Did you hear that noise? It's HP dropping the gauntlet on the mixed reality scene with its new Reverb headset, which delivers an impressive 2160x2120 resolution per eyeball.

That is a big leap over the 1440x1440 resolution of HP's first-generation mixed reality headset, with the Reverb offering more than twice as many pixels overall. It's also ahead of the original Oculus Rift and HTC Vive, the best VR headsets, both of which use 1080x1200 displays, and it even beats the 1440x1660 resolution found on Samsung's Odyssey and HTC's Vive Pro.
