@greenalex said in Recalbox 8 - Problème d'affichage sur Sony PVM via adaptateur HDMI/VGA:

ps hier soir, donc j'ai juste lancé un test, à savoir configuré comme dans mon message précédent. Résultat : écran noir, et le Pi avait la led verte qui clignotait par série de 7 ( à priori, un problème d'affichage...).
Tu as donc laissé les les videomode de recalbox.conf sur leurs valeurs par défaut ?
Et tu as modifié le config.txt, ou le recalbox-user-config.txt ?
Tu peux me dire exactement ta config (idéalement la copie de ton cmdline.txt et de ton config.txt), histoire de ne pas perdre trop de temps à re-tester les même choses ?
Merci, à plus !

Des que je rentre ce soir je mettrais ça ici! C'est pas encore optimal, je dois encore réglé tout ça mais au moins tu as une image stable, net et ça déborde pas trop.
Franchement pas cool de la part de Recalbox de nous faire galérer, et je remercierais jamais assez @davidb2111 pour l'astuce du cmdline.txt alors qu'avec les autres distribution j'avais direct une image sur mon PVM après avoir changer la résolution!

@amirking said in Settings on monitor Sony PVM 14M2U CRT!!!!:

Hello,
I can't find the right setting with my Sony PVM 14M2U monitor.
I have tried various configurations, but the screen is never aligned correctly.

Currently used:

Raspberry Pi 3b
Recalbox 18.07.13
Gert-VGA VGA666 Adapter Board
VGA Male to BNC Male Adapter (5 BNC. 3 RGB + 2 sync H / V)
This is the configuration in the "config.txt" file:

disable_splash=1
disable_overscan=1
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512
avoid_safe_mode=1
kernel=zImage
overscan_scale=0
disable_audio_dither=1
dtparam=audio=on
dtoverlay=vga666
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1
hdmi_group=2
hdmi_mode=87
I believe that the problem is of the "hdmi_timings" line, in fact even with other values taken from the web, I always get unsatisfactory results. But isn't there any way to put the correct values based on my monitor?

There is no "perfect" setting as they all need to be adjusted on a case by case basis depending on what the monitor needs. So in short, someone elses values could completely screw you up if they varied drastically from your original values.

Can anyone help me?

Hello !
For the globalvideomode, i think it's already on defaut, which is fine.
it will use whatever resolution you have forced in the config.txt, in this case DMT 87, the custom resolution you choose above.

in the case you want to be more clear in the config :

global.videomode=DMT 87 HDMI system.es.videomode=CEA 6 HDMI

(because emulationstation will be too small in 320 240, you need 640 x 480 interlaced)

for the resolution i dont use 320 x 240, but 1920 x 240, (1920 can fit a lot more emulator with original resolution.)

this is my config.txt :

hdmi_cvt=1920 240 60 1 1 0 0
hdmi_ignore_edid=0xa5000080
hdmi_pixel_encoding=2
avoid_safe_mode=1
disable_overscan=0
config_hdmi_boost=4
hdmi_drive=2
hdmi_group=1
hdmi_mode=6
hdmi_force=1

kernel=zImage

After that, you have to create a config file in the retroarch folder, like this for each emulator :

nes.cfg
aspect_ratio_index = "22"
custom_viewport_width = "1792"
custom_viewport_height = "240"
custom_viewport_x = "63"
custom_viewport_y = "16"

which define the exact viewport for the emulator.

Sorry for my english, tell me if you need more info 😉
