Since this is a trial run system, I want to upgrade later. So I decided to solder a vga port to the end of my video cable from the motherboard. This will allow me to use any lcd I choose now. It will also let me simply remove the laptop base and install an itx based system later.
I found a vga port w/ cable on the web. I am still looking for a wiring diagram of the A15-S127 video cable. But if I cannot find one to let me solder myself, I found a laptop repair shop that will do it for me at a reasonable price.
