Comentários

Indica MonitorsSameDisplayFormat se todos os monitores reconhecidos atualmente pelo sistema operacional estão usando o mesmo formato de cor de pixel.

Os formatos de pixel definem a estrutura de dados usada para codificar informações de cor e luminosidade do pixel. A PixelFormat enumeração indica um conjunto de formatos de cor de pixel padrão. Os valores de pixel podem ser codificados em uma variedade de formatos, com intervalos de valores de cores diferentes e precisões de bits e posições diferentes de bits em uma estrutura de formato de dados de pixel.

Observação

Duas exibições podem ter a mesma profundidade de bit, mas formatos de cores diferentes.
