Thanks for replies . Thing is the computer does not go to sleep as the monitor appears to be doing ( and shouldn’t while watching or listening to something on YT or elsewhere ) ; and , for example , the video on Youtube will pause until I move the mouse after getting the monitor on again . Never experienced this before getting the new monitor .
Maybe this is a new tweak from Microsoft to help users stay active.
You have Windows 10, I assume?
You say the computer does not go to sleep, yet there are programs pausing and waiting for input, unlike if it was just the monitor, the screen would go black but the video and audio would keep playing.
First thing, check those power settings in the Control Panel as you were told upthread. Make sleep/hibernate = never.
The only other thing I can think of is that the type of connection you’re using for the monitor is different than the old one.
If you changed the connection over to HDMI, that could cause some of these symptoms. HDMI is an audio AND video output. Make sure to check your audio devices in the Control Panel and if you have separate speakers plugged into sound port in back, switch over to that sound port as the default sound device.
If you are using speakers built into the monitor, then that’s probably the entire problem there. Once you use the Menu function on monitor itself to turn off sleeping, those should work fine.
Same answer as I gave you above. The monitor power setting is right below the computer sleep setting.
You might look it up on line and even see if there are any Q&A sites about it.
If it's the only thing that changed, there may be a setting within the monitor, in the monitor settings available via the computer (right click on desktop and choose one of the "graphics" options) or maybe some drivers that need to be downloaded/activated in order to get full control.
If you can't figure it out and can supply the info, I'll be happy to take a gander on line to see if there's anything out there, but you may be able to find it yourself - let me know.
