HDMI Output not working? cannot extend to 2nd display. (on Acer Nitro 5 AN515-52)
I just bought an Acer Nitro 5 AN515-52 i-5 8300h GTX 1050 about 3 months ago, but HDMI never works I'm not sure what is the problem.
I try it with 2 HDMI 2.0 and 2 television but nothing is working (all of them are work fine with another laptop).
when pressing fn+f5 or windows+P, Project option came out (Duplicate, Extend, 2nd screen) but when I click it nothing happened, On advance display setting only showing 1st Display nothing else, I tried Looking at 'Intel graphics command center' and only detected my main Display no other Display, Tried by looking to Nvidia and nothing....then tried it On-Device manager by Un-install and install newest Display adapter many time, both intel and Nvidia but still nothing. now I think my Laptop was a defect product cause I Tried everything, searching all over the internet and try all of them and nothing has solved my problem.
Now I don't know what to do, maybe anyone here can answer my problem? I really need this cause I got a presentation every week...
