    Variable Refresh Rate (VRR) & Auto Low Latency Mode (ALLM) Bug


    The below are not my words. They are someone elses writeup of a test they did. I am also having the same issue. Can we get someone on the Xbox Team to open a support ticket to the engineering team so we can get this huge inconvience resolved please?

    ____________________

    Over the course of the past month, I've been playing around with the Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) options on my Xbox One X (X1X) as displayed on my LG C9 OLED. I've discovered a bug with how the two features interact (as I will outline below) and through additional research, I believe the bug is on the X1X side. I hope this long post helps somebody...anybody.

    Note: On the C9, other than a popup notification that appears when ALLM engages, there is no visible indicator in any menu that the TV is in ALLM. The easiest way to tell if the C9 is in ALLM is to set the picture to Cinema mode and then select Picture Options. If Noise Reduction and Smooth Gradiation are "grayed out" (i.e. unselectable), the TV is in ALLM. Other manufacturers may have indicators and/or different ways of confirming the mode is engaged. A menu indicator for LG would be fantastic.

    When I first setup the TV and connected my X1X, I immediately turned on the ALLM functionality on the TV and selected the checkboxes for "Allow auto low-latency mode" and "Allow variable refresh rate" on the X1X. I quickly noticed that in addition to the desired effect of engaging ALLM while gaming, the TV seemed to stay in ALLM mode no matter what I was doing. On the dashboard, using the X1X Netflix

    App, using the X1X YouTube App, watching cable through my X1X...it was always engaging the low latency mode. The only time I noticed ALLM disengaging was when watching a BluRay or UHD BluRay through the X1X disc player (this is still the only circumstance where I can find the TV disengaging the ALLM when VRR is active).

    I posted this concern on the rtings.com discussion boards and Adam Babcock responded with: "Do you have the variable refresh rate feature enabled on the Xbox? It appears that this forces the TV into game mode at all times, even if you aren’t in a game." https://www.rtings.com/tv/discussion...-actually-work

    Adam is great, but because I'm a "trust, but verify" type of guy, I went in and unchecked "Allow variable refresh rate" on my X1X and redid my checks. Sure enough, as he suggested, the X1X immediately started behaving differently. The ALLM would only engage when I booted up a game from the dashboard. In all of the other X1X streaming video apps, and while hanging out on the dashboard, ALLM would not kick-in. In other words, once I turned off VRR, the ALLM behaved like I though It should.

    But what if I was wrong? What if, despite being counter-intuitive, VRR was supposed to engage ALLM at all times except for disc-based video content on the X1X? Nope, according to HDMI.org, my understanding of ALLM and how it is supposed to work with VRR is correct : "Your gaming box will take care of these choices for you. If you are streaming video or playing a BluRay, it would only enable QMS; if you fire up a game, it would enable ALLM, VRR, and QFT, depending on what your system supports." (emphasis added) https://www.hdmi.org/manufacturer/hdmi_2_1/index.aspx

    Now, knowing that the way VRR and ALLM were interacting was not according to specification in my setup, it was clearly a bug and not a feature. The question remaining was, is it a problem with the X1X or my LG C9 OLED? I'm still not 100% certain, but I'm growing increasingly convinced that the problem is with the X1X. I've found numerous comments on Reddit where people with different TV sizes and/or manufacturers report encountering this same problem. See a few examples below:




    I'm going to do my best to try to get this to the attention of Microsoft, but in the interim, the most practical solution I've found is to turn off VRR on the X1X but keep ALLM active. This way, ALLM behaves properly and I can just turn on VRR when playing the limited games on the system that support it.

    Please let me know if you've encountered anything differently with your setup or TV.

    TL; DR - ALLM and VRR do not function properly when passed from the X1X. When VRR is on, it forces all content (except disc-based video) in to ALLM. When VRR is off, ALLM functions properly (i.e. only engages during gaming). This appears to be a bug in the way that the X1X is sending the ALLM and VRR flags to the TV.

    XBox one Starts up in 640 x 480 wide screen mode and not 4k, second question is about start up name

    Hello,

    Try this fix: https://support.xbox.com/en-us/xbox-one/console/adjust-display-settings

    Very important things:

    Video modes

    Video modes let apps and games override system display settings to allow passthrough of the following video content types:

    Allow 50Hz

    This setting allows your Xbox One to render a 50Hz signal if the video source is encoded for 50Hz. This is a standard refresh rate in Europe, the Middle East, and Africa, and many places in Asia.

    Allow 24Hz

    This setting allows you to view your movies in 24Hz refresh rate, which is the natural frame rate for movie viewing.

    Allow auto low-latency mode

    Auto low-latency mode (also known as “game mode”) lets the console tell the display to change latency modes when a game is launched, and then revert after you quit a game.

