The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
The ThinkLight can be activated when the monitor is on or off but not while the computer is off. Some ThinkPads, like the Z and R series (though not all - some R61 and R32 models still have the white light) feature an amber LED due to the lower cost, while other models, like the T series, use a white LED (which is generally preferred).
Each screen character is represented by two bytes aligned as a 16-bit word accessible by the CPU in a single operation. The lower (or character) byte is the actual code point for the current character set, and the higher (or attribute) byte is a bit field used to select various video attributes such as color, blinking, character set, and so forth.

The Connection Machine, a 65 536-processor parallel computer designed in the mid-1980s, was a black cube with one side covered with a grid of red blinkenlights; the sales demo had them evolving Conway's Game of Life patterns. [1] The two CPU load monitors on the front of BeBoxes were also called "blinkenlights". [3]
ThinkVision displays are high-end computer monitors manufactured, designed and developed by IBM and Lenovo.. ThinkVision products are built using the design language of other Think devices such as the ThinkPad line of notebook computers and the ThinkCentre or ThinkStation lines of desktops.
From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. Since 2010, the typical display aspect ratio of both televisions and computer monitors changed from 4:3 to 16:9 [ 1 ]
Displaying any other resolution either requires a video scaler, causing blurriness and jagged edges, or running the display at native resolution using 1:1 pixel mapping, causing the image either not to fill the screen (letterboxed display), or to run off the one or more edges of the screen. Fixed bit depth (also called color depth).
A personal computer, often referred to as a PC or simply computer, is a computer designed for individual use. [1] It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician.
