Hello,

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

https://www.amazon.fr/gp/product/B01ARLD1HU/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

and another cable VGA to BNC

https://www.amazon.fr/gp/product/B0033AF5Y0/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

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:

https://www.retrorgb.com/rpi240p.html

disable_overscan=1
hdmi_ignore_edid=0xa5000080
hdmi_pixel_encoding=2
hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
DISABLE_SPLASH=1
config_hdmi_boost=4
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256

Do you have any idea?
