15Khz hdmi-vga-euroconector on attract mode
« on: March 15, 2018, 05:34:15 AM »
Hello.
I`m trying to show image on my tv with the raspberry pi.
I got a hdmi/vga converter, and a vga-euroconector cable with 5 volts powered via molex (this cable it´s already tested on winmodelines and works fine)

I tried all tutorials on internet about 15 khz on the retropie, but nothing seems to work on my device.

My config.txt (/boot) it´s this, but i tried so many changes on it and nothing changes the image i see on the tv (colour points and no sync).

Code: [Select]
# 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

# ignore edid advice from monitor as we're hardcoding our settings
hdmi_ignore_edid=0xa5000080

# set the pixel encoding to '2': RGB full (0-255)
hdmi_pixel_encoding=2

# 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_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=8

# this is how to set and use a completely custom mode
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87

# use this to set framebuffer color depth
#FRAMEBUFFER_DEPTH=32
#FRAMEBUFFER_IGNORE_ALPHA=0

# disable the rainbow splash screen on boot
DISABLE_SPLASH=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# 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

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

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
overscan_scale=1

I tried, for example, other lines for pal like this one
hdmi_cvt=336 249 60 1 0 0 0

I tried everything but always the same image on the tv, a colour points (you can imagine it´s the splash screen but only for the colours of this points).
Can anybody help me?
