    the SDR to HDR setting to off is awsome, I did that a long time ago to my airtv mini and all my old stuff looks so much better on my HDR compatible Samsung. On the tivo 4k It does not matter, since the HW acceleration and de-interlacing is broken for mpeg2

    This is more your alley Dan, you are a great programmer, I think you would shine developing for Andriod TV.

    I’m starting to think the same thing. I just got my TS4Ks today finally. After hooking one up and it detecting my Dolby Vision capable display, it shows that it’s on, but when I compare it to my AppleTV forced to Dolby Vision it’s not even close to the quality I get with that. It doesn’t even look like what it’s supposed to being converted to DV. It looks like a horrible rendition of SDR. No wonder you guys don’t like it being forced on. With the AppleTV it’s a completely different story.

    To be perfectly honest, you are my hero as of this moment. The CEC was causing me to pull the 4K from my system.

    Well, though you are still in my mind a hero, unfortunately, turning off CeC on the Stream through the Developer Options disables any sound to be sent via my Samsung TV to my Sonos Beam via the hdmi/arc. Tivo is just going to have to fix their CeC issue before I can have the Stream in my system.

    i remember having to return my first FireTV 4k stick since it wasn't close to ready for prime time. But a couple months later they had fixed many things. Now I own three of the Fire Tv 4K sticks. I hope TiVo doesn't take that long because the price is a promotion. And will go up to $70. With the FireTv Stick 4K I actually paid less when I bought them a few months later.

    My two ATV 4K boxes look just as bad with forced DV or HDR10. Plus it's still way too bright.
    I don't like any device using forced HDR. i was so glad when apple fixed their forced HDr issue. I then bought a second one. But with all my other streaming devices, my ATV 4K boxes are my least used streamers. But then I'm not an Apple person anyway. But some things have only been in HDR or Atmos on the ATv 4K. Which is the reason I first purchased one.

    I found this on Zatz’s site from user HarperVision regarding what appears to be the reasons why this is happening:

    https://zatznotfunny.com/2020-05/tivo-stream-4k-issues/#comment-95552

    ”I’ve found that you need to disable Dolby Vision and make HDR the priority in the Android TV Settings menu and then your colors and picture will look correct, and in my case at least, better than the SDR version.

    They messed up Dolby Vision somehow internally so it doesn’t display properly. It appears that it doesn’t support the Sony version of Dolby Vision, Profile 5 Low Latency Dolby Vision (LLDV). I have confirmed this with an HDFury Vertex2. When I force an EDID that uses LLDV exclusively such as the Sony A1 OLED, I get the dull lifeless image you describe and the Vertex2 reports no Dolby Vision being input, even though the Stream 4K says it’s outputting DV. As soon as I select an EDID that supports the original RGB 8 bit Dolby Vision Version only, the LG C7 OLED, then the Vertex2 reports receiving that signal at its input and the image gets all pink and overblown, which is correct since my display doesn’t support that version of DV and is supposed to appear that way when receiving this type of signal.

    This is the same issue (lack of Sony profile 5/LLDV support) I saw with the TiVo Edge, causing me to return it.”

    I'm building an app that kinda allows you to access all this stuff via the Stream itself and do some other stuff. It will remove the requirement for developer mode and things. I think it's the best way to do this, and can just be downloaded from the Play Store vs having to do all the steps manually.

    I really don’t really understand this compliant with DV/HDR always on. I watched Chris Wallace this morning on my OLED in Dolby Vision and everything seemed to be converted and mapped correctly and the picture looked great. None of the colors or brightness are overblown here. Maybe when it’s only converted to HDR and not Dolby Vision is what your issue is, idk.

    I do agree there should be the choice at least though.

    Any idea how one properly updates a json-like value like that on the commandline with the "settings" command?

    1st thanks so much for sharing this pfcfast2. I've successfully followed your instuctions to use adbLink. However I'm not getting the results I was hoping for. I have an LG 4K TV with Dolby Vision. I've been using YouTube to test. I turned SDR to HDR off but no matter the stream always converts HD stuff to HDR or Dolby Vision. Is this what others are seeing? I tested with the Black Widow trailer which says it's Dolby Vision and that looks good. But I don't want things getting converted as everything I've read says that results in worse picture.

    There is no need to do the any steps manually or even mess around with ADB.

    After seeing your findings (thanks for the initial clues!), I just downloaded an Android shortcut manager like this one. Once installed (need to sideload app), you have to launch it from settings->apps->all apps.

    Scroll down to "Droid Settings" and you will find all the shortcuts you listed on the first post. Unfortunately, you can't pin these shortcuts directly to the home screen on this version of Android (I just get an error when I try from the context menu (long press in Activity Manager)).

    Another problem here is that settings like disabling the broken Dolby Vision (which causes washed out colors / raised blacks even on an SDR TV) revert back to their original value when you power off the TV. Possibly will also happen on any HDMI handshake.

    In its current state, this device is simply unusable to anyone who cares about picture quality. Tivo needs to find more qualified testers and/or developers before they release this type of product in the future. (if any employees are reading this, please send me a private message).

    When I have more time, I will do a more in-depth analysis of the video output using my HDMI analysis hardware similar to what I did many years ago when Tivo broke interlaced output on one of the software updates.

    Edit: Had some time to analyze the video output of this device. See the other thread.

    I can't even find the device setting on this damned thing. I can find the TiVo App settings and GooglePlay settings, but I cannot get it to bring up network settings or other device settings. Never seen such an opaque product in my life.

    Edited to add: Had to shut it off and boot back up to get to the main menu. Only way I could find.

    Yeah —that screen had disappeared and i only had access to the TiVo app and the google apps listing page (press and hold Google App button), not the main page accessed through the remote. When I just that that button, I got nothing but a black screen and sleep mode on the TV (closest thing to turning off before disabling CEC). Had to power cycle to get it back. I’ve turned off CEC now and it’s working much better. Very helpful thread!

    I have that Android shortcut manager on my phone and don't see the app in the play store on the stream. Did you have to sideload?

    I'm guessing they did indeed sideload it, since they linked to APKPure instead of the Play Store link to Activity Launcher.
