Windows 10: monitor Display Identities.

    monitor Display Identities.

    Hi, I have a AMD R9 280 video card. I am running Windows 10. I have a new LG 27" lcd desktop monitor, and a 40" Panasonic plasma wall mounted, for watching movies. Outputs from my vid card are hdmi out to lg, displayport out to hdmi in on my surround sound receiver that is connected to the plasma. My problem is when I start my computer the Bios post screen shows properly on my lg monitor, than when windows loads everything goes to my plasma, unless it is turned on. I am trying to figure out how to run my desktop monitor without having to turn the plasma on, and leave it running? I have tried switching cables to no avail, and also tried windows display settings, and amd radeon settings. Let me know if their is a solution, or if I have to buy a new card? I have installed the latest graphics driver 15.301.1801.1001.160203a.299101e Thank You Paul Smith

    From my thoughts i think only Display port supports multiple monitors outputs on a video card.

    I don't think you understand the issue, this worked fine with a older 23" monitor, and doesn't work with the new 27" monitor my wife just bought me.

    In display settings click on the square 1 or 2 that represents your computer monitor. You can click the identify link to tell if the monitor is 1 or 2. With the correct square selected for the computer monitor and see if "Make this my primary display" is checked. It needs to be checked, then apply.

    My guess is, because your surround sound receiver is in between, windows thinks there is a monitor there all the time. Set the PC monitor as main, as suggested above. Then press the Windows logo key and the P key, then select PC only when your not using the Plasma. When you want dual screens press + P and select Extend. Or second screen only if you want just the plasma. I put shortcuts on my taskbar for PC Only and Extend so I can switch to 1 monitor when gaming and back to 3 when done gaming.

    I like your solution, but it might be tricky for my 7 year old, who shares my computer. So I found dvi out from my card to svga in on my PC monitor works. Thanks

    What ever works in the end and gives you the end result you want. lol, my wife would be totally lost on my 3 display desktop PC. She won't even go near it. She knows just enough to use her laptop for Facebook etc and that's it.
