Since CRT is pretty much dead in today's market the only forms of display that will be mentioned are going to be LED onwards. We will also be skipping over display types that are not used with computers such as vacuum fluorescent displays used in clocks and disk displays used in old train signs.

Intro

Screens are the way your computer can show you the amalgamation of all the parts working together. Screens come in many forms at many different price levels and like all components of a computer each type of screen is better for different types of people.

History

Screens have a long past stretching back all the way to 1897 with the first cathode ray tube (CRT) technology emerged and became commercial in 1922. Since then screens have come a long way with plasma, LCD, LED, and OLED each with their own advantages and downsides. In 1968 LED made its debut and would quickly revolutionize screens with its accurate colors and ability to display 32 bit colors rather than 16. In 1986 LCD appeared on the market and it allowed for much higher resolutions to be developed. In the 1970’s plasma blew up but due to its many flaws and competition with cheaper LCD plasma and the the relatively new OLED it is beginning to die out. In 2003 OLED managed to overcome the original flaws of led and is now arguably one of the most promising screen types.

Refresh rate

Screens have a refresh rate which is how many times the screen can refresh the pixels on the screen. The exception to this general definition is plasma which uses pulse-width modulation to create it’s image which results in ridiculous refresh rates such as 600 hz (or 600 refreshes per second) pulse-width modulation is a method by which the plasma is lit up at very quick rates to create an image at different brightness. This is required since unlike other forms of display which can light up and different levels of intensity, plasma works more like an on and off switch. To combat the fact that it can only have one level of brightness on its image it quickly flashes multiple dark images which our brain pieces together into a single bright image. The difference between this and the refresh of LCD and LED is each frame displayed on both LCD and LED is an independently rendered image while a refresh of a plasma is just a copy of a previous image being repeated many times to create an illusion of intensity. When it comes to gaming a high refresh rate can be a valuable asset. For example if someone with a 60hz monitor was to face someone with a 120hz monitor they would only have 60 frames to base the decision of their shot on while the other person would have twice that and therefore could make a more informed shot. Frames per second are not the only measurement of performance however, frametime, the amount of time it takes for you computer to render a frame, can actually be a more important indicator of performance especially in a game. Simply put if frame times are not consistent than even a consistent framerate can appear to stutter.

Sync

This is combated by using vsync, gsync, and freesync. These 3 syncing methods are vastly different but all aim to bring you the same result of a smooth gaming experience. Vsync achieves this goal by syncing your framerate and frametimes with that of your screen and therefore can work on any graphics card. Gsync and freesync however belong to Nvidia and AMD respectively. Both go the extra step and sync your frame times with that of your gpu and displays it on your screen since. This eliminates screen tearing and creates a smoother experience even at lower framerates.

types of cables

Whatever you are displaying your image to from your computer, you will need a cable in order to do so. There are a large variety of cables but we only really commonly use 4. These are VGA, DVI, HDMI, and Display Port. Each cable has it's advantages and disadvantages. VGA is the oldest of the 4 cables listed, and is restricted to a max refresh rate of 75hz, and 1440p resolution. DVI is restricted to 144hz and a resolution of 1440p. HDMI is restricted to a refresh rate of 60hz and a resolution of 4k. Display port, the newest out of the cables, is restricted to a refresh rate of 240hz and a resolution of 8k.

VR

This is a piece of technology simulates being in the environment. The use of VR is to make the user feel inside the image as opposed to looking at it by a screen. The problem with VR is that it takes a lot of GPU power to run. VR is approximately 7 times harder to run than a screen with the same resolution. This is because VR needs a much faster reaction time than your traditional monitor.

Resolution

The resolution of a screen is basically the amount of pixels in a screen. The more pixels along the screen, the more clear the image becomes. So a screen that is 4k or 3840 pixels will have a very clear and sharp image. And an image that is 720 pixels won’t be as clear and it will be much easier to see each different pixel. The most common resolutions are 1080p and 1440p as these have the best balance for price and clarity. A downside to a high resolution is that it uses more power from the GPU, all these pixels are being generated by the GPU and transferred to the screen, the more VRAM a GPU has, the easier it is for that image to be rendered because it can store a lot more information. A lot of people get the size of a screen and it's resolution mixed up, but they are completely different. A 16” screen that has a resolution of 1440p will look a lot better than a 32” screen at 1080p. This is because there are more pixels crammed across the 16” screen displaying a clearer image.
