VGA 1 Detecting prob

Your S-Video connection is referring to a round plug for a TV input signal. Most computers will not have this connection unless you have a TV based video card. If your using a TV 'monitor' as your computer's video device, their will either be a button on the monitor or your remote to allow you to choose the input signal. If you are using a VGA or HDMI or DVI cable as the connector between the two devices, most likely, the light is referring to one of these, as its video source. You will need to match the cable & monitor source detected to get a usable picture output.

Good luck.

Can you observe any LED lights on the monitor panel when you try to turn it on. If no then check your power cables. If you can see the LED lights but screen does not show try to unplug the VGA/HDMI cable and clean it by blowing air through the plug and then reconnect it. Also try to turn on the monitor without connecting it to the monitor as this will verify if the monitor is OK because if it is it should display a message to check the input signal or no input signal is detected. If it does and you are still not having a display then the problem is probably in your CPU and more specifically in the VGA card.

well why not test it on another system
DT or LT
desk top or laptop.

why connect 2 data cables at once, this is SO wrong.
only 1 at a time.

wow ,, why not test the monitor on any other PC or laptop.
see if its good or bad.?
this is the only way to find this, unless guessing works.

i got lost in your post.
try 2 machines
the post photos of what screen does bad, words never work for telling graphics./

Try searching google for your monitors model name and "driver"

That "red white green and blue" block is a color pattern tester. that means the monitor is on, but is not receiving a signal, so its running tests. If your monitor has Digital input and VGA input, you may just need to switch inputs. Look for 1 or VGA if youre using the blue hook up. look for 2 or digital or dvi if youre using the larger white hook up. Some monitors also have 'auto detect'. If you are in "auto detect' bbut the color box is still there, then your monitor is not receiving video signal from the computer. It could indicate a bad cable or no signal being sent by the machine. If you try another monitor, you can see if the machine is working. I would try a monitor setting for VGA-1 first, since thats most common.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

The picture of no input goes off because monitors that do not recieve input go to sleep mode in an instant.

There are four possible causes. First, the cable is not firmly connected to either port, or the cable is damaged. Second, your graphics card could be damaged. Third, the resolution currently set for the machine could be set to a resolution that is too big for your monitor to support, or four, you could have switched your video input. You can change the video input from VGA to DVI and vice versa using the monitor's buttons. The input you want to recieve is from the VGA, though you are probably recieving DVI right now. Apart from that, I cannot help you further as you are not too specific with your information.

Check all of your cables - VGA / DVI mainly in the back of the monitor and the back of the PC.

Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement
