Virtual reality voyages to space are all well and good, but Mars’ wow factor is nullified somewhat if it seems as though you’re looking at it through a fine mesh fence. That’s known as the screen-door effect, which is when the gaps between pixels are visible on a display - a major problem in VR, as those displays are plonked directly in front of your eyes. HP’s new Reverb headset goes some way to eliminating the issue, its 2,160 x 2,160 resolution a marked improvement on what we’ve seen before. Otherwise, the Reverb is a pretty by-the-numbers Windows Mixed Reality headset. You get a 114-degree field of view, spatial audio, inside out tracking and pre-paired motion controllers out of the box. And at just 1.1 pounds, it’s light enough to wear to space and back. Weirdly, the Reverb will be sold in two variants: a $649 Pro model, and a £599 Consumer Edition, which loses the Pro bundle’s .6m headset cable for the HP Z VR Backpack, and washable fabric face cushion. Both will be available from late April.
