I used a 4K player connect to the ADV7625 Demo Board RXA,and set working mode is Splitter mode,but just connect TXA to SONY TV(support 4K).I down load commands as follow:
1. Route c txa
2. Route a txa
And then you can see TV flash Snowflake,just 2s return OK.But set the Board working mode is Cross ,this problem is almost no.
