Note If you change the video refresh rate to a setting that is not supported by the monitor, you can damage the monitor. See the documentation for the monitor or contact the manufacturer of the monitor to determine compatible refresh rates
before you change the default refresh rate setting for your video adapter.

To determine a refresh rate setting that is supported by both your video adapter and the monitor, follow these steps:
a. Click Start, point to Settings, and then click Control Panel.
b. Double-click Display.
c. On the Settings tab, click Advanced or Advanced Properties.
d. On the Monitor tab, make sure that the monitor is selected. If an incorrect monitor is selected, or if a standard or unknown monitor is selected, click Change, click the manufacturer and model of the monitor, and then click OK.
e. On the Adapter tab, click the Refresh Rate box.


1. Click Start, click Run, type dxdiag.exe in the Open box, and then click OK.
2. On the More Help tab, click Override.
3. Click Override Value, type a refresh rate setting in the Override Value box that is supported by both your video adapter and the monitor, and then click OK. Try one value at a time.
Note Typical values are 60, 62, 72, and 75.
4. Click Exit.

My slider doesn't show 640x480. All refresh rates are 60Hz.

Did you follow the steps above to determine a refresh rate that is supported.

follow instructions above and set refresh rate to 75hz

Here is what is recommended for your monitor taken right off the LG site

1280 x 1024 @ 75Hz
720 x 400 @ 70Hz
1152 x 870 @ 75Hz
640 x 480 @ 75Hz
1024 x 768 @ 75Hz
640 x 350 @ 70Hz
832 x 624 @ 75Hz
800 x 600 @ 75Hz

Putting it in 75Hz worked. Thanks.

No problem thank you for letting me know

Hello Dear, my name is Waseem Dabbas, and I was searching in the internet, then I found this post, What I wanted to ask is:
How can I make my desktop Resolution = 640 X 480 ?
I follow steps that you wrote in post, but in second line, you wrote "settings tab"... where is it in registry editor? I'm using windows XP, I didn't see "settings tab" in registry editor, I hope if you guid me, and I'll be very thankful.
waiting for your reply.

Thanks for reading.
Bye

You should not be editing the registry, unless you have a different problem where that resolution is not an option.
