description The invention relates to a method for monitoring vehicle-mounted LVDS (Low Voltage Differential Signaling) link. The method comprises the steps that a processor generates a low frequency pulse signal, the low frequency pulse signal replaces a data bit in a digital RGB (Red Green Blue) video signal parallel interface, and then the low frequency pulse signal is modulated into the LVDS link together with a video signal for transmission; and when a far-end LVDS chip separates the pulse signal and outputs an intelligent device to realize monitoring after decoding the video signal, the intelligent device informs the processor to implement corresponding treatment in the event of not receiving the pulse signal within specified time. By the adoption of the method for monitoring the vehicle-mounted LVDS link, the abnormalities of a vehicle-mounted display system can be effectively monitored; a vehicle-mounted host is enabled to monitor the working status of the LVDS link in real time; and therefore, the problem that as
