Anamorphic widescreen

From Sega Retro

Prior to the release of the Xbox 360 in 2005, it was common to see video game consoles target what was then a standard in NTSC televisions - a 4:3 aspect ratio for displaying images. However, by the mid-2000s the television market had begun to favour the 16:9 "widescreen" aspect ratio, making televisions in the home more in-line with aspect ratios seen in movies.

While widescreen had been around in numerous forms for many years, most consoles producing digital signals were only capable of rendering a 4:3 image. However, safe in the knowledge that this resulting image could be stretched horizontally for 16:9 displays, many developers added support for anamorphic widescreen. Here, a 4:3 image is drawn in such a way that when stretched to 16:9, the proportions of the graphics would appear as intended, offering many of the advantages of widescreen displays without the need to physically render a larger image.

Anamorphic widescreen is not "true" widescreen, as each pixel is designed to be stretched (and so is not square). This typically means the image is blurrier as there is less information across the X axis, however on older televisions, particularly widescreen CRT displays, the artifacts would be less noticeable. With the advent of the HDMI standard, anamorphic widescreen is rarely seen in newer electronics, however remains a common feature for DVD movies.


Virtua Fighter on the Sega 32X supports anamorphic widescreen:

When the game aspect ratio is matched with that of the television, Virtua Fighter looks as intended, otherwise Akira and Jacky are either too "thin" or too "fat". In this case, the benefits of 16:9 widescreen involve being able to see more of the playfield, however this comes at the expense of graphical fidelity. All four screenshots render internally at 320x224.

Sega games which support 16:9 widescreen

Several games for Sega systems support anamorphic widescreen, although unlike a more modern console such as the Wii, the feature was not made a priority due to the limited number of widescreen television users in the 1980s and 1990s. Also in most situations, widescreen support only affects the 3D portions of a game - 2D areas such as menus are usually fixed at 4:3, and so will be streched on a widescreen display.
