I have a Ryzen 7 2700x system without a graphics card. The CPU does not have integrated graphics, so can I use a USB to HDMI video adapter dongle as a graphics card?
every iteration of USB > HDMI\DP video adapters i've seen still have to have a graphical processing unit actually producing an image to output.I would argue it is possible, because a lot of USB to video output devices don't actually use an already existing GPU.

For one, there's DisplayLink https://www.tomshardware.com/reviews/usb-graphics-adapter,3006.htmlevery iteration of USB > HDMI\DP video adapters i've seen still have to have a graphical processing unit actually producing an image to output.
with no onboard graphics and no dedicated card, there would be nothing to output.
what you're describing sounds more like a type of external GPU setup, not just a cable adapter.
if you've seen articles describing & proving different, please post them here.
but, these are not just cable adapters like what the OP is questioning about.For one, there's DisplayLink https://www.tomshardware.com/reviews/usb-graphics-adapter,3006.html
For another, there's this device which uses DX WARP to do CPU rendering
If by adapter you mean some sort of signal converter like HDMI to DVI or DP to HDMI, then USB by itself doesn't support this because USB was not designed for video data streaming. At least in the context of an output from a GPU. Sure there's USB-C to some display output, but this is simply hijacking the pins on USB-C, there's no conversion going on. So every USB-A to some display output is going to contain some processing chip because the data coming across isn't going to be directly convertible to a display output.but, these are not just cable adapters like what the OP is questioning about.
these are external adapters that actually have a processing chip.
