DisplayPort: A Better Video Interface
(hackaday.com)
Wow, learned quite a bit from that
I just wish display port hasn't been "the up and coming new, better standard" for nearly 20 years.
I remember being a teenager researching my first build and thinking 'I'd better make sure I get a display port compatible screen, or I won't be able to use it with a GPU in 5 years!'
It's kinda funny cause my work computer had vga and displayport and not hdmi. Nice to learn why the adapters are the way they are
Some of the screens at my work place, that are less than 5 years old, lack displayport
The computer I use as a home server now is like that, it's an HP Z600 from 2006! Blew my mind last time I had to move it and I couldn't find the power cord to my old VGA monitor.
if displayport isn't backed by home media interests then why did they implement hdcp?
probably to support devices that only work with it enabled
Does anyone know of some affordable 4K@120Hz TVs that ship with DisplayPort interfaces, or any long fiber optic DisplayPort cables supporting the same resolution frame rate and bit depth as the HDMI 2.1 fiber optic cables on the market? That's one thing that's been holding me back from DisplayPort adoption.
It's difficult to have. The members of HDMI Forum are almost the TV manufacturers and the members of VESA (the maintainer of DisplayPort) are PC and GPU munafacturers. So TV almost uses HDMI and monitor almost uses DisplayPort.
This kind of splintering is really unfortunate. Would be nice to have a universal AV interface for consumer hardware. I'd also like to see one that supports bi-directional communication, like for forwarding human interfaces connected to TVs, like wireless game controllers, or programmatic control over internal settings like audio volume, brightness, contrast, motion smoothing, etc. I suppose displayport over thunderbolt plus embedded USB hubs in computer monitors gets close, but the display settings controllers usually require proprietary drivers and are vendor specific.
I know both HDMI and Displayport enable remote control for basic features like turning the device on or off from sleep, but very few PCs or GPUs ship with HDMI-CEC. I've only seen a few mini PCS or single board computers ship with that.

DisplayPort have DDC to control display settings. But I don't know how much settings was standardized and implemented by vendor. But at least, the backlight was implement by most vendors, many users use it.
