However, the lower refresh rate of 50 Hz introduces more flicker, so sets that use digital technology to double the refresh rate to 100 Hz are now very popular. (see Broadcast television systems ) Another difference between 50 Hz and 60 Hz standards is the way motion pictures (film sources as opposed to video camera sources) are transferred or ...
A refresh rate of 60 Hz on most screens will produce a visible "flickering" effect. Most people find that refresh rates of 70–90 Hz and above enable flicker-free viewing on CRTs. Use of refresh rates above 120 Hz is uncommon, as they provide little noticeable flicker reduction and limit available resolution.
A depiction of 5 display refresh cycles with what may be shown during a micro stuttering case. Each colored section represents one of the GPU's frame buffer and each color change represents a frame buffer swap. Assuming a 60 Hz refresh rate, a benchmark tool may report this as 144 frames per second.
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.

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 is a type or part of lag that is the rate of a display to produce distinct picture, meassured in Hz (e.g. 60, 240 or 360, that is 16.7, 4.2 or 2.8 ms respectively). [ 6 ] Input-lag
The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate. That can be caused by non-matching refresh rates, and the tear line then moves as the phase difference changes (with speed proportional to the difference of frame rates). It can also occur simply from a lack of synchronization between two ...
For a fixed bandwidth, interlace provides a video signal with twice the display refresh rate for a given line count (versus progressive scan video at a similar frame rate—for instance 1080i at 60 half-frames per second, vs. 1080p at 30 full frames per second). The higher refresh rate improves the appearance of an object in motion, because it ...
