Console starts but monitor is unresponsive: Troubleshooting and solutions

When we turn on the computer, we sometimes encounter a situation like this: the host starts up, but the monitor does not respond. This could be due to a number of reasons, including hardware issues, connectivity issues, or operating system misconfiguration. In this article, I will provide you with some common troubleshooting and solutions to help you solve this problem.

1. Check the hardware connection:
   First, make sure the monitor is properly connected to the host computer. Check that the monitor power cord is plugged in and make sure it is working properly. Then, check whether the monitor data cable (usually an HDMI, VGA or DVI cable) is firmly connected to the corresponding interface on the monitor and host computer.

2. Check the monitor input source:
   Some monitors have multiple input source options, such as HDMI, VGA, and DVI. Make sure you select the correct input source. You can change the input source using the monitor menu or buttons, or use the monitor remote control (if applicable).

3. Check your monitor settings:
   Sometimes, monitor settings may need to be adjusted manually. Try pressing the menu button on your monitor and navigating to the settings option. Make sure settings such as brightness, contrast, and input source are configured correctly.

4. Check the graphics card connection:
   Check whether the graphics card is correctly installed on the host and the power connection is normal. You can try reseating the graphics card to ensure a good connection. If you have multiple graphics card slots, you can try plugging the graphics card into a different slot.

5. Check the graphics card driver:
   The graphics card driver is an important part of allowing the graphics card to communicate properly with the operating system. Make sure you have the latest graphics card driver installed. You can find the driver for your graphics card model on the graphics card manufacturer's official website and follow the instructions to install it.

Here's a sample code for detecting whether a monitor is connected and displaying a message in Python:
