HP All-in-One Computer cannot detect HDMI Port in use

[IPOnUrWiFi]

I want to cry because I've had my All-in-One PC via HP for about 2 years and I've never tried to use the HDMI port it came with. Today my bf gave me his TV to use as an external monitor except it doesn't work!

I looked up many forums and directions from HP to random computer forums with questions on the same issue with no success.

First I: 

Tried turning on TV (Vizio) and plugging HDMI cable in, then plugging other end into computer (already on)-didn't work

Tried turning on TV and plugging HDMI cable in, shut computer off, plugged HDMI cable in and then turned PC on-didn't work

I used the windows key + C to select  Devices ->Project (Aware now that's for projector not TV) ->Second Screen-> Duplicate. I even followed those same steps but tried to add a device and it found my Android Phone across the room via WiFi but not the plugged in TV. 

I tried Right clicking my background and going into Personalize -> Display ->Change display settings-> Hit "Detect" and it says "Another Display Not Detected"...

I then tried to follow the suggestion made on the forum linked below that actually resolved the inquirer's issue who was having the same problem I have to no avail:

http://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/HDMI-in-port-switch-not-working/td-p/34...

I was getting frustrated. I then thought perhaps there's something wrong with the TV...HDMI cable... HDMI input/output (1 and/or 2) in TV...etc. To disprove this theory I tried using my TV that's 100% functional via HDMI with my gaming consoles and refollowed aforementioned steps with cord I know to be working. My PC still doesn't detect the connection!

I now know that for whatever reason my PC is just not even seeing the connection at all and I'm wondering if it's a driver/sofware/hardware issue?! Please help me all I want is to use a TV as an external monitor!

Hi!

Did you solve your problem? I'm having the same problem when I tried to connect an LG ultrawide monitor.

I did not solve my problem I ended up using a usb via a converter to connect the TV that way. Since the windows 10 update I haven't checked to see if the HDMI issue is resolved as it's a mainly known issue with Windows 8...but I will be getting around to checking if the HDMI port works soon. I don't think the port is broken as I had never used it...unless it came to me that way...but otherwise I do think it's something with a driver or even the version of Windows I had.

It's really sad, but check out the reply I got from them:

Wow lol that is literally so sad. That means you literally can't outsource to another monitor via the HDMI port so you'd have to do what I did and get an usb adapter that allows you to hook up a TV or computer monitor to one of your USB ports in your hp envy. They're not too expensive I got a good price on mine from newegg.com and mine actually isn't just a usb converter I got one that has multiple connects you can use. The good news is that especially if you upgraded to Windows 10 like I did once you connect and set up to extended settings whenever you disconnect or reconnect the usb the envy automatically detects the connection. Best of luck 😃
