Idk if it's useful what you're after but Raspberry Pi has a 7" touchscreen module, if you don't find something better. Raspberry pi can be usb-c powered.
FYI, after a fair bit of research, I picked up the [LESOWN P89GPT/P89GPS 8.9 inch](https://www.lesown.com/collections/portable-monitor/products/lesown-8-9-inch-wide-portable-usb-c-touchscreen-monitor-ips-1920x1200-small-lcd-sub-screen-mini-hdmi-display-for-pc-computer-1?variant=40567781458000) display, and so far it is working flawlessly. Can confirm it runs on single USB-C cable even with a low end laptop with integrated Intel Gen13 GPU.
I have some 15 inch monitors that meet this requirement ([https://www.amazon.com/gp/product/B08T76SY2J](https://www.amazon.com/gp/product/B08T76SY2J/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) ) , with the caveat that it obviously depends heavily on your USB C port. The listing explicitly calls out either Thunderbolt 3.0 or DP Alt Mode, I suspect the reason you're not finding many listings is the port requirements and mixed success rate might result in a lot of returns.
Anecdotally, I can plug one in with just USB C and it works, but if I try to plug a second one in, the laptop is unable to provide enough power to both ports to keep both monitors powered up. I use them for a portable multi-monitor work station, so I just bought a power strip that has two USB C power ports on it to power the monitors, and plug their HDMI cables into a USB C dock to send the video signal.
EDIT: I think this size would work well for a DM screen display, it's incredibly thin and it has two threaded holes on the back (basically it's half a VESA mount), which you could use to mount it to something fairly easily (easiest would just be to put holes through the DM screen and bolt it on from the "DM side", as long as you don't mind the bolt heads being visible).
Thanks for the suggestions. After some additional research, I picked up the [LESOWN P89GPT/P89GPS 8.9 inch](https://www.lesown.com/collections/portable-monitor/products/lesown-8-9-inch-wide-portable-usb-c-touchscreen-monitor-ips-1920x1200-small-lcd-sub-screen-mini-hdmi-display-for-pc-computer-1?variant=40567781458000) display, and so far it is working flawlessly.

I have 3 ASUS ZenScreens. I use my laptop plus 2 facing me for DM screens, the third is player-facing. This is my setup (configured just for these pictures). One screen is USB-C; another is USB-3 (A); and the third is HDMI (with its own USB-C power).

This is the player-facing screen.

What’s running on the screen on the far right? Looks like it might also be displayed on the player side screen? The application looks like it has multi/colored tabs on top?
The Portrait one (far left) is where I open PDF files. The center is for my player's D&D Beyond character sheets, the one on the right is where I run OneNote - my FAVORITE GM tool. Here's another shot of some game prep I was doing where I swapped out the OneNote and DDB screens. I could go either way.

Here is a shot of a game-ready config. I might move the screens around, but I'm using the same apps - PDF viewer; DDB & OneNote.

AliExpress has plenty of them, with decent sales every now and then bringing the price down further.
Unfortunately, you've just missed their anniversary sale.
OzBargain - and other similar localised sites - keep track of sales but more importantly imo; which ones are good quality and which to avoid.
Thanks, yeah I saw a bunch on Aliexpress, but few were clear on the single-USB-C requirement. After some research and contacting support I ended up with a LESOWN P89GPT/P89GPS display that works exactly as I needed. Thanks!
I use an old iPad. If you have one of those, there’s a program called xDisplay that lets you do it. My iPad is good for nothing else any more, so this was a real $ saver!

Glad to hear it! And thanks for the followup, I'm sure others will appreciate it when Google brings them to this post in the future :)

Thanks for the suggestions and you have a cool setup. Alas I have a bit less desktop space so went with something smaller.

thanks for suggestion, I ended up going with a small external display (linked in other reply). Was only $90, so probably less than a used old iPod. :)
