About

DisplayMath is a free TV and monitor comparison tool. See screens to scale, compare how large they look from your seat, and change viewing distance for each display. Compare dimensions, horizontal and vertical field of view, PPI and pixels per degree.On a supported iPhone, preview a screen panel at actual size on your wall with browser AR, without installing an app. TV size and mounting-height tools help plan the setup.The calculators and AR previews are free and need no account. The AR model shows the screen panel; check the product’s bezel, stand and mounting hardware separately.
