    Title HDMI resolution or aspect ratio configuration
    Device OnePlus8Pro Software Version O2 Stable 200411
    Topic Suggestion
    Feature Needed Background Description Connecting to a 1920×1080 TV results in a 1920×873 output with black bars on the top and bottom. Watching/playing 16:9 content on it then results in a 1552×873 video with black bars on all 4 sides. This makes it so that the video output feature is basically useless, despite working quite well (and with a lot less input lag than my previous phone, for example).
    Any other comments
    When connected to an external display with a USB-C to HDMI adapter, we should be able to change the output resolution, or, at the very least, the aspect ratio (I would be okay with having a 2560×1440 output downscaled to 1920×1080, for example).

    I believe this will never gain much traction from a forum perspective, since it's a niche concern that most users will never have. However, it's probably an easy fix (LG did it, for example, in the Android 10 update for the LG G7 ThinQ, and I assume recent flagships as well), so, is there any way to bring it to the attention of the developer team other than begging for likes/replies?

    I have not tried this, but it may work: Try Settings / Display / Advanced / Resolution / FHD+

    That makes absolutely no difference, since the aspect ratio is the same. It just downscales from 2376×1080 to 1920×873 instead of doing so from 3168×1440. Said picture is then letterboxed to 1920×1080, producing a terrible result for media consumption. It would have to be an aspect ratio toggle, like LG has for their phones when connected to an external display. That would change resolution to 2560×1440, which would then be downscaled to 1920×1080 with no black bars, filling the TV. If running the phone in FHD+, it would change from 2376×1080 to 1920×1080, which would then go through without any scaling needed.

    I'm bumping this for attention. It's been almost a year, I'm now using a 9 Pro (the original 8 Pro from this thread is my dad's), and this very simple fix is still not implemented. Is there any way to bring this to the dev team's attention?

    my bump is my 9 pro seems to be showing a lower resolution... like really grainy low..

    can't find setting to get it to increase HDMI Rez output ...

    my p30 pro is sharp and clear and seems to be at 1080p

    hey... so I have great success connecting huawie to tv...

    I use a USB to HDMI converter. there are many.

    but since the phone won't negotiate the resolution the output is low Rez.. it's watchable but text looks bad

    one unit is unpowered so cannot charge phone but it's small
    the other has a USB power input and output so it will charge the phone... however the picture will not show until I disconnect and reconnect the power (another bug because the huawie does not require this)


    now on my Hisense tv I had to turn off hdmi 1.4 detect (I just got phone update so maybe that was fixed) and lock it on 2.0 hdmi

    when I use either of the above devices on a 2k monitor the image is in high Rez... but on 4k tvs they are low Rez.

    when I use an HDMI capture card with these devices I get high Rez on the tv but the audio is not there and playing a movie keeps stopping every 10 to 15 second
