Second HDMI port not working

[Ohyaboiii]

Hello. I have an HP Pavilion TG01-1120 Gaming PC and I have been trying to set up a second monitor on my PC. I noticed that there was a second HDMI port near the top of the back, and that one doesn't seem to work. I tried buying a USB-C to HDMI adapter and plugged the USB-C into the port to the front of my PC, but still it didn't work. All my drivers are updated. Could someone help?

According to the product spec

https://support.hp.com/us-en/product/hp-pavilion-gaming-desktop-pc-tg01-1000i/32480786/model/2100019...

you  have a discrete graphics card, possibly GTX1650.  When that card is used, the onboard graphics are disabled.

A second monitor can only** be added using connectors on the back of the graphics card.  I was unable to find a picture that showed the back of the card.  Usually HDMI, DP and VGA connectors but sometimes DVI instead of DP.

What is on the back of the graphics card?  Take a picture if unsure what they are.

**  Some monitors can daisy chain a second monitor.  You will have to look up your monitor specs to see if it is capable of daisy chaining.  Normally the monitor will have a second display port to allow chaining a second or third.

Your machine could be one of the following machines

            https://support.hp.com/au-en/product/hp-pavilion-gaming-desktop-pc-tg01-0000i/29014479/product-info

Looks like it has a dedicated video card therefore other HDMI port is disable. The USB-C port at the front is a basic USB-C port as mentioned on its mother board

I need to know EXACTLY what is your machine to be able to help more.

I put in my serial number into the feature that tells me what my device is and it came up with th HP Pavilion TG01-1120 Gaming PCIntel Core i5 10th Gen 10400F 2.9GHz Processor; NVIDIA GeForce GTX 1650 4GB GDDR5; 8GB DDR4-2666 RAM; 256GB Solid State Drive

as @banhien mentioned, you can add a second monitor only at the dedicated graphics card.

If there are no additional connectors (vga, hdmi, etc) then an inexpensive wireless dongle could be attached to the second monitor and a connection made through WiFi.  It would lag terribly for games but otherwise will work fine.

Forgive me if this is a dumb question because i don't really know much about computers, but would getting an HDMI splitter such as

https://www.amazon.com/Splitter-LinkS-Amplifier-Source-Displays/dp/B0732MD43P/ref=sr_1_4?crid=1QX8IV...

and hooking it up to the HDMI slot that works and connecting a second monitor to that work?

Those are useful only when display identical screen such as teaching a language where everyone looks at the same screen in front of them and follows the same instructions.  Every display in the classroom would have the same screen information.

You cannot use that to extend your desktop

Oh. ok. I will just get a wireless dongle because im not planning on gaming on my second monitor. Thanks for your help!

Here is a gtx 1650 I found on ebay

It has one HDMI, one DVI, and two DisplayPoirts

Unless there is some custom build you can use all 4 of those to connect to four monitors.

I'll look into that. Thank you!
