There's "big" trouble for LG, which scored exclusivity on Apple Store for its UltraFine 5K monitor. A critical flaw in the monitor's design makes it intolerant to electromagnetic interference from devices as inconspicuous as home Wi-Fi routers. Apparently, the designers of the display forgot to give proper EM (electromagnetic) shielding for its electronics. When placed within 2 meters of a Wi-Fi router, the display begins to flicker, and when brought closer, the display even blanks out.

As an immediate workaround, LG advised customers to keep the display at least 2 meters away from a Wi-Fi router. Something like this could be tricky in a postmodern workspace such as a studio, where multiple MacPro workstations wired to such 5K displays are connected to the Internet over commercial Wi-Fi, with powerful >9 dBi antennae designed to spread signal to the far reaches of the office. LG maintains in a statement that this issue does not affect its other monitors.
