What is the optical zoom in the Audi A4's available virtual cockpit?

I'm interested in learning more about the virtual cockpit in the Audi A4. One feature that caught my attention is the optical zoom function. How does it work and what is the level of magnification it offers?

The Audi A4's virtual cockpit offers a 12.3 inch display with a resolution of 1440 x 540 pixels. Through the use of LCD screen technology and advanced optics, the virtual cockpit provides a clear and crisp image with a 20% larger magnification compared to traditional instruments.

In terms of the optical zoom itself, the virtual cockpit allows for a maximum magnification of 1.2x, giving drivers a closer and more detailed view of the instrument panel.
