These commands can be used for discrete switching of the listed inputs. To access the s-video input, use the ASCII command 2 followed by ASCII command 1 to switch to the composite input and then cycle to the s-video input. Likewise, to access the DVI input, use the ASCII command G followed by ASCII command 1 to switch to the HDMI 2 input and then cycle to the DVI input. There are currently no discrete commands available to immediately access the s-video and DVI inputs.
