We talk a lot about monitors around here, but we rarely come across one as unusual as the Dell P4317Q. This 43" 4K monster is the latest addition to Dell’s Professional display series. It comes with a robust set of ports: a standard DisplayPort 1.2 input, a Mini DisplayPort 1.2 input, two HDMI 1.4 inputs, even a VGA connection. It’s also equipped with four USB 3.0 ports, a headphone output, and an RS-232 serial port for "remote management." Then things get really weird. Dell says the P4317Q can operate as a standard 4K display, or as four independent 1920x1080 displays from four inputs.
Dell doesn’t go into much detail about how the four-input magic works, except to say that it requires Dell’s Display Manager software. Display Manager also allows the user to zoom in on a single display and rearrange displays. It’s not clear whether the software needs to be installed on all of the input sources. Since Display Manager is only compatible with Windows, requiring every host to have the software would limit the headlining feature of the device. Dell says the P4317Q needs a KVM switch, too, but it's not clear whether basic interaction with the split display requires one.
The P4317Q comes with Dell’s 3-year warranty. Dell sweetens its coverage on this display with the company’s Advanced Exchange and Premium Panel Guarantee, which allows you to get a warranty exchange if there is even one stuck pixel. The 43" four-input magic doesn’t come cheap, though. Dell has the P4317Q monster listed on its consumer site for $1,349.99.
