Hi, Ashish Saraf
Thank you for posting in Microsoft Community.
The mode of your Surface is switched automatically. It is in laptop mode with the Surface keyboard attached, and Windows 11 automatically switches to tablet mode when the keyboard is unplugged.
If you would like to use laptop mode when not using the Microsoft keyboard, this is currently not possible. We suggest you give us feedback on this great idea and we will take your comments into consideration:
- Go to Contact Us - Microsoft Support
- Choose how you would like to get support for your Surface device.
- Type in the problem you need help with.
- Look at any available solutions offered and select Contact Support.
Is your external display unrecognizable in the setup? or is it something else, sorry I don't understand it very well, please take a picture of your external screen's fault (mosaic for private information please) and add a description, thanks.
Looking forward to your reply.
