That said, just because you can’t disrupt the HDMI process on a bits-over-wires scale, that doesn’t mean you won’t run into EDID problems when you have a complicated setup with lots of HDMI souces or transfer steps. There’s not a way you can “break” the EDID process because you’d have to be messing with the pins on the transfer cables, or modifying the hardware and code on the respective devices motherboards. This is kind of like how HDMI ARC works, except HDMI ARC and eARC are more about the video content and how it should be represented, not the hardware capabilities.Īnd the EDID standard is so baked-in to modern video formats that it’s kind of hard for things to go wrong. The cable has channels that are specifically used to facilitate this “handshake” process, and it happens instantly when the screen and video source are connected and powered on. How Does HDMI EDID Work?ĮDID works by establishing a connection between the screen and video source in which they exchange data via a “handshaking” process. However, with more complicated setups, you might run into obscure HDMI EDID issues. When connecting one device to one other device, this is usually true. Usually, this is part of the “magic” of HDMI: something behind the scenes you never have to think about. When using HDMI, the EDID from your television tells the video source what the dimensions of the screen are. It’s such a reliable and simple standard, in which connecting devices usually “just works” without a hitch, that it’s easy to forget there are some interesting things going on under the hood, like HDMI EDID.Įxtended Display Identification Data (EDID) is a metadata standard that lets display devices like monitors, televisions, and projectors communicate their capabilities to the video source. Option to automatically launch at login.The HDMI format pulls off a neat trick of simplifying video transfer in your home theater (more on HDMI devices like switches in our guide).Labels can be added and customised for any resolution on any screen, making it easy to find your favourite resolutions.User-friendly labels are displayed beside resolutions, such as "Best for Retina Display", "Native", "1080p NTSC".Recently selected resolutions are remembered for each screen.HDTV smart: TV resolutions such as 1080p, 1080i, 720p are all listed when available, including refresh rates such as 50Hz/60Hz, making it easy to find the right HDTV resolution.Retina native: Native Retina display resolutions can be selected, such as the full 2880 x 1800 pixels on a 15" Retina MacBook Pro.Retina smart: Resolutions are grouped by Retina and non-Retina modes (only when Retina modes are detected by the system).Note that EasyRes does not have privileges to create new or alternate resolution modes.
