I had gotten the following from Intel support:
Regarding the Dell SP2309W monitor issue, we are checking the BIOS POST behavior on vBIOS mode. The GOP mode will use monitor native resolution per Microsoft Win 8 WHCK. The default is legacy mode/vBIOS mode, which control monitor through video BIOS. To change to GOP mode, you could disable “Legacy boot” in boot tab. But you had better change it when you have workable monitor with IGD. Most external graphic card not include GOP.
So from my understanding of the above, you can either use the new GOP mode which will use the monitor's native resolution or you can use "legacy mode/VBIOS mode".
I went into BIOS and disabled "Legacy Boot" as noted from support. This had two very interesting effects:
1) My monitor now worked during BIOS/Boot.
2) It could no longer find my SATA SSD to boot. It kept looking for a network to boot from. In BIOS Legacy boot displays my SATA SSD, but when I disable it, the UEFI can't detect my SATA to boot.
If the solution is to use GOP (disable legacy) which allows the monitor to work during boot, then I need to know how to get my SATA SSD detected so it can boot to it.
