The result was that the screen often displayed random horizontal black stripes on screen when there was heavy access to the video RAM, like during a video game. Most systems avoided the problem by having a status register that the CPU could read, and which showed when the CPU could safely write to the video memory.
The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel monitors, televisions, and other displays to stands or wall mounts.

The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
The main figure shows 4:3 and 2.40:1 rectangles with the same area A, and 16:9 rectangles that covers (black) or is common to (grey) them.The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.
A flat-panel display (FPD) computer monitor A cathode-ray tube (CRT) 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.
Windows 98 has a credits screen Easter egg, which can be triggered by invoking weldata.exe with the argument "You_are_a_real_rascal" in the command line or a shortcut (.lnk file), or by clicking and dragging between the locations of Memphis, Egypt; Memphis, Tennessee; and Redmond, Washington on the Time Zone map.
If large areas of the screen are taken over by the patterns, it may be more efficient to blit the background to the screen instead of erasing each pattern individually. A variation involves dividing the screen into segments and erasing only the segments where patterns have been drawn on. This technique is known as dirty rectangles.
An application of this kind is enumeration of "maximal white rectangles" in image segmentation R&D of image processing and pattern recognition. [6] In the contexts of many algorithms for largest empty rectangles, "maximal empty rectangles" are candidate solutions to be considered by the algorithm, since it is easily proven that, e.g., a maximum ...
