Looking at the config you posted…it looks like you have removed the # signs to uncomment you code?

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

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 ? :|

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… :(

# 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?

Any help appreciated!

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