    I have a serious problem and i don’t understand the reason.. please i need help urgently..

    I have a new screen ACER K222HQL connected via HDMI
    BUT, Emulasion Station “flash” on the menu, impossible to understand the reason

    i have :
    Change Raspberry –> No
    Change Cable HDMI –> No
    Change cable HDMI to DVI –> No
    Put the raspberry on a old DVI Screen –> Perfect ! O_O

    Look the video for a good understanding : https://www.youtube.com/watch?v=4ewWnrVHuTw

    I need to finish this arcade cabinet for 7 day, is not possible to me to rebuy a new screen or change, the problem are on the software

    hi, thank you for the reply.

    I know this solution but i have found the best solution.

    For this moment my /boot/config.txt is :

    hdmi_save=1
    hdmi_drive=2
    hdmi_group=1
    hdmi_mode=16
    config_hdmi_boost=7

    but i running only on 640*480 now :/

    i need to 720p or 1080p

    Change: gpu_mem=64

    to: gpu_mem=256

    Or 128 if you have model A

    Remove these:
    config_hdmi_boost=7
    hdmi-_safe=1

    You might want to overclock the Pi as well, mine runs stable at 1000mhz, it helps with some emulators. There’s an overclock thread in the forum for reference.
