It's an FPGA, so there could be just about any logic on there. Most FPGAs need a bitstream loaded in order to work. I don't see a flash chip on there, so the FPGA probably needs to be loaded by a driver on the computer. In other words, you're definitely gonna need the software for it
The 57.2832 MHz crystal sounds a lot like what would be used to generate the dot clock for the monitor...
