I have a computer display plugged into a DVI port, and TV plugged into the HDMI port. Whenever I turn the TV on it becomes monitor #1.
This is more of an annoyance than a problem, as I can make my computer display the "main display".
The annoyance is that it makes the Windows UI not make sense.
Here selecting PC screen only turns of my computer display, and selecting Second screen only turns of my TV.
Based on what I've heard from other people with the same problem, it seems like HDMI will always take over as #1. Is that so?
Is there any way to correct it?
