Difference 1) Waveguides
One of the main differences compared to the M400 is that the Vuzix has now added its revolutionary Waveguide optics to the M4000.
What are Waveguides?
Waveguides is a technique that makes it possible to make the display transparent, such as with glass and plastic. As a result, the virtual image is projected onto the transparent display, but the user can see through the glasses more easily than when this is not the case. As a result, the display is no longer in the way and the user has an enlarged viewing window. While other technologies display an opaque image, Waveguides are transparent. This means that the Smartglass does not have to be removed to perform other tasks.
Compared to the M400, which uses an OLED screen, the Waveguide technique also increases the resolution that is perceived. The M4000 has a resolution of 854×480 with the resolution of the M400 OLED screen being 640×360.

Difference 2) Improved ergonomic design
Comfort while wearing a Smartglass has always been a major focus at Vuzix in the development of the M4000. By replacing the opaque display of the M400 with the transparent Waveguide display of the M4000, the ergonomic design of the M-series comes into its own even better.
