Blurry video using ADV7842

Using the ADV7842 for both DVI or VGA. When using VGA at 1024x768 @ 60Hz the

video is blurry to the point that it is hard to read text. We are using a

SN65LVDS93A to interface to our display. Placing a 22pF capacitor on the LLC

pin at the SN65LVDS93A part clears it up. This is a second stage prototype

which is Rigid-Flex, the first stage prototype was Rigid only and did not have

any issues. Do you have any ideas on what may be causing this, the DVI works

fine so it does not seem to make sense that a 22pF capacitor on the LLC pin

would clear this up.
