Welcome to HP Forums, 

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand there's a Floating message box that reads "Input Not Support", 

Don't worry as I'll be glad to help you, although, to provide an accurate solution, I'll need a few more details to dissect your concern: 

Are you using the monitor with a VGA or an HDMI cable, have you tried using different cables?

When do you get this message, while attempting to play a high-resolution game/video? or when you turn on your PC?

Have you attempted a system restore to an earlier time it had been working fine?

While I await your response to my question, here's a few things you can do:

Start the computer in safe mode > try to change the resolution.
Then update the graphics driver from the Official HP website: Click here

Let me know how that pans out, 

Feel free to post your query for any other assistance as well,

It's been a pleasure interacting with you and I hope you have a good day ahead.

Hello, Riddle_Decipher.

   First of all let me thank you for your assistance. The reason I was far from my desktop I didn't do your recommendations before.

  I entered "Safe mode" but no chage. The same problem of the floating message box "Input Not Support". Besides I tried to update the drivers via hp.co with no success. I am using the monitor with VGA cable. The floating message appears when I turn on my PC. I had the same problem before the system restore. I restore the system some of one or two months ago. I started my PC in safe mode and changed my resolution in normal mode. 

Waiting for your response as soon as possible.

Best regards, DevelopUS.

P.S. My desktops OS is Windows 10 Home Edition 64 bit. HP Pavilion Elite HPE-110ru Desktop PC

Hello, @DevelopUS

Thanks for the update!

I see that you were interacting with @Riddle_Decipher. He is out of office today, but I will be glad to help 🙂

First thing to check is if the monitor cable has been disturbed. Try unplugging and replugging the VGA cable on both the ends. Next, try powering down (everything) and leave it for a few minutes, power back-up and see if it fixes itself.

If this fails, try an automatic repair. Here are the steps:
 

1. Turn off the computer.

2. Disconnect all connected devices and cables such as Personal Media Drives, USB drives, printers, and faxes. Remove media from internal drives, and remove any recently added internal hardware.

   Do not disconnect the monitor, keyboard, mouse, or power cord.

3. Turn on the computer and repeatedly press the F11 key about once every second until the Choose and option screen is displayed, and then continue.

4. On the Choose an Option screen, click Troubleshoot.

5. Try Automatic Repair and also try reset and refresh options to check if that helps.

Please let me know if this resolves the issue, or if you require further assistance!

Good luck 🙂
