How to change monitor 1 for monitor 2

Hmm. Thats really odd. I just tried it myself. Worked flawlessly. This must be something specific to docking stations. The OP mentioned a dock correct? And I saw others mentioning docks. I know it works on a regular desktop. I've done it on many different ones and various video cards. It's possible that it's something to do with how windows recognizes ports from the video card that is on board on the laptop versus how it sees the ports which are part of the docking station. Ultimately the graphics are derived off the on board video card from the laptop but I imagine there is something inconsistent with how the ports are recognized on the dock versus the laptop.

That is really strange. I've done this so many times with various versions of Windows and on multiple pieces of hardware over the years. But I cant remember if any specifically had a dock station involved.

I've tried this by using different HDMI and DVI ports.  Something with windows fully recognizes the driver of the monitor and doesn't allow it to switch the Monitor Identity Number.  So monitor 1 is always 1 and monitor 2 is always 2, regardless of which order and which plug i insert them into my video card. 

That's why this problem is so frustrating, and you would think would be seemingly easy to fix on microsoft's end(just allow us to change monitor numbers in software).

Now I have this problem, but did not have it before getting a new monitor.  Like most, I use the TV as an extended monitor and it stayed as monitor 2 and caused no trouble when I was using an older HP DVI input monitor.  The new HP monitor is wonderful, but only has VGA and HDMI and like others I only have one HDMI output from the computer. The HP monitor will not stay as monitor 1.  I uninstall the TV and get everything set with the HP as monitor 1 for the desk top.  When I plug in the HDMI TV, it automatically takes over the monitor 1 position.  That's fine until I turn off the TV.  The TV si going through a sound bar.  when I turn off the TV, the HDMI takes over  as main monitor and in can not use my computer. 

Very upsetting that this problem has been going on for so long and there is no solution in win 10.  Why won't the just let me select the main monitor and have that stay put.  Seems like a simple thing to fix.  ****?

I agree !!!

I have a Wacom Cintiq and I HAVE to have the Cintiq as PRIMARY MONITOR or it will NOT use the proper calibration for the pen display.  Before you give me a laundry list of **** that I have already done, please note: I have updated my drivers from WACOM to the latest; "Make this monitor my Main Display" is NOT the answer; turning off the computer and only plugging in the Cintiq through the startup DOES NOT WORK.

Prior to Windows 10 there was an option to change PRIMARY DISPLAYS... now it is gone again with this version!  FIX THIS NAOW!
