PLease help me play the matching game!

This is a pinout I got from Datalux for a 10.4" TFT touchscreen, apparently the same connector handles the video and the touchscreen. Can anyone help me identify what means what? I have a Earthvision PCI LCD card with a C&T 65550 chip. I have the data sheet for the card and the 65550. (I also have an SBC with a Silicon IMage SIL154 but that is another matter.

The PCI card data sheet shows the following pinouts on a 50-pin header: P0-P23 (though I note that P15 and P16 are separated by a ground), VDDSAFE 5VDC, +12 Safe, VEESAFE, VDDSAFE 3.3VDC, LP (HSYNC), FLM (VSYNC),SHFCLK, and a bunch of GND. What are VEESAFE and VDDSAFE?

The C&T 65550 chip which is on the PCI card has a "Panel Interface Group" which has the following "pinouts" : P0 through P15 (P16-P23 is on another section of the chip), DGND, IVCC, IGND, SHFCLK, M, LP, FLM, DVCC, HSYNC, VSYNC, DGND, ENAVDD, ENAVEE.

Below is the pinout for the display - is it as simple as hooking up po to po, FLM to FLM, etc.? Whats ACDCLK? Which ones do you think belong to the touchscreen part? Thanks again.

Usually its as easy as matching the two pins. I might be wrong, but the pinouts from that LCD make it look like a monochrome LCD because there is no RGB pins.. just DL and DU pins.

Most commonly pin-outs look like this (in some sort of order):

Pin # Symbol Function
1 R0 Red Data single (LSB)
2 GND Ground
3 R1 Red Data single
4 VSync Vertical Sync Signal
5 R2 Red Data single
6 HSync Horizontal Sync Signal
7 R3 Red Data single (MSB)
8 GND Ground
9 GND Ground
10 CK Clock Signal for sampling data
11 G0 Green Data Signal (LSB)
12 GND Ground
13 G1 Green Data Signal
14 TST Should be opened during use
15 GND Ground
16 TST Should be opened during use
17 G2 Green Data Signal
18 GND Ground
19 G3 Green Data Signal (MSB)
20 GND Ground
21 GND Ground
22 Vcc +5 Volt Power Supply
23 B0 Blue Data Signal (LSB)
24 Vcc +5 Volt Power Supply
25 B1 Blue Data Signal
26 TST Should be opened during use
27 GND Ground
28 ENAB Data Enable Signal
29 B2 Blue Data Signal
30 GND Ground
31 B3 Blue Data Signal (MSB)

Thanks for the response. That's interesting - apparently the monitor is a VGA TFT (the guy had it working off a databrick), but the data sheet Datalux faxed me did say "Dual Scan" in one corner - I suppose they sent me the wrong one. Assuming I can get this mess figured out - how do I match things like R1, R3, etc. to the P1, P2, etc. pinout on the Earthvision or the D1, D2 on the SIL154 I have? Again, thanks for the help.
