HP G42t-300 CTO Notebook PC

I have an HP w2207 monitor that use on two laptops, withing the cable depending on the machine.  Very frequently, I get an "input out of range" message with HP pc and the monitor will not work. Switching to the other machine, a Dell, the monitor works perfectly.  I have compared the desktop setting on both machines and they match. I have yet to figure why sometimes the monitor works on the HP machine and others it does not.  One more caveat, as soon as I plug the external monitor in I lose the PC screen. I do not believe this should happen, I should still have the laptop screen until I make a choice what to do with the external monitor.

 

Anyone have any thoughts on this issue.

Hi @KevinH20,

 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to assist you.

 

I see that you are facing an issue with your Laptop that does not detect the Monitor.

-Perform a power drain on your PC.

 

1) Unplug the power cord from the PC & wall.

2) Disconnect the power cable from the AC adapter if it is a detachable part and keep it aside.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the AC adapter, then connect it to the wall and to the charging port on your PC.

5) Power on the PC and check if it works now.

 

-Update the BIOS for your PC by clicking on the link.

 

Make sure you keep only the charger plugged in while updating the BIOS for your PC.

Click on the + sign next to BIOS and then download the file.

Open the file and follow the on-screen instructions to complete the update.

 

-Install all the pending updates for the Windows operating system following the below steps and let me know if that resolves the issue.

 

Go to Start > Settings > Update & Security > Windows Update and select Check for updates. If the upgrade is available for your device and you want to proceed, download and install it.

 

Please click “Accepted Solution” if you feel my post solved your issue, it will help others find the solution. Click the “Kudos/Thumbs Up" on the bottom right to say “Thanks” for helping!
