In both the Apple II and the CGA, each line is elongated to full 228 cycles of the color subcarrier.

Ĭomputers such as the Apple II and the CGA video card for the IBM PC, output a signal that is an approximation of the broadcast standard. This causes the apparent phase of the subcarrier to be reversed every line, which results in solid colors being displayed as a checkerboard-like pattern when viewed on a monochrome display that does not filter out the color information. In the NTSC color system as used in broadcasting, the color subcarrier frequency is exactly 227.5 times the line frequency, i.e., each line contains 227.5 color subcarrier cycles.

Nevertheless, this effect can be exploited by using dither patterns, generating new intermediate palette colors on machines with a sufficiently high resolution display, like the ZX Spectrum, Mega Drive/Genesis, NES/Famicon or Amiga. The exact mix will depending of on the saturation and specific colors of the original pixels. Blurring is a general effect of using a composite connection, that simply creates new colors due to a mix of adjacent horizontal pixel values. Depending on the exact PAL system used results will vary (if PAL-M or PAL-N are used, color artifacts similar to NTSC might be possible).Īlthough related, artifact colors are not the same as horizontal blurring. On PAL displays the effect is also present, but generates more limited colors.

Software tiles (such as King's Quest for the IBM PC) usually provided an option to select between 'RGB mode' and 'Color Composite mode'. It was most common on the IBM PC (with CGA graphics), TRS-80 Color Computer, Apple II and Atari 8-bit computers, and used famously by the Ultima role-playing video games. This mode was used mainly for games, since it limits the display's effective horizontal resolution. With some machines, when connected to an NTSC TV or monitor over composite video outputs, the video signal encoding allowed for extra colors to be displayed, by manipulating the pixel position on screen, not being limited by each machine's hardware color palette. All told, the company says it’s up to 85% faster than the last model, coupled with a GPU that’s up to twice as fast and 3x the machine learning.Example of artwork created with the intent of having individual pixel values horizontally averaged over composite videoĬomposite artifact colors is a designation commonly used to address several graphic modes of some 1970s and 1980s home computers. In addition to allowing for a much thinner design, the new chip allows for far faster performance than previous models - a huge performance bump we’ve seen in our own testing of the most recent generation of Macs. The rear is also flat, instead of curved. The new devices are significantly thinner - with overall volume reduced by half, according to the company. Like the most recent iMac models, it features an anti-reflective coating to reduce screen glare. The display features 11.3 million pixels, a P3 color gamut and 500 nits of brightness. True Tone is, naturally, on board for better color balance, and sound have been improved with six-speaker setup.

The screen sports a 4.5K Retina Display, coupled with a 1080p camera - a first for the Mac line, and a sign the company is taking both audio and video more seriously as these products are serving as a kind of life line for the work from home crowd.
