Use a slim raceway painted the wall colour, or an in-wall kit with recessed boxes. Any extension of mains wiring should be done by a qualified electrician.

OLED panels can retain images if one picture is shown at high brightness for long periods. LCD-based art displays are far less susceptible. Rotation and sleep schedules reduce the risk.
