"a 27 GB file would take just under 2h 09m to download at a perfect 30 mbps " roger that. at 30mbps downloading over the typical movie lenght of 2 hours. and since hdmi 2.0 allows for 18 gbps, there should be no buffering. I agree, pick another source. cheers and happy new year.
Don't forget, that's in an ideal world of absolutes where no other outside factors (other than the source itself) can also affect optimal performance
!!
A "source to slow" warning can be generic & subjective apps can't always account for the bottleneck potentially being at your end. The app merely recognises that the data isn't streaming in fast enough.
Is your peak bandwidth also "up to 30mbps", (as rated by your ISP) or "guaranteed 30mbps"? More often than not the stated maximums just aren't constantly achieved anyway, (especially with non-fibre based infrastructure if that also applies to you). Actual download speeds are subject to a degree of fluctuation based on a number of other various factors, so bear that in mind as well if changing sources doesn't seem to make much of a difference either.
Yes, you could use a rough average of "2 hours per movie" based on historical data, but obviously that figure is also far too inconsistent to guarantee that you won't experience constant buffering with some files. Ergo, it would be useful to allow for some additional headroom overall when calculating your media duration/file size vs available bandwidth, & be more flexible with calculating the duration too.
Obviously we're discussing streaming/downloading files from 100% legitimate & legal sources here too
. The best alternative that a lot of subscribers often prefer if they're restricted as such by limited bandwidth is simply downloading your larger UHD media files in advance & avoid any buffering completely. Granted, that obviously takes away the convenience of a true "on demand" experience that many subscribe to these days. Either that or simply stick to FHD until you can arrange the extra bandwidth, (if that's even possible for your area etc.).
If you still have any ongoing concerns regarding HDMI 2.0 itself or the efficacy of your subjective setup anyway, (U9-H -> AVR -> TV)?? It wouldn't be a bad idea to download some free 4K sample files to fully test your system for any local bottlenecks that doesn't involve your internet connection. (A quick Google search for 4K samples will give you a number of options to help you test your system in general
.)
When all is said & done, whichever options fit in best with your subjective requirements & setup
.
Hope you can improve your buffering issues!!
Indeed, happy new year

(P.S. The above is not a lecture lol
. Some of the points you've raised that have been discussed have come around quite frequently under other separate threads. It felt like a good idea to put the additional information all together under one thread now should any members/guests be searching for the same information in the future.)
