However, modern LC glasses generally work in higher refresh rates and eliminate this problem for most people. First, the method only worked with CRT monitors. With widespread availability of 3D TV sets and flat computer screens in the 2010–2013 period, [4] flat-panel monitors support high-enough refresh rates to work with some LC shutter ...
60 fps typically, some gaming monitors can do up to 540 fps; internally, display refreshed at up to 540 fps [18] [19] 60 fps typically, some can do 120 fps; internally, display refreshed at e.g. 480 or 600 fps [20] 60 fps typically. Up to 480 fps. [21] Flicker: Perceptible on lower refresh rates (60 fps and below) [22]
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.
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 ...
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.
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 ().
Video modes with vertical refresh frequency being a multiple of 6 Hz (i.e. 24, 30, 60, 120, and 240 Hz) are considered to be the same timing as equivalent NTSC modes where vertical refresh is adjusted by a factor of 1000/1001.
The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
