Screen settings for HDMI on Linux Embedded



  • Hi all. I'm using a Yocto Linux embedded build on an ARMv7 device. I manage to get a basic QT app compiled and it shows on the HDMI output however the resolution/frame rates are terrible. Could someone advise how I would setup a display profile for a true HD HDMI output for the application. Also it starts up with a green background which can be changed using the -bg switch but this then quickly shows when the app is closed.

    Hi and welcome to devnet,

    You should add which version of Qt you are using as well as board name.
