Notes:
➀ W = Width (number of modules wide), H = Height (number of modules high).
➁ Max Loading is based on a typical receiving card capacity (DH436: 512×384, DH3208: 512×512).
➂ Typical Layout means standard installation width × height.
➃ Alternative Layout refers to common cabinet arrangements in double-width or larger screen builds.
➄ NovaStar DH series, such as DH426, DH7516, DH7516N, DH7512, DH7508, DH418, are super flexible. They have HUB75E ports built-in and work with almost any HUB75E or HUB75C module. Compatibility headaches? Mostly gone with these.
➅ Want higher brightness, refresh rate, or grayscale? You usually can. Just drive fewer modules across the width than the max shown here. Less load often means better performance.
