For info, this firmware is the one I got installed by default.
So I tried with HDMI output, in 1080p_60.
Both in HDMI and D output, I have black borders at the top and bottom of the screens. I reminds me of a 50Hz Mega Drive in 1990
If it can help the diagnostic, here is the "Status" info I get when using the D output :
720x576iPCM
1024x768pVLOCK
and with HDMI :
720x480iPCM
1920x1080pVLOCK
I am not sure it is correct as the ratio of the XRGB-Mini menus is not good (larger than high)
Another point : it seems the configuration is shared between the HDMI and D output. So any change in HDMI affects the D, and vice versa. Isn't there a way to save some profiles, one for each output or one for each system connected to the XRGB-Mini ?
The results I managed to get using the D ouput is now quite good (minus the borders), so I am a bit afraid to touch anything
Is it supposed to be significantly better using HDMI ?
PS : saw that the wiki has been updated with the suggested config for PS2, good if it can help others !
