Getting the perfect image quality

This page will help you achieve the best possible image quality with the Bionic Display™ in your Varjo headset.

Bionic Display™

Varjo headsets feature the Bionic Display™ that lets you see virtual reality with the same clarity as the real world.


The highest and most intense resolution is in the center of the display, also called the “focus area.” This is similar to how the human eye works: you can see what is happening in the periphery of your field of view, but your focus is on what’s right in front of your eyes.

Turn your head to see the environment around you in the highest resolution.



Adjusting the headset lenses

Varjo headsets can automatically adjust the position of the lenses based on your interpupillary distance (IPD). In Varjo Base, the setting is found under the Headset tab and Automatically adjust interpupillary distance. The setting is enabled by default. We recommend that you keep the setting on for optimal comfort while viewing.

Please note: Varjo headsets work best for people whose interpupillary distance is between 61 and 73 mm. Those with smaller or larger interpupillary distance may not be able to see the content in the highest possible visual quality, or they may feel discomfort when using the headset.

The headset adjusts the lenses briefly every time you put the headset on. You may hear a short buzzing sound during the adjustment.

Tip: The automatic adjustment can sometimes fail if the headset is not positioned well and can’t detect your eyes. Also, frequent blinking may cause the adjustment to fail. To get an optimal reading of your eyes, press the System button and start the Headset positioning guide. In Varjo Base, navigate to the Headset tab and Headset positioning guide. The headset will readjust the lenses while the positioning instructions are displayed.

You can switch off the setting in Varjo Base if the automatic adjustment does not work for you. Even though the headset has been designed to work with most eyeglasses and contact lenses, the automatic adjustment may not work due to special eyeglasses or other medical conditions that impair your vision.



Positioning the headset for optimal viewing

The Bionic Display™ is a precision tool; seeing contents in the highest possible visual quality requires that the headset is precisely positioned over your eyes. Optimal positioning is different for every individual as it depends on the shape of your head and eyes. Eyeglasses can also affect optimal positioning.

Whenever you plan on working in a virtual environment with rich visual details, we recommend you check that the headset is positioned correctly using Varjo Base. If the headset is not positioned well, straight lines in the virtual environment may appear discontinuous or curved as they travel from the edges towards the center of the display. You may also notice blue or red halo colors on the edges of light-colored objects.

To quickly launch the headset positioning guide in Varjo Base, navigate to the Tools menu and open Headset positioning. Alternatively, navigate to the Headset tab and select Headset positioning guide. While the positioning guide is displayed, the device will also adjust the lenses to match your interpupillary distance.

You can set the headset positioning guide to appear automatically every time when you put on the headset. Go to the Headset tab in Varjo Base and enable Automatic headset positioning.


The graphics show four lines extending from the center of the display towards the edges. Looking closely, you will see that each line consists of three thinner lines.

Carefully observe the thin lines in the four areas highlighted with blue circles. These are the intersections where the high-resolution focus area meets the lower-resolution peripheral area. When the headset is positioned correctly, the lines will appear continuous in all four areas. If the lines appear broken, blurred, or bent, try moving the headset to improve the image. The second image illustrates an example of good and bad positioning.

After you have found the optimal position for the headset, make sure to adjust the headband so that the headset feels stable and stays in place.



Display blending

The focus area at the center of the Bionic Display™  features human-eye resolution, while the surrounding peripheral area is rendered in lower resolution. In Varjo Base you can choose how the two areas blend together.

In the Headset tab, open Display blending. Select Smooth: Seamless transition to seamlessly blend the focus and peripheral areas together by decreasing the image resolution towards the outside edges of the focus area. Sharp: Maximum resolution and contrast maximizes the area with the highest resolution. Note that selecting this option will make the border between the two areas more noticable.



Motion Prediction

Varjo Base can smoothen the movement of virtual objects in your application by predicting their motion. If objects in your scene are moving erratically, navigate to the Headset tab and Motion Prediction.

The default option is Enabled if supported, which enables the feature for those applications that support it. You can also enable or disable the feature for all applications. We recommend trying out the different options to find the one that works best for your application.

Please note that enabling Motion Prediction may introduce a small loss in performance.
