LCD LVDS interface

I thought I would try the LVDS interface board available here
So I created a new entry in the S.Board source so that I could add the details for the LCD panel I have available.
I made the extra entry similar to the entries for the Pandora/Touchbook.
The LCD is 18BBP and 1024 × 768.(LTN141X8-L02 is the model no.)
I have tried various pixel rates ETC but all I get on the LCD is lots of lines.
Could anyone give me any pointers as to timings that might work ?

Cheers

PS
Vsync 60 Hz
HSync 48.3 Khz

The datasheet lists it as expecting a typical pixel rate of 65MHz, so…

VSync of 60Hz → 1083333 pixels/frame
HSync of 48.3kHz → 1345.7 (1346?) pixels/line
1083333/1345.7 = 805 lines/frame

So try making sure the horiz front/back porch & sync values total 322 (1346-1024) and that the vert front/back porch & sync values total 37 (805-768). The datasheet doesn’t seem to list the minimum vsync/hsync timings, so just pick a number out of the air for those ;) You might also need to mess around with the invert HSync & invert VSync flags. I think you can safely ignore the DSI_BPP, DSI_LANES, ACBias_freq and LCDType settings (e.g. leave them as they are).

Good luck!

Thanks Jeffrey.

I am now getting different lines !!
The lines on the display are scrolling, at a speed and direction dependant upon the content of the screen (the HDMI works at the same time).
If it is a normal desktop, then the lines scroll down.
Pressing F12 and they scroll up.
Open an !Edit window full screen (white background) and they stop scrolling.

I have tried with HSync and VSync inverted with no difference.

Is there a limit to the H and V sync widths ?
I have tried both upto 5.

Thanks
