Final answer:
The first step in installing a new monitor is to determine the type of cable that is compatible with your video card, using that knowledge to make the physical connection between the two devices.
Step-by-step explanation:
When installing a new monitor, the first thing you should do is determine what type of cable is compatible with your video card. Various monitors come with different types of connectors such as HDMI, DisplayPort, DVI, or VGA, and it is crucial to ensure that your video card has a corresponding output. If your monitor came with a cable, typically that's the one you should use. However, upgrading to a different type of cable that both your monitor and video card supports might offer better features such as higher resolutions or refresh rates.
Once you have identified the right cable, you can physically connect the monitor to your computer and power it on. After the hardware connection is established, you will then need to configure the display settings in your operating system to your desired resolution and refresh rate, which may involve accessing an 'advanced dialog screen.' However, finding the compatible cable and connecting the hardware are the first steps.
