Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

You can connect your Chromebook to a monitor or TV with an HDMI, DisplayPort, DVI, or VGA port.
Show your Chromebook screen on your monitor

• At the bottom right, select the time.
• Select Settings .
• In the "Device" section, select Displays.
• Select Mirror Built-in Display. Your screen will show on all connected monitors.

Tip: To view your Chromebook screen only on your monitor, press and hold Decrease brightness .

Adjust your screens

1. At the bottom right, select the time.
2. Select Settings .
3. In the "Device" section, select Displays.
4. To adjust your Chromebook screen, select Built-in Display. To adjust your monitor screen, select the name of the monitor.
   • Make items on your screen smaller or larger: In the "Display size" section, choose an option.
   • Rotate the screen: In the "Orientation" section, choose an option.
5. [Optional] Under your monitor tab, you can also:
   • Change screen sharpness: In the "Resolution" section, choose an option.

Tip: To quickly move windows or apps from one screen to another, on your keyboard, press Search  + Alt + m.

Hope this helps! Keep me posted for further assistance.
