My Samsung Syncmaster 245bw LCD displays a blank screen.
I have checked the refresh rate through the vga port using a CRT, and it is set to 60 Hertz. The Samsung manual has a self test that uplugs the monitor from the computer to see if a test screen displays indicating that there is a problem with the cord. The monitor is still blank so that would seem to indicate that the LCD is broken. Is there any other thing I can check before returning this to the manufacturer? I purchased this through Newegg with their extended warranty. I'm still within the manufacturer's three year warranty, will they opt to repair or the replace the LCD and how long will the whole process take. Thanks for all your help.

Wardysbiz, I should think SAMSUNG would ship you a replacement unit. It might be what is called a REFURBISHED unit of same model.
In future try not to use the word BROKEN. I thought an elephant stepped on it, or it fell from a great height. Try "nonfunctional" or "inoperative", "has failed" , "never worked" "out of box failure" "Dead on arrival unit" Also contact NEWEGG and ask lots of questions about quality and reliabilty of lcd monitors. Find Your sales receipt or card statement to prove pop. Don't let them off the hook!! I would think turn-around process to be about 14-20 days. 12fixlouie

Control Panel Display (or Display Properties) Settings tab Advanced Monitor tab under Screen refresh rate, change to 70 hertz or higher Apply, black screen (Your desktop has been reconfigured. Do you want to keep these settings?) Yes OK OK
If you've ever used a CRT monitor, you know that fine-tuning your refresh rate is essential. The refresh rate of a display is measured in Hertz (abbreviated Hz) and specifies the number of times per second that a display is illuminated.<br />
Setting the refresh rate to 60 Hz - a common default value - tells the monitor to redraw itself 60 times per second. For most people, that setting on a CRT monitor is too slow, resulting in an annoying flicker that can cause headaches, eyestrain, and fatigue. Bumping the refresh rate to a higher number can reduce that flicker, as long as the monitor itself can handle the faster rate.<br />
If you're using an LCD monitor then a safe refresh rate lies in the 60Hz-75Hz range. A greater refresh rate when it comes to LCD's means greater performance.<br /><br />
<b><u>How to adjust the refresh rate</u></b><br />
Firstly you will need to right click on your desktop background and select <b>Properties</b>.<br />

This will display the <b>Display Properties</b> window as show below.<br />
<img src="slasher_x_73.jpg" />
You will need to click the <b>Settings</b> tab.<br />

Once in the <b>Settings</b> tab you will need to click on the <b>Advanced</b> button.<br />

Then click on the <b>Monitor</b> tab.<br />

Here you can change the screen's refresh rate. Make sure the box next to <b>Hide modes that this monitor cannot display</b> is ticked. After you have selected the refresh rate you wish click <b>OK</b>. It would be a very good idea if you have the user's manual for the monitor handy just so that you can see what the manufacturer suggests the refresh rate should be set to.
You need to adjust the monitor refresh rate to 60 Hertz or 70 Hertz. Use the CRT first to adjust it, then after adjust,plug in your Sync Master to see is it perfect or not,find the best frequency that work best.
To adjust it,right click on the screen,enter properties, then click setting tab. Then in advanced tab, click it then you see the monitor tab, find the perfect screen refresh rate.
Hello. That message appears when the video signal from the computer exceeds the monitor's ability to display it. If the sync is set too high(i.e. max sync on the monitor is 60 Hertz at that resolution), you will get that message. Check the video settings in control panel--("appearance and themes" in XP), go to the "advanced" tab and look at the refresh rate. Most computer video cards are able to far exceed a monitor's display ability. Don't exceed 60 Hertz--check the users guide for specs--the lower resolutions can have higher refresh rates(useful in games) Sometimes, a little lower video quality can yield a big performance difference in the display because the screen can update itself faster. (I use a radio control flight simulator pgm that is heavy on video ability).---Hope I was of assistance!---Rick
the monitor gets the wrong signal from the computer (refresh rate too high or scan rate too high ) check the screen refresh rate from Display properties / Settings tab / Advanced button / Monitor settings worse case: damaged hardware
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"
It may be that the LCD monitor will not display all screen resolutions
so you may need to change your resolution to match the desired
resolution and refresh rate of the LCD. In your case the computer
should be outputting:
1024x768 pixels 60 Hz
You can change these settings by right clicking on the desktop and clicking properties and they're under the settings tab. Change the screen resolution by moving the slider to the recommended setting (1024x768)
under the advanced button click the "monitor" tab - make sure the screen refresh rate is set to 60 hertz (60 hz)
Which type of video connector are you using? VGA or DVI?
If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.
Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.
This LCD can work at 75 Hz refresh rate, btw much more healthy for your eyes, you can change it accessing Control Panel -> Display -> settings -> Advanced -> Monitor -> Screen Refresh Rate -> select 75 Hz.
