Hi Zdenek,
I just installed the Netatmo-Module, but I can’t get the “refresh_token” vial Hurl-it.
I always get an “400 Bad Request”.

Where ist the trick?

Maybe it’s because I don’t know what the “gant_type” “password” is supposed to be?

Thank you for your help.

Man, I could freak out: The HDMI to DVI cable is somehow broken. I replaced it and everything works fine again. I spent hours to solve the problem… F**K!

Now I tried this, as mentioned here

hdmi_cvt=1920 1200 60 5 0 0 1

Nothing happened: The Raspi stucks on 640x480…

tvservice -d edid
Nothing written!

I tried this before…
edid seems not to work.

/opt/vc/bin/tvservice -m CEA
Group CEA has 2 modes:
           mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive 
           mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive 

/opt/vc/bin/tvservice -m DMT
Group DMT has 1 modes:
  (prefer) mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive 

The Mirror worked for mont without any issues…

/opt/vc/bin/tvservice -s
state 0x120006 [DVI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive

That is the resolution shown by the Raspi.

Slowly I have the feeling like sitting at an Windows-Machine…

So, here ist my /boot/config.txt:

# For more options and information see
# http://www.raspberrypi.org/documentation/configuration/config-txt.md
# Some settings may impact device functionality. See link above for details

# 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=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_heiframebuffer_width=1080
#framebuffer_height=1920
#framebuffer_depth=32
#framebuffer_ignore_alpha=1

# 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=2
hdmi_mode=69

# 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=4

# 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

The Samsung Syncmaster 245plus has a native resolution of 1920x1200@60Hz.
I think the hdmi_group an _mode settings are correct, but it still doesn’t work…
What is wrong?

No, unfortunately the Monitor was turned on. I think there is sth wrong with the settings in /boot/config.txt
But I can’t figure out, how to fix this.

Hi there,
my MagicMirror worked fine, until I had to rebbot the Pi for some reason.
After rebooting the resolution is far too low. I use a Samsung Syncmaster 245B+ with FullHD.

How can I fix this?

Cheers
