Intel(R) HD Graphics "Not Working properly"

It's difficult to say without knowing what OS you're running, but this is basically a latter-day netbook --- it's not designed to do what you're trying to do with it.

The CPU was originally designed for "one laptop per child" and schoolwork -- it's not a fully capable Windows notebook CPU.

Bottom line:  you may be able to restore the video function with a reinstall (forget Windows 10 on these though), but if you really need a camera management notebook, you need something more capable than a netbook.

Isn't the OS Windows 10?

I don't think you can call it a netbook.  It's a 20" pc.

If you're really running Windows 10 on that CPU (it's a Bay Trail CPU, which started its existence as the Intel Atom, aka the basis of netbooks), that alone will be a struggle in 4G RAM.

You haven't specified the system model number, but that CPU dates from early 2014, so it's using pretty old CPU tech -- if it's anywhere near current it's essentially the 202x version of a Netbook, with similar capabilities.

Windows 10 runs poorly with an i3 CPU, 4G and a spinning hard drive -- I can't even begin to imagine trying to run it with a netbook-class processor.

These were designed to sell for about $300 and built to that price.

You can try uninstalling all the video drivers, rebooting and then reinstalling them  -- or just do a complete reinstall of Windows.

Dell Inspiron 20 Model 3043.  Sigh, I guess I got scammed by Dell.  I bought it new in 2015.

But I'd still like to know what I can do about the graphics card issue.

I actually bought the thing because of its configuration: large screen and hardware in/behind the screen, and then mounted it on the wall.  I figured that, running only one program besides Windows, since it came with Win 10, it would be able to handle that.  I like the size and setup of it.  Is there a piece of hardware (different graphics card, maybe? More RAM?) That I could change to make it work better?

No, there's no way to upgrade the GPU.  It's part of the CPU and soldered onto the system board;  there's no provision for adding a GPU to the system.

If it's running a conventional hard drive, the single best upgrade (assuming you can get the GPU driver issue solved first) would be to replace that with a solid state drive.  

There is only one memory socket, and while you can replace the 4G with an 8G module, that's unlikely to do much for system performance.

Can't just plug in a better cpu, I guess.  Don't see any compatible on the internet.  Too bad; it fit well, on the wall.  

Thank you for the information!

Here are two 20" "all-in-one" options available locally on Craigslist.  Might one of them better meet my need?  I don't need mouse or keyboard.
