Dell's latest monitor is a doozy. The Dell 43 Multi-Client Monitor (P4317Q) is a 4K, 43-inch beast that acts as if it's four displays squished into one. When shown on a single screen, the displays are borderless, but users are able to swap any of the clients to full-screen mode, too. The entire monitor has a max resolution of 3840 x 2160 at 60Hz, a response time of 8ms, two 8-watt speakers and a USB 3.0 hub with four ports.
