Both My Pc And TV Recognize HDMI But No Signal

Part 1: Why is My HDMI not Working on Windows 10?

There can be several factors behind the failure of your HDMI cable or HDMI port. If your HDMI is not working properly with your Windows 10 system, then it might be a hardware issue, graphic driver issue, device’s display configuration issue, or any other issue.

There are several ways in which an HDMI error can play out;

• HDMI not working at all on your HDMI device.
• The audio or video not working through your HDMI connection.
• The content playing through your HDMI isn’t playing properly.

How to Troubleshoot a Faulty HDMI Connection with a Laptop or Computer

If you’re attempting to use a PC or laptop as a source component, make sure your computer settings designate HDMI as the default output connection. If you can’t get an image from your laptop to appear on your TV screen, try these troubleshooting tips:

1. Boot up your computer with the HDMI cable connected to a TV that is already on.

2. Boot up your computer while the TV is off and then turn on the TV.

3. Boot up your computer and turn on TV before connecting the HDMI cable.

   If your TV has a Video Graphics Array (VGA) input you may have to use that instead of HDMI.

Solution 3: Updatethe chipset drivers and graphics drivers

The problem can be caused  by faulty chipset drivers and graphics drivers. Try to update the drivers and see if the problem resolves. If you don’t have the time, patience or computer skills to update drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1)Downloadand install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click theUpdate button next to a flagged driver (the chipset driver or graphics driver) to automatically download the correct version of this driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Why HDMI Problems Happen

HDMI is supposed to make it easy to connect all your devices with one HDMI cable for both audio and video. To do this, connected devices must be “licensed” to communicate with each other through a standard known as HDCP.

This ability to recognize and communicate media and devices is referred to as the "HDMI handshake." If the handshake doesn't work, that means the HDCP encryption embedded in the HDMI signal is not recognized by one or more of the connected devices. This usually results in you not being able to watch your movies or play your video games.

There are some things you can do to work around this issue. Here's how to troubleshoot problems with HDMI.

Solution 5: Disconnect all HDMI sources then reconnect them one at a time

If you have more than one HDMI source connected, this solution may work for you. If you have only one HDMI source connected, skip this solution.

Follow these steps:

1) Unplug all TV/monitor from the HDMI ports.

2) Unplug the power cable from the TV or monitor for about 10 minutes.

3) Plug the power cable back in the TV or monitor.

4) Plug one device to one HDMI port of your PC. 

5) Turn on the device. 

6) Repeat steps 4-5 for each device and HDMI port.

4. Change Multiple Display Operating Mode

If the above fixes didn’t work, you can manually change your PC’s ‘Multiple Displays Operating Mode’ using the Intel Graphics Control Panel. Follow the steps below to get it done.

Step 1: Right-click any blank space on your PC’s desktop page and select Graphics Properties from the context menu.

That will launch the Intel Graphics and Media Control Panel.

Step 2: Next, select Basic Mode and tap OK.

Step 3: Under the Display section, select Multiple Displays.

Step 4: Tap the Operating Mode drop-down button and check if the Intel Graphics Control Panel detects your HDMI monitor. If it does, you should see options to duplicate or extend your screen.

If your PC has a dedicated graphics card (NVIDIA or AMD), ensure that you have the latest version of the graphics card driver installed. Additionally, update or install the latest version of your graphics card control panel on your device from the Microsoft Store or the graphics card manufacturer’s website. For NVIDIA users, you can install (or update) the NVIDIA Control Panel from the Microsoft Store and use it to manually force-detect your HDMI monitor or TV.

For the AMD users, the AMD Radeon Settings can be used to force-detect an HDMI monitor on your PC. Before that, however, ensure your AMD graphics card driver is up-to-date.

Tip: Make sure you double check whether you’re using the correct HDMI cables that are compatible with the HDMI port versions on your computer and monitor/TV.

2. Switch Projection Options

The Windows 10 is designed to allow users to project visuals to a second monitor is diverse ways. With your PC connected to your HDMI TV/monitor, use the Windows key + P keyboard shortcut to launch the Windows ‘Project to a second screen’ menu.

Alternatively, you could also type project in the Windows Search box and select the ‘Project to a second screen’ option.

Before you proceed, here’s a brief rundown of the Windows 10 projection options.

1. PC screen only: Choosing this option will ignore the second monitor/TV and display output only on your computer’s screen.
2. Duplicate: This option will project (the same) content on your PC’s screen and the connected monitor(s).
3. Extend: With this option selected, a portion of the content is displayed on your computer while the remaining section is projected across other connected monitors.
4. Second screen only: This is pretty straightforward. Content will be displayed/projected on the connected monitor(s) only.

Note: The projection options mentioned above apply to all video connectors on your Windows desktop or laptop — HDMI, VGA, DVI, and Mini DisplayPort.

Now, if your computer isn’t detecting your HDMI TV/monitor, or perhaps it isn’t projecting correctly to your secondary monitor(s), check that the projection setting isn’t set to ‘PC screen only’ option. If your PC screen content still doesn’t project to your secondary monitor, proceed to the next fix.
