Fire TV Cube gains Improved Upscaling as well as DTS, DTS-HD, and Dolby True HD audio passthrough in latest software update

Amazon is pushing a new software update to the 3rd-gen Fire TV Cube that should make video and audiophiles happy. Software version (PS7613/3686) is currently rolling out to devices with improvements to the Super Resolution Upscaling feature that should make non-4K content look even sharper. The update is also adding a feature that has long been requested by surround sound enthusiasts, which is support for DTS, DTS-HD, and Dolby True HD audio passthrough.

Super Resolution Upscaling is a feature that is unique to the 3rd-gen Fire TV Cube and is Amazon’s answer to Nvidia’s AI Upscaling feature on the latest Shield TV and Shield TV Pro. Both upscaling features are supposed to go beyond standard upscaling to make lower-resolution video look even better on 4K TVs. While Nvidia’s advanced upscaling results in a noticeable change compared to standard upscaling, the Fire TV Cube’s advanced upscaling seemed to make little to no difference. This latest software update is supposed to improve things. Stay tuned for an upcoming article from me comparing the Cube’s new upscaling to the Shield TV and detailing whether or not the update has made a difference.

In addition to upscaling improvements, as mentioned, Amazon has added support for DTS, DTS-HD, and Dolby True HD audio passthrough. Support for these lossless surround sound formats has long been missing from Fire TV devices. Fire TV devices have supported several Dolby formats with onboard decoding for a long time, but these more advanced formats have been missing. That finally changes with the latest software update currently rolling out. You won’t find any new audio settings to enable or disable, but the aforementioned audio formats should be passed through automatically when used.

Amazon has confirmed to me that both of these new video and audio improvements are included in the version (PS7613/3686) software update that is currently rolling out to devices. Amazon says the update should be available to all 3rd-gen Fire TV Cube owners by the end of the week. I’m unsure if other Fire TV models will also receive support for the new audio passthrough formats. I’ve asked Amazon for clarification and will update this article if I receive a response.

    Do you know if Dolby true HD includes Dolby true Dolby Atmos HD.
    And do you Know if The 4K Firestick will get update as well as the max and Cube 3.

    Looking forward to seeing a comparison between the new cube and the Shields upscaling. Thank you for keeping us updated Elias.

  3. Mark says: is the update my Fire TV TV’s got. Seems to be the same update?

    How about Mirroring without an app

  5. Kir says:

    for me, the main thing is that Amazon has finally added
    support for NTFS drives ! [even the Fire TV Cube 2 has
    MUCH BETTER picture quality than any Stick Fire TV ]

    but for 3 years I have been asking to add support for all
    languages, as is done in the normal Android OS and iOS

      I like to get the Cube 3 and compare it to the 4k firestick for picture quality. As I have my firestick connected in the hdmi port on my receiver and it always displays the picture in Dolby Vision. Sometimes it is not or not only about the streaming device but how your TV setup and picture settings in the TV Menu. Unfortunately at this time to get the Cube 3 to my County it is About 500.00. But I like to get one and see how it performs. Not just the sounds and picture quality. But overall performance. Unfortunately one thing is you still can’t get Dolby Atmos music from the Amazon music app. That one thing you can get apple Dolby Atmos music on there New Devices.

        “5 TV settings that HARM picture quality !”

        “How to make any TV show BETTER – 6 settings”

          Xbox, satellite box etc connect all fine.

        • Oz says:

          If your device always displays Dolby Vision I think it is because you have “always HDR” in Display settings selected. If you change to “Adaptive” it will recognise and adapt to the stream being watched.

    • Edz says:

      Im confused does the cube not already output dolby true hd and atmos? I get that through all apps… Does this mean for certain apps?

      • pawdog says:

        No it doesn’t. It already supports Dolby Digital plus Atmos from streaming services. True HD comes from disc rips for playback with Plex, Emby, Kodi and similar apps.

  6. Mark says:

    Honestly, how much better could it possibly be over the 2nd gen cube?

    • Mark says:

      I mean the PQ…

      • nvidiashieldguy says:

        Well considering the Shields upscaling is miles and miles better picture than the gen 2 cube, I’d imagine any upscaling the 3rd cube is doing is going to be miles better than the non existent upscaling the 2nd cube does.

  7. dave durlin (papa dave) says:

    This improvement is part of update (PS7613/3686). Is there a way to get this improvement if I am running FOS (PS7613/3675), and I am using ADB Clear Software OTA command to prevent auto updates. Thanks for your help.

  8. EQP says:

    Will they be adding more ads? Cause I don’t feel like they’ve quite taken hardware I paid for and used it to incessantly try to sell me shit quite enough.

  9. William Gibson says:

    Are there any department stores that carry the new u]dated fire TV cube in N.H?

  10. Rick says:

    The fire tv cube gen 2 supports 16bit/192khz audio. Does the gen 3 support higher resolution?
