Timing Table
• The following table includes all display modes that this AD board can support; The product does not ensure proper operation if the display mode is not in the table.
• The table has covered most of popular display modes, especially VESA standard definition display modes. It is possible to add special display mode into the table if customer offers the timing information and verified successfully by us.
• Not every application can apply to all modes in the table . It depends on panel , resolution and some key parameters.
• Most panels does not support 75Hz vertical refresh rate while the A/D board can support . Improper application out of panel limit range may cause the damage to panel.
• The best display performance can be shown only when the input display mode matches the panel resolution.
