The Enhanced Graphics Adapter (EGA) is a historical IBM PCcomputer display standard from 1984 that superseded and exceeded the capabilities of the CGA standard introduced with the original IBM PC, and was itself superseded by the VGA standard in 1987.
History
EGA was introduced in October 1984 by IBM, shortly after (but not exclusively for) its new PC/AT.
The EGA standard was made obsolete by the introduction in 1987 of MCGA and VGA with the PS/2 computer line.
Shortly before the introduction of VGA, Genoa Systems introduced a half-size graphics card built around a proprietary chip set, which they called Super EGA (later cards supporting an extended version of the VGA were similarly named Super VGA).
Design
EGA produces a display of sixteen simultaneous colors from a palette of sixty-four, at a resolution of up to 640×350 pixels. The EGA card includes a 16kBROM to extend the system BIOS for additional graphics functions, and includes a custom CRT controller that has a backward compatibility mode with the MotorolaMC6845 chip used to generate video timing signals in earlier graphics controllers.
A video card (also called a video adapter, display card, graphics card, graphics board, display adapter, graphics adapter or frame buffer) is an expansion card which generates a feed of output images to a display (such as a computer monitor). Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics. Within the industry, video cards are sometimes called graphics add-in-boards, abbreviated as AIBs, with the word "graphics" usually omitted.
Virtually all current video cards are built with either AMD-sourced or Nvidia-sourced graphics chips. Most video cards offer various functions such as accelerated rendering of 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or the ability to connect multiple monitors (multi-monitor). Video cards also have sound card capabilities to output sound along with the video for connected TVs or monitors with integrated speakers.
We take a deep dive into the EGA Card and look at some games and compare the different resolutions and colour modes of the EGA.

Byte Planar EGA Data - Storing Graphics for the Enhanced Graphics Adapter
A hopefully useful explanation on Storing EGA Planar graphics.
If I continue to do these videos, the following video will try to explain how to convert a 256-color BMP file to 16-color Byte Planar EGA data. We'll see how it goes.

EGA graphic images: Examples for aspect ratio correction.
EGA (Enhanced graphics adapter) was introduced in 1984 by IBM. EGA displays a resolution of 640×350 pixels – nearly 16:9 aspect ratio. But the image was stretched to ~4:3 on the CRT monitor, depending on the user's hardware settings. That's why these images nowadays look distorted on modern screens with square sized pixels.
Correcting this distortion without moiré effect and without subpixels, suitable for high density screens and printing: Multiply the width by 4 and the height by 5. Make sure the "constrain proportions" option is disabled. Resampling option: "Nearest Neighbor" (hard edges). Result: 2560 x 1750 px.

These are something that I wasn't aware of existing! It is a modified EGA (the "Enhanced Color Graphics Adapter") video board, apparently only designed for the IBM XT.

Thank You to Computer Reset for giving me these adapters unannounced - I will need to test the capabilities of these adapters further - I don't know if this was planned to be competition to the Hercules Graphic Card.

Option 2 (Will stretch the image to 4:2.7): Multiply the width by 4 and the height by 5. Result: 2560 x 1750 px.
Conclusion: Which one is best? In my opinion, it depends on the individual graphic. Since everyone – not only the end user but also the screendesigner/programmer was able to change the aspect ratio of their CRT monitor display, some images will look better with option 1 and some with option 2.
Maybe you ask yourself: Is there a way to downscale the result? No - because neither 3 and 4 nor 4 and 5 have a greatest common divisor (gcd). Therefore it is not able to downscale the enlarged images without causing unsharp subpixels or uneven pixel sizes.
You may try out the shown procedures with 640×350 px screenshots of Microsoft Flight Simulator 4.0 for example, which was released in 1989.
The example image (Las Vegas) was drawn by me in 1989 using »PC Paintbrush«.
