Frame drops and jerkiness are observed with the TPG source with some test patterns generated by the TPG in the VCU TRD design
VCU QT: Green shade on DP when playing 4Kp30 HDMI/MIPI pipeline with SCD
Frequency: At random interval
Work-around: None
Frame drops observed with 8x1080p30 (7-HDMI-Rx + 1 MIPI) AVC serial use-case due to system level limitation

To reduce performance issues with 8x serial pipelines, please refer to chapter# 40 of Section VI: Appendices for IRQ Balancing scheme in PG252 [TODO: To be updated by 4th May, 2022].
2.2 Limitations
For playback in DP, video input resolution should match the DP's native resolution. This constraint is in support of the GUI. In the GUI if we allow a video source other than native resolution (by setting full screen overlay) then the graphics layer will disappear. To recover, the GUI user need to kill and relaunch the GUI app. To avoid this condition the TRD only supports video input resolution which is equal to the DP's native resolution.
