Microsoft Windows 95 and Windows 98 (First and Second Editions) set the refresh rate to the highest rate that they believe the display supports. Windows NT-based operating systems, such as Windows 2000 and its descendants Windows XP, Windows Vista and Windows 7, set the default refresh rate to a conservative rate, usually 60 Hz. Some fullscreen ...
High resolution monochrome mode using a custom non-interlaced monitor with the slightly lower vertical resolution (in order to be an integer multiple of low and medium resolution and thus utilize the same amount of RAM for the framebuffer) allowing a "flicker free" 71.25 Hz refresh rate, higher even than the highest refresh rate provided by VGA.
On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
The refresh rate of the video signal can be higher than 41 Hz (or 48 Hz) but the monitor will not update the display any faster even if graphics card(s) do so. [citation needed] In June 2001, WQUXGA was introduced in the IBM T220 LCD monitor using a LCD panel built by IDTech.
Perceptible on lower refresh rates (60 fps and below) [27] Depends; in 2013 most LCDs used PWM to dim the backlight [28] However, since then many flicker free LCD computer monitors were introduced. [29] Does not normally occur due to a high refresh rate higher than FPS [30] Does not normally occur at 100% brightness level.
200, or 350 to 410 lines (including 400-line) at 70 Hz refresh rate, or; 224 to 256, or 448 to 512 lines (including 240 or 480-line) at 60 Hz refresh rate; 512 to 600 lines at reduced vertical refresh rates (down to 50 Hz, and including e.g. 528, 544, 552, 560, 576-line), depending on individual monitor compatibility.

LFC helps ensure that when the framerate of a game is running below the minimum supported refresh rate of a display, the frames are displayed multiple times so the framerate remains in the supported refresh rate of the display and smooth gameplay is maintained. [14] AMD FreeSync Premium Pro adds luminance and wide color gamut requirements. [5]
