my monitor is an older model. I just got my hard drive fixed and reconnected it and my monitor upon hooking it up displays an error message that says “initial signal at a range, change settings to 14 40 by 900-600 HZ“. No matter what button I push I can’t fix this. Shutting the monitor on or off doesn’t help. Can anyone assist?

@Bea369, Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand you're seeing an error on your older HP monitor that says:
"Input signal out of range. Change settings to 1440 x 900 - 60Hz"
This message typically appears when the display settings on your computer are set to a resolution or refresh rate that your monitor cannot support. Here's how to fix it:
Step-by-Step Solution
Option 1: Boot into Safe Mode (Windows)
- Turn off your PC completely.
- Turn it back on and immediately press the F8 key repeatedly (before the Windows logo appears).
- From the Advanced Boot Options, select Safe Mode and press Enter.
- Once in Safe Mode:
- Right-click on the desktop and select Display settings.
- Scroll to Display resolution and set it to 1440 x 900.
- Click Advanced display settings > Display adapter properties > Monitor tab.
- Set the refresh rate to 60Hz.
- Restart your PC normally.
Option 2: Use a Different Monitor Temporarily
If Safe Mode doesn’t work or is inaccessible:
- Connect a different monitor that supports the current resolution.
- Boot into Windows and change the resolution to 1440 x 900 @ 60Hz.
- Shut down the PC and reconnect your original HP monitor.
Option 3: Use Low-Resolution Mode
- Restart your PC and press F8 repeatedly.
- Select Enable low-resolution video (640x480).
- Once logged in, change the resolution to 1440 x 900 @ 60Hz as described above.
I hope this helps.
Take care and have a good day.
