I still miss DVI.

I don't miss it, DisplayPort is a really good replacement.

It is. And this is the likely to be the solution to this issue. DP is a VESA standard, and its Dual Mode feature supports passive adaptors for, among other things, HDMI displays. I use one on my 20-series RTX card.

A cheap DP-HDMI dongle makes all this go away. As long as VESA doesn't behave the same way, anyway.

I think the connector good be better in terms of reversibility and none of that weird locking it has but it's an incredible technical achievement. And it seems perpetually ahead of HDMI in terms of features and Bandwidth.

You can even get cables that are DP on the input and HDMI on the output with minimal bulk.

If I understand it correctly, you can do that, but you cannot call it "HDMI compliant" or otherwise use the HDMI trademark.

Someone without contracts with the HDMI Forum can probably release a working driver. However, AMD obviously needs to license the logo for their GPU boxes and their legal team have decided this prevents them releasing any source code based on the private specification regardless of what the code is called.

> you can't make an open source HDMI 2.1 driver because some people said so I don't understand. Fuck whatever committee said whatever crap. Open source is open source. Just make the damn driver and give the suits 2 middle fingers.

As a Member of HDMI-Forum AMD would surely break its Forum Membership contract by open-sourcing their implementation of a specification restricted to Members.

Also, "HDMI" itself is a trademark with usage only allowed to its Members (like "Wi-Fi"), so even if a non-Member would do an open-source HDMI-implementation against the will of the HDMI-Forum, he would likely not be allowed to call it "HDMI" (like "WLAN" is used by companies without Wi-Fi Alliance Membership)

I've decided to skip 4K for now (at least a decade), switching to the 2560x1440 resolution (finally switched from 1200p)

I normally run it on 120Hz over DP, but it will work fine over HDMI 1.1 at 60Hz. My (5+ years old) TV runs at 1080p/120Hz just fine too.

Also, that someone without contracts would probably need to call it different than "HDMI", because the term itself is trademarked and only licensed to Members (like "Wi-Fi" and "Bluetooth").

So a different term would be needed (like "WLAN" or "BT" is used by non-members)

Locking is a feature, not a bug
