New converter chip can convert DisplayPort 2.0 to HDMI 2.1
Parade Technologies, a Taiwanese company, has revealed the development of two processors for converting a Displayport 2.0 signal into an HDMI 2.1 signal.
Even while Displayport 2.0 is not yet being implemented in devices, this does not imply that the advancements are coming to a halt any time soon. This will be particularly beneficial when connecting a future video card to television that supports HDMI 2.1. As a result, you will be able to play games at 4K at 120 Hz or 8K at 60 Hz, depending on your monitor.
All of these are the maximum capabilities of HDMI 2.1, while DisplayPort 2.0 can support a maximum of one 16K monitor (15360 x 8640) at 60 Hz and no less than two 8K displays at 120 Hz, depending on the configuration. Every scenario involves 10-bit color with chroma 4:4:4 subsampling.
The HDMI output can accommodate up to four FRL lanes with a maximum transfer rate of 12 Gbit/s per lane, which is responsible for the signal transfer. It is also backwards compatible with HDMI 2.0 and supports technologies such as variable frame rate, rapid media switching, and automatic low latency mode. It does not appear that the displayport signal can be separated, which would allow you to use, for example, two HDMI 2.1 ports with the vast bandwidth of displayport 2.0 to get the same results.

I'm using cheap DP to HDMI (not active I guess) adapter just for audio and still works. Only tried on nvidia 1000 series. But works fine at every bitrate/frequency.
It won't work on newer cards?

Its not a gfx card issue.
The key is the adapter cable being active (powered from DP/HDMI or an external power supply).
Also, audio still works because windows resamples to 16/48.
High def audio doesnt work unless downsampled, everything must be 16/48 to get sound.
In other words, if you want high definition audio from music or films etc, you cannot with an active adapter.
ps
This is not about the adapter this thread is for.
It might have the same problem, I hope not for everyones sake.
Thats why I posted about it, to raise awareness in case anyone gets caught out.

But, if it just for audio, you can still use a passive one, right?
Wonder how long will this works being such different protocols.
I like cards with two HDMI outputs, but most are 3 DP and 1 HDMI.

Video (for films) has to get to the system as well.
None active DP to HDMI adapter cannot pass UHD video, we are forced to use an active adapter which wont pass high def audio.

Sadly no mention of whether it will pass audio untouched.
Current active DP to HDMI adapters limit audio to 16bit 48KHz,
Lower freq wont work, no audio. Same with higher freq, it has to be exactly 16/48.
This made my DP adapter pointless as I only need it to send a signal to my hifi for films etc to get full bandwidth audio, and it cannot do it!
My new gfx card gets around this with 3 HDMI and 3 DP so I never need another bad performing adapter, it formed a major part of my purchase decision.
Poor show from these adapters.
edit:
It doesnt actually mess with audio, I phrased that badly. It simply wont pass anything other than 16/48.
Because it can only pass 16/48, windows will resample everything to that.
If you try to send audio "directly" (ie ASIO, WASAPI) it must be at 16/48 or there is no audio.
Send a different rate and there will be no audio.
