  2. Refresh rate - Wikipedia

    en.wikipedia.org/wiki/Refresh_rate

    The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image.

  3. Flicker (screen) - Wikipedia

    en.wikipedia.org/wiki/Flicker_(screen)

    The exact refresh rate necessary to prevent the perception of flicker varies greatly based on the viewing environment. In a completely dark room, a sufficiently dim display can run as low as 30 Hz without visible flicker. [citation needed] At normal room and TV brightness this same display rate would produce flicker so severe as to be unwatchable.

  4. Variable refresh rate - Wikipedia

    en.wikipedia.org/wiki/Variable_refresh_rate

    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 ().

    Front and rear views of the TVM MD-3 cathode-ray tube monitor (Enhanced Graphics Adapter era). Note the DE-9 connector, cryptic mode switch, contrast and brightness controls at front, and the V-Size and V-Hold knobs at rear, which allow the control of the scaling and signal to CRT refresh rate synchronization respectively.

  6. FreeSync - Wikipedia

    en.wikipedia.org/wiki/FreeSync

    AMD FreeSync requires the display to pass certification for low latency and refresh rate variation to match the render output of the graphics card. [1] AMD FreeSync Premium mandates further requirements of Low Framerate Compensation (LFC) and at least 120 Hz refresh rate at FHD resolution. LFC helps ensure that when the framerate of a game is ...

  7. Flicker fusion threshold - Wikipedia

    en.wikipedia.org/wiki/Flicker_fusion_threshold

    Some systems could increase refresh rate to higher values such as 72, 75, 100, or 120 Hz to ease this problem, though even if the faster refresh is an integer multiple of the source material framerate to eliminate judder, without higher framerate source material this causes the perception of duplicate images. [7]

  8. Interlaced video - Wikipedia

    en.wikipedia.org/wiki/Interlaced_video

    The higher refresh rate improves the appearance of an object in motion, because it updates its position on the display more often, and when an object is stationary, human vision combines information from multiple similar half-frames to produce the same perceived resolution as that provided by a progressive full frame.

  9. Screen tearing - Wikipedia

    en.wikipedia.org/wiki/Screen_tearing

    That eliminates the stutter that occurs as the rendering engine frame rate drops below the display's refresh rate. [4] Alternatively, technologies like FreeSync [5] and G-Sync [6] reverse the concept and adapt the display's refresh rate to the content coming from the computer. Such technologies require specific support from both the video ...
