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, you can find the setting to automatically adjust the lenses under the Headset tab and Automatically adjust interpupillary distance.

Automatic adjustment of the lenses is enabled by default. Your headset will adjust the lenses when you put it on, and you may hear a short buzzing sound during the adjustment. We recommend that you keep the setting enabled for optimal comfort while using the headset.

To adjust the lenses manually, disable the setting for Automatically adjust interpupillary distance and set the distance to match your eyes.

Varjo headsets are designed for use with a wide range of interpupillary distances. Those with a smaller or larger interpupillary distance may not see content in the highest possible visual quality, or may feel discomfort when using the headset.

Varjo headset model Supported IPD range
XR-3 and VR-3 59–71 mm
XR-1 Developer Edition, VR-2 Pro, VR-2, and VR-1 61–73 mm

Note that the automatic lens adjustment may fail if the headset is not positioned well and can’t detect your eyes. Read more about positioning your headset for optimal viewing.

Your headset will work with most single-vision eyeglasses, but the automatic adjustment may not work with special glasses or medical conditions that affect your vision. If the automatic adjustment does not work for you, you can disable the setting in Varjo Base.

Positioning the headset for optimal viewing

The Bionic Display™ is a precision tool; seeing content in the highest 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.

XR-3 and VR-3
Adjust the headset when you put it on to find a comfortable fit. The headset is correctly adjusted when it sits comfortably on your head, stays in place, and the image inside the headset is sharp.

If the headset is not positioned well, straight lines in the virtual environment may appear 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.

XR-1 Developer Edition, VR-2 Pro, VR-2, and VR-1
The headset positioning guide in Varjo Base helps you to position the headset correctly over your head.

To quickly launch the guide, navigate to the Tools menu and open Headset positioning. Alternatively, navigate to the Headset tab and select Headset positioning guide. You also can set the headset positioning guide to appear automatically every time you put on the headset. Go to the Headset tab in Varjo Base and enable Automatic headset positioning.

The headset positioning guide shows 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 image illustrates an example of good and bad positioning. Adjust the headset so that the lines appear continuous.

If the headset is not positioned well, straight lines in the virtual environment may also appear curved as they travel from the edges towards the center of the display. Additionally, you may notice blue or red halo colors on the edges of light-colored objects.

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.

Foveated rendering

XR-3 and VR-3

Foveated rendering uses the eye tracking functionality built into your headset to improve the performance of applications and produce a better virtual experience.

With foveated rendering, your headset can render fewer pixels in peripheral areas while maintaining the highest resolution in the center of your vision. The area with the highest resolution will follow your gaze so that you can experience the best possible image quality at all times.

Foveated rendering is calibrated whenever you put on the headset. Simply look at the calibration dot to start calibration. For best results, make sure to position the headset correctly when you put it on.

Note that foveated rendering is enabled only in applications that support the feature. Applications built for older headset models must be updated to use foveated rendering. For more information on upgrading your applications, see our Developer portal.

Display blending

XR-1 Developer Edition, VR-2 Pro, VR-2, and VR-1

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 noticeable.

Motion Prediction

The Motion Prediction feature in Varjo Base can smoothen the movement of virtual objects in your application by predicting their motion. This can be helpful if some objects are moving erratically.

To use Motion Prediction, 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. Note that in some cases, enabling Motion Prediction for applications that do not support it can cause unexpected visual effects.

We recommend trying out the different options to find the one that works best for your application. Using Motion Prediction may introduce a small loss in performance.

Compatibility render resolution

Running OpenVR and OpenXR applications in full resolution can be too demanding for some graphics cards. To improve performance, you can lower the image resolution in Varjo Base.

Navigate to the System tab and Compatibility render resolution, then select the desired resolution in the drop-down list. Lower values allow for the application to be run at a higher framerate at the cost of lower image quality. Restart your application to apply the new resolution.

Note that while you can also adjust the resolution of OpenVR applications in SteamVR, we recommend that you use the resolution settings in Varjo Base.
