Hi nobumsteers,

This is most often caused by your VGA cable becoming detached from either the back of your computer or it's connection to the back of the monitor. First, check by unplugging both connections and re-attaching them firmly back into both ends.

If it still displays the no input signal error, then most likely your computer's video card is not transmitting signal to the monitor. So we need to make sure that the video card is working.

If your blue connection in the back of the computer is located near all of the rest of the cables (very close proximity, less than 1 inch apart) then you are using an 'on-board' video card. If you purchase a new video card and place it in one of your lower, available PCI or PCI-Express card slots in your computer and connect your VGA cable to that, you should have video again. But this would be a solution to a defective on-board video card, which if it is still under a warranty should be repaired by your Manufacturer.

Hope that helps.

SOURCE: DVI no input signal......VGA input active.

Are you running an additional Video card? Or are you using the built in one.
You might try cleaning the connector / plugs with acetone from finger polish remover or de=natured alcohol.
Never jam anything on a computer.
If its an add on card, remove it and reboot. Shut down and reinstall card and reboot.
keep me posted please,

I connected up vga and HDMI cables and power, etc to ASUS desktop. All inputs are without signal. If I set monitor for vga, it says no vga signal. Same if set for HDMI input: no HDMI signal.


I would check your source for why it is not sending signal rather than why the monitor is not receiving. Of course, that being said, is this a new monitor or an old one that could be shot?

No signal when i used vga monitor connector to pc, no problem in dvi


Michael,
I have both ASUS and LG monitors with multiple input choices. On both, when the monitor is turned on, it remembers the last input source. Both monitors (and presumably yours, as well) have an INPUT selection in their SETUP MENU.
So, I'm suggesting you search your monitor for an INPUT selection option, then choose "VGA" rather than DVI / HDMI / AV / COMPONENT / CABLE / ANTENNA, etc.
Hope this helps.

No signal


Press the Function Button to open the short cut menu. Locate the Input graphic and press the button for it. Each time you press the button, it will cycle between DVI and VGA input jacks. Allow a few seconds for the display to switch inputs. Make sure that cable is connected securely to the associated jack in the back of the monitor and the computer (or other source). If either VGA or DVI input is selected ,but the VGA and DVI cables are not connected, a floating dialog box indicates:

"No Cable Connect" or "No Signal"

How do I fix the error no vga input signal no dvi input signal monitor going to sleep


Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

Can i connect a dvid cable from the monitor to my flat screen tv hdmi to watch videos from my computer? Thank you Martin


the Flat Screen TV if has, a HDMI input, also has VGA Input.

You must choose :HDMI or VGA, if HDMI The VGA board must Have HDMI Connector, and you connect a HDMI cable to the TV.

The HDMI is a digital signal input/output, VGA is Analog Signal. You must have Signal Converter if you Use the 2 signals
