@Substring thanks
It is a 3.5 inch hdmi liquid crystal (new model)

@pegoncology can you paste your config.txt ?
Fbcp wouldn't help, it's for spi tft screens

[Pegoncology]

@Substring
Thanks for helping

"HD" games are running smoothly (PS1, DC, PSP), it occurs into ES menus and with SNES and MD for example.

Here is my config.txt

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

disable_overscan=1

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

comment to get jack audio

hdmi_drive=2

Using /etc/modules is deprecated and no longer supported on 4.4 kernel

So manually enable audio

dtparam=audio=on

config_hdmi_boost=0

force hdmi while the tv can take time before sending the signal on the hdmi output

hdmi_force_hotplug=1

uncomment for composite PAL

#sdtv_mode=2

uncomment for lirc-rpi

#dtoverlay=lirc-rpi

if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it

boot_delay=3

uncomment if you don't want the rainbow at startup

disable_splash=1

Overclock

gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=512

avoid_safe_mode=1

kernel=zImage

@pegoncology can you get the supported HDMI modes using tvservice ?

[Pegoncology]

@Substring
I don't understand your question, what do you mean ? (You may tell in French, I posted here to have more advices but I'm French-native too ;-))
I use this image on a GBPi3, it is exactly the same image I use on my Nespi on TV without any problem.
So I assume the problem is with the GBPi3 screen

@Pegoncology you should have post your question in french in the french section. Don't forget that the devel team is mostly french ;)... so the support can ben in french too

anyway, @Substring is asking to run the tvservice command on you Pi to see the detected video mode :

# tvservice -a -s
state 0x12000a [HDMI DMT (35) RGB full 5:4], 1280x1024 @ 60.00Hz, progressive
     PCM supported: Max channels: 2, Max samplerate:  48kHz, Max samplesize 24 bits.

@ian57 @Substring

@pegoncology i'd rather have tvservice -m CEA and tvservice -m DMT

[Pegoncology]

@Substring
tvservice -m CEA =
Group CEA has 15 modes:
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
(prefer) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive

tvservice -m DMT =

@pegoncology Can you enable DrwFPS and make sure all runs at 60FPS ?

[Pegoncology]

@Substring
I have to put this :
bool name="DrawFramerate" value="false" to "true" into es_settings.cfg ?

[Substring]

@pegoncology no, you can do it from the ES menu, in advanced settings i think

[Pegoncology]

@Substring
It is well running at 60fps but I didn't find DrwFPS into ES menu

[Substring]

@pegoncology paramètres avancés > afficher le framerate

pan pan q q !

[Pegoncology]

@Substring
Yes sorry, that's what I did. It shows well 60fps.
But when on ES menu, if I change system and if it is the "first" time I go to the system page, it shows around 40fps then it goes to 60fps in 1 sec. Afterwards I go back to this system and it is well 60fps

[Substring]

@pegoncology it's not stable on more powerful boards, don't worry

now for your screen ... too bad, i'd say

[Pegoncology]

@Substring
The builder told me we should wait for firmware update but indeed too bad...
