Custom Aspect Ratio lets developers configure per-session resolutions (320–4096px per dimension, up to 1080p total) to match any player device — portrait, landscape, ultra-wide, or square — eliminating letterboxing via the DisplayConfiguration parameter in the StartStreamSession API. Dynamic Resolution automatically adjusts stream quality in response to network bandwidth changes, reducing resolution when bandwidth drops and recovering when conditions improve; it is enabled by default for new stream groups and requires downloading the new Web SDK. Both features are available across all AWS regions where GameLift Streams is offered. ## Full article daily.dev links to this article rather than hosting it.
