Among many mediums to transfer audio and video data between electronic devices, HDMI is the latest and the most widely used interface. HDMI stands for High Definition Multimedia Interface and for proper communication between two hardware components, both receiver and sender devices must recognize the HDMI signal and is often called HDMI handshake. In case there is a miscommunication due to one reason or another, there will not be any output on the display or audio device. You can resolve the issue of “no HDMI signal” by following DIY steps at home or your office.
The first and the most common problem can be loose HDMI connections. So, check the HDMI ports at both the source and output section. If you think the ports have become loose, you should buy a new HDMI cable and some good quality cables come equipped with a self-locking mechanism. Check HDMI cables on Amazon.
By changing the port, I mean you should try to change the ports both physically and on-screen software. Sometimes, by mistake, we change the input source on the TV or monitor, so open the display settings on the monitor (there will be a touch button or a push button on the screen-frame itself). Now select the appropriate signal source.
In case you are using the TV as an output display and audio device, it’s time to review your selected input source. You can press the source button on the remote and see all the available options. As you can see in the image below, you can toggle between HDMI1 or HDMI2 and so on.
So, apart from changing port settings on the software menu, you should also try to change the port physically on the output device. As you can see if you are not getting signal in one HDMI port try to plug-in the cable in another port.
On a windows system press windows key +P to open the screen projections. Here, you can see various options that include PC-screen only, Duplicate, Extend, and the second screen only. Make sure the right option is selected depending on the number of screens, you are using.
Check Device Drivers
If you are not getting a display on the monitor of your desktop PC, you need to recheck the software drivers of the display card or on-board display chip. Open device manager, (windows key+R and type “devmgmt.msc”). Now select the display adapter and right click on it to update the drivers. If you have drivers-dump on your system you can give its path or can automatically update the latest display drivers from the internet.
Not all but most of the electronics devices provide the option to factory reset them This is handy in case something goes wrong and allows you to roll back to the original settings. You can open the menu on the monitor and look for factory reset settings. Sometimes, you do net get display on TV set after firmware or software update on DISH-TV receiver/set-top box. If that is the case, you can open your dish-TV settings and set it to factory-reset to regain the display.
Most of us use converter cables to convert the DVI signals to HDMI or vice-versa. See the examples of HDMI to DVI cables. Chances of in-compatibility of these cables are high when we try to connect an older output device to a new input device or vice-versa. The reason is that your new device might be updated to the latest firmware and proper handshake is not achieved between older and newer ports. Furthermore, you must note that DVI is capable of transmitting only video signals and for audio, you still need to use audio ports.
This process is an act of recovering the electronics device from the state of un-responsiveness by resetting all the configuration parameters. To power cycle the monitor you just need to disconnect the HDMI cables and turn off the power. Now, wait for few minutes before turning it on. This method can work like charm for you.
Fix HDMI Errors
Today you will have to use HDMI cable in one or another electronics device at home or at your office. The problems are bound to arise as the devices upgrades themselves automatically in this technologically advanced world. The quick fixes mentioned above will definitely help you get back the HDMI signal and if it does not work for you, you should consult the tech support of the concerned input or output device.
