You guys with LCD monitors do realise that refresh rate in terms of hertz is irrelevant, right? :yep: (Although the current talk of 180Hz LCD TVs sounds interesting)
Refresh rate relates to CRT screens; CRTs must constantly redraw the screen, since the phosphor layer only glows for a short time. The hertz frequency determines how many times per second that the screen is redrawn.
LCDs don't have a refresh rate in this sense - the transistors on the screen maintain a color and brightness until the video card tells them to change. The total time it takes the monitor to make this change is referred to as the response time and is measured in milliseconds.
LCD monitors include hertz frequencies for supporting analogue connections/video cards (those that need to sync to a refresh rate). Most LCDs, if not all, support 60Hz and 75Hz for this reason. Choosing 60Hz is more than sufficient and actually is of no consequence: 60Hz ~ 16ms - I think all LCD response times are now less than this (mine is 2ms). ;)

Have you got VSync on or off? Try toggling it and see what happens (by rights turning it on should reduce your tearing). |
