Hello javajohn23,

Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I understand a horzontal line appeared on your display yesterday and you are requiring assistance in getting rid of it. I am recommending that you review and follow the steps set out in the HP Support document: Display Quality Issues. I think you want to focus your attention on the section Solid horizontal or vertical red, green, or blue line.

I hope I have answered your question to your satisfaction. Thank you for posting on the HP Forums. Have a great day!

We are on the right track.  The monitor in the emil showed how my monitor looks except the line is about 3 inches fromn the top on mine.  My PC is All-In-One.  There are no monitor buttons to push.

How do I reset the monitor on an All-In-One PC?

Hello again javajohn23,

Thank you for responding to my post and I am sorry I did not take into account the fact that this was a touchscreen. I would like you to try the HP Support document: HP TouchSmart PCs - Troubleshooting Touch Screen Issues in Windows 8, I believe the last 2 suggestions should resolve your issue.

Thank you again for your post on the HP Forums. Have a great day!

I'm sorry, the monitor is not a touchscreen.  When I ordered the PC I thought I had ordered the touchscreen but it turns out I didn't.  

I feel we are getting close to the solution.

Hello again javajohn23,

I would like you to try the following steps:

Step 1. Turn off the computer, and then remove the power cord

Step 2. With the power cord disconnected, press and hold the power button for five seconds

Step 3. Reconnect the power cord, and then turn on the computer

If the above steps do not resolve it try the next set up steps:

Step 1. Restart your computer

Step 2. Repeatedly press the F10 key about once every second for five seconds after turning the computer on

Step 3. Wait five seconds

Step 4. Press the F5 key. This restores the default settings of the BIOS

Step 5. Press the Enter key. This accepts the changes

Step 6. Press the F10 key. This opens the Save and Exit window

Step 7. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts

Step 8. Restart the computer.

Another thing I can think to try is review the HP Support document: Changing Display Settings, Background Image, Icons, and Screen Saver (Windows 7) to see if you can identify anything out of place.

We can also try to reload the Intel Graphics Driver for your computer as it will wipe out the settings when the new driver  is reinstalled.

Please re-post with the results of these steps. Thank you for posting on the HP Forums. Have a great day!

OK, the first thing, holding the power button down, did not work.  I set the defaults from the second thing and the line is still there.  I have a NVIDIA Graphics card GeForce 630M.  I cheked NVIDIA for updates and it said I have the latest driver.  It may have caused my problem but when I checked the Events log it said the last event was last year.

I have an option to uninstall the last driver but then I will have no monitor.

Any suggestions?

Hello again javajohn23,

We can reload the original driver that came with your computer using the HP Support document: Using Recovery Manager to Restore Software and Drivers (Windows 😎which will walk you through the restoration process. If this fails it would appear to be a physical issue and I think it would be best if you contacted HP technical support for repair options.

US support link to contact options for HP products purchased in the US.

Outside of US support link to contact options for HP products purchased outside the US.

I would like to thank you for posting on the HP Forums. Have a great day!

Thank you for your help.  I'll give it a try.

I went through all the hoops you gave me to do and tried them all.  I believe there was a driver installed that needs to be uninstalled or there is a hardware problem with my monitor.  I can't be without my PC for a long period so I will forego sending the PC to HP for repair.  I can live with one line across my screen for now.  If other lines show up I will rethink repair.

Thank you for your support.

John
