27" HP monitor will not wake from sleep-Display shows Input signal not found

[snapper1328]

This monitor is connected to a brand new (2022) 17.3" HP pavilion via and HDMI cable to HDMI port on laptop and have to set the laptop on battery and plugged in to never sleep, I've tried every available solution I googled and nothing has worked so far.  Been this way since I bought both components in March 2022.  When I set it to sleep after 15 min's, and then try to wake, both the laptop and monitor won't wake until I power laptop off and on and display on monitor shows Input signal not found when both the monitor and laptop are both dark.. Any help would be appreciated.

Thanks,

Tom
