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

What video mode do you have set in /boot/config.txt

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

for exactly config

Note : the kernel are last updated.

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.
