At my Wits end! Overscan/Underscan. Nothing changes

sdetweil

is this the pi desktop that is too big, or the MagicMirror UI ?

JonoGee

@sdetweil It is the Pi desktop that is too big mate. but equally makes the MM too big too when launched.

sdetweil

@JonoGee ok… don’t have a solution myself, just trying to help others get clear idea of problem… I searched and all the things I saw are the same as what you have done

See these URLs for details, if not known already:

Can you try this ?

$ tvservice -m CEA
$ tvservice -m DMT

This will give you the hdmi_group that can be used and the preferred hdmi_mode.

hdmi_group=1
hdmi_mode=16

This means CEA 1080p @60Hz.

And what happens when you comment out disable_overscan and the overscan settings ?

@evroom
Hi buddy,
I tried disabling out all overscan settings etc. It didn’t make the slightest change, neither did…

hdmi_group=1
hdmi_mode=16

I am not sure where i should be putting…

$ tvservice -m CEA
$ tvservice -m DMT

I checked out those links and nothing I do at all makes any change whatsoever. I see no adjustment or anything. I’d be happy if i did then i could keep adjusting, rebooting, and re-adjust accordingly until it was right.

THankyou for your time anyway trying to help me sort this. I really appreciate it.

They are not config entries.
Just execute those commands from the command-line.

The config file entries in your first post, are they yours or just an example ?

Let’s start with the tvservice commands.
Please post the output, then we take it from there.

$ tvservice -m CEA
$ tvservice -m DMT
$ tvservice -s

Not an expert on the topic, but who knows we straighten this out together :-)

Sometimes you can fix/set overscan in the menu of the monitor, may be this helps?

JonoGee

@cirdan It was displaying fine with a black border actually during the Raspi setup and I ticked something during setup and its been like this since.

JonoGee

Any other device, PC, DVD Player, PS4, what ever i plug it its fine. Raspi homepage. spilling outside screen area.

Did you ever touch the /boot/config.txtfile ?
Or only did the config using $ sudo raspi-config or via the GUI ?
It can be you selected Overscan there.

Can you also show the output of this command ?

$ cat /boot/config.txt | grep -v '^#' | egrep 'overscan|framebuffer|hdmi|dtoverlay'
