Hi Dave ,


We are using ADV7441A in our design. We are referring scripts which are available in the design support files page for ADV7441A in the FAQ section of this forum. For UXGA resolution configuration provided in the script file "ADV7441A_ADV7441A@_ADV7441AVDP_ADV7441AHDMI_ADV7341-VER.MB3.0".

(#GR UXGA 1600X1200##:RGB 1600x1200 _@ 60 162MHz Autographics Out through DAC)/. Its working properly when we provide the UXGA input. But when we configure the chip for SXGA resolution (##GR SXGA 1280x1024##:RGB 1280x1024 _@ 60 108.000MHz Out through DAC:), sometimes It will take the input and sometimes only default value (blue color)  will be displayed. Can you please check and let me know the reason for this.


Thanks & Regards
