Refresh Rate on Thinkpad

#1 Post by teknoT42 » Wed Nov 03, 2004 1:53 am

Hello,
What do people here have there refresh rates set to? In the display properties I clicked "hide modes that this monitor cannot display" and it is set to 60 Hertz..
Is it possible for me to increase it for better refresh rates or it won't make a differences?
thanks

That option is irrelevant on your ThinkPad, and any LCD panels.. It's meant for CRT monitors, which update the image on the screen by flickering "as many times as your _ _ Hz is set to" per second. LCDs work differently.. You can just ignore that option.

Not completely true. It of course doesn't affect the hardwired visual output of the LCD, but increasing you refresh rate does allow you to speed up the mouse cursor beyond the fastest setting you can achieve in the Control Panel ;)

So what do you have yours set to in that case?

Actually what is the default refresh rate?

In Windows it says it's 60Hz...but through the ATi control panel it says it's 50Hz.

Can someone clarify?

Mine is set to 75Hz. That allows me to sweep the cursor across the entire UXGA screen in less than one full stroke across the touchpad, at highest mouse sensitivity and enhanced pointer precision on, yet still gives me pixel-level precision at low speed.

Setting it to 85hz makes the cursor jump more than one pixel at a time no matter how slow I move it.

I have a thinkpad T42 14.1 XGA monitor...
Do you recommend me set my laptop to 75hz or keep it at default 60?

Setting it at a higher refresh rate should also make your LCD consume more power.

I would not recommend running any LCD display at refresh rate higher than 60 Hz if you care about image quality.
