The invention discloses a method for synchronously playing an ultra-large-resolution video on an LED screen, and the method comprises the steps that a media server is provided with a plurality of graphics cards, S11, a playing request is responded, a decoding module is called to start decoding, and a decoding process sends the decoded texture to a corresponding rendering process; s12, a rendering inquiry instruction is sent to the rendering process, so that the rendering process checks whether texture exists in a storage column of the rendering process or not; s13, receiving texture existence messages sent by the rendering processes, judging whether texture existence messages sent by all the rendering processes are received or not, and if yes, sending rendering instructions to all the rendering processes; and S14, receiving rendering completion messages sent by the rendering processes, judging whether the rendering completion messages sent by all the rendering processes are received or not, and if so, repeate
