screen mirroring

Hi Hatty,

There is a way for you to control the remote screen whenever you are trying to mirror it from one device to another. To provide you an appropriate solution, please provide us the following information:

• Which device are you using to mirror on your laptop?
• Are you using an app to mirror the device on your laptop?
• Are you able to use your mouse and keyboard on your laptop even if you are not playing a game while mirroring it from a device?

If you haven't tried to use your mouse outside a game while projecting to the PC, you may follow the steps below to allow your mouse and keyboard to control the remote screen:

• Open Action Center.
• Click the Connect button.
  
• Click the name of the device you're trying to project.
  
• Check the Allow input from a keyboard or mouse connected to this display
  option as necessary.

 

Project (mirror) Laptop to TV using Roku

Have a new 2 in 1 (HP) running Win 10. Have Roku 3 connected to my TV. I want to mirror my laptop screen to the TV so I can display slideshows (Photoshop, ProShow). I have mirror enabled on ROKU.

When I go into Intel WiDi, I can connect to ROKU and there is a list of folders on my laptop screen. If I select a folder with photos, and double click on a photo, it shows up on my TV. However, this is not mirroring, I cannot run a slideshow and project
it to the TV, only a single photo at a time and only if I double click on it.

Any help would be GREATLY appreciated.

 

Mirroring laptop screen to TV - works once only.

I found connecting to the TV hit and miss. I just did it and it took at least 6 tries. I found it sometimes makes a difference whether the laptop starts the connections first or the TV. All I can do is show how I do it and hope that helps.

BTW, my Samsung TV is ten years old and doesn't have Bluetooth. That is OK because I connect to my Samsung [BD]J6300 Blue-Ray player instead.

On the Blue-Ray player I open the Screen Mirroring app that comes with it.

On the laptop I open the notification area on the right side of the screen and...

• Turn on Bluetooth if it is not on
• Select Project
• On the bottom select Connect to a wireless display
• I then select [BD]J6300 from the list
• Within 30 seconds it will connect and display
