In practice, it very much is. My monitor is at 80 degrees field of view, so the headset is only directly representing about 1440p worth of pixels, but with the passive temporal upscaling of your heads constant micromovements meaning a completely different set of pixels is seen each frame, I tested and 4k still looks notably clearer than 1440p on it, so I use 4k.

The difference from every other desktop viewer to Virtual Desktop is night and day because of it.
