My 12.1" screen experience


#1

Had a stack of trouble getting the 12.1" panel to stay on in retro-pie. Eventually hdmi_safe=1 seemed to solve it, so then iterating through the config params that this sets by default it seems that the following two lines magically made it work…

hdmi_group=2
hdmi_mode=4

Which is effectively forcing 720p at 60hz…

Anyone else had any experiences with this screen?


#2

I have the 12.1" screen. Isn’t the native resolution 1024x768 ? The screen provided EDID info seems to be wrong anyway as it started up in the wrong resolution, so on my 12.1" screen I did

hdmi_group=2
hdmi_mode=16

I also set

hdmi_force_hotplug=1

Yeah, I would expect 16 to work, but it gives me weird green ghosting all over the place…

Tried 9 since I wrote this post (800x600 @ 60hz), thats works fine… it should be able run at 1024x768 though…

Did you try with and without the hdmi_safe with 1024x768 ?

Works fine on my panel at least.
