Question about Samsung One Connect

Good day. I have this box including a television. Now I want to switch to a projector and put the TV away. Now my question: can I use this box via HDMI for the projector? As an AV receiver, so to speak? In addition to HDMI, the projector has the following connections: RS-232 (1x), USB 2.0 Type-A (1x). Otherwise, please recommend an AV receiver. The projector is a pure playback projector. Thank you.
