In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).
Computer monitors marketed to competitive PC gamers can hit 360 Hz, 500 Hz, or more. [21] High frame rates make action scenes look less blurry, such as sprinting through the wilderness in an open world game, spinning rapidly to face an opponent in a first-person shooter , or keeping track of details during an intense fight in a multiplayer ...
The first fully mechanical digital computer, the Z1, operated at 1 Hz (cycle per second) clock frequency and the first electromechanical general purpose computer, the Z3, operated at a frequency of about 5–10 Hz. The first electronic general purpose computer, the ENIAC, used a 100 kHz clock in its cycling unit. As each instruction took 20 ...
Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability. The lowest ping physically possible for a connection between opposite points on Earth crossing half of the planet is 133 ms. Other causes of lag result commonly in a lag below a playable 20 ms (50 hz or fps), or in the loss, corruption or jitter of the game.
Nevertheless, this is almost identical to the use of casual stopwatches on two monitors using a "clone view" monitor setup as it does not care about the missing synchronisation between the composite video signal and the display of the laptop's screen or the display lag of that screen or the detail that the vertical screen refresh of the two ...
Closeup of a touchpad on an Acer CB5-311 laptop Closeup of a touchpad on a MacBook 2015 laptop. A touchpad or trackpad is a type of pointing device.Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.
The HP TouchPad was announced on February 9, 2011, at the webOS "Think Beyond" event held at the Fort Mason Center in San Francisco alongside the HP Veer and HP Pre 3. [10] Initial sales of the device sold 25,000 of 270,000 units, and did not meet HP's expectations, rapidly becoming overshadowed by the launch of the iPad 2 in March.
[16] [17] Most studies find that touchpad is slightly faster; one study found that "the touchpad was operated 15% faster than the trackpoint". [18] Another study found that average object selection time was faster with a touchpad, 1.7 seconds compared to 2.2 seconds with a trackpoint, and object manipulation took 6.2 seconds with a touchpad, on ...
