DISPLAYCONFIG_TARGET_PREFERRED_MODE

構造体

サイズx64: 88 バイト / x86: 80 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド	型	サイズ	x64	x86	説明
header	DISPLAYCONFIG_DEVICE_INFO_HEADER	20	+0	+0	デバイス情報要求の共通ヘッダ(DISPLAYCONFIG_DEVICE_INFO_HEADER)。
width	DWORD	4	+20	+20	ターゲットの推奨表示幅(ピクセル)。
height	DWORD	4	+24	+24	ターゲットの推奨表示高さ(ピクセル)。
targetMode	DISPLAYCONFIG_TARGET_MODE	56/48	+32	+32	推奨される映像信号モード情報(DISPLAYCONFIG_TARGET_MODE)。
