Sony PVM 9042QM and raspberry Pi 3

I would like to use my Sony PVM 9042QM with my raspberry Pi3 model B.
Sony PVM 9042QM: https://archive.org/details/sony_PVM-6041QM_9040ME_9042QM_9045QM
I bought this converter HDMI to VGA
and another cable VGA to BNC
I add a T BNC to add video synchro signal
I've connected all things like that:
Raspberry Pi ==> Hdmi ==> VGA ==> to BNC + T ==> to Sony PVM
On my PVM I've the RGB signal in my IN BNC and the T in my Video In entry
When I start recalbox, the menu appear without ptoblem, but when I try to start a game, the display is not correct I've lot of noise
I configured my config.txt file from this site:
hdmi_cvt=320 240 60 1 0 0 0
Do you have any idea?
@danje57 Well, the Rpi3 and video adapters usually give same problem ...
The Tutorial to modify the video in Rpi3 is in this link:
You need to modify the global.videomode in Recalbox.conf, with the value corresponding to your monitor. But as I said, video adapters usually give problem, incompatibility ...
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
After that, you have to create a config file in the retroarch folder, like this for each emulator :
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
