Claim 19:
20. An information handling system, comprising:
a host processing system including a first graphics processing unit (GPU), a second GPU, and a Baseboard Management Controller (BMC); and
a Liquid Crystal Display (LCD) device including a memory device and a DisplayPort Configuration Data (DPCD) register;
wherein the BMC is configured 1) to determine that the first GPU is an embedded GPU and that the second GPU is an add-in GPU, 2) if the second GPU does not support a Dynamic Display Shifting (DDS) mode, then to provide a first indication to the LCD device that the second GPU does not support the DDS mode, and 3) if the second GPU supports the DDS mode, then to provide a second indication to the LCD device that the second GPU supports the DDS mode; and
wherein the LCD device is configured to retrieve a Panel Self Refresh (PSR) setting from the memory device and store the PSR setting to the DPCD register in response to the first indication, and to retrieve a DDS setting from the memory and store the DDS setting to the DPCD register in response to the second indication.
