Display sizing on Raspberry Pi 3
Closed this issue · 1 comments
Following your comment on Screenly OSE issue #527 (Screenly/Anthias#527) I installed and setup electric-webview myself on a test raspberry pi.
After getting everything complied, the browser works, however, the display size is completely wrong. When starting up, the app says:
"Unable to query physical screen size, defaulting to 100 dpi"
I tried setting the values as follows but it didn't help - the error goes away but the display is still broken:
export QT_QPA_EGLFS_WIDTH=1920
export QT_QPA_EGLFS_HEIGHT=1080
export QT_QPA_EGLFS_PHYSICAL_WIDTH=177
export QT_QPA_EGLFS_PHYSICAL_HEIGHT=100
export QT_QPA_EGLFS_DEPTH=24
export QT_QPA_EGLFS_ALWAYS_SET_MODE=1
For example, when I follow your example and try to load github.com, I only see github on about 1/5 of the screen even though I put electric-webview into full screen mode.
Any suggestions on how to get this working properly on a Raspberry pi? Any advice would be greatly appreciated.
I had a similar issue on some monitor models and found a workaround following these instructions:
