This page outlines differences in functionality and features between Series 3 (XTx43, XDx33, HDx23, LS423) and Series 4 (XTx44, XDx34, HDx24, LS424) models.
HDR10, Dolby Vision
XTx43 players support HDR, while XTx44 players support both HDR and Dolby Vision.
Series 3 (XTx43/XDx33/HDx23/LS423) players support video-only .wmv (i.e. without .wma audio), while Series 4 (XTx44/XDx34/HDx24/LS424) players do not support the .wmv codec at all.
While XDx33 players can play two HD portrait videos simultaneously, XDx34 players can play only one HD portrait video at a time.
Both XTx43 and XTx44 players can play two simultaneous portrait HD videos.
Selecting a portrait mode in BrightAuthor will set all video zones in that presentation to portrait, while a custom BrightScript/HTML presentation can set video zones to portrait/landscape individually. This means that a BrightAuthor portrait presentation for XDx34 players is effectively a single-video presentation, while a custom BrightScript/HTML presentation for XDx34 players can have both a portrait and landscape HD video zone.
HDx23 players (and XTx43/XDx33 players that are rev G or earlier) do not support full RS-232 signaling. XTx44/XTx34/HDx24 players (and XTx43/XDx33 players that are rev H or later) support full RS-232 signaling. See here for more details.
XTx43/XDx33 players support the ATAPI logical interface for SSD, while the XTx44/XDx34 players support the NVMe interface. See here for more details.
Real Time Clock
All Series 3 and 4 players have a real time clock (RTC), except for the LS424. If you power cycle a player that does not have an RTC (and is not connect to the Internet), day-parted presentations will not play at scheduled times.
