Needs a specific > soc table. Hi Eric, thanks for response, but it does not fix the issue for me. hdmi on mt7623 is DPI not DSI. There is already a mt7623 specific routing-table defined (one for DPI/HDMI and one for external=DSI/MIPI): https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/mediatek/mtk_drm_drv.c#L74 maybe it can be included or compared with the "default" route? regards Frank
