With Windows XP and Dell Latitude docking station, Dell 2001fp set to DVI, goes to Power Save mode and no display. It works fine with VGA input. It had been working fine for ~2 years.

Hi wilhejl,

I see that you are experiencing a video issue with you back light on this case,
you mentioned when docked on your docking station you see the video on you monitor but when undocked you get a black LCD screen and see shadows of what is on the LCD screen.

this is a back light issue that you are experiencing.

We can try and check some settings regarding this concern and se if there is anything we can do to correct what you are experiencing with your laptop

As soon as you turn your Laptop on keep on tapping F1 to will bring you to the BIOS screen if the BIOS shows up on you LCD screen without going black then most probably yo may need to change some settings in windows regarding the the LCD and power options.

• Try docking back into your docking station and inside windows go to power options, and set your system power options to balanced.
• On your Desktop right click anywhere on an open space to get the menu list click on personalize then click on display then click on advance settings, look for screen refresh rate change it to 59Hrtz then undock from your docking station and try booting into windows without using the docking station to check if the video will show on the LCD again on this issue.

I hope that this can help regarding your case,

Have a nice day.

try the display on another computer, if the display does the same thing on another machine, then its definitely a problem in the display not in the computer drivers or bios.

Yes, but you will need a dvi to vga adapter.
Or one of the monitor must have a dvi input.

Either the cable is not connected to the proper port or the display-source is not configured properly.Here's what you can try.

• Ensure that you have connected the VGA/DVI cable in the correct port. If you have an extended graphics card in your computer, use a DVI cable(Digital input) else the VGA would be the only option available.
• If the cable seems to be plugged at the right place, press the first button from the left on the front panel of your monitor (Button 1 shown in the front view: http://support.dell.com/support/edocs/monitors/E228WFP/En/ug/about.htm#Front_View), once. This toggles the digital mode to analog mode of your monitor, and vice versa.
• If the first two steps do not work, its not an issue with the monitor. It could be a failing cable or a defective video card, or the system itself is not completing the POST.

Thanks,
Abhishek

When you change to VGA, you have to change cables to a D-SUB cable. If you want to use S-VIdeo, you have to use an S-Video cable. You could actually have four different devices using the four different cables connected to the monitor one time, and change which one you are looking at by suing the button on the front panel to select the appropriate input.

yeah, you can set the display setting as extension display your DVI

Intel, ATI,Nvidia have tools also to set up,

i have ATI and use the ATI Catalyst tools and autodetect the monitors that i connected to my docking station, intel and nvidia also have this utility.

it depends on setting if u wanted the external monitor as CLONE monitor of your laptop or extension Monitor...

or they might have problem on DVI port of your docking station.

download and install the video utility ( must have .net installed before you install the utility)

the utility will detect your video ports (VGA,DVI,S-video)

let me know the update ..

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

Make sure the proper input is selected

1: D-SUB for Blue VGA cable
2: DVI-D for White DVI cable

The option selected should be indicated on the power save screen.

If changing the input select and rebooting the computer have no effect an no video from the computer is ever displayed, then the monitor is in need of repair.

no vga input message means that the monitor is working fine, and the problem is probably your pc. check the cable connecting the monitor to the pc. if that is ok, you ma have to open up the pc and check some components, most likely the RAM

It is probably either a CCFL back light issue inside the LCD or a set of capacitors on the inverter/power supply board.
Would you be willing to part with it ?
