I have asked a similar question before but we have upgraded some hardware. So I felt a new thread would be appropriate..
Recent desktop with DisplayPort built-in and two HDMI ports on a card.
The DisplayPort has a DisplayPort to HDMI adapter plugged into it and the main monitor is connected to the HDMI side of that adapter. .
One HDMI port (on the card) is connected to a HDMI to SDI adapter which goes to an ATEM and the other HDMI port is connected to a 4 way HDMI splitter that goes to four TV monitors on the walls.
The problem is at times the PC's main display screen shows up on the TV monitors on the walls or the ATEM as it's main display.
My guess is Windows is not finding its main monitor powered up on the DisplayPort and so it tries to find another monitor to use.
We need this to be more reliable as multiple people use this setup from week to week.
My assumption is if everything besides the desktop PC is powered up first, then Windows will always use the previous setup for display 1/2/3 when it's powered up? True?
Curious question, does Windows only look as far as one of the adapters to be operational or does it need to see the device beyond the adapter to make sure it can use it as a monitor? My guess is for the display port adapter it needs to see see the actual monitor powered on. But for the HDMI to SDI and 4 way HDMI splitter, seeing that device powered up is all the is needed. Does not to see a power up SDI device (HDMI to SDI) or a wall TV monitors (4 way HDMI splitter).
