Not sure where else to turn so thought I'd try this forum for help. I have a surplus Motorola ML-910 ruggedized PC running Windows XP (32 bit) with an ATI Mobility X1400 graphics card (8.33-0661220m driver package). I want to hook to my Sharp LC-70LE732U via the VGA connector on the PC input of the TV. Upon connection, the PC graphics control panel properly recognizes the Sharp TV, but there is only a black display on the TV screen itself. Repeatedly cycling between CRT, LCD, and CRT+LCD via the Fn+F9 indicates that the PC is talking to the TV, but only a black screen is ever the result.

I've connected a different PC also running Windows XP, but with an ATI Mobility FireGLV3100 which works fine. I can find no later version of driver for the X1400, so am hoping that someone here has been able to get this configuration to work via some setting - either in the graphics card, or the TV or both. Any suggestions? Thanks in advance.
