How to Stream to Twitch Using OBS With An Ultrawide 21:9 Monitor

Streaming on an Ultrawide monitor such as the Acer Predator X34 or the Dell U3415w can be a finicky business at the best of times. This guide should answer the questions: “How to stream using an ultrawide monitor?” and “How to stream with a 21:9 monitor”. I use the OBS or Open broadcaster software that’s absolutely free of charge. It works incredibly well with ultra wide monitors.

I cover how to stream natively at 21:9, also how to stream a game that isn’t support at your monitors native resolution as if it were 21:9. Ultrawide resolutions are classified typically with these two resolutions: 3440×1440 and 2560×1080. It’s a very immersive and useful resolution. Not quite the pixels of 4k, but at 1440 on a 34″ panel, the pixel density is in the sweet spot.

In this guide I show you how to stream Overwatch, Bioshock infinite and Inside using a 21:9 aspect ratio and how to scale it appropriately in order for you to get a quality stream.

    Is it possible to stream with a 21:9 monitor and make the twitch stream see 16:9 ? Without me using windowed mode, wich ruin the purpose of having a 21:9 monitor. Or will my stream always have black bars because I choose to have a 21:9 ?

    What if I have a regular wide-screen monitor and I just want to record & render in this ratio for the cinematic value?

    Thanks for the video, quick question, are you using a capture card as well? would it be best to use a capture card or just the OBS software?

    Can you run a game at 21:9 but stream it in 16:9 and just cut the sides of the image off for the viewing audience, since this is what the game would look like in 16:9 anyway?
