List Of Common Resolutions
This article lists computer monitor screen resolutions that are defined by standards or in common use. Most of them use certain preferred numbers. Computer graphics ; Pixel aspect ratio (PAR): The horizontal to vertical ratio of each pixel. ; Storage aspect ratio (SAR): The horizontal to vertical ratio of solely the number of pixels in each direction.LCD panels' resolutions are often quoted in terms of raw subpixels, misnamed "pixels" in manufacturer's specifications. Each real pixel includes one subpixel for each of three colors, so calling subpixels "pixels" inflates the claimed resolution by a factor of three. This bit of marketing obfuscation is calculated as horizontal resolution × vertical resolution × 3. For example: 640 × 480 VGA is subpixels, or pixels, 800 × 600 SVGA is subpixels, or pixels, and 1024 × 768 XGA is subpixels, but only full-color pixels. ; Display aspect ratio (DAR): The combination (which occurs by multiplicat ...

Computer Monitor
A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid- 2000s, most monitors used a CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals. Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9. Modern computer monitors are mostly interchangeable with televi ...

Epoch Game Pocket Computer
The is a second-generation handheld game console released by Epoch Co. in Japan in 1984 for 12,800 Japanese yen. It is also known as ''Pokekon'' and was one of the very few truly handheld systems to be released in the early 1980s, preceding the Game Boy by 5 years. The system was a commercial failure in Japan, and as a result, only 5 games were made for it. A puzzle game and a paint program were built into the system. It was powered by 4 AA batteries, and screen's contrast could be adjusted by the user. Input and output controls included four buttons, an 8-way joypad, a contrast dial, and a sound on-off switch. Because the Game Pocket Computer failed in Japan, and was never released internationally, the device is extremely rare, and units on eBay can go for hundreds of US dollars. Technical specifications *LC display: monochrome, 75 × 64 pixels * *Power supply: 4 AA batteries *Battery life: Not clear; >70 hours or 60 hours *CPU: NEC uPD78c06 clocked at 6 MHz *RAM: 2 KB *R ...

QQVGA
The graphics display resolution is the width and height dimension of an electronic visual display device, measured in pixels. This information is used for electronic devices such as a computer monitor. Certain combinations of width and height are standardized (e.g. by VESA) and typically given a name and an initialism that is descriptive of its dimensions. A graphics display resolution can be used in tandem with the size of the graphics display to calculate pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display. Overview by vertical resolution and aspect ratio Aspect ratio The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and is now changing to 18:9 for smartphones. The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the ...

Atari Lynx
The Atari Lynx is a hybrid 8/16-bit fourth generation handheld game console released by Atari Corporation in September 1989 in North America and 1990 in Europe and Japan. It was the first handheld game console with a color liquid-crystal display. Powered by a 16 MHz 65C02 8-bit CPU and a custom 16-bit blitter, the Lynx was more advanced than Nintendo's monochrome Game Boy, released two months earlier. It also competed with Sega's Game Gear and NEC's TurboExpress, released the following year. The system was developed at Epyx by former two former designers of the Amiga personal computers. The project was called the Handy Game or simply Handy. In 1991, Atari replaced the Lynx with a smaller model internally referred to as the Lynx II. Atari published a total of 73 games before the Lynx was discontinued in 1995 in preparation for the launch of the Atari Jaguar.

TI-81
The TI-81 was the first graphing calculator released by Texas Instruments. It was designed in 1990 for use in algebra and precalculus courses. Since its original release, it has been superseded several times by newer calculators: the TI-85, TI-82, TI-83, TI-86, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, and most recently the TI-Nspire and TI-Nspire CAS. Most of these share the original feature set and 96×64-pixel display that began with this calculator. Features The TI-81 is powered by a Zilog Z80 microprocessor, like those used in almost every other Texas Instruments graphing calculator (except the TI-80, TI-89, TI-89 Titanium, TI-92, TI-92 Plus, Voyage 200 and TI-Nspire series). However, the processor is clocked at 2 MHz whereas the other Z80-powered Texas Instruments calculators run at speeds of at least 6 MHz (the TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition can run at 15 MHz).
