Four HDMI2.0 inputs, of course, including HDCP2.2 for 4K HDR on the OneConnect box.

The following connections are located on the One Connect Box from left to right:
CI slot for inserting a module for decoding.
Three USB2.0 ports (Samsung seems to be satisfied with the speed of USB2.0, after all they have equipped one port with 1 ampere instead of the usual 0.5 and declared it as an HDD port. This should provide enough start-up current for all 2.5-inch hard drives.)
Ethernet connection (100MBit/s)
Toslink output for digital sound transmission (e.g. to an AV receiver that does not support ARC)
Four HDMI2.0 inputs, of course, including HDCP2.2 for 4K HDR
Various signal inputs (two DVB-S2, C and T2 tuners each available)
The One Connect connection for the optical cable to the television set
Power connection
