Review on Adjustable Samsung LF24T452FQNXGO 24 Inch Computer Monitor - 1920X1080P, 75Hz, Flicker-Free, Height Adjustment, USB Hub, Wall Mountable, HD, IPS, HDMI by Sol Nuttbrock

The instructions and illustrations that came with the unit are in small print in off-white ink, so for me the "tools needed" were a magnifying glass and a scanner, which enlarged them. Faced with these issues, building from scratch is instinctively easy. DO NOT pull the cotter pin while leaning over the product; the spring-loaded standpipe/monitor CAN hit a person in the face! First I got a message on the screen that "no signal". It's not entirely clear that the "scroll button" controls not only left/right/up/down registration, but also input selection - HDMI 1 / HDMI 2, etc.
