Hi
I have a video output from my system which is not working very well.
There is an industrial PC motherboard with an LVDS output for TFT displays.
I have designed a converter PCB which creates a DVI output from the LVDS, and does the following:
I get some strange image error on the screen which appears to happen within a video line when the pixel color changes a littlebit. The display puts an extra bright pixel at certain color level changes, if the change happens in a horizontal direction. If it changes vertically then it displays it fine, which tells taht its a problem within a video line.
See attached image.
What can cause a problem like this?
