By the way, am I the only one who thinks it is insane that there is no built in trouble shooter for this? When I go to Display settings, shouldn't there be a little box saying "Is a second monitor not being detected? Click here to trouble shoot" or something to that effect? But I am left with absolutely no recourse. Come on, Microsoft.
You must have an APU (not sure what Intel calls it) and the onboard GPU. My laptop has an AMD A-10 APU, its a CPU and GPU on the one die/chip. It also has an onboard AMD GPU. AMD Radeon HD 7660G + 7670M, dual graphics. It can switch on the fly between the two depending on whether you need the extra power for gaming etc, or power saving using the APU. That goes back to my recommendation to install the Custom HP driver that should be able to handle the dual graphics. It sounds like yours switched back to the Intel APU, which doesn't have the ability to run dual displays.
What was the Custom HP driver? Where can I get it?I tried downloading an update via HP Support Assistant, but it is unclear whether it's installed already or not.I get a message saying:"Installation completeFailed installation: Intel Graphics Driver UMA-Skylake-Win10 (64-bit)-FXN"It still shows up as an update that can be downloaded and installed, but I've gotten the same message six times now.
Go to the support page for your make and model on the HP site. Then look through the list of drivers for a video driver. If you find one, download and install it manually.
Here, maybe? http://support.hp.com/vn-en/drivers/.../model/9062675
Looking at the list of drivers, I'm not sure that is going to help? I see AMD, Intel, and NVidia listed. Not what I was expecting? If it was a laptop there would be just the one driver. It's a desktop PC so they list the drivers for all the different options it might have shipped from the factory with. I'm just as confused as you are now? I don't know what you do now?
I think this link refers to the correct model but the drivers are the same and I would install the AMD graphics one dated yesterday (Jul 8). It might not hurt to install some of the other system drivers too as they are all recently updated.

Thanks guys, I really appreciate your help. Philc43, the page you linked to seems very promising, but right now the downloads do not work properly. Maybe too much traffic. Hopefully it will work better when I try again tomorrow.
The physical HDMI connection seems to have been somehow at fault, because after re-inserting the cables, the extended screen is now back. I was going to contact HP via their website, and they required a serial number, which I had to get off the bottom of my tower, and after turning it back on its keel and powering up, neither of my monitors lit up, which led me to pull out all the cables in the back, re-insert them and then boot up, at which point both monitors came back on.I swear I checked and double checked both HDMI cables (which are brand new high end cables), and they were firmly inserted, but it seems they are just very sensitive and prone to disruption at even minor upsets, at least in my experience when running the HDMI feed from laptop to TV.
