Twitch TV launches dual format streaming and 2K video in June

Dual Format Streaming: A New Era for Twitch

Twitch has officially rolled out dual format streaming and 2K (1440p) video for all streamers. Starting June 2026, every creator on the platform can stream in dual format, while partners and affiliates gain access to sharper 2K resolution. This update marks a significant leap in streaming quality, powered by Enhanced Broadcasting technology.

Dual format streaming allows broadcasters to simultaneously output in both standard and enhanced formats, ensuring viewers get the best possible experience regardless of their device or connection. For 2K streaming, Twitch has bumped bitrates up to 9 Mbps for 1440p and 7.5 Mbps for 1080p, delivering more detailed and consistent streams even during fast-paced gameplay.

What 2K Streaming Means for Creators

With 2K streaming now available, creators can offer their audiences a noticeably sharper picture. The 1440p resolution provides more detail than 1080p, making it ideal for showcasing intricate game environments, high-quality artwork, or detailed IRL streams. The increased bitrate ensures that motion remains smooth and artifacts are minimized.

To take advantage of 2K, streamers need a compatible setup: a GPU from Nvidia GeForce GTX 900 series or newer, or AMD RX 6000 series with updated drivers, plus a minimum upload speed of 12 Mbps. OBS Studio version 30.2.2 or later is required, and Windows 10 or newer is recommended. The process is straightforward: enable 2K in your Twitch creator dashboard under Stream settings, then configure OBS with a 2560x1440 canvas and an output resolution of 2560x1440.

Enhanced Broadcasting and HEVC Codec

One of the key technologies behind this upgrade is Enhanced Broadcasting. This system automatically generates multiple output streams at different resolutions and bitrates, so viewers receive the optimal quality for their connection without the streamer needing to configure multiple profiles. It reduces buffering and improves accessibility for viewers with slower internet.

For 2K streaming, Twitch is using the HEVC (H.265) codec instead of the older AVC (H.264). HEVC delivers higher quality at lower bitrates, meaning a 9 Mbps HEVC stream can look as good as or better than a higher-bitrate AVC stream. This efficiency is crucial for reducing bandwidth strain on both the streamer and the platform, while still providing an upgraded viewing experience. For 1080p, AVC remains available, but HEVC is the default for 1440p.

How to Get Started with Dual Format and 2K

Setting up dual format and 2K streaming is simple. First, log into your Twitch account and navigate to the Creator Dashboard. Under Settings > Stream, you'll find the options for Dual Format and 2K Streaming. If your channel is eligible (for partners and affiliates), you'll see a green indicator. Toggle the features on, then configure your broadcasting software accordingly.

In OBS, set your canvas resolution to 2560x1440 and your output to the same. Under Output settings, select Advanced mode and choose the NVENC H.264 or HEVC encoder depending on your GPU. For Nvidia GPUs (2000 series and newer), enable HEVC and set a constant bitrate of around 9 Mbps for 1440p. For AMD GPUs, use the H.265 encoder. After setup, go live and Twitch will automatically handle the rest, delivering your stream in both dual format and 2K where supported.

Viewer Experience and Platform Benefits

For viewers, the improvements are immediately noticeable. Dual format streaming means mobile users get a version optimized for smaller screens without the streamer needing to manage a separate stream. Meanwhile, desktop viewers with good connections can enjoy the full 1440p experience with higher bitrate. Twitch is promoting these new streams on the app's home page, making it easier for audiences to discover high-quality content.

This update also levels the playing field for streamers who previously had to use third-party services or workarounds to achieve 1440p. Now it's a native feature, reducing complexity and ensuring consistency. With the HEVC codec, the platform can support higher quality without overwhelming bandwidth limits, setting a new standard for live streaming. As more creators adopt 2K, viewers will come to expect sharper, more immersive streams from their favorite channels.
