This has been the case in PC VR for years. The Valve Index has a combined 4.6 MP at up to 144hz, with reprojection and motion smoothing so that the image still updates with head movement even if the application hitches. Or now you can get the Vive Pro 2 with 12 MP at 120hz. Or wireless oculus quest 2 with 7 MP at 120hz. The novelty would be a clear screen, or forward facing cameras, and a useful AR overlay.
