When I use USB-C to connect an HP external monitor in the office it works but it does not work when I connect a Dell monitor (the same via USB-C)
I have updated the drivers but it doesn't work

Hi @Efecto26,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
It seems like you're encountering compatibility issues when using USB-C to connect your Dell monitor compared to your HP monitor. Here are some steps you can take to troubleshoot and potentially resolve the problem:
Check Compatibility:
- Ensure that your Dell monitor supports video input via USB-C. Not all monitors are equipped with the necessary hardware to receive video signals through USB-C. Review the specifications of your Dell monitor to confirm compatibility.
Update Monitor Firmware:
- Some monitors may require firmware updates to support USB-C video input properly. Check the Dell support website for firmware updates specific to your monitor model and follow the instructions to install them.
Verify Cable and Port:
- Make sure you're using a high-quality USB-C cable capable of transmitting video signals. Try using a different USB-C cable to rule out any cable issues.
- Check that the USB-C port on your laptop and the corresponding port on the Dell monitor are both functioning correctly.
Adjust Monitor Settings:
- On the Dell monitor, access the on-screen display (OSD) menu and navigate to the input/source settings.
- Ensure that the input/source is set to USB-C or DisplayPort (depending on the monitor model) to receive the video signal from your laptop.
Try Alternate Connections:
- If your Dell monitor supports multiple input connections (e.g., HDMI, DisplayPort), try connecting your laptop to the monitor using a different cable/connection method to see if video output is established.
Update Laptop Drivers:
- Ensure that your laptop's USB-C drivers are up to date. Visit the manufacturer's website (e.g., Dell) and download/install the latest USB-C drivers for your laptop model.
Check Display Settings:
- On your laptop, check the display settings to ensure that the external monitor is detected and configured correctly. Press Win + P (on Windows) or go to System Preferences > Displays (on macOS) to adjust display settings.
Test with Another Device:
- If possible, try connecting another USB-C compatible device (e.g., another laptop) to the Dell monitor using the same USB-C cable to determine if the issue is specific to your laptop or the monitor.
I hope this helps.
Take care and have a good day.
