  1. monitor works with hdmi but not display port


    recently my monitor (dell u2412h) started glitching with horizontal lines flashing on the screen on and off in a continuos pattern (1 sec off 1 sec on). then one afternoon i restarted my pc and the displayport wasnt working anymore. tried the hdmi cable, and that one worked. when i use the display port cable the screen just says "entering sleep mode". i dont know if the issue is with my monitor or with my graphics card. i use an nvidia geforce 1050 ti. i have already tried plugging everything out and replugging everything back in. cutting out power from my monitor and pc separately. setting power management settings on the highest performance (the least power saving). any help is appreciated.

    Display port for HDMI not working

    I cannot get the second monitor to work. It seems there is no output signal from display port for HDMI. I'm wondering if there is some setting that need to be done? (The monitor (HP LA2306x) is working fine with another computer)

    Removed DVI/HDMI cable from computer and monitor

    Step 1: Check if the VGA monitor cable is defective.

    1. Turn off computer
    2. Connect the monitor VGA cable from the monitor to the VGA port on the computer
    3. Turn on computer, VGA monitor cable is good.

      Step 2: Tun off computer
    1. Connect HDMI Cable to HDMI port and TV
    2. Turn on computer and TV, there is no monitor black screen
    3. Click on the Windows logo, select the Settings icon , and then select

      System. Under Display there are two squares, labeled 1 and 2

  4. monitor works with hdmi but not display port

    HDMI Port Stopped Working

    I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

    I checked these:

    • Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
    • HDMI cable which I use works if another device is connected to the second monitor.
    • My computer detects my HDMI-to-VGA converter through HDMI port.

    My computer runs Windows 10 Home with latest updates installed.

    I suspect this is due to a driver error. How can I fix this problem?
