Buffering only at 4K HDR10+ — not regular 4K — solved

[mark_wifi]

Hi all! Starting this thread for a discussion on this topic. Looking forward to hearing from the community.

This has been driving me insane for weeks.

HDR10+ is more demanding than standard HDR10. Content requires higher bitrate.

 

[NickCable]

So the bitrate for HDR10+ content is higher than standard 4K?

 

[DonaldTV]

Yes — HDR10+ dynamic metadata adds overhead. Requires ~35Mbps minimum sustained.

 

[CindyApps]

My connection averages 28Mbps. Just barely under what's needed.

Upgrade your router firmware — many 2020-era routers have throughput bugs.

 

[JessicaApps]

Router firmware update gave me 5Mbps extra throughput. Just enough for HDR10+.

 

[JessicaApps]

Also try enabling QoS for the streaming device. Prioritizes its traffic.

 

[LisaCache]

QoS helped more than I expected. HDR10+ is buttery smooth now.

For cable connections: request a line quality check from your ISP. Signal levels matter.

 

[LiamTV]

ISP sent technician who found signal levels 3dB low. After fix, HDR10+ works perfectly.
