Hello,

I have installed RecalBox 8.1.1 electron on my RPi3 B+ and is running fine on my PC monitor, but when i switch to a new monitor, Lenovo L22e-20, it does not boot (i can not ping its ip).

so, i did the following i had connect it to my old pc monitor, HP Z24i, and it boots and runs ok then i disconnect the hdmi from my old monitor to the new one and i am still getting the main screen but if i starts a game goes off.

Also if i switch off or restart the Recalbox it does not boot on the new monitor

PSU 5V3A

Thanks in advance

I see this file recalbox-user-config

with those , I changed hdmi_group and hdmi_mode but i can not find global.videomode=

# Change to your needs

# 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=16

# Sound output. Set to 0 or comment for autodetect, 1 for DVI, 2 to force HDMI.
#hdmi_drive=2

config_hdmi_boost=0

# uncomment for composite PAL
#sdtv_mode=2

# uncomment for lirc-rpi

So RecalBox starts but shows no Picture ?

Yes, it starts, the monitor detect the input (monitor LED goes White), i do not see any picture or logo and then the monitor goes Sleep Mode.
