How to adjust or change a monitor's refresh rate.

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.

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.

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.

How to adjust the refresh rate
Firstly you will need to right click on your desktop background and select Properties.

This will display the Display Properties window as show below.

You will need to click the Settings tab.

Once in the Settings tab you will need to click on the Advanced button.

Then click on the Monitor tab.

Here you can change the screen's refresh rate. Make sure the box next to Hide modes that this monitor cannot display is ticked. After you have selected the refresh rate you wish click OK. 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.

My syncmaster 245 bw will only display a blank screen through the dvi port. Another crt monitor works fine through the vga port . I'm running a nVidia 7800 GS video card.


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.

I have waves on my screen, what do I need to do to get rid of them?


you don't say whether your monitor is crt/tft....

either type the problem is likely to be refresh rate of the monitor...

try this... (xp pro sp2)

  1. Open Display in Control Panel.
  2. On the Settings tab, click Advanced.
  3. On the Monitor tab, in the Refresh Frequency list, click a new refresh rate
  • To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display.
  • The default refresh frequency setting is 100 Hertz, although your monitor may support a higher setting. Check your manufacturer's documentation for information regarding the settings your monitor supports.
  • A higher refresh frequency reduces any flicker on your screen, but choosing a setting that is too high for your monitor can make your display unusable and cause damage to your hardware.
  • Changes to the refresh frequency affect all users that log on to the computer.
good luck, rate if useful please

monitor displaying 'check signal cable'


Make sure the refresh rate is set at 60 hertz before using the new monitor also check the display settings to see if they are set to use the external display also. Yours may automaticaly do this and your partners may not. If this does not help please let me know the type of notebook and monitor. Good Luck!
