Solved No Signal.

Moved house two Windows 11 PCs all up to date etc.
New house connect PCs with there monitors switch on......PC and monitors power up......No Signal indicated from both monitors.
Started with one set up and swapped monitors and cables between the two set ups.

Idiots guide Please!.

A loose connection between your monitor and your PC will trigger the monitor's no-signal issue. If you're seeing the no signal message on your screen when your Windows system is running, the first thing you should check is whether your display cable is firmly connected or not.

Also try all monitors on same working video port as the video port can be faulty.

Update your graphic card driver.

What happens when you boot into BIOS setup screen.

Try motherboard video port.

Check your monitor and make sure it did not jump to another input, check cable, HDMI cables can go BAD, if it is VGA or DVI check that all pins are straight and not bent or recessed. Make sure your plugged into the GPU and not the internal graphics, Try connecting system to a Different Display

Thanks.
Tried the two cables in both PCs and in both ports on each PC as well as the two monitors in both PCs
Can't, don't know how to progress because the monitors don't respond with an image....just blank.

Problem solved.
I had connected the cables at one of the two connections at the top of the PCs and not into the pair at the bottom of the PCs.

Thankyou all the same many apologies

I presume that you mean that you connected to the graphics ports on the PC case, rather than the (correct) ones on a discrete graphics card. Is that right?

Yes!
