Re: ADV7842 : CP VGA detection

Hello Guenter

 

I would like to identify the two reduced blanking mode : 1920x1200@60hz and the 1600x1200@60hz.

 

But this two mode produce the same result for STDI_BL and STDI_LCF and with experience the STDI_LCVS is never the same on different video sources.

And the Hs and Vs polarity is the same.

 

How to determine the right mode ?

 

thanks
