A monitor arm clamps or bolts to your desk and holds one or more screens on an adjustable VESA mount, so you can set exact height, tilt, swivel and depth while freeing up the space a stock stand takes. It is one of the cheapest upgrades that fixes neck strain, tidies a dual-screen setup and reclaims your desktop for gamers, traders, developers and office users across South Africa.

Choose by four things: how many screens (single or dual), your monitor's VESA pattern (75x75mm or 100x100mm on most panels, 200x100mm or 200x200mm on large ultrawides), the weight capacity per arm versus your monitor's actual weight, and the fitting - a desk clamp for edges up to about 45mm, or a grommet mount through a drilled hole. Gas-spring arms re-balance smoothly at any height; spring-loaded mechanical arms cost less and suit lighter screens.
