We are using the ADV7619 in a custom design.  We test at a wide range of resolutions, and we are seeing an intermittent issue at 1600x1200P60 with a 1m input lead. The issue is not seen with a 2m lead however, so there is a suspicion that it might be an equalizer issue.  It isn't clear how to select the equalizer for different resolutions.  In this case should I set it for "Pixel Clock < 170 MHz" 576[ip]  (1600x1200P60 is 162 Mhz) or for 1080p60 (greater number of lines and a faster Pixel clock)?

Best Regards,
