RE: Controlling DP and HDMI port settings on Precision 7720?
Good news and bad news. I got my 7720 yesterday and before it went belly up I checked the BIOS and there is a setting that assigns the discrete video card to all external ports. Couldn’t actually check it out as the machine stopped booting and couldn’t be resurrected after several hours on Tech Support. Replacement machine ordered, hopefully it will be a bit more reliable
