Oracle Linux does no longer install a graphical desktop interface (Gnome) by default and there is no reason to perform a "minimal".
The problem might be that your monitor or cable is defect or is not able to handle the default resolution and frequency.
What happens if you go into the boot menu and add the following to the kernel boot prompt:
boot: linux vga=791
I don't even see the boot prompt as the screen goes off before it is displayed.
Edit: I've just down more testing. If i press a key when the booting into linux line of text appears, I get the option to select from 2 OS's. The first one, 'Oracle Linux Server-uek (2.6.32-300.3.1.el6uek.x86_64)' gives me a black screen. The second one, Oracle Linux Server (2.6.32-220.el6.x86_64) gives me a red progress bar and the option to log in as normal.
I'm not sure what the difference between the two options is other than version as I am just following an installation walkthrough from our software providers and I am not familiar with Oracle Linux.

You can try to add vga=791 to the kernel boot parameter following the instructions on screen at the menu where you selected the kernel. Alternatively, log in from a remote session using ssh and check /var/log/messages and dmesg for possible clues. You can also setup Oracle public yum following the instructions at http://public-yum.oracle.com and type yum update as root to apply the latest patchsets. if I remember correctly there was a certain bug affecting video, but I cannot locate the reference right now.

We have seen similar behavior with HP gear and Solaris as well as Linux. Check your BIOS for any redirections to your ILO. Also, IF you are getting to the grub menu, try adding a tty or serial setting (sorry, it's really late here and i cannot think of the correct entry), but this will most likely be if redirection is set to the tty or serial port.
