Windows 10: Laptop cannot detect HDMI connection

Hello,I'm at my wits end here. I often connect my laptop to a TV or another monitor with an HDMI cable. I use an HDMI to USB-C connector. This has worked fine since I got this laptop last June.My device details: Lenovo Yoga 9i, Windows 11.A few days ago, however, the laptop would no longer detect a connected monitor or TV.This is not an issue with the TV or monitor or the cable. I have tested all of them using a different device, different cables, and even a different HDMI to USB-C connector, etc. They all connect just fine. The ONLY issue is when this laptop attempts to connect to any other d

Laptop not recognizing TV through HDMI connection

Hello everyone!

First I do apologize if this is not the correct section for this thread.

I've had issues connecting my laptop to TV for the past day. Connection is done through an HDMI cable. Connection was good up until it randomly turned off itself while playing a game. There have been no hardware or software changes whatsoever that would affect it.

TV is SAMSUNG, Model: UE32J4000AW. Laptop info is available in My PC Specs. (laptop is brand new, week or two old)

Here's what I've tried so far:

• 3 different HDMI cables
• switching between ports on TV
• tried all projection options on Laptop
• Disable / Enable both Intel and Nvidia drivers
• Rollback Intel GPU driver and installed it back to latest version
• Re-installed Nvidia driver
• Restarted PC and TV
• Scan for hardware changes through Device Manager
• Checked Intel and Nvidia control panels - there were no available options
• Apparently both HDMI ports on the TV work as I tried them with a tv box.

I think that's all I've tried so far, will add anything else if missed. Open to suggestions.

 

My TV is not detected when I connect to my laptop through Thunderbolt/HDMI cable

I have a laptop with Thunderbolt(Mini Display Port) and ofcourse TV has HDMI port. Si I bought a Thunderbolt to HDMI cable and connected the devices but TV is just not showing up when I press Detect.

Now, this laptop is not having any issues when I connect it with my external monitor, its just the TV which is not being detected.

• My laptop is a Lenovo T440s Windows 10
  
• TV is Samsung LCD 1080p
  
• Now, my laptop connects to other external monitor fine
  
• While TV also works fine with other devices like Roku very fine.
  
• its just the combination of laptop and TV is something that is not working at all.
  
• Here is the Thunderbolt that I am using: http://www.amazon.com/Cable-Matters-DisplayPort-Thunderbolt-Compatible/dp/B00APLJY4C?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
  

All I see is No Signal when I turn on the TV and choose the port from laptop

Any suggestions?

 

No display detected HDMI

Hi,

I am trying to connect my projector to my HP laptop with a HDMI cable but windows 10 will not detect the display.

I have tried the following:

Checking the cable on another device - works fine.

Updating device drivers for my graphics card (Radeon R5).

Uninstalling and reinstalling device drivers for graphics card.

Updating BIOS.

The strange thing is that connecting and reconnecting the HDMI cable enables the connection, as there is a pause and the projector appears in the device list of my graphics card but is not detected by Windows 10.

Both devices work fine when connected through the VGA port.

I have used the HDMI port before so this is also not the issue.

I can't help but think this is an update required for Windows 10 which may not even be functional yet?

Thanks.
