ADV7441 VGA blurred(fuzzy, out of focus). worse at hi resolution.

When we render to a pc monitor the 7441 data in other modes it is flawless.

But, in VGA mode, even when using the auto detection modes the rendered pic is blurred.

This gets worse at higher VGA resolutions.

Is the YCrCb data presented the same in all video modes to the pixel bus?

Any ideas why we are seeing this?

 

We see this same performance even when using the register settings from the 1280 x 1024 60hz ADI script.

Has anyone else used these register settings successfully?

 

Thanks,

Fred Ziffel :-)
