Can I Connect A Second Screen To It?

Connection Options

HDMI-Out Port: Your Inspiron 5400 AIO should have an HDMI-out port. This is the most straightforward way to connect a second monitor. Simply use an HDMI cable to connect your external monitor to this port.

USB-C Port (If Available): If your Inspiron model has a USB-C port, it might support video output. In this case consider:

USB-C to HDMI adapter: A simple adapter to connect an HDMI-input monitor.

USB-C Hub/Dock: Offers multiple ports including HDMI, great for expanding your setup.

Troubleshooting

If the second monitor isn't detected automatically after connecting:

Check Cables and Ports: Ensure your connections are secure and try a different cable or port if available.

Manually Detect Display:

Right-click on your desktop and select "Display Settings."

Click on "Detect" to force Windows to scan for additional displays.

Update Graphics Drivers:

Go to Dell's website and find the latest drivers for your Inspiron 5400 AIO model.

Install them and restart the computer.

Check Display Settings:

In Display Settings, ensure that "Extend these displays" is selected rather than "Duplicate these displays" or "Show only on 1/2"

Additional Notes

Not all USB-C ports support video output. Check the product specifications of your specific model.

Some monitors may need an additional power cable - make sure you have that connected.
