VESA Mount Pattern and Weight Compatibility

Pattern match is necessary, not sufficient. A 400×400 TV on a 200×200 mount does not fit. A mount’s weight rating covers its own arm at full extension, but the pull on the wall fixings grows with arm length, so the wall needs its own check.

Calculation method

Pattern OK if both TV hole spacings ≤ the mount’s largest pattern. Weight OK if TV kg ≤ mount kg. Compatible if both pass.

Exact formula

OK if W_tv≤W_mount and H_tv≤H_mount and m_tv≤m_mount. Limits: no minimum mount pattern, no wall leverage of a full-motion arm, no stud or anchor strength, no dual-pattern adapters.

Frequently asked questions

Adapter plates?

They add leverage and often void ratings. Prefer a mount that natively fits.

OLED vs LCD mass?

OLEDs can be lighter but more fragile. Rating is still mass, not diagonal.

Dual VESA on the TV?

Use the pattern the mount supports. Measure the holes.
