Already try the 3 methods and still not working.  Please i need some help connecting my laptop to HDMI.

This was a BIG disappointment also for me after upgrading to Windows 10.  Wasted a lot of time troubleshooting!  HDMI is used for business presentations - which now I cannot do.  One would think this would be a standard QA check from HP and Microsoft - such poor quality of effort and support! 

The solution my colleagues tell me, that is 100% guaranteed to solve the problem, get an Apple and forget this on going painful saga of software and hardware issues!  I think there is something to say about designing both the hardware and software.  I give HP and Microsoft till Sept 2 - then off to the Apple Store!

I have the same issue on my HP 2000 Laptop. Microsoft to fix this asap

Not all of us can afford to buy an Apple nor a new computer. They needed to get all the links out before the put a product online to the masses. Some of us are just don't have a lot of money to just go out and buy something new. We are just getting by.

Microsoft says this product was to make it more personal abl. But instead its a hot messy of confusion and it deleting Vidal  parts of our computers 

HDMI is not working due to your graphics card (NVIDIA or other) driver malfunction.

Re-install it manually designating the driver’s software folder.

Right click on the Start button > Device Manager > Display Adapters > Double click on Microsoft Basic Display Adapter > Properties > Update Driver Software > Browse my computer for driver software > C:\Windows\Drivers\EXE\Graphics Driver (NVIDIA)\

After rebooting, in case your screen gets black, reboot repeatedly to reach Troubleshoot and then > Advanced options > Startup Repair.

Not sure if Microsoft snuck in an update but my external monitor connected to my laptop via HDMI just quit working. It happened once before a few months ago but I don't remember what I did to fix it. This time I uninstalled the display adapter and rebooted and it started working again. (10/13/2017)

FINALLY !!!!

method 2 worked.

Thank you Sayan_Ghosh

i highly recommend that Microsoft realizes these issues before burning away at its users valuable time.

i wasted over 3 hours on troubleshooting this before finding this post (the only one advising these methods). i honestly dont have time for this type of manure, will be updating windows next time only after backing everything up and having a backup computer in case you decide to release something that smells like amateurs butt sweat.
