In short, I was diagnosing a EDID problem with my 24" Acer.... since I was already in powerstrip playing around I decided to give the laptop's LCD panel a flogging to see if changing the refresh rate had an effect (because its hardwired to the IGP and I figured it's on its own clock). Turned out that with the ATI X1200 IGP I got in the laptop, and messing with Powerstrip, I managed to bump the laptop's LCD to 200Hz -- any more and the panel would shut down in similar glory to how my 24" Acer did during diagnosis. A quick motion blur test scrolling the [H] homepage showed that I got rid of any noticeable blur and that my whites became slightly brighter.
Now the funny part, usually playing with the ATI CCC LCD overdrive (voltage) option does help a bit at 60Hz (middle setting for my laptop worked quite well). At 200Hz, adjusting the LCD overdrive in CCC has no effect, but to begin with there is no blur whatsoever -- I kept it off since 200Hz digital (internal DVI?) is crazy enough. 200Hz = 5ms response time.. no too shabby for a crappy laptop 2-year old panel. Resolution it was done with was native 1280x800... Edit: Had to drop to 96Hz for standby to work (oh well.. 200Hz I could temporarily).
