Computer monitor says no signal

Specs: Windows 10
I recently got a new screen, the Acer LCD K222HQL and am trying to connect it to my computer however it seems that no matter what troubleshooting ive tried it doesn't seem to work. Tried the onboard graphics card and dedicated graphics card, the VGA and HDMI cable, various checks and tried releasing the left over electricity
Motherboard: asus m5a78L-M LE
GPU: GTX 560
PSU: CX 430

No signal usually means that the monitor is OK but there is an issue with the computer. The fact that it shows the message proves it's working. Try the monitor on another computer for starters. If you still have the old monitor does that work on it?

A poor signal cable or its connection is possible.

Always pop back and let us know the outcome - thanks

If you have a graphics card installed, that's what you need to connect the monitor cable to. No adapters should be used.

Don't connect cables with the computer turned on. When starting the computer do you see anything other than the no signal message?

@OtheHill Yes I always keep the computer turned off don't worry. All that shows is the 'no signal' message with no option to get to the monitor's menu settings

@Johnw That's cause this is my first computer and I can't connect it to the laptop cause there's no HDMI mini or VGA slot for it. & I haven't got the normal HDMI cable

OK. Presumably this laptop works OK with its own inbuilt screen?

If you boot up with the monitor plugged in have you ever see anything other than the "no Signal" message. If you have not then you should have seen something such as the Acer logo. Since this comes up before Windows starts then the problem has to be due to hardware in some shape or form and not software (drivers etc).

Monitors will work without any drivers at all. It can be either the computer hardware or the monitor connections that are giving trouble. You ought to try the monitor on another computer just to make sure it is not its internal signal connections that are at fault. Unusual but possible.

Always pop back and let us know the outcome - thanks

OK, As per #3 above, same question as Derek in #10. Also, If you have an add in graphics card that usually disables the onboard graphics. My guess is that you don't have the graphics card fully seated, or if it requires additional power connections, you have not connected them.

If you have a standard size case you need a normal height graphics card. There are low profile cards for slimline cases. If you use the wrong style card you will probably not seat the card properly in the slot.

One last thing is that if you have multiple ports on the card you may be connecting to the secondary which may not work by itself. DO NOT connect or move the monitor cable while under power.

Post all the specs of your hardware. Including CPU, memory, power supply, case, etc.

If this is a new build that never actually ran, you may not actually be posting due to another hardware issue.

"All that shows is the 'no signal' message with no option to get to the monitor's menu settings"

The monitor isn't the problem! It's the lack of video signal getting to it that's the problem. Are you using some sort of adapter? Because the link I posted to your monitor says that it has DVI & VGA, not HDMI.

Take out the graphics card & connect the monitor to the onboard graphics port using the VGA cable. Assuming you get a display, enter the BIOS & check ALL the settings. Adjust as necessary & save.

EDIT: When you had the GTX 560 installed, did you have two 6-pin PCIe plugs connected to the card?
