Windows 10: How do I connect a laptop to a PC as a second monitor via HDMI?

Hi, I got a CyberPowerPC for the holidays, and would like to use my Dell Inspiron 7405 2n1 as a second monitor for it. I've tried connecting it with Wireless Display, but I don't like the delay between the two and the lag it has playing videos. I essentially want what Wireless Display does, but with a wired connection between them. I tried to get this to happen by connecting the laptop's HDMI port to the PC with an HDMI cable, and with a DisplayPort adapter, but the PC will not recognize the laptop as a viable monitor outside of Wireless Display. What can I do to get the PC to detect the lapto

Connecting a Second Monitor to Laptop

Hello,

I am trying to work from home with multiple monitors. I have one monitor connected via HDMI cable. I have the second monitor connected via a USB to HDMI cable, but the screen is not being detected by my Laptop.

I have no other output ports on my laptop besides the one HDMI port and the usb ports. Is there any way to get my laptop to detect the monitor connected via USB to HDMI cable? Or do I need a USB to HDMI adapter?

 

Second monitor not working with HDMI

Hi,

I have a AOC monitor hp Pavillion laptop and while trying to connect to the monitor using a HDMI cord, nothing is displayed. Comes up with a No Signal info. I have tried multiple cords : HDMI - HDMI, HDMI - DVI , HDMI - VGA, nothing works. The monitor is
not detected. I have another laptop on Windows 7 and and if I try to connect directly with VGA - VGA, it works, but does not work with HDMI from the same laptop. Basically, it does not work with HDMI at all.

I have updated the latest graphics card, both nVidia and Intel, but no progress.

If I use the same laptop and connect to my hd tv using the same cord it works, but does not work with my monitor. The monitor model is AOC e2450swh. It has support for HDMI. Even if I try to use a HDMI to VGA cord, still it does not display anything.

Any suggestions would be really helpful.

Thanks

 

Failure in switching audio from laptop to second monitor

Hello, CluelessCL

Welcome to Microsoft Community.



Thank you for describing the issue you're facing with switching audio output from your laptop to the second monitor via HDMI. It's essential to have a seamless experience when using external monitors. To assist you further, I'd like to gather some more specific details:

1-Can you confirm if the issue is specific to the second monitor's speakers, or does it also occur when using other audio devices, such as external speakers or headphones?

2-Have you tried different HDMI cables or tested the monitor's audio output with another device to ensure it's functioning as expected?

3-Are you using any third-party audio management software or apps that might be affecting the audio output switching behavior?

4-Have you recently made any changes to your laptop's audio settings or installed any updates that might have coincided with the time when this issue started?

Additionally, please provide the following details:

• The make and model of your laptop.
  
• The make and model of the second monitor you're using.
  

If possible, try the following steps and let me know the results:

1. Restart your laptop while keeping the HDMI connection to the second monitor intact and then check if you can switch audio output.
   
2. Disconnect and reconnect the HDMI cable while audio is playing on your laptop to see if this triggers the audio to switch to the monitor's speakers.
   

Once I have this information, I'll be able to provide you with more targeted troubleshooting steps to resolve the issue with audio output switching between your laptop and the second monitor.

Looking forward to your response so that I can assist you further.

Best regards,
