On servers I've set up recently, I'm getting Out Of Range messages during boot.  I get the Dell "BIOS splash screen" for a few seconds, and then it's Out Of Range until partway through Windows showing the spinning wheel.

This is causing problems, because I can't see menus to do boot-level configuration (System Setup, Lifecycle Control, etc.).  For example, I'm trying to figure out how to set up the iDRAC Network on R450 servers I'm getting in (on 2U, I can do it through the front bezel interface, but 1U servers don't have that).

What resolution is the system trying to display?  Is it changeable?  Or do I need to start looking for a differnt KVM model that can do the correct resolution?
