Final answer:
To upgrade the computer's video output, a monitor is disconnected from the previous video card, a new HDMI video card is installed into the motherboard, and it's connected to the monitor via an HDMI cable. Then, the display resolution should be set to 1920x1080 for HD content.
Step-by-step explanation:
Installing a Video Card with HDMI Output
The process of upgrading a computer to improve its video output capabilities involves several clear steps. First, you need to disconnect the monitor from the onboard or current video card by removing the DB-15 connector. This is typically a VGA connector that is commonly used for video output. The VGA adapter is then removed from the motherboard of the computer, usually located in the back of the computer tower.
Next, you will need to install a new video card that provides an HDMI output. HDMI, which stands for High-Definition Multimedia Interface, delivers high-definition content, making it ideal for monitors and TVs that support the format. After selecting the proper video card with an HDMI port, install it into an available PCI Express slot on the motherboard. The video card may require additional power, so a 6-pin PCIe power connector from the power supply should be connected to the video card.
Once the video card is securely installed, you'll connect the computer to the monitor using an HDMI cable. After both ends of the HDMI cable are connected to the video card and the monitor, you can power up the computer. To finalize the setup, you need to configure the display resolution to 1920x1080 for full HD content, which is the standard resolution for high-definition displays. This resolution will ensure the content on your monitor is clear and crisp, even if the monitor supports a higher resolution.
