Logitech is selling the Brio 4K Ultra HD webcam for nearly 40 percent off for Prime Day. It's the top Windows Hello webcam and a great everyday 4K camera too.

Most webcams are 720p and only a few MP. Logitech Brio 4K Pro Webcam offers unparalleled picture and video quality for a webcam. I would buy it for Windows Hello alone to upgrade a desktop.

We only spotted the first PC display with 4K HDR in December when LG tipped its 32-inch HDR display leading up to CES. Then at the trade show in January we saw HDR monitors from Acer, Asus, and Dell.
