There are numerous causes for connecting the TV to the laptop via HDMI, sometimes stemming from the laptop, TV, or even the HDMI itself. If the root cause is not clearly identified, troubleshooting the specific error can be challenging.
How to fix issues when connecting your TV and laptop using HDMI
If you're facing issues connecting your laptop to the TV via HDMI and the TV doesn't recognize the laptop, it's likely because you haven't selected the correct display mode. You can access the Action Center using the shortcut Windows key + A and turn on Project .
Alternatively, press Windows key + P to open Project settings.
Here, you'll find 4 modes, and you should choose the second mode Duplicate .
- PC screen only: Displays only the laptop screen.
- Duplicate: Shows the same content on both the laptop and TV.
- Extend: Turns the TV into an extended display for the laptop, increasing resolution.
- Second screens only: Displays content only on the TV screen.
Another way to open it is by pressing FN + F8 keys (varies by laptop) to fix the issue of the TV not recognizing the laptop.
2. No HDMI signal on the TV
If you're facing connection issues between the TV and laptop via HDMI due to no signal on the TV, it might be because you haven't selected the correct HDMI source on the TV.
To resolve this, simply press the Source button on the TV remote.
On the TV screen, select the illuminated HDMI, and that's the quickest way to fix the HDMI no signal issue on your TV.
2.1. Check the TV's power button
Make sure the TV is powered on before connecting to the HDMI port. Try turning on the Menu or any mode on the TV to verify that your TV is turned on.
2.2. Check other inputs
To troubleshoot the TV not detecting HDMI connection, check whether the DVD player or game console is connected to the TV and if there are any malfunctions.
2.3. Check the HDMI cable
A faulty HDMI cable is also a scenario where images from the laptop cannot be transmitted to the TV. Ensure that the HDMI cable you're using is free from defects before purchasing.
3. Incorrect aspect ratio between laptop and TV
When successfully connecting the TV to the laptop, having the TV display the laptop's image incorrectly is entirely normal. To fix the HDMI connection issue caused by incorrect aspect ratios, we only need to manipulate the TV. If you're unsure how to adjust, you can refer to this:
Simply grab the TV remote, press the Menu button, and select Picture settings.
Here, you just need to adjust the screen ratio to 16:9 to resolve the HDMI connection issue due to resolution differences.
4. No sound recognition on the TV
Occasionally, when connecting your laptop via HDMI, you may experience a situation where the display appears, but the sound still comes from the laptop. To address this HDMI connection issue between the TV and laptop, we'll make adjustments on the computer.
Step 1: First, Right-click on the speaker icon, then choose Sounds.
Step 2: Here, select the Playback tab. You'll see that the sound is currently playing through the computer speakers. To change the audio output, choose the TV icon (in this case, Samsung TV), select Set as Default Device when clicking on the TV driver that appears => Choose Ok to confirm.
After setting the default mode to the TV, try playing music to see if the TV is now outputting sound.
