DS90UB948-Q1: display abnormally with 948

Part Number: DS90UB948-Q1


Hi team,

Recently my customer had an issue of abnormal color display . They use 947 and 948 to transmit video signal and the display works normally. But when they don't use 947 and connect to 948 directly, the output displays color abnormal. The customer has tried to change VESA/SPWG/OLI to JEIDA. But the display works still abnormally. Could you give some advice about how to check the configuration? Or which register need to check?

Does 947 and 948 have any self-test mode?   Could you share any material with us?
