Display
Moving onto display, there are many different forms of displaying images to the user, including built-in or external methods, as well as the uses of techniques such as Liquid Crystal technology. I will be covering this and more below, comprehensively explaining this hardware technology much in the same way as the previous pages, and once again relating it back to game platforms. But what comes under display? Well display is how a monitor or other image projection device is made or used to show us whats on screen, and can be altered with any of the ways mentioned above.
External:
An external display is generally anything considered to be a device which allows you to see whats going on on the computer which can be plugged or unplugged. So for example, a monitor is an external display, as it can be interchanged or removed completely. Another example could be a TV, while their main purpose is not for computers, as an external display it can be connected to a computer usually by a HDMI cable to allow it to act as a monitor. This has numerous advantages. For starters, TV's are generally bigger than an ordinary monitor. Secondly, using an external device such as a TV, it is possible to have more than one display available at the same time, assuming the computer has enough ports to support multiple external displays. This can have a variety of uses, especially within the gaming genre. An example of this is that if you wanted to play a game, but also wanted to do something else at the same time such as watch a film or browse YouTube, it makes this possible and easier, not needing to switch and exit programs, as one screen can house one program, and the other can house the other. In addition to this, if a TV were to be the secondary external display, it would make it possible to play computer games on a bigger screen, sometimes with HD options depending on the device. For example, i wanted to have a perfect gaming computer, i would want to purchase the ASUS ROG PG278Q Black 27" Widescreen. This monitor boasts an array of useful and important aspects when it comes to gaming, all of which comes down to the monitor itself, not the computer. Things such as a 144Hz refresh rate, making faster frame rates and minimal motion blur. Or the 2560 x 1440 resolution screen, which allows for 77% more onscreen action, and providing more detail than a convention HD screen, creating a bigger advantage to the player. Unfortunate though, monitors such as this one, priced at $799.99, are extremely expensive, and its often only the most hardcore of gamers who will actually have them. But you can see just how useful an external display is, as it allows you to swap between different displays to upgrade and improve the computers graphics and overall uses easily. This is unlike built- in displays... |
Color:
Color displays for computers are based on cathode ray tubes, or CRTs. Monitors transmit light, and in order to use this to create color for the display, monitors use a combination of three pure colors, red, green, and blue. This is called the RGB model, also known as additives. When combined these pure colors add up to white light, In order to control the color of each pixel on screen, the operating system must use a small amount of memory within each pixel. this memory is called video RAM. or VRAM. the more bits of memory within a pixel. the more variation of colors can be used. So when 8 bits of memory are available, each pixel pixel could be one of 256 colors. this means there can be no more than 256 unique colors on screen at once. This picture shows how a combination of zeros and ones dictate how a color is presented on screen.

Monochrome:
Although monotone usually refers to one color, within computing it often refers to a two-tone image. This can be seen when looking at some of the oldest computers featuring displays, ax they have one color for the background, and one color for the text. The most conversational black background and green text. While this was very primitive,during the 70's and 80's when they were at their peak they still proved to be useful, as they were still a lot more capable than type #writers. However as technology has evolved, and with the addition of tech such as LCD and LED screens, monochrome has become obsolete, and very rare. In computers that is, but it has its uses on other tech such as watched, timers, and digital clocks.
