Hey, I have been trying for a couple days now to get this dual monitor setup working, I made sure both monitors work, which they do however when one is booted the other shows no signal, one is connected to vga and one is connected to dvi. When I connect the monitors through vga they power on however when I try to power them on through the dvi cable they get to the windows loading screen then shut off and it says no signal, I can power it on through safe mode and it works through dvi however I can’t do that when I have dual monitors, also I tried changing the resolution and that still didn’t work, can anybody help me

    Hello,Tommy Di Capri

    Welcome to Microsoft Community.

    It sounds like you've already done some troubleshooting, but there are still a few steps you can take to try and resolve the "no signal" issue on your DVI-connected monitor in a dual monitor setup. Here are some suggestions:

    • Check DVI cable and connections: Ensure that the DVI cable is securely connected to both the monitor and the graphics card on your computer. Sometimes loose connections can cause signal problems. Try unplugging and re-plugging the DVI cable to ensure a snug fit.
    • Update graphics drivers: Outdated or incompatible graphics drivers can cause display issues. Make sure you have the latest drivers installed for your graphics card. You can usually find the latest drivers on the manufacturer's website.
    • Boot in safe mode: Since you mentioned that the DVI-connected monitor works in safe mode, there may be a driver conflict causing the issue. Try booting into safe mode and uninstall any graphics drivers. Then, restart your computer and let Windows reinstall the drivers automatically.
    • Check BIOS settings: In some cases, BIOS settings may interfere with dual monitor setups. Enter your computer's BIOS (usually by pressing the Delete or F2 key during boot-up) and check if there are any settings related to multiple displays. Try resetting the BIOS settings to their defaults. If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.
    • Swap DVI ports: If your graphics card has multiple DVI ports, try connecting the DVI cable to a different port and see if the issue persists. This can help identify if there's a problem with a specific port.
    • Test with different DVI cable: The DVI cable might be faulty. Try using a different DVI cable to see if that resolves the issue.
    • Check resolution and refresh rate: Ensure that the resolution and refresh rate settings for the DVI-connected monitor are within its supported range. You can try setting them to the same values as the VGA-connected monitor and see if that helps.
    • Boot with only one monitor: Disconnect the VGA monitor temporarily and try booting the system with only the DVI-connected monitor. This can help identify if there's a conflict between the two displays during boot-up.
    • Check power-saving settings: Some power-saving settings might cause issues with dual monitor setups. Go to your computer's power settings and ensure that the display sleep or power-saving features are not interfering with the DVI monitor.
    • Try different DVI adapters: If you're using any DVI adapters (e.g., DVI to HDMI or DVI to DisplayPort), try using different ones to ensure they are not causing the problem.

    Hope it helps! If any update, welcome to share with us.
