This is a tangent of RPI Matrix, but as someone new to any Pi work this is the first time I’ve seen it. Back when I was solving errors and now that I am trying RGBMatrixEmulator things printed/echoed to the terminal do so in a spiral. So attempting to display a matrix in terminal looks awful. Even from my first lines that are simply drawing a 3 width border around the matrix, with straight forward graphics.DrawLine. The basic Simple\_Square doesn’t do this. Can anyone point me in the right direction for this? Distinctly different things acting the same and I don’t know why. My instinct is a /n but after a DrawLine doesn’t make sense. ---

from your description and no picture, this is not super clear. ---

ok, now you need to give very exact panel info, what panel is it, how many lines and columns? from your picture it may be a non standard panel (not 128x64 or 64x32) Then, what command line options did you try? But if I had to guess with the very limited information you provided, I’d say it’s a non standard panel that isn’t directly supported without you hacking the library. ---

Seriously? A terminal on a 1600x1000 monitor with Python Print()? If you are going to be like this you can just not answer. ---

> If you are going to be like this you can just not answer. I wish you luck finding help with such attitude. Like you have mentioned yourself, “this is a tangent of RPI Matrix”, since [GitHub - ty-porter/RGBMatrixEmulator: A desktop interface to emulate Raspberry Pi-powered LED matrices driven by rpi-rgb-led-matrix · GitHub](https://github.com/ty-porter/RGBMatrixEmulator) is a led panel emulator with [rpi-rgb-led-matrix](https://github.com/hzeller/rpi-rgb-led-matrix) python bindings emulation. While it’s more likely that you will find someone knowledgeable about RGBMatrixEmulator here than anywhere else, since the author of it doesn’t provide any community support link for it (like discord/discourse/forums), it’s NOT A GIVEN. This discoruse is mostly about [rpi-rgb-led-matrix](https://github.com/hzeller/rpi-rgb-led-matrix) support, predominantly hardware issues connecting panels with different ICs. ---

When he was blatantly not reading my post? When this same effect happens with the emulator setup, the terminal of a real matrix setup, and the SSH terminal of either. When it says “terminal prints” in the title. I am honestly confused by the ignoring what I’ve said. Which is that this happens with everything in my loop. Python Print() and drawLine. With the 000 picture and drawing in the terminal. But I will go somewhere else. The welcome post did not specify hardware only. ---

Sorry I am just now seeing this. I’m the author of this emulator and it’s not officially supported by the rpi-rgb-led-matrix team. If you have issues specifically with the emulator such as compatibility problems with real hardware, you can open an issue or discussion on GitHub.
