This was discussed on the mythtv forum (link below). But here is a quick
summary.
use this command:
 QT_QPA_EGLFS_ALWAYS_SET_MODE="1" QT_QPA_PLATFORM=eglfs
QT_QPA_EGLFS_KMS_CONFIG=./pi_mythfrontend.json mythfrontend --noupnp
--logpath /tmp

and create ./pi_mythfrontend.json:
{ "device": "/dev/dri/by-path/platform-gpu-card", "outputs": [ { "name":
"HDMI1", "mode": "1920x1080 at 60" } ] }
