Hello. It is commonly accepted the Roku Express 4k+ when using a 4k TV when set to a 4k setting requires approximately 25 Mbps +/- 5 Mbps for streaming. Also known as 4K (2160p), this resolution uses five times more data than HD video and requires at least 25 Mbps of bandwidth. HD video uses approximately 5-7 Mbps. Question: When you set the Roku Express 4k+ to 1080p or HD resolution for a 1080p HD TV, does the Roku Express 4k+ INITIALLY transmits approximately 25 Mbps data stream for the streaming app in 4k and THEN DOWNGRADED (backwards compatible) in the final leg of the data stream to 5-7 Mbps ONCE IT REACHES the 1080p TV (in addition, losing the HDR feature when 1080p TV does not have HDR too)? ...or… Does the Roku Express 4k+ when set to 1080p resolution for a 1080p TV transmits AT ALL TIMES 5-7 Mbps from streaming app to 1080p TV like the Roku Express (HD)? Please explain.
I am aware Roku Express 4k+ uses fast wi-fi streaming whereas the Roku Express HD uses standard wi-fi streaming. I would assume the Roku Express HD device when set to 1080p resolution (highest resolution) for a 1080p TV transmits AT A MAXIMUM AT ALL TIMES 5-7 Mbps from streaming app to 1080p TV because the Roku Express HD's standard wi-fi streaming that is the maximum bandwidth and Mbps?
This would mean (if true) the Roku Express 4k+ would need from your ISP a delivery of approximately 25 Mbps +/- 5 Mbps for streaming EVEN IF you had no use for it when you only had a 1080p TV (when the Roku Express 4k+ resolution is set to 1080p)?
