Abstract: The present invention provides a display control method and system, and a display device. The method includes acquiring a status value of a display buffer; comparing the status value of the display buffer with a preset warning value of the display buffer; and adjusting a value of a depth of outstanding bus commands according to a comparison result. In the embodiments of the present invention, a status value of the display buffer is compared with a preset warning value of the display buffer, where the status value of the display buffer reflects a change to a current load; it may be determined whether a status value of the display buffer corresponding to the current load is normal according to a comparison result; and a value of a depth of outstanding bus commands is adjusted accordingly, effectively resolve a data real-timeness issue, and ensure that an entire system efficiently runs.
