Hi everyone - long time lurker, etc etc.
So, I work from home for a global company in an InfoSec role and I have three monitors all connected to a Zotac GeForce 1080ti blower (basically a reference clone). I need to find a way to consistently enforce the selection of a particular monitor at boot time (BIOS) and in Windows 10. I cannot for the life of me find a solution, because all of the typical forum posts are full of people with good intentions and zero clue giving the usual utterly useless advice for "going to your Nvida control panel".
Here's what I've got:
Asus P348Q 34" ultrawide - must be selected as the boot monitor, must be assigned monitor ID #1 in Windows. Connected via DisplayPort
Dell P2418D 23" - mounted in portrait mode to the left of the Asus ultrawide. Connected via DisplayPort.
Cheap Blaupunkt 40" 1080p TV on the wall above the desk (used for network/security monitoring dashboards). Connected via HDMI.
Now before you go and ask me why I care that my 34" ultrawide is marked as monitor #1 when I can still just say "This is my Main display" in my windows settings, let me explain. I join web conferences daily, using everything from Skype for Business, Teams, WebEx, Zoom, Bluejeans, GoToMeeting, and whatever else is the current flavour of the darned month. In most of these, I need to screen share. EACH of these applications displays what they think is "screen #1" for sharing differently. Some apps respect the Windows display numbering, whereas other apps use the Windows "This is my Main Display" setting to determine what screen #1 is. And each time I go to screenshare I'm constantly saying "oops, sorry, wrong screen" in my meetings.
So, please, somebody out there - tell me how the hell to fix this consistently. What ports on the card should I use? Are the card ports prioritised? Should I avoid using the HDMI port? And please - facts! Don't just pass on what you have heard because Internet forums are full of that and it is not helpful.
