Roku 2 (4205) Poor Amazon Prime quality

OK - Amazon Prime video is supposed to adjust to the bandwidth - we have a very good connection, other streaming services are fine.

But on the Roku the quality is very bad - massive compression blockyness in dark areas.  I have photos.

I've looked at the exact same scene streamed to a Chromecast (Yay! Prime can Chromecast at last) and there is a noticeable difference, so the source files at the Amazon servers aren't to blame.

Is there some setting somewhere that will convince the Amazon servers to serve a better quality to my Roku box.

Box is connected via wired cable - Chromecast was Wireless - so I'd thought that the Chromecast would be worse!

Any Ideas?

What if you try the Roku wirelessly? Maybe there's a problem with your wired connection. Also, what resolution nos your Roku set to?
Yeah, I got some Rokus.

Thanks

I just tried Wireless - same result

Roku was set to Auto for screen type, I changed it to 1080p but no difference

And your Chromecast is plugged into the same TV? Have you tried it in the same port to make sure it isn't a port specific setting on the tv?

Other than that, I don't know why you'd get a much better picture with your Chromecast.. I think my Fire Stick has a SLIGHTLY better picture on some channels, but not vastly better.
Yeah, I got some Rokus.

Yep , everything into same TV - the Roku goes via a Denon amp, but that is HDMI pass through - no processing - but I will try direct connection

Re: Roku 2 (4205) Poor Amazon Prime quality

The Chromecast/Roku PQ could be an apples-to-oranges comparison. The reason is that there's most likely different streams from different content delivery networks dedicated to each service.  In other words, the Roku Amazon channel might be hitting a different content delivery network and stream than the Chromecast, and there may be issues between you and the delivery point of the content delivery network. 

I don't have any issues with Amazon Prime video at my home on my Roku. In addition to what jeffrok suggested, you could try setting a different DNS server in your router, like OpenDNS or Google's DNS, vs. whatever your ISP's DNS is.  You may end up with a different (and better) path to the Amazon Roku stream this way. Worth a shot - takes but a couple of minutes and a router reboot.

Google DNS

Preferred: 8.8.8.8
Alternate: 8.8.4.4

OpenDNS

Preferred: 208.67.222.222
Alternate: 208.67.220.220

And the same is true in reverse - if you already have your DNS set for one of these, try reverting (as a test) to your ISP's DNS.

OK - I'll try tweaking router DNS - I use OpenDNS at the moment - hopefully that wouldn't make any difference as it will mess up everything in the house - I use OpenDNS as a first line protection against various sites.

I'll let you know................

Nope changing DNS to default UK ISP DNS didn't do anything Smiley Sad

Ok, another question.. is Amazon prime natively supported in UK, or are you using a VPN of some sort?
Yeah, I got some Rokus.
