Bug Description

This does not work. I have been trying to make it work with the current distribution of psychopy (2023.2) and nothing makes sense been trying to fix it without success, and not being able to narrow it down.

My basic code:

`from psychopy import core, visual
from psychopy.iohub import launchHubServer

# Configure the eyetracker devicepip
iohub_config = {
    "eyetracker.hw.gazepoint.gp3.EyeTracker": {
        "name": "tracker",
        "enable": True,
        "save_events": True,
        "stream_events": True,
        "event_buffer_length": 1024,
        "monitor_event_types": ['BinocularEyeSampleEvent', 'FixationStartEvent', 'FixationEndEvent'],
        "calibration": {
            "target_duration": 1.25,
            "target_delay": 0.5
        },
        "model_name": "GP3",
        "manufacturer_name": "GazePoint"
    }
}

# Start the ioHub server with the configuration
io = launchHubServer(**iohub_config)
tracker = io.devices.tracker

# Setup a window for calibration
win = visual.Window(fullscr=True)

# Start the calibration process
tracker.runSetupProcedure(win)

# Main experiment code goes here

# Cleanup
win.close()
io.quit()
`

This is the error:

*** iohub warning: Display / Monitor unit type has not been set.

Expected Behaviour

connected to the eye-tracker and run calibration.

Steps to Reproduce
