This seems like a somewhat related place to ask this: Does anyone know where I can get a 3" round screen? I have a Star Wars clock from the 1970s that has a ton of empty space in the base. I want to put a small computer in it and replace the 3" clock face with a round screen, so it can show the time and maybe some fun Star Wars animations. But I just don't know how to find a 3" round screen without buying 1000 of them from China. How do I get just one 3" screen that I can attach to a Raspberry Pi or equivalent linux computer?

LilyGo has an ESP32 with an attached round TFT screen that's (I think) 2.8" diameter. You can buy single units on Amazon. One of the demo applications is a clock, but it shouldn't be difficult to load a bitmap.

  Looks like it's 2.1", but thanks for the tip!

Our (Pi compatible) HyperPixel Round is just shy of 3” if you count the thick, black border around the edges. Actual screen is 2.1” but diameter is 71.8mm.

  Ok wait, so when it says 2.1" that doesn't include the bezel? So the problem all along has been me reading it wrong? Thank you!

    Bear in mind I’m just reading the product page specs here but if you want me to measure mine I can dig it up!

I think Waveshare has some. I've been messing with their 1.28 in round ones and I like it. Just be aware that they will use SPI (think Arduino level) for the connection, not something video oriented like HDMI. Thus they can be used on a Raspberry Pi with a custom driver, but you won't be getting 60fps.

looks like lilygo just released a new 2.8" version -> https://www.cnx-software.com/2023/06/10/t-rgb-esp32-s3-board-gets-larger-2-8-inch-round-color-display/ https://www.cnx-software.com/2023/06/10/t-rgb-esp32-s3-board... with the touch layer it is bigger than 2.8" but I bet that can be removed. One comment there also links to aliexpress for a 2.8" hdmi screen but that one is more expensive
