My monitor does not have a remote. Since my computer does not come on screen how do I shut off power saving mode

Hi,

Yesterday, my monitor worked fine. Today, l connected it to a different computer just as a test to diagnose the monitor problem on that computer. This monitor again functioned properly on the second computer. Then, l brought it back to the original computer and reconnected, found everything as normal.

When l turn the computer on, the monitor shows the brand name screen and then goes to a black screen with the "no signal" message.

I know the computer is functioning because l can hear the welcome sound even though nothing shows on the screen.

I have tried unplugging/re-plugging and removing/replacing the CMOS battery. No succe...

Hello,
I am trying to connect my laptop to a monitor. The monitor worked fine with a pc when I last used it, a while ago. I have recently used the same laptop with another monitor, and that worked fine. But those two together... the best I managed was to get the monitor to show me the laptop's desktop for 2 seconds before going back to safe mode. Any idea what's going on??
Thanks in advance!
