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.
However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around a minimum of 200 Hz.
In the demonstration video green and cyan-green are mixed both statically (for reference) and by rapidly alternating. A display with a refresh rate of at least 60hz is recommended for this video. Pausing the video shows that the perceived color of the bottom-right square during playback is different from the color seen in any individual frame ...
Four times the resolution of 1080p. Requires a dual-link DVI, category 2 (high-speed) HDMI, DisplayPort or a single Thunderbolt link, and a reduced scan rate (up to 30 Hz); a DisplayPort 1.2 connection can support this resolution at 60 Hz, or 30 Hz in stereoscopic 3D. 3840×2160 (8,294k) 3840 2160 8,294,400 16:9 24 bpp DCI 4K
DisplayPort version 1.3 added support for 5K at 60 Hz over a single cable, whereas version 1.2 was only capable of 5K at 30 Hz. Early 5K 60 Hz displays such as the Dell UltraSharp UP2715K and HP DreamColor Z27q that lacked DisplayPort 1.3 support required two DisplayPort 1.2 connections to operate at 60 Hz, in a tiled display mode similar to ...
Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions. The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...
The introduction of color television technology made it necessary to lower that 60 FPS frequency by 0.1% to avoid "dot crawl", a display artifact appearing on legacy black-and-white displays, showing up on highly-color-saturated surfaces. It was found that by lowering the frame rate by 0.1%, the undesirable effect was minimized.
When the overall interlaced framerate is 60 frames per second, a pixel (or more critically for e.g. windowing systems or underlined text, a horizontal line) that spans only one scanline in height is visible for the 1/60 of a second that would be expected of a 60 Hz progressive display - but is then followed by 1/60 of a second of darkness ...
