Hi Team,
Now customer is experiencing the following problems when using TMDS181, please help to check his drawings and layout, and provide some suggestions.
1. When he uses NVIDIA's GTX 1050/1060/1080 graphics card at the resolution of 4K*60hz, a flickering black screen appears at a certain interval, but this problem does not occur in case of 4K*30hz.
2. This problem does not occur when using the ATI graphics card at 4K*60HZ with the same connection.
3. If he changes the VSAJ resistance from 6.98K to 4.7K, the situation is improved. What aspects will be affected by this change, and will it affect EMC?
Attached is Silk screen printing and layout of front adapter plate HDMI181pcb.pdf and Schematic diagram of front adapter plate hdmi181_A2.pdf
Thanks!
