Windows 10: Can't unmute laptop when connected to HDMI

Not sure if this is a Windows 10 issue but I just discovered that I can't unmute my laptop (Dell Inspiron 15-7568) when connected to my LG TV via HDMI. I used to be able to, but not sure if it's a recent Windows update that is preventing me from doing so now. I've unplugged and plugged it back in a couple times. The picture works just fine, but audio does not.

Checked that it's set to my default audio device in the control panel and it is, and also shows that sound is playing. So that's not the issue.

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.

 

Connecting laptop running windows 10 to hdtv with hdmi

I'm not very tech savvy.

• I know how to run the HDMI cable between laptop and tv.
• I know how to set my tv to use correct HDMI port.

What I need to know is how I tell my laptop to recognize my tv and configure it to use my tv as a monitor.

Anyone that can tell me step by step how to do this in windows 10?

Thanks.

Thanks for all the help. Hooked up the HDMI cable, plugged tv back in, started laptop up, switched the tv to correct HDMI port and viola...there was my laptop start screen on my tv! Didn't have to do anything but make a few display
adjustments!

Thanks again, everyone.
