Yes @yordan, it's a desktop not a laptop and I was using a monitor with it. 

After posting here I searched on Google and found this https://silicophilic.com/no-signal-for-your-windows-10-hdmi-to-tv/ article. They suggested some solutions. But I am a little confused, should I apply them to solve the issue?

Hello Friends, I recently purchased a brand new Acer Predator XB271HU 32 Inch WQHD monitor for upgrading my gaming experience. I'd like to use this as an extended monitor setup for my Windows 10 PC. I connected it with an HDMI cable, but not able to use it, as it is showing a 'No Signal HDMI' error on the monitor. Does anyone have any idea why this is happening? Kindly help me to solve my issue. Any kind of help would be greatly appreciated.
