Why buy two small monitors if you can buy one large one? That's what HP wants you to consider with its S430c, a 43.4-inch, 4K monitor that gives you the experience of using two WUXGA screens in a single monitor. About that screen: it's gorgeous. The 43.4-inch panel is bright, vivid and detailed, perfect for watching movies or getting work done.

The ultrawide screen isn't the only trick the S430c has up its sleeve. You can connect two Windows or Mac laptops or desktops to the S430c and view them on each side of the S430c. Better yet, software wizardry lets you control the two systems with a single cursor and keyboard, and you can even transfer data from one to the other using copy/paste or drag-and-drop.
