[PATCH 3/4] drm/bridge: dw-hdmi: do not force "none" scan mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jonas Karlman <jonas@xxxxxxxxx>

Setting scan mode to "none" confuses some TVs like LG B8, which randomly
change overscan procentage over time. Digital outputs like HDMI and DVI,
handled by this controller, don't really need overscan, so we can always
set scan mode to underscan. Actually, this is exactly what
drm_hdmi_avi_infoframe_from_display_mode() already does, so we can just
remove offending line.
