My samsung syncmaster 740bf monitor has developed a problem, a few minutes after start up the monitor screen just goes blank (white), but you can be able to0 revert back to the normal screen by pressing...

White glowing screen is indicating that the T-CON board on the LCD panel assembly is not getting the signals or voltages from the main board, you may inspect the caps in the power supply and in the main logic board first.

I have this monitor hooked to my PC ATI 7500 graphics card with a DVI cable. When the PC initially boots up, the monitor display is blank - it does not display the boot-up messages until the MS Windows...

This is normal. Your monitor has a VGA hook in for regular definition. What it is doing, the monitor always by default looks for the VGA hook first. On my desktop it does the same thing until it finds a signal on the DVI.

"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

Monitor dark only when display PC, normal TV

hi have you checked your PC output? check it with another screen (whichever) and see if the output signal is good if soo check the cable and connections to your LCD check your PC for software configuraitions: 1) TV output 2) good resoulotion 3) media borad is strong enough to handle this LCD if all is good then maybe the TV borad is sending a low voltage/current then the LCD can see good luck
