Originally I was just using it to display the IP addresses after reboot on a smaller 0.96" 80x160. Then a screen shot... then zoom. I'm thinking more about some QR code with basic sysinfo.
can you array these off a single PI?
Imagine this:
An installation where there is an array of these screens - they are associated with whatever you want info on - they cycle btwn a screenshot of the item, some basic text (like IP/UPC/Barcode/QR to a fully detailed product/item page, uptime/health status...) etc...
And you can just have a PI running a bunch of these on a 42" rack, or on shelves of retail items etc....
If you're just starting out I can recommend looking at m5 which has nice little kits to get started. It's a bit pricier though. https://m5stack.com

I mainly use ESP8266, as it’s cheaper but it’s less powerful and doesn’t have 5v output, just 3.3v (or at least the ones I have were like this). I don’t have any real coding skill but between the Arduino IDE, ESPHome, MQTT and some mucking about, I got where I wanted to be.
The sensors are so inexpensive and there are so many (light, temperature, fire, smoke, moisture, humidity, distance, gasses, weight, open/close, current etc). It’s really impressive what is out there.
