Changing A LCD 60MHZ Refresh Rate Higher

From what I've read, why tearing with LCDs is common is because of the low refresh rate of typically 60MHZ on most LCDs, but I read that if you change it to a higher refresh you can get away from tearing, like placing it at 75-85.

What do you think about this, how well can a LCD take a change with the refresh without killing it?

This seems like the thing I need to experiment with, picking a higher refresh rate, so I can get away from tearing that I keep getting when I game.

ALOHA

P.S I've tried all options, Vsync, different drivers, etc....
 
Setting a higher refresh rate won't kill an LCD monitor, but most LCD monitors don't really support higher refresh rates. Most LCD monitors will only output 60 frames per second regardless of the refresh rate, so at 75 Hz, it skips every 5th frame, which makes motion seem jittery.

The best thing to do would be to enable vsync.
 
I heard people talking about this as overclocking their LCD, by changing the refresh rate.

Is there something know as overclocking a LCD to have this work?

THANKS
 
LCD do not refesh like CRT's, the refresh rate option is more a legacy thing left over

LCD's change on a per pixel basis.

most LCDs are stuck at 60mhz, some can do 75mhz, but the 60mhz is a limit of the DVI interface, i think dual link allows 75mhz on newer LCD's / vid cards.

The only affect this has is in games which would allow 75FPS max instead of 60FPS max.

if you turn off vsync you can go higher, but you may get image tearing.
 
Ok

I read this about Triple Buffering which might help with tearing.

However it appears that most recent graphics cards and most new games will not experience major problems by enabling Triple Buffering. Given the fact that it can help to both remove tearing while also preventing the significant FPS drop encountered when VSync is enabled, it is at least worth trying for yourself to see the results on your system.

I'll have to look into this setting...
 
the 60Hz/120Hz stuff will only be how fast it will get data from the video card.. LCDs themselves are limited by how fast the panel can change the pixels... But in any case, if the refresh rate goes higher than the pixels can change intensity, it will just create ghosting.
