Thank you for the feedback,
I have a DRAC4/P card that connects to PCI slot and and interface cable connects the DRAC4/P card and RAC connecter on the motherboard.
I have connected my monitors's cable to my DRAC4/P card display connector. I have figured with experiment that If my DRAC4/P card is installed on the motherboard then that automatically disables the on-board video output on the motherboard.
Which only gives me a hint that if i spend some money and buy a graphic card (that is supported by win server 2012) I may be able to get some good graphics, problem is i do not know if that will ever work or what graphic card to buy ?
BTW I have updated my BIOS to A06, which is Latest version available on dell's download page for PE6850.
Any idea which one should i go for ?
Thanks, Sheeraz
