As for me audio has been OK but recently video that used to stream reliably in 4K / HDR from Amazon Prime via Spectrum (formerly Time Warner) now throttles down every few minutes to 1080p even DVD resolution, then throttles back up to UHD 4K. Repeat every few minutes during the program. I had enjoyed two seasons of Man in the High Castle with UHD / HDR playing reliably for 2 years, but beginning this month, the image is down-throttling every few minutes to a blurry state, then resumes UHD. Seems only to do this dramatically with streamed HDR programs.
At about the time this problem started early this month, Spectrum had just taken over what had been Time Warner (Honolulu) as the internet cable supplier AND I swapped out the modem early this month. Not sure which change (if either) is the culprit.
I am supposed to get 200 mbs download speed (but tests on my LAPTOP at are crazy inconsistent at speedof.me and fast.com (results range from 40 mbs to 210 mbs). At speedof.me the chart of the tests, plotted in fractions of a second, consistently show an unsteady speed with about 5 brief sharp drops to as low as 1000 Kps (yes kilo per, not mega). I'm wondering if these sharp but brief drops are the cause of periodic downthrottling of the resolution. I haven't notice if Netflix is also downressing briefly, maybe they buffer without my notice, but with Amazon on HDR content it is miserably obviously, with a blurry image for about a minute until it throttles back up to UHD.
Could it be the newly swapped modem? It is an Arris TM1602A "Telephony Modem" (I don't recall the model I traded in) received at the local Spectrum office. If I buy my own modem, what models and specs do I need for 4k UHD / HDR streaming? I don't mind price, I have a router but it is old WNDR3700v2 that handles 300mbs, and it did the job reliably and is proven not the cause of the speed test variability (I tested bypassing the router plugging directly into the modem with same results of throttled Amazon Prime streaming and speedof.me sharp drops in speed).
Could it be the LG's Amazon App? I have the LG's 2015 OLED 65EF9500. Using the LG web browser on the TV, I only get 24-29 mbs download at fast.com, and Netflix settings "test your network connection" results max at about 7 mbs which is a puzzle since the LG's browser app tests at 24-28 mbs on fast.com at the same time. But I don't notice down-ressing on Netflix so far (but their 4k has never been quite as sharp - close, but not quite - as Amazon's).
Weird that all these speed tests vary so radically. Here's the summary:
Using laptop direct connect to router: range of 45 mbs - 210 mbs downloads at fast.com. Range of 140 mbs - 210 mbs at speedof.me with 5 sharp drops in speed in every test to around 1000 kps (yes, kilo).
Using LG's web browser, ranging from 24-28 mps on fast.com
Using LG's Netflix app settings: check your network connection: 6.6 - 7.2 mbs (oddly low).
Viewing Netflix UHD programming, appears subjectively to be UHD, haven't noticed sharp drops in reso but might be dropping without my notice to 1080p.
Viewing Amazon UHD / HDR content, the pause/progress bar verifies UHD resolution, until it drops down to 1080 then HD then not even HD, then back up to UHD every few minutes.
Frustrating that Amazon Prime UHD is throttling down when I pay for (and get from moment to moment...) 200mbs download speed. Any suggestions?
