More info on Dell's new P4317Q Ultra HD monitor has surfaced. The display size is so big that Dell calls this a Multi Client monitor, the monitor uses a 42.51” IPS panel, likely an LG Display model. 

The panel boasts a 3840 x 2160 (‘4K’ UHD) resolution, with a pixel density of just under 104 PPI. Dell touts the ‘Multi-Client’ capability of the monitor, with PiP and PbP allowing 4 devices to output to the screen simultaneously.

It has a 60Hz refresh rate, 1000:1 static contrast ratio, 10-bit colour output (likely 8-bit + FRC dithering) and 178° horizontal and vertical viewing angles. An enhanced phosphor WLED backlight is used to offer excellent sRGB colour space coverage but no support for wide colour gamuts.

An 8ms grey to grey response time is specified. The monitor includes 100 x 100mm and 200 x 200mm VESA holes for alternative mounting. The ports include; DP 1.2, mDP 1.2, 2 HDMI 1.4 ports (with MHL), VGA, 4 USB 3.0 ports (plus upstream), a 3.5mm audio input, 3.5mm audio output and RS232 port. Two 8W speakers are also included, which should provide fairly decent sound output.

The monitor is listed for $1350 / 1050 EURO on Dell’s product page and appears to be intended as a B2B product and may not see the usual wider retail availability.
