Connecting Xbox to Sony DAV-TZ140 Home Theater via HDMI

Yes, you can connect Xbox (One / Series X|S) to the Sony DAV-TZ140 via HDMI.

Connection Steps

1. HDMI Cable: High-speed (18 Gbps) cable from Xbox HDMI OUT → DAV-TZ140 HDMI IN (labeled "BD/DVD", "TV", or "SAT/CATV").
2. Power On: Turn on DAV-TZ140 → press "FUNCTION" until correct HDMI input shows.
3. Xbox Settings: Settings → General → TV & Display → 4K/120Hz/VRR as supported. Audio: Bitstream Out → DTS / Dolby Digital (DAV-TZ140 decodes both).
4. DAV-TZ140 Audio: Ensure "HDMI Audio" = On. Select "Cinema" or "Game" sound mode.

Caveats

• DAV-TZ140 is 2008-era: HDMI 1.3a — supports 1080p/60, Dolby TrueHD/DTS-HD MA bitstream, not 4K, HDR, VRR, eARC, or Atmos.
• Xbox Series X|S: Will downscale to 1080p/60; HDR metadata ignored. Set Xbox to "DVI" or "HDMI - Automatic" → 1080p.
• Audio Only: If video passes through to TV via HDMI OUT (DAV-TZ140 has HDMI OUT to TV), ensure TV is on correct input.
• Optical Fallback: If HDMI handshake fails, use Xbox Optical Out (Series X has none; One S/X have TOSLINK) → DAV-TZ140 Optical In.

Verify Your DAV-TZ140 Inputs

Check rear panel: 3× HDMI In, 1× HDMI Out, 1× Optical In, 1× Coaxial In. Use any HDMI In.

Enjoy 5.1 surround for games/movies!
