  1. Connected a new monitor to my pc and now both my monitors say “No Signal”


    I bought a new monitor and I connected it to my pc it was fine and after a day it stopped working and now both of my monitors say “No Signal”.I already tried disconnecting and switching the cables, as well as trying hdmi and Displayport and it doesn’t seem to be fixing anything.I removed my RAM and it didn’t fix it.Don’t know what to do now since I can’t enter windows because it doesn’t detect none of my monitors.

    :)

  2. Monitor not receiving signal from pc after using hdmi passthrough

    Hi,

    Thank you for writing to Microsoft Community Forums.

    HDMI Pass-Through does not work with all devices. Before attempting to set up an HDMI Pass-Through connection, you should make sure the source of the signal such as a Blu-ray player or Set Top Box, supports HDMI Pass-Through.

    In order to get clarity on this issue and assist you with appropriate troubleshooting steps, please reply with the answers to the questions below.

    1. Did you try a different HDMI cable to connect your PC to the monitor?
    2. When you say "my pc will not display to my monitor", are you able to see any error message on it? For example: 'No signal'.

    Meanwhile, try the below suggestions and check if this helps.

    • If your monitor has an option in the Menu Button to switch the
      Input Source to HDMI Port, I would suggest you to try it.
    • Try completely disconnecting your Xbox from the computer and just connect your computer to the monitor and check if you are able to see the display on the monitor.
    • Make sure your display is plugged in and turned on.
    • Unplug the video cable from both your display and PC, and then reconnect them firmly. After you reconnect the video cable, try moving your mouse on your display.
    • Try connecting to different video outputs on your PC. Sometimes a change in driver can cause the video to be sent to a different display adapter or output.
    • If you have your own display adapter installed and connected to your display,
      try connecting your display to the built-in video on the motherboard.
    • Check for damaged HDMI cable, loose connections, or faulty adapters.

    Hope it helps.

    We're looking forward to your response.

    Monitor says NO SIGNAL

    You're probably going to have to get a hold of either another monitor or another pc. Take your monitor over to a friend's house and hook it up to his pc. If you still get no signal, it's the monitor. If the monitor works, something's wrong with the pc.

    Things to do once connected new G-Sync monitor

    I'm getting my G-Sync monitor today.

    I think I have to take the following steps:

    • Connect 1440p G-sync monitor with DP cable
    • Connect second 1080p 60Hz monitor by HDMI
    • Startup PC
    • Reinstall display driver
    • Restart PC (I always do that after display driver install)
    • Activate G-Sync in NV control panel (I believe also V-Sync is auto on after that?)
    • Set my 1440p monitor from 1080p to 1440p
    • Calibrate my 1440p monitor
    Also ingame, I should turn off V-Sync?
    Are there any problems running a second 60Hz 1080p monitor?

    Is there anything else I should do/know?
