I'm using version 0.3.5 and a raspberry pi zero W. When i plug in my laptop to the display via HDMI the content is scaled to full screen. In the difference to Issue #43
I've got black bars at all sides.

I've tried different things but at the end
disable_overscan=1 solved my problem partialy
I've executed tvservice -s and got
state 0xa [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive which correlates to the Displaytype.
Also fbset -s promts
`mode "1920x1080"
geometry 1920 1080 1920 1080 32
timings 0 0 0 0 0 0 0
rgba 8/16,8/8,8/0,8/24
endmode'
but some pictures have a much less quality than when i view them on the webdav Server with an other device.

@HirschJunge Can you provide some photos taken from the screen? I'm not sure what issue you are experiencing.
Regarding quality: fbv (Frame Buffer View) does a very simple scaling ( e.g. no low pass filtering). This results some times in artifacts.

I'm going to add

disable_overscan=1

per default.

@avanc unfortunatly the screen is now hanging by my grandparents. I will take some pictures the next time I'm around.

@avanc avanc added this to the 0.4.0 milestone Jan 15, 2022

I also see this with the current release, adding disable_overscan=1 fixes it.

Also the log messages are not in the corner of the screen but shifted inwards so its easily distinguishable from wrong image viewer behaviour/settings.
