TFP401A: RGB output abnormally

Part Number: TFP401A
Other Parts Discussed in Thread: TFP401, TFP410

Hello,

Our customer meet a question about TFP401&TFP410. When the procedure is DVI source---TFP401----FPGA---TFP410. He found that the output data from FPGA is not the same as the normal RGB color space. For example, if the input DVI is black image,  QE[23:17]=1 and others are 0. But if he removed FPGA, as  DVI source---TFP401----TFP410 , it could normally display.

So could you please help to analyze if it could display normally with FPGA, how to configure the TFP401 &TFP410?

Best regards

Kailyn
