Do not double post, please, it makes it very hard for us to follow what has been already answered. Thank you.

That seems like a video signal issue, for sure, so try another HDMI cable if you can, and/or see the RPI forums for what settings you need to have in config for your monitor setup.

Just in case that is a RPI3 and you are using the "composite" analog output, see what your monitor can accept, be it PAL or SECAM or NTSC.

Trouble with Linucnc RPi

Category: Installing LinuxCNC

I installed the image from the download page and installed it on a RPi 4B and have an issue I can't figure out. I can get in and the image works, but the login screen is at a resolution that the little monitor I have doesn't support and it is skewed. You can make it out and get past this, and then reset the display setting once to the desktop, but if the Pi goes to sleep, or on next boot, the login screen resets the resolution back to the one my monitor can't support. How can I set both the login screen and the main window resolution to a specified setting.

Here is what the login screen looks like:
