From Windows 7 to 10, a new range of display and audio devices have emerged like HD TV, Smart TV, OLED TV, High Definition Audio, S/PDIF etc which still use the PC or laptop and HDMI wires.
For example, you have stored a movie, song, images on your laptop and want to get it displayed on a HD device. For the last 10 years, HDMI cables are the norm to interconnect both the devices. The computer which acts like the source has a HDMI port and the receiver (may be the display or audio device) has another port.
So, when we connect both these ports through HDMI cable we have a signal. Sometimes we have more than 1 graphic cards with HDMI slots on the PC and they can also be used in a similar fashion.
But as you know, any PC works on an OS like Win 7, 8.1 or 10 etc. So, in order to control the hardware, we use the computer as an interface using software to make them work properly.
So, this is like an introduction to the HDMI devices and how they work.
What are Windows HDMI Problems?
Just like any technology in this world, HDMI is also not without problems. As we mentioned earlier, this whole electronics mechanism consists of different parts and the problem can arise in one of them.
From forums and user responses, I have observed that the main HDMI problem when you connect a PC to a HD device is that either it is a display problem or no audio problem.
A Quick Solution to these kind of HDMI problems
Once you are sure that the hardware is working in such trouble cases, you have to look at the software part for the resolution.
Most computers and HD devices have more than one HDMI ports. First check whether you are interconnecting the right ports like HDMI3 TO HDMI3. This should be the first fix if you are not familiar with connecting these devices.
Next major problem comes in the form of no audio coming through the HDMI TV or any other HD device. This is very common problem that people face with Windows 10 and recent updates.
Since the causes for this kind of problem are many, I will give you one quick solution which generally fixes this kind of problem. The most important thing in this kind of case is that the HDMI output device like Sony HDMI output should be visible in Windows 10.
The following steps should be followed to check whether its seen or not.
- Open the Control Panel in your Windows.
- Then find the Sound item and double-click it.
- A pop-up window with different tabs opens.
- The first one is Playback.
- So if you have made all the HDMI connections correct and if PC and HD device are connected properly, your HDMI output device should be visible.
- Windows allows to play audio through only one device. So if you have multiple sound devices like laptop speakers, external speakers, HDMI TV speakers. etc, these all should be visible.
- Generally, the computer speakers are made default. You can see a green tick mark kind of thing.
- So if no audio is playing through the HDMI TV, then you should make that output device as the default one.
- But if your HDMI device is not visible at all, you should select any other playback device. Right-click it and there are two options
- Show Disconnected Devices
- Show Disabled Devices.
- If the High Definition Audio is visible there, then you have to troubleshoot them to appear normal. Then make them default.
This is a fast solution to many of the HDMI audio problems in Windows.
Another common jerk is that sound is playing but no display on the HDMI output device.
To fix this kind of problem soon, you may first check you have connected your TV cables and ports properly or not. Once you power on both the input and output devices, there is a phenomenon called as “handshake”.
This is like a protocol between the two devices. There is an understanding between the PC and HD display output, that everything is perfect and we are ready to go.
But sometimes this process doesn’t take place properly as it is a combination of electronic signals and software. For that to quickly fix it is to unplug your HDMI output device and laptop from power source. Keep the HDMI cables connecting them as it is.
Now plug the HD TV and laptop back to power plugs and switch it on. The “handshake” process may reset and problem can be resolved immediately.
Update Drivers using DriverUpdater Tool or from Manufacturer Sites
The last and easy solution to your Windows HDMI problems is updating the sound, graphic and video drivers. As it is common these days to have multiple graphic cards of different brands and Microsoft supplies some generic ones, you should first try to uninstall and re-install them. Then update the company drivers like AMD, Sony, Samsung, DELL etc. from their official site.
This can resolve the problems for Windows 10 and new versions, as they are new. You can also uninstall the Microsoft generic driver, that sometimes comes for Intel HDMI devices and install from the manufacturer site.
If that doesn’t work, you can try the reverse. That is try to use a generic driver available within the OS like 7, 8.1 or 10.
I hope these solutions are like a quick fix to your HDMI problems between computer and HDMI output device, but there are other causes which need different fixes. I hope this guide helps you to basic to medium level in solving your problems.
