  1. Computer doesn't detect/use more than two screens.


    Hello,


    I recently upgraded the hardware in my computer, replacing the motherboard, CPU, PSU and case and ever since then there has been this odd issue where the computer will only accept two screen inputs at once and I cannot change which ones without a restart.


    I have two monitors, a TV and a VR headset. If I was to start the computer with the TV and the two monitors on, it will only use the TV and one of the monitors it seems to choose which monitor to use randomly. The only way to get that second monitor to be detected is to turn off my TV and restart the computer. Turning off the TV and turning on the second monitor while the computer is still on doesn't work, only a restart will reset which inputs are detected/used.


    This is the same for my VR headset, If I want to use it I have to turn off one of my monitors, restart the computer and blindly log in as the display does not come up on the monitor until logged in, I assume it is trying to use the VR headset like a normal monitor.


    The computer with all four devices plugged in does not physically detect any more then two displays. I have checked both Display settings and Device Manager. If I was to start the computer with only the two monitors on using the first and second display ports in the graphics card and then take one of the working monitors and plug it into the third Display port, that monitor would no longer be detected. It seems to only enable two


    The two monitors are plugged in via Display Port, the TV and VR headset use HDMI.


    The Hardware:

    Intel i9 9900KF

    Z390 Aorus Elite Motherboard

    Aorus RTX 2070 - NVIDIA Driver Ver. 456.38

    Thermaltake GX1 700W PSU


    Any help would be appreciated.

    :)

    Windows doesn`t start. Authomatic repair doesn`t work.

    Thanks again!!

    I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

    I`ll do it and I`ll be updating this thread when I have the report.

    I ran SeaTools. These are the results:

    Does it mean my HDD is useless?

    Computer doesn't detect/use more than two screens.

    Lumia 620 doesn`t connect to computer via usb cable

    Hi yall and thanks for the replies!



    Unfortunately, the were of no help.



    The phone isn`t listed in device manager, the list of devices doesn`t change if I have my phone connected to my computer(s). There are no mystery devices, no yellow triangle -markings or anything even remotely pointing to the direction the phone being connected.

    It could be that my phone has a broken usb port, but it makes me wonder that it still charges the battery when connected to a computer.



    This is not a big problem for me, that I must admit, but still, it kinda bugs me that the phone doesn`t work the way it`s supposed to work,



    Anyways, if somebody comes up with something that might help, I am most grateful.



    Have a great weekend yall!

    edit: Also, I have my laptop almost always connected to charger. Tried without charger just for the heck of it, didn`t help.
