The display does not work I2C help!

Hi guys, could use some help…
I have a raspberry with PIFI DAC + 2.0 and I have a 1.9 oled that works perfectly model:
0.96 pollici OLED SSD1306 bianco/blu/giallo 128X64 IIC I2C modulo Display seriale 12864 scheda schermo LCD per Arduino|display module|oled module128x64 oled - AliExpress 5.0&scm-url=1007.13339.291025.0&pvid=da7789f6-1b41 -4e35-b7ee-3cf7a8a3fb5d&_t=gps-id%3ApcDetailBottomMoreThisSeller%2Cscm-url%3A1007.13339.291025.0%2Cpvid%3Ada7789f6-1b41-4e35-b7ee-3cf7a8a3fb5d%2Ctpp_buckets% 3A668%232846%238111%231996&pdp_npi=3%40dis%21EUR %211.65%211.53%21%21%21%21%21%40211b5e2416846206734308772e872c%2112000025686777041%21rec%21IT%21725564962&gatewayAdapt=glo2ita

and everything works great, since this display is small
I wanted to replace it with this:
Modulo Display LCD OLED da 2.4 "2.42 pollici 128x64 SSD1309 12864 interfaccia seriale IIC I2C a 4 Pin per Arduino UNO R3 C51| | - AliExpress 44b2-8b7e-d63aa0d9eebd-15&pdp_npi=3 %40dis%21EUR%2113.25%2110.73%21%21%21%21%21%40214527c616846206622901113d0723%2112000032330939225%21sea%21IT%21725564962&curPageLogUid=1Mf 4OVHlTLSp

the model I have is 4 pin, I connected it but it doesn’t turn on, the connection diagram is:

I respected the connection types on both displays, but the small one works, it’s the 2.4 one, no, I need some help.

I installed the native mpd_oled plugin from volumio , with the small display it works (the one from 2.4 doesn’t work)

i also completely uninstalled native mpd_oled this is installed:

but it still won’t turn on or display anything…
I post the photos in ssh

There are 2 diodes on the board. D1 and D2. They need to be closed.

meanwhile thank you very much…
you are great…

the display is on it works, but the display refresh is very slow when I snap between one song and another the display is still the song does not change in real time also the non-spectrum bars do not move

This is not a display problem. This is a plugin problem and I do not know the correct answer. Try to chat in the plugin topic.
https://community.volumio.com/t/plugin-mpd-oled-installation-configuration-plugin/44823

I installed the plugin manually. Its settings are not in the list of plugins. Try to run the configuration via ssh:

sudo mpd_oled_service_edit -o 6 -a 3c -b 16 -g 1 -f 40

could you write me the procedure for manual installation…
