Since you did not indicate what you have done so far, I would suggest the following:
First thing to do is to find out it ias not PC vdieo card problem, try this monitor with other PC and this PC with another monitor to narrow down the problem. Please post back what you found.

If the monitor is showing you a "no signal" message, it's almost certainly working fine. There's no video coming in from the computer, and that's likely where the problem is. Try another monitor first. It's possible yours isn't recognizing the input signal, but it's unlikely. I've only seen that happen twice I can remember. Chances are that another monitor will say "no signal" as well. Either the computer isn't starting up, or the video isn't working.

If you hear all the sounds of a normal startup (usually a single beep when the motherboard finishes power-on tests, hard drive activity shown by the front panel indicator, and finally the Windows startup sound through your speakers), then the video circuitry is bad. If the video is integrated onto the motherboard, you can install a replacement video card in an open expansion slot. If you already have a separate video card you can replace it.

If the computer isn't starting, you need to suspect memory, the motherboard, power supply or processor. You might also have a bad hard drive, optical drive or other device connected which is preventing startup. Begin by unplugging everything except the main parts: memory, processor and fan, power supply and (if used) video card. If the system starts up, you can identify the bad part by reconnecting them one at a time until the problem comes back. If the system still doesn't start with the minimum hardware, part substitution is how you'll figure out which is responsible.

It can be frustrating, but you'll get the thing going. Good luck, and thanks for using Fixya!

Pls help me to make a 1024x768 for my BENQ T52WA lcd monitor. can provide a driver for this.


Need more information. What graphics card are you using and what operating system? Is the monitor connected via DVI or VGA?
If 1024x768 is not showing up as an option when settings the resolution, try updating your graphics card driver.

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

Benq 19' LCD Screen 3 yrs old- no signal detected on brand new PC


Have a look at the back of your computer.

See if there is more than 1 video port.

If there are 2 ports try plugging the monitor into the other port....

Sometimes motherboards have internal video cards, in this case the video port is in among the USB ports, sound and mike sockets etc.

Look for a video port away from all those other things.

"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
