High Dynamic Range (HDR) Support?


(Mark Ludviksen) #1

Hi.  Any chance Zwift will support High Dynamic Range (HDR) in an upcoming release?  I just purchased a new 4K TV w/HDR primarily for use with Zwift and the difference in picture quality with and without HDR is significant.  Please consider supporting HDR in a future update!

I’m running Zwift at 4K with an NVIDIA GTX 1080.

High Dynamic Range doesn’t have anything to do with screen resolution. HDR is a technique used to increase the dynamic range (black/under-exposed to white/over-exposed)  https://en.wikipedia.org/wiki/High_dynamic_range.

While your new tv may use HDR, it’s not referring to the resolution but to the shadows and highlights.

I think what you are looking for is UHD (Ultra High Definition) which includes 4K support https://en.wikipedia.org/wiki/Ultra-high-definition_television

Apparently 2K is already supported: https://support.zwift.com/hc/en-us/community/posts/204705573-QuadHD-and-2560x1440-resolution-support

I’m aware HDR has nothing to do with resolution - I’m already running Zwift in UHD on my 4K TV, but HDR can have an impressive impact on the quality of some images and videos.

that may be true for real life captured videos. since zwift is a cg world i think the impact would be close to minimal.
