Screen Extend on 2 laptops not working

Hi, I recently tried extending my current laptop screen to the 2nd laptop using "Project this PC" option on Windows 10.
-I watched several tutorials from YouTube but still didn't work.
-It seems the laptops discovery mode on the both Laptops was failing.
-I rebooted the laptops and toggled the settings in display property, pressing Windows + P to bring the extend Screen options and this is the step where both PCs were failing to get discovered.
-Both laptops are using Windows 10. Same Wifi internet.
-I also installed separate App from Asus called "GlideX" which is specifically designed to share/extend screens on Asus or any other laptop/ mobile device but that also failed.
-In project this PC at display setting there is option to screen share if "pc is plugged in" I unchecked that also but still not available.
After taking extensive steps now I am looking forward to get feedback from professionals?

 

Extending Screen to Laptop

Pressing MS KEY + P brings up PROJECT which shows display options PC screen only, Duplicate, Extend, Second screen only. After selecting Extent I then click on the “Connect to a wireless display”. Then I select my laptop that is listed.

That has worked well in the past, but the during a session a few days ago the connection dropped and I have not seen my laptop in the list since.

I have not found any steps to take that actually address this issue.

 

No Signal on the extended display

Need your help, google didn't help.
Short description:
No signal on the extended display
Laptop: Dell xps15 9570
OS: Windows 10
Display: Philips 245E
Details:

• connection - HDMI
  
• it was working before, but nothing has changed, after a few days of being turned off just stopped working
  
• display is detected by the laptop, I can see it in Display settings. But "no signal" on the actual display.
  
• Speccy link: http://speccy.piriform.com/results/80vYxevPHSAuYLWTKoLb5Kd
  

I am 100% sure that this is a software issue with Windows.

What have I tried:

• plugin another laptop to my display - it worked. The display is working fine with other laptops
  
• plugin another display to my laptop - it worked. I tried to connect my laptop to a TV using the same HDMI port - it worked
  
• switch HDMI cables - no result. HDMI cables seem to be fine
  
• reinstall display, and video adapter drivers - no result
  
• tried different modes ( extend, duplicate, only pc, only extended ) - the same situation in all modes, display is detected but "no signal"
  
• I have booted from a USB stick (Ubuntu) and the display worked without any issues
