Please provide some more information ( like when u plug in /on your monitor is it showing some raster or u feel the crt is charging or not?) any way after reading the information u provided it seems that your monitor is remaining in standby mode , possible reasons for this problem are the following:-

1. monitor is not sensing video signal.
2. monitor's microprocessor is faulty (remains in standby mode)
3. monitor's memory chip is faulty.

COMPAQ W17Q MONITOR CANNOT UNLOCK OSD


Here is the link to the monitor manual:
http://h10032.www1.hp.com/ctg/Manual/c00881436.pdf
If you can operate the OSD menu, try resetting.
I have noticed in the past that Compaq products have proprietary wiring schemes for their cabling. If you are using a VGA/SVGA cable (D-Sub) make sure that all the pins are present and wired. A pass through type cable will ensure that this is done.

Today I received a faulty Monitor Dell E773c, the problem is that the Monitor get On and the power LED is Green and after remove VGA Cable from CPU it get Orange, But no Display (The Screen is Blank)


To get monitor work for you, you should connect the VGA cable to CPU. When you remove the VGA cable, monitor has got nothing to display so it goes in stand by mode with orange LED on.

* Make sure the cable is connected properly.

* I've you have mutiple interfaces like HDMI & VGA, try switching between these until you get a signal :D
This can be performed by using the build-in options menu.

I would like to remove the OSD warning pop out "Attention" from my monitor. What I need to do to achieve this?


If you are getting a message that says something like "Check cables" " no signal detected" or something like that, it is likely that your monitor is operating correctly. I would suggest checking your cables, make sure that the computer is turned on, and if that doesn't help, check if your monitor has VGA, DVI, or HDMI inputs. I am thinking that your monitor may be trying to display from the wrong source. This is what a VGA (analog) cable looks like. VGA cables are typically blue.

Another common connection that is used is a digital HDMI (left) or DVI (right) connection. DVI cables often have white end connectors. How your PC connects to your monitor will determine the source mode you want to use on your monitor. (Obviously this is the cable view but the connection on the monitor itself will look similar.)

If none of these tips helps, I would suggest hooking the same monitor up to a different PC or laptop, and trying once again to get a the display working. Again, make sure that the connection matches the source setting on your monitor. If it works on another PC, then your computer may have a video problem.
Otherwise, if it still does not work your monitor have a problem displaying via that connection. If possible I would suggest switching to a different type of cable and re-try the above steps.

My monitor is showing osd locked? what to do


If you disconnect the monitor signal cable and power the screen down, it should auto select VGA next time you power it up. In my experience flatscreens default to VGA to the extent that you can't persuade them to accept a DVI cable instead once they've been powered up with a VGA cable.

You should also be able to access the monitor setup OSD, even with no connection to the computer.

LCD Monitor Blank/Non-Responsive - Dell E173FPC


Next thing I would check is the VGA cable between PC and monitor.

Make sure is in at both ends and if possible try another one.

Do the Dell Menus come up with no VGA cable plugged in? Is the light amber? Flashing or static?

"No signal detected" when LCD connected with DVI-D Cable


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

Check signal message when data cable unplugged. blank screen when data cable plugged


This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
