Hi Guys,
after upgrading my Raspi to the latest firmware (from May 24th 2014), it turned out I couldn’t specify any specific resolution. Pi always booted using the highest resolution possible from my TV (actually a 1080p screen). It’s definitely ok to run Emulation Station to that resolution but it’s a nightmare for the Pi to run emulators at such resolution (major slow downs).
I wanted to stick to the VGA resolution as recommended by petrockblog in the Advanced Configuration Wiki.
With new kernels you have to set a new parameter in the /boot/config.txt file to force Pi to use the resolution you like. Fire up your favorite editor:
~# sudo vi /boot/config.txt
And add “hdmi_force_mode=1” somewhere, ie:
# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=1
# mandatory with the newest kernel
hdmi_force_mode=1
Then simply reboot and voila!
~# sudo reboot
Cheers,
ThomaS
