The UBP-X700 is Sony's mainstream 4K UHD Blu-ray player and one of the few sub-$200 decks to support both Dolby Vision and HDR10. Its rear panel keeps it simple: a TWIN HDMI architecture (HDMI 2.0a video+audio + HDMI 1.4 audio-only for legacy receivers), a single coaxial S/PDIF digital output, and a 10/100 LAN port. The only USB jack is on the front for media playback. Power is supplied by an external 12 V DC brick — there is no IEC mains inlet on the chassis.

Notes & Compatibility
Twin HDMI architecture. HDMI OUT 1 carries video and audio at 18 Gbps with HDR10 and Dolby Vision; HDMI OUT 2 is HDMI 1.4, audio only, and passes no picture at all, so it feeds a legacy AV receiver while OUT 1 runs straight to the TV. Sony specifies a Premium High Speed or High Speed HDMI cable rated 18 Gbps on OUT 1 for 4K HDR, and a cheaper lead is the usual cause of dropouts here. Dolby Vision arrived in a post-launch firmware update, so an unpatched player will not offer it; HDR10+ is not supported at all. Digital audio out is a single coaxial S/PDIF, with no optical TOSLINK on this model, so an optical-only soundbar needs a converter. There are no analog audio outputs. LAN is 10/100 BASE-TX, not Gigabit. Power is the supplied AC-M1215UC 12 V 1.25 A adaptor, which Sony says should not be substituted.
