No video with WinPE 4 on EFI boot

Has anyone else done any work with PXE boot to WinPE 4 on UEFI? I am using a 64bit WinPE of course.

Using the boot menu, I can choose IP4 option (and a cool thing is if booting to that fails, you get kicked back to the menu instead of the board trying to boot to the next device)

These UEFI PXE ROMs change things where instead of displaying F12 as an option, it says press Enter. This "F12" screen is the first screen showing this different video mode.

And here you can see what happens after I press Enter.

After the loading, when you'd expect the PE logo to appear with the loading animation, or even later on when the wallpaper should show up and then the command prompt (startnet.cmd) you never see it. Either you see this last screen but with just a black box inside, OR you just have a totally black screen.
NOTE: UEFI boot from CD/DVD is not an issue. Also a previous product, a CZC tablet, that also could do UEFI PXE boot, did not display this behaviour.
EDIT: I wanted to note that the successful CZC tablet PXE boot was done to Server 2012 RC, not RTM.

The recommendation would always be to rebuild the server cleanly, rebuild the PE image from a known-good ADK installed source, and try again. If the problem still persists after doing everything right, then the recommendation is always to engage Microsoft to see what is happening at that point.
Again, after talking to Trip this is an RTM install of Server 2012 with an image that seems to work on other UEFI systems from this server without issue, but I figured I'd throw this blurb out there just in case someone comes across this in the future.
