The sync signals go from the GFX card _to_ the display.

Maybe the LCD is unable to sync to the resolution or H/V frequency. Plug
in the CRT and try to get some status display on it. Many CRTs can
display a status page in the on screen menu with resolution and H/V
frequencys. Most likely you need to tune the U10 to the native
resolution of the LCD and 60 Hz refresh rate. Many U5 / U10 come up with
1152 x 900 and this may confuse LCDs as they only expect 1024 x 768 or
1280 x 1024.

Why are you trying to get some PCI VGA? You can add a UPA framebuffer
quite cheap too. I suspect it to be faster then PCI.
