HDMI Port Not Working in Windows 10 [SOLVED]

Fix HDMI Port Not Working in Windows 10: HDMI is a standard audio and video cabling interface used to transmit uncompressed video data as well as compressed and uncompressed audio data (digital) from HDMI supported source devices to a compatible computer monitor, televisions, and video projectors.

Fix HDMI Port Not Working in Windows 10

Many computer users have reported problems regarding the HDMI port. Some common issues that users encountered most of the time are receiving no image, the sound coming out of the devices even when the cable is properly connected to the port, etc. Basically, the purpose of HDMI is to connect different components together easily through this generic HDMI connector where one cable is meant for both audio and video. Though, there is another additional HDMI function for implementing ‘copy protection’ (which is also termed as HDCP or HDCP 2.2 for 4K). This copy protection typically needs the HDMI connected components to be able to look for as well as communicate with each other. This feature of recognizing & then communicating is commonly termed as the HDMI handshake. In case the ‘handshake’ didn’t work well at any time, the HDCP encryption (embedded within the HDMI signal) becomes unrecognized by one, or more connected components. This often leads to when you cannot see anything on your TV screen.

  1. The issue I had was with a relatively new (last 5 years) computer connected to an old (2007) flat screen TV which has fixed (1280×1024) resolution, versus multisync monitor. Guess I should have checked into the specs before hooking it up, but I actually got it working a year before but reloaded windows and found when hooking up the TV I got no display. This was frustrating problem as it worked with other (newer?) TVs which happened to be multiscan, but not the one I wanted to use in my Mother’s house (fits a particular space in her home). What would happen is that I couldn’t see anything on this monitor at all (even uefi menu doesn’t appear, guess it is displayed in something other than 1280×1024) and had to temporarily use another multiscan monitor on the vga port to set up the resolution, even then had a bit of trouble getting setup for single hdmi monitor; when I removed the VGA display the hdmi display also would go blank.

    Guess there should be some dialog panel when setting up monitor asking whether you can see anything on hdmi port device. I know the TV is old, and new TVs aren’t expensive, but it works fine now, and I don’t like just throwing money at the problem (guess I have luxury of time and patience to fiddle with it). The single resolution is what threw me. Of course I’ll still need to plug in VGA monitor to access uefi menu once in a rare while (unless there’s a setting I don’t know about to change video resolution when in uefi) but that’s fine, since my Mother never messes with any of the setup, she just wants to use the computer as most people would with her TV display as a monitor.

  2. The troubleshoot options do not exist anymore.

    Don’t you love how Microsoft not only “update” your OS to make it slower and instal spyware, but they also remove useful options to fix the mess they created?

    Thank you Microsoft.

  3. W10 uodate KB4592449 caused no problem to my HP laptop, but my wife’s Lenovo lost connection to her other monitor. I had to:
    1) use Windows key+P to set the display to multiple
    2) Right click the desktop, select graphic properties, and the intel graphics program opens.
    3) Select Display, click Display (upper left corner of window in blue panel for a dropdown menu, and select multiple displays.
    4) Select detect. I get a message saying no other displays are detected. Click “OK” and the display “magically” appears on the both monitors.
    5) I can find no way to save this. Every time we start the Lenovo, we must go through the above procedure.
    Thanks MS.
