No display!

I've just purchased a touchscreen unit from ebay.

What I have done so far:
1. Purchased another 12v adaptor (1000mA) as the one supplied doesn't work.
2. Tried to run it on windows xp but there's no display.
3. Purchased a mac mini, installed the drivers, connect up the touchscreen but still no display.
4. I've tried to set the display settings at 640 x 480 60mhz, then attach the touchscreen, still no display.
5. The power led on the screen is on but i cant seem to get any vga inputs.

Any kind soul can help me out here?

ok, here's what i've done so far.

Plug in usb of touchscreen to mac mini

Vga out to my current viewsonic monitor

I can use my fingers and touch on the touchscreen and the cursor moves on my viwsonic monitor.

However, there is still no display when i connect up the vga to the touchscreen unit. Anyway it is a s video to vga cable output for the touchscrren.

Any idea what is wrong here?
