10” Monitor calibration

Hey Trisha,

@Aiph5u

in its stock configuration, the Raspberry Pi 3 that is inside the Onefinity Controller is set to auto-detect the video mode. Of course it can achieve this only if the monitor is already powered up and ready, because it requests this information from the monitor. If the monitor is not ready, the Raspberry Pi boots into a very low default video resolution (as you already found out).

That is the exact reason why Onefinity tells you to first power on the monitor, and then, only after a few seconds, the Onefinity Controller.

@Aiph5u

However, in all situations where you don’t connect a different monitor every day, this auto-detection is not necessary. In that case it is possible to enter the resolution of your monitor in the Raspberry Pi and it will always boot to the correct resolution, even if the monitor is not on yet. This is desirable if you don’t always want to switch on the monitor first, but at the same time as the CNC controller, e.g. with the same power strip. How to do this is described here.

Also be sure that you connected all three(!) cables to the touch monitor.

How to connect the Touch Display is described in the Onefinity Manual on page 38 and 39.
