I have purchased an HP elite computer and it does not connect to the monitor as it should.

I get the following on my monitor "Input signal not found"  I can do a hard reboot and then the signal is found.  However, if I leave for a few minutes, I will get the same message again.  I have changed HDMI cables and that does not fix it, so I know it is not the cables. How do I fix it  take the computer back to SAMS?

First try a quick reset

Win + Ctrl + Shift + B to restart the graphics driver.

If that does not work then try disabling fast start.

Disable Fast Startup:

• Open the Run dialog box by pressing Win + R.
• Type powercfg.cpl and press Enter to open Power Options.
• Click on "Choose what the power buttons do" on the left.
• Select "Change settings that are currently unavailable".
• Uncheck the "Turn on fast startup" option and save your changes.

Fast start loads a image of the OS that might be corrupted.  It will load the exact corrupted image every time unless you  disable fast start, make sure all is ok, then re-enable it.

see if there is OS corruption

It would be useful to know your exact PC model.

Let me know if still a problem.
