Input signal out of range but resolution settings are the one that message tells us to change it to

[Flexxlord]

I got this monitor to connect my child's Chromebook to the display using an USB C to HDMI hub and then an HDMI to HDMI cable (both support 4k). However, when I connect them the monitor displays a "signal input out of range" error and its telling me to change my resolution to 1920x1080 - 60Hz, but when I go to my display settings on the chromebook, it is at 1920x1080 - 60 Hz. If I choose a lower resolution, the monitor does display video from teh chromebook but its completely distorted and colorized. I tested the 1920x1080 - 60Hz settings on my phone using Samsung Dex and just plain mirroring and it worked fine (other than some occasional black screen flicker). How can I fix this?

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• What is the Monitor product number? Use this link to find it: http://support.hp.com/us-en/document/c03754824
• Have you tried factory default settings using monitor menu button? 

While you respond to that, let's try these steps: 

Adjust your screens: Chromebook 

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.

Hope this helps! Keep me posted for further assistance.
