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.

That works somewhat well for 1080p but all adapters I have seen max out at 30fps for 4K video. Might be ok for movies but gamers might not like it.

55" monitors with DisplayPort do exist but they are only a selected few and seem to cost 4 times the price of a 4K TV.

So 4K is still pretty much a luxury that I will just ignore for now.

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

But this feature works by transmitting HDMI signals so you still need to implement the software part in question.

No, it doesn’t. Hdmi alt mode doesn’t exist in the real world.

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.

Not for the past few years. Although DP 2.0 has been 'released', there are no products actually shipping with it, and in practice DP 1.4 is the latest standard. DP 1.4 can't transmit 3840×2160 at 4:4:4 144 Hz without Display Stream Compression (DSC). HDMI 2.0 can.

Here's a GPU with DisplayPort 2.1 https://www.mindfactory.de/product_info.php/16GB-Sapphire-Ra...

Here's a Display with DisplayPort 2.1 and higher Resolution&Refresh Rate than you specified https://www.mindfactory.de/product_info.php/57Zoll--144-78cm...

That monitor was released not three months ago; I was describing the 99.99999% case. DP 2.0 is rare enough that an article[1] was produced this year about its scarcity.

Is there a point for a monitor to use DP 2.0 when the only formats it can display are all supported by 1.4?

And there is DP-Alt for USB Type-C, which makes it much nicer than a regular DP connector.

Locking is a feature, not a bug
Re:You can't make an open source HDMI 2.1 driver by dtx1 on Friday March 01, 2024 @05:11AM (#39560358)
Locking in general yes, the specific implementation of locks on the DP Plug are annoying.
Re:You can't make an open source HDMI 2.1 driver by oskarw85 on Friday March 01, 2024 @09:39AM (#39562196)
Especially when your monitor falls down from your desk instead of simply disconnecting at the plug.

Easily solved by proper cable management.
