Researchers at Nvidia have found a trick that solves the problem of users being able to see the pixels in their VR headsets. By using a “cascaded display” involving two LCD panels, the researchers found that they could quadruple the pixel density of the headset, making pixels invisible to the eye even at close range. The cascaded displays also have a faster frame rate, making images appear smoother, and a reduced brightness, which is not a concern for the displays in VR headsets.

Western Digital’s HGST subsidiary announced yesterday it is shipping a helium-filled, 3.5-in hard disk drive that has been more than 10 years in the making. The company says the new drive offers 50 percent more capacity than current 4TB drives and uses 23 percent less power and is 38 percent lighter. While pricing has yet to be announced, the company says the drives will “command a premium” based on the lower total cost of ownership. HGST plans to sell the drives to server and storage array manufacturers.
