Lag on HDMI HD lcd screen
I'm a long time Recalbox user. I have now a GBPi3 which is perfectly running excepting the screen that has some lag on menu and games (not video)
Here we see it on the "rainbows" on the menu
And there when lightnings (3 obliques lines)
Can anyone help ?
I found this, would it be usefull ? https://github.com/recalbox/recalbox-os/wiki/TFT5-Screen-HDMI-(EN)
@pegoncology can you tell which screen you have ?
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
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
uncomment to force a specific HDMI mode (this will force VGA)
comment to get jack audio
Using /etc/modules is deprecated and no longer supported on 4.4 kernel
So manually enable audio
force hdmi while the tv can take time before sending the signal on the hdmi output
uncomment for composite PAL
uncomment for 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
uncomment if you don't want the rainbow at startup
@pegoncology can you get the supported HDMI modes using tvservice ?
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. #

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

@pegoncology Can you enable DrwFPS and make sure all runs at 60FPS ?
I have to put this :
bool name="DrawFramerate" value="false" to "true" into es_settings.cfg ?
@pegoncology no, you can do it from the ES menu, in advanced settings i think
It is well running at 60fps but I didn't find DrwFPS into ES menu
@pegoncology paramètres avancés > afficher le framerate
pan pan q q !
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
@pegoncology it's not stable on more powerful boards, don't worry
now for your screen ... too bad, i'd say :/
The builder told me we should wait for firmware update but indeed too bad...
