Hello all, This is kind of a long shot but I thought I would see if someone here happen to know. I'm working with a ComExpress() which give me a LVDS video out.

Sep 13, 2010 - Connection table ADA-LVDS-DVI to JILI interface. The ADA-LVDS-DVI is a converter module from LVDS (Low Voltage Differential.

I need to convert this to DVI. I bought an off the shelf LVDS to DVI converter() and it worked perfectly. Then the ComExpress() we are using changed and the converter no longer worked. The weird part about this is I have some flat panel displays which use the LVDS directly and they work for both modules. Harman kardon isub 2000 windows driver. So I tried a different LVDS to DVI converter(, ignore the fact that it's 24-bit.

I confirmed that it will work besides giving a washed out effect) This converter worked on the original ComExpress but did not work on the new one. I've tried all the graphics BIOS options on the ComExpress and none of them work. I should note that all the LVDS signals and displays are 18-bit.

I scoped the LVDS signals of the first and second ComExpress and noticed that the one that doesn't work has lower amplitudes than the working one. Attached are the scope measurements with no changes besides the ComExpress used(I even didn't move the probe cables). I probed the DVI port and it is clocking and sending data(I can't easily validate that data though). That's where I'm at now. I'm not sure what could be causing the problem. Does anyone have experience with any of this or have an idea of what could cause it?