    Note Low-latency mode is achieved by the TV disabling its processing features that would otherwise introduce latency. Disabling these processing features may affect picture quality—HDR colors can appear washed out,
    and contrast and backlighting can appear off because of the trade-off for low latency. Turn off this feature if you don’t like the picture quality.

    Allow variable refresh rate

    Variable refresh rate (VRR) technologies are used to dynamically adjust the refresh rate of a display on the fly to reduce stuttering and screen tears while playing games. VRR is only available when connected to a TV that supports either
    HDMI-VRR or AMD FreeSync.

    Note With VRR enabled, game clips and broadcasts may appear choppy or show screen tears. This is because the viewer’s playback refresh rate is locked while the active player’s refresh rate fluctuates. VRR may also introduce
    display issues if your video signal is passed through an audio/video receiver (AVR). If you notice display issues you may need to turn off VRR or bypass your AVR and connect your HDMI directly to your display.

    Allow 3D

    This setting lets you watch 3D Blu-ray discs on Xbox One.

    Note Your television must be 3D-capable to watch 3D content.

    Allow YCC 4:2:2

    • If YCC 4:2:2 is disabled and you’re having HDMI video issues, try enabling it.
    • If YCC 4:2:2 is enabled and you’re having HDMI video issues, try disabling it.

    Allow 4K

    This setting allows you to pass native 4K content to your display when available in your games and apps.

    You don't have to set your console resolution to 4K to play 4K content. You can set your console to another resolution, such as 1080p, and when a game or app requires 4K (and your TV supports the 4K mode it wants), it'll automatically
    switch to 4K. This is good if you want to play 1080p content in its native resolution, but also take advantage of the 4K resolution when playing 4K content.

    Allow HDR10

    This setting allows you to display HDR10 content when available in your games and apps.

    HDR stands for High Dynamic Range. With HDR10 on your Xbox One X & Xbox One S, your TV can display deeper colors and richer contrast, meaning the picture will appear more vibrant and realistic than on a regular HDTV.

    Xbox One X no Dolby Atmos using Samsung HW-N950 & Samsung QE65Q9FN 4KTV

    The Xbox is able to recognise the Dolby Atmos capability on the soundbar if connected directly .

    However FreeSync (variable refresh rate ) is not selectable on the display and sound settings page of the Xbox X.

    Free Sync is available on my Samsung Q9 and is an option in the game mode menu of the TV.

    Game mode is a TV mode that allows low latency on Samsung (and other manufacturers) TV's.

    My TV allows Auto Low Latency and this doesn't work when plugged directly into the soundbar (Samsung HW-N950) despite Auto Low -Latency being recognised on the Display & Sound settings page on the Xbox X. The TV will not allow this when the Xbox is plugged
    into the soundbar via HDMI then into the TV by HDMI ARC.

    Auto Game mode or Auto Low Latency turns on game mode while playing games but turns game mode off automatically should i use a blu ray disc for example.

    So two modes made available to me by Xbox and Samsung currently don't work in tandem in the correct manner.

    Why does the Xbox One X force all content (including streaming video) into ALLM if VRR is also selected?

    Freesync is stupid, I never use it. Why would u want to lower your monitor refresh rate? Xbox already has vsync on

    Playing games on a tv always have high input lag

    The C7P has a 120 Hz panel and is able to interpolate lower frame rate content to 120 fps, which significantly improves motion.

    Lmao your tv isnt even real 120hz its 60 interpolate

    https://en.wikipedia.org/wiki/Motion_interpolation

    TV Refresh Rates are fake that why everyone uses monitiors

    I use a MS Optix MAG241C monitor, real refresh and reponse rate and only $200 https://us.msi.com/Monitor/Optix-MAG241C

    https://www.rtings.com/tv/reviews/lg/c7-oledYour tv has a fake refresh rate it double draws the frames, your tv cant fake frames with Auto Low Latency Mode (ALLM) hence turns off interpolation, the xbox isnt
    doing anything your tv is

    Freesync over original Xbox

    Hi there,

    as far as I know it will be depending on the adapter too, most (if not all) will NOT be able to have the console recognize that the monitor will support free-sync. I myself have an adapter and that is Not recognizing the feature at all.

    Regarding which consoles will support freesynch, the testing was limited to the S or X the orginal Xbox One didn't have the option in testing.

    So I'm not entirely sure if it does or doesn't support the feature.

    It doesn't say any limitation type of console for freesync on this page:
    https://support.xbox.com/xbox-one/console/adjust-display-settings


    in this section specifically:

    Allow variable refresh rate

    Variable refresh rate (VRR) technologies are used to dynamically adjust the refresh rate of a display on the fly to reduce stuttering and screen tears while playing games. VRR is only available when connected to a TV that supports either HDMI-VRR or
    AMD FreeSync.


    My assumption is that the cause will be the adapter no matter what console you are using (X, S or original One)

    I hope this will help a bit in the search for information
