We are using ADV7441ABSTZ for DVI input (Port A).


We tried the attached register configuration for DVI input at SXGA resolution from the script provided in the Design support files for ADV7441A in Analog devices website. (ADV7441A_ADV7441A@_ADV7441AVDP_ADV7441AHDMI_ADV7341-VER.MB3.0.TXT file of ADV7441A Design Support Files) .

We are seeing only the blue screen(internal test pattern) on the display.

Please find the attached settings.

Please let us know if the register configurations are fine.



Thanks & Regards,
