We’ll have to wait and see... I’ve laid everything out for Twitch Support, but I won’t get a response before tomorrow at the earliest. I’ll check back in here as soon as I know more.
Best regards!

Twitch doesn't have control over the 1440P streaming. They sent me an email telling me that I must just enable EB and set to 3 Video tracks. It will stream smoothly. So, I did it, and it worked for me. I have no issues since I've been streaming last month. 1440P is crisp and very clear. I saw a few 1440P streams and it looked ugly. Mine looks superb and I am very happy with it.

1440P 60FPS streams without issues.

That's strange, though because as far as I know, Twitch has to manually activate 1440p access for your account on the backend.
Otherwise, anyone could just enable it and the whole beta would be completely pointless.

I understand your point of view. But Twitch support told me that they do not have control over that. Do Not expect great news from their Twitch Support team because they will give you feedback that might upset you.

Yes, according to my knowledge, Twitch are supposed to enable 2K on their end, but they do not do it which is weird to me as well. They need to pull up their socks and enable it for our Twitch Accounts. I think, that will be the only way for us to gain access to the HEVC or AV1 encoders if they allow proper 2K access for our accounts.

And yes, not everyone can stream 2K. They need to give you access, but what's the point of the access if we do not get encoder access?

I have exactly the same issues.

- Enhanced Broadcast is enabled.
- Resolutions all set to 2560x1440.
- my upload is 50mbps

I am uploading to twitch with enhanced broadcast 3 video tracks with around 9000.
if i keep max video tracks on auto, its arout 10.000-11.000 (caused by multiple track rendering and streaming).

I analize the receiving stream with: https://inspector.twitch.tv/

which all the time shows:
- the wrong codec. video codec 7 which is h264 instead of hevc.
- the wrong resolution. 1920x1080 instead if 2560x1440.
- the wrong bitrate. 6000 instead of around 7500.

this should be a 2k stream, but it is not:


so something is definitely going wrong here.

as far as i know, the enhanced broadcasting should show multiple video streams in the inspector and not just a single stream. also with a different codec than 7.

I also have 50UL like you. My Bitrate is set to auto. I do not tamper with that. If I do, then I always have issues with streaming 1440P 60.

That would be rough... especially since all the requirements are met: hardware, upload speed, everything.
By the way, I tested it again with just 3 video tracks... still no success.
Whatever’s going wrong behind the scenes at Twitch, they seriously need to fix it.

That is strange. I enable Twitch EB. I do not use Twitch with my stream key because Automatic is recommended. You can change the server though but do not use the Twitch Stream key.

Anyway, I enable EB, then I set it to 3 Multitracks. I leave the Bitrate on Auto.
Video settings: 1440P and 60FPS of course.
Process Priority is set to High.

Then I stream. When I check my VODS, it's 1440P (2K). Only 3 tracks available. 2K (1440P60), 1080P60 and 360P30. Even on 360P30, the stream still looks great for those on low internet packages.

My upload is 50.
Single PC setup.

i also use the twitch connection and not the stream key. I also read somehwere that 2k stream is not working with the twitch key only.
Also the bandwith testing mode is not available if you use stream key only.

No chance... when I switch to 3 video tracks, it only streams at 8000 kbps. Process priority is already set to high.
I still suspect that even though we got the notification in the dashboard, we haven’t actually been unlocked for 1440p on the backend yet.
Why else would it work for others but not for us?

It's best to always test with Twitch Inspector. Then you don't need to go LIVE. You just test the connections and streams. I use Stream Key only whe I do tests. It's much easier to use it with Twitch Inspector.

which obs version do you use?

I just looked into the obs logs and i can see that all enhanced broadcast video tracks are on h264 which is indeed wrong already on the obs client side. this should show at least the hevc codec, which is not there. there is also no 1440p shown, it starts with highest 1080p h264.

so i assume the issue is locally/on obs side and not on the twitch side.

I use obs 31.1.1
