def check_monitor_signal():

    print("Checking ASUS monitor signal...")

    time.sleep(2)  # Simulating a delay for the check
    # Simulating a random result (True/False) for monitor signal

    import random

    signal = random.choice([True, False])
    if signal:

        print("Monitor signal detected.")

    else:

        print("No signal detected. Possible causes:\n"

              "- Monitor not powered on\n"

              "- Incorrect input source\n"

              "- Loose cables\n"

              "- Faulty graphics card\n"

              "- Other hardware issues")

# Calling the function to check monitor signal check_monitor_signal()

This code creates a function `check_monitor_signal()` that simulates checking the signal of an ASUS monitor. It includes a simulated delay of 2 seconds to mimic the actual check. The function generates a random result (`True` or `False`) to represent whether the monitor has a signal or not.

Based on the result, it prints either “Monitor signal detected” or provides a list of possible causes for no signal, including common issues like the monitor not being powered on, incorrect input source, loose cables, faulty graphics card, or other hardware issues.
