Other Parts Discussed in Thread: SN75LVDS83B
Hi. We are using the two-chip solution of TFP401 and SN75LVDS83B to convert DVI input to LVDS output. We get a and LVDS video signal that is viewable on our LCD panel, but the image (color) is messed up. “True” Red, Green, Blue, Black and White all seem to be relatively okay, but all other colors are very incorrect, with rugged lines rather than smooth color gradients. The produced image is almost like a combination of too low of bit depth along with incorrect color mixing (for lack of a better explanation). Also, the text is not crisp.
I have attached a PDF detailing the issue. Pictures as well as circuit schematic and layout is included. Could you please provide some assistance in resolving this video issue? Thanks.
