1920 x 1200 required for HD1080 video SDI formats.
1920 x 1200 recommended for 2x resize display of NTSC and PAL SDI formats. 1280 x 800 recommended for HD720 video SDI formats. Please note that few, if any, DVI-D displays support 720p50. 2560 x 1600 required for 2K feature film formats. |
| Resolution via HDMI | The HDMI input of a display must accept either: • 1920 x 1080 for HD1080 video SDI formats or • 1280 x 720 for HD720 video SDI formats Please note, that the native resolution of an HDMI display will often be less than full resolution HDTV, even if the display is rated to accept HDTV signals. This is a physical limitation of the display itself and full-resolution HDMI displays, or DVI-D displays, should be considered if pixel for pixel video is required. Please also note that only a small percentage of HDMI displays support 720p50. |
