Extended Mode Not on Dropdown?

I have pimax mode and video mode to choose from. Extend or Extended mode does not exist for me.

Video mode is more or less extend mode.

1.1.92 & older had several modes the 1.2.x series combined several modes into pimax mode

I’m trying to use extended mode since i heard pimax mode was only in 1080p. Is Video Mode 4k/2k?

Pimax mode by default runs qhd (1440p) what folks been calling 2k

In PiMax mode accepts fhd n qhd it then uoconverts to uhd (4k)

In video/extend the headset is seen as reg display & resolution set in display properties
