TV mounting: forget the stud finder you saw on YouTube
Most TV-mounting advice online is written for North American timber-frame houses. UAE apartments and villas are built differently: exterior and structural walls are concrete block or poured concrete finished with plaster, while many internal partitions, especially in towers built after roughly 2005, are gypsum board on light-gauge metal studs. A timber stud finder is useless here. The professional method is a knock test first (block sounds dead, gypsum sounds hollow), then a magnet or metal-stud detector to map the studs at their usual 400 or 600 millimetre spacing.
On block or concrete, the job is straightforward: a hammer drill with a 6 or 8 millimetre masonry bit, nylon plugs matched to the screw, and the bracket pulls up rock solid. Expect 45-60 minutes for a fixed or tilting mount up to 65 inches, including unboxing, levelling and cable tidy-up. On gypsum, the calculus changes. A fixed mount for a mid-size TV can go onto heavy-duty toggle anchors spread across the plate, but a full-motion articulating arm concentrates leverage onto a few fixing points, and on gypsum that demands hitting at least two metal studs or, better, fitting a plywood backing board first. A technician who proposes screwing a swing arm straight into plasterboard with plastic plugs is telling you they have not done this long.
