I'm looking for advice on whether I can connect two extra monitors to my HP All-in-One computer. I have an HP tpc-q087-27 model and currently, I can only get two monitors to mirror each other instead of displaying separate content. I'd love to have a total of three monitors working simultaneously. Here are some specs to consider:
* Processor: 13th Gen Intel Core i7-13700T (16-core, up to 4.9 GHz)
* Memory: 16GB DDR4
* Storage: 1TB PCIe SSD
* Graphics: NVIDIA GeForce RTX 3050 with 4GB GDDR6
* Display: 27-inch FHD (1920 x 1080), IPS touchscreen
* Operating System: Windows 11 Home
* Ports: HDMI-in, HDMI-out, USB Type-C, USB Type-A
Any suggestions would be greatly appreciated!

Are you using the HDMI 1.4b output for your second monitor? That port is HDMI-in only, which won't work for connecting external monitors. You might want to look into an HDMI splitter or a different output option, like USB.
Since your All-in-One has just one HDMI output, you'll need to grab a USB to HDMI adapter for the third monitor. They're pretty affordable, around $15, and should do the trick! Just make sure to check compatibility with your model before you buy one.
To get your monitors working as separate displays, you need to adjust your display settings in Windows to extend the displays instead of mirroring them. Have you already checked that?
Just a heads up—if you plan on using an HDMI splitter, it typically just mirrors the signals, so you'll still struggle getting three separate displays that way. The USB adapter would definitely be the best route!
I did try extending the displays, but my third monitor isn't recognized at all. With only the one HDMI output, I'm stuck mirroring the two monitors.
