How the calculation works
V12 calculation: weightPass=tvWeight≤mountMaxWeight; diagonalPass=mountMinDiagonal≤tvDiagonal≤mountMaxDiagonal; overallPass=weightPass AND diagonalPass. This is the implementation rule for this calculator.
Worked example
Example: TV weight = 22 kg; TV diagonal = 50 cm; Mount maximum rated load = 50 kg; Mount minimum TV size = 50 cm; Mount maximum TV size = 50 cm. Result: Fits; Diagonal Pass = Pass; Weight Pass = Pass.
