If 4K wasn't taxing enough for your computer, Dell has an 8K monitor coming soon that will shame the best graphics cards. The UP3218K will be releasing in March or April for $4,999 and is a beast of a display.
The Dell UP3218K is a 32-inch 280 ppi monitor that can output 7680x4320 at 60Hz. It has a 178 degree vertical and horizontal viewing angle, 400 cd/m2 brightness, 1,300:1 contrast, and can output 100% of the Adobe RGB, sRGB, and Rec709 color gamuts.
The monitor has a slim 9.7mm bezel and comes with 2 DisplayPort 1.3 connections, 4 USB 3.0 ports, and 2.5mm audio out. HDR isn't mentioned, and more than likely isn't included. HDMI 2.1 will be supporting 8K video, and a cheap adapter will allow HDMI 2.1 output to stream to this device.
Dell is targeting the monitor at commercial uses where in-depth image zooming is essential. Photo and video editing, medical diagnostics, and oil and gas exploration, are all businesses that will benefit from this monitor's high fidelity. However, don't let the high-ceiling stop you from trying to game on it. Someone is sure to build a ridiculous rig to push this 8K behemoth.
