From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A few reasons:

  • Any conversion (including internally at the display) can result in colorspace mismatches.
  • If the sink has an unsupported mode, the source will send a default - which is usually a mismatch.

I wouldn't call it often wrong, personally. I'd say some devices are really bad with EDIDs, and are consistently problematic. It's more like -recent hardware is generally pretty good, but relying entirely on EDID won't always work, so use with care.

Some great examples of problematic devices/situations (in general):

  • Apple. Pretty much anything they make.
  • DP to HDMI - while DP supports HDMI natively, that can be one of the situations where EDID issues crop up. But much less often than....
  • DVI to HDMI or vice versa - this is probably the most problematic of general use. Happens somewhat often where a different or default colorspace gets used.

If you've got a single PC going to a display (or several), just set it once manually and you're good to go. If you're plugging and unplugging often with multiple devices (like with a dock), an EDID minder can be handy, but come with a price that generally makes setting it manually preferred anyway.

Hope this helps answer for you
