If you've checked the HP site for the latest drivers for your laptop model, you may have noticed that AMD drivers have been added. Finally, the laptop > HDMI > TV connection issues I have been having are 100% fixed.
What I did was - I uninstalled the previous drivers using DDU in safe mode. Then I downloaded and installed the drivers on the HP site, which can be found here. This is the direct download link: http://ftp.hp.com/pub/softpaq/sp71501-72000/sp71870.exe
The TV is recognized now and am able to extend my desktop.
