  • In default configuration, option "automatic mode adjustment" ist enabled and the resolution is set to 1280x720. In your case, the resolution is different, but the detection is not automatic. Was it detected automatically and you then turned it off? Or did you set it manually?

    Why do you need to change the resolution in the first place? It seems to be correct.

  • I need to change resolution because my App is developed already it was working when i was able to change resolution.
    Current resolution is set to 480*800 i need 800 x 1280 pixels or vice versa so please just tell me how to enable change resolution option rest thing i will handle.

  • Sorry, I don't understand. Did you try 800x1280 before? Are you sure your screen supports it?

  • yes i have tried various resolutions it was working i just dont know version was 0.6.3 or 0.6.4 but that custom resolution option was enable so it was working and my application was also tested with diffrent resolutions.

  • i have tested previously when that option was enable and it was working successfully that why i am telling you to just let me know how to enable that option as soon as possible.so i can change and test my application.

  • Please submit a bug report via Settings -> Emteria and I'll take a look into the resolution detection.

  • Bug Report sent to You Please solve it as soon as possible.

  • This information is printed very early during the boot. In your case, it was already overwritten by other output. Please turn off bluetooth (it generates a lot of messages), reboot your device and submit another bug report.

  • bug report sent with BT off and After restart

  • Your screen doesn't support 1280x800 resolution:

  • I see that you have already tried settting it to [800x1280]. Since your screen doesn't support it, it was automatically changed to the best supported resolution, which is 1366x768 in your case.

  • i tried changing using bootconfig and build.prop but tell me how to enable that custom resolution option.
    It not about that screen we are having 7"inch,10"inch and 19"inch HDMI Displays so please i am asking again and again how to enable that custom resolution option or any other way to change resolution.
    I have also sent you another bug report from 7"inch HDMI Display so please check that and provide me solution.

  • It not about that screen

    I don't like the idea of investing my time into analysis of something you actually don't need.

    so please i am asking again and again how to enable that custom resolution option.

    You had the possibility to change it in the RPi settings. Since you chose an unsupported resolution, the system is now blocking you from further inputs. If you want to try it again, you have to do a clean install. In the next OS version, we will allow multiple inputs (as long as the system still boots).

    I have also sent you another bug report

    I did the analysis once and explained you how the system works, so now you are able to do it yourself. If you want more of my time for the same problem, please contact our sales team.

  • ok lets say my screen supports various resolutions like 1280x720 and 1024x768,800x600 currently its set to 1024x768 then Tell me what is ideal process to change screen resolutions.
    is it like 1:Disable Allow Automatic Mode adjustment from Setting->RaspberryPI then Update build.propertied "persist.rpi.mode.backup=1024x768"
    BootConfig to "hdmi_cvt=1024 768 60 6 0 0 0"

    Please confirm Above steps are Perfect to Update Resolution or Not.

    Please read https://help.emteria.com/kb/devices-rpi-3#custom-screen-resolution more carefully. It doesn't say anything about persist.rpi.mode.backup property.

    There is no universal way to change the resolution, but there are two basic approaches:
    1) If the resolution setting is enabled after a clean install, use it. If you enter a non-supported resolution, re-flash and start again.
    2) If the resolution setting is disabled after a clean install, find out why. Probably it is because your screen doesn't support anything else.

    If you know the reasons and you are sure what you are doing, you can edit those files manually.
