The following was enough to get it working here:
Quote:
# uncommented the following line
hdmi_force_hotplug=1
# added the following three
hdmi_cvt=2200 1650 33
hdmi_mode=87
hdmi_group=2
|
Changes were made to config.txt and rebooting was enough to see it work.
P.S. There is a band of black at the top and a smaller one at the bottom, so perhaps some tweaking is in order.
