Black screen using HDMI2VGA

@xphere I don't know, but @ian57 probably does!

@xphere not even noobs displays anything ?

[xphere]

I've tried all possible options and none seems to work... Even noobs is not displaying anything...

it's strange because I've seen on forums and youtube videos that my adapter works on rpi! but none of the options worked for me.

hi, here is my config for 240p on my crt with hdmi => vga :

hdmi_ignore_edid=0xa5000080
hdmi_pixel_encoding=2
avoid_safe_mode=1
disable_overscan=1
config_hdmi_boost=4
hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=1
hdmi_mode=6
hdmi_force=1
kernel=zImage
hdmi_force_hotplug=1
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512
avoid_safe_mode=1
disable_splash=1
dtparam=audio=on

@idarius thanks for the reply! I will try that configuration! eventhough, it sounds strange to me that you have tried the CEA mode:

# this is for HDMI_CEA_480i60
hdmi_group=1
hdmi_mode=6

If you are using a VGA monitor, should not be better to use a DMT mode?

# this is for HDMI_DMT_VGA_60 (640x480)
hdmi_group=2
hdmi_mode=4

@idarius by the way... what does this parameter in your config do?

hdmi_force=1

I've not found any documentation related, probably you mean "hdmi_force_hotplug=1"? (you already have this parameter repeated twice in your config)

Thanks!

yeah i think it's a mistake for the hdmi force 1, i seen it on some forum.
For the hdmi mode 6 group 1, its because on a crt i need 480 i. talked about crt tv, not crt pc screen, so resolution is 240p max or 480interlaced.
my games run in 240p (320 x 240), but EmulationStation is unreadable with this resolution, so ==> 480i

@idarius Thanks for the explanation.
I've tried your code but... no luck! I'm always getting no signal on my TFT (LG 19inch L1953S-SF).

[xphere]

I have found the solution!!!!!!!!!!!!!!!!
The problem was not in the converter, neither in the configuration!
The problem was due to this!!! the fu**ing hdmi wall mount that I have in the box that contains the rpi was cutting the VGA signal, so I tried to connect the HDMI2VGA adapter directly to the rpi, instead of the wall mount and... voilá! works perfectly!!!! even detects automatically the resolution!!!!

so.. conclusion: DO NOT USE ANY CABLE BETWEEN THE HDMI OUTPUT AND THE HDMI2VGA CONVERTER!!!!!!

hehe cool for you, pretty weird
