My Samsung Syncmaster 245bw LCD displays a blank screen.

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 /> <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 /> <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 /> <img src="slasher_x_72.JPG" /> <br /> This will display the <b>Display Properties</b> window as show below.<br /> <img src="slasher_x_73.jpg" /> <br /> You will need to click the <b>Settings</b> tab.<br /> <img src="slasher_x_74.JPG" /> <br /> Once in the <b>Settings</b> tab you will need to click on the <b>Advanced</b> button.<br /> <img src="slasher_x_75.JPG" /> <br /> Then click on the <b>Monitor</b> tab.<br /> <img src="slasher_x_76.JPG" /> <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.
