I'm just checking the connections for your motherboard display, but you keep mentioning you don't have integrated graphics. Are there any USB, video, or audio ports missing? If you link the display to your board, you might be able to power it up and see if it works.
Is there a distinct beeping sound when powering up your device? A single prolonged tone followed by two brief beeps usually signals a malfunctioning graphics card.
