’t configure it correctly on the first try. It happens to the best of us!
