Getting the MagicMirror full-screen resolution

petrpls

Hi!

Total noob here, trying to set up the interface for MagicMirror. So far everything has been pretty straightforward, except for one problem:

The resolution doesn’t really go full-size. Check out this Image:

Its fit correctly to the left and bottom size, but top and right are not being used. I set the MM css to white background to demonstrate what it looks like in the picture

I’ve been playing around with boot/config and trying different overscan options, and disabling overscan but i’m not really sure this is the issue at all… ?

The monitor is an LG W2040s and according to the TVService the preferred hdmi mode was 83 (which im running in the boot/config)

The monitor is running VGA to HDMI (Via adapter), and i had to force HDMI to boost 11 to remove some flickering (monitor turning on and off after a while) as well…

Any help appreciated!

Best regards,
Peter

You need to edit your config file ( /boot/config.txt) see this thread for details.

@pjkoeleman I saw that forum post a while back, and tried both manually overscaning to get the black board out, and also running disable_overscan 1 but it still ends up the same. This is my current boot/config

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=10
#overscan_right=-1000
#overscan_top=-512
#overscan_bottom=-256

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=83

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=1

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
config_hdmi_boost=11

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
display_rotate=1
avoid_warnings=1

Any thoughts on what could be missing?

Does your monitor itself allow adjustment?

have u tried sudo raspi-config ?
Go to advanced and then to resolution.

There’s just one option for “resolution” on the physical monitor settings, and that is to move the “frame”. i.e i can make the white drawed surface move around, but i can’t reduce the black frame… :(

I tried but it didnt make a difference… i guess its like setting the mode and stuff in the boot/config but through the interface instead ? :|

Otherwise first connect directly via HDMI and see what kind of image this gives.
