For most setups, begin with the player’s video resolution set to Auto, then make sure every device and HDMI connection between the disc and display supports the picture format you want. For audio, route sound to the TV or receiver and choose an output format that device can handle. Menu names vary by player, so consult the manual for the exact controls.
Before changing settings, check the full signal chain
A 4K Ultra HD Blu-ray player cannot deliver HDR or Dolby Vision by itself. The disc, player, HDMI input, cable, any receiver or soundbar in the middle, and TV all affect what reaches the screen. A TV without HDR support may receive an SDR-adjusted picture instead.
Check the player, TV, receiver or soundbar model numbers, the HDMI ports in use, and the HDR formats listed for the disc. Dolby Vision on UHD Blu-ray requires support from the disc, player, and TV; an intermediary receiver or soundbar must also pass the video signal. HDR10 support does not establish that a player supports Dolby Vision. For example, Sony explicitly says Dolby Vision is not supported on the specific UHD player products covered by its product support page; that limitation should not be generalized to every Sony player.
Set video output and confirm HDR on the TV
Start with resolution set to Auto
For the Sony players covered by its HDMI specifications guidance, Sony recommends Output Video Resolution: Auto as the starting setting for optimum resolution. This is model-specific guidance, not a universal menu path or guarantee that every brand behaves identically. If a receiver is not 4K-compatible, Sony recommends trying Auto or connecting the player directly to the TV; the available choices depend on the model. See the Sony HDMI specifications guidance and your player manual.

Enable the TV and receiver’s enhanced HDMI mode if required
Some TVs require an enhanced or UHD signal mode for the HDMI input being used to accept 4K or HDR bandwidth. A receiver or soundbar between the player and TV must also pass the intended signal; it may have its own Enhanced Format setting. Check the manuals for the devices and the port in use. Sony includes checking these input-format settings among its 4K output troubleshooting steps.
Verify the format during playback
Play a disc known to contain HDR, then check the TV’s signal information or active picture mode to see what it is receiving. For Dolby Vision, Sony describes checking the TV’s Picture Mode display for Dolby Vision when the format is active and available. If you see SDR, lose 4K, or get a black screen, investigate the disc, ports, cable, and intermediary-device compatibility before changing picture presets. Sony’s troubleshooting guidance covers these kinds of signal-path checks.

- Play almost any disc and file format including DVDs
- Stunning picture with 4K upscaling up to 60p
- Easy set-up with included HDMI cable

Choose a compatible HDMI cable and connection path
Check the cable specification and the capabilities of every connected device before buying a replacement. Sony recommends an 18 Gbps High Speed or Premium High Speed HDMI cable for the UHD setup described in its UBP-X700 HDMI FAQ; its broader 4K output troubleshooting guidance likewise recommends a High Speed or Premium High Speed cable supporting 18 Gbps. These are Sony recommendations for the setups covered by those pages. A suitable cable cannot make a TV or receiver pass a format it does not support.
If a receiver or soundbar might be blocking HDR or 4K, test the player connected directly to the TV. If the desired picture format works on that direct path, check the intermediary’s supported formats, HDMI ports, and enhanced-format settings before restoring the original wiring.

Route audio to the right device and select its format
Match the player’s audio output to the HDMI connection
Some players have separate HDMI jacks for combined video/audio and audio only. Sony’s UBP-X700 FAQ describes that arrangement, while the UBP-UX80 instructions show model-specific HDMI Audio Output options—Auto, HDMI1, and HDMI2—that determine the route. These are examples, not universal labels. If you want sound from the TV, connect it to the output carrying audio and select the matching route. See the relevant player manual; Sony’s UBP-X700 FAQ and UBP-UX80 instructions illustrate the differences.
Use PCM when the destination needs decoded audio
A TV or receiver that cannot decode Dolby Digital or DTS may need the player to send two-channel PCM. Sony’s guidance for the covered BDP-S550 family recommends 2ch PCM in that situation, warning that unsupported formats can result in noise or no sound. This instruction applies to the devices covered by that guidance, not every player or receiver; check the receiving device’s supported formats and the player manual. See Sony’s BDP-S550 audio guidance.

Let a compatible receiver handle supported formats
When a receiver supports the soundtrack format, configure the player and receiver to work together rather than forcing PCM without a reason. In the specific UBP-X700 bitstream troubleshooting case, Sony directs users to set Audio (HDMI) to Auto and BD Audio Mix to Direct/Off so the receiver can decode supported audio. Those are model-specific steps; follow your own player and receiver manuals to determine whether Auto, bitstream, or another option is appropriate. See Sony’s UBP-X700 audio troubleshooting guidance.
Troubleshoot by symptom
- No Dolby Vision: Check whether the disc, player, TV, and any receiver or soundbar in the path support Dolby Vision. During playback, check the TV’s picture mode or signal information to confirm the format is active. Sony explains the format requirements in its Dolby Vision guidance.
- HDR falls back to SDR: Confirm that the content and TV support HDR, check the TV and intermediary-device HDMI format settings, and test a direct player-to-TV connection if a receiver or soundbar may not pass HDR. See Sony’s 4K output troubleshooting guidance.
- No 4K picture: Try the player’s Auto resolution setting where available, then check the receiver’s 4K compatibility, HDMI port capabilities, cable, and selected output route. Sony’s HDMI specifications guidance covers the Auto starting point, and its troubleshooting page covers the signal path.
- No sound: Confirm that the connected HDMI jack carries audio, the player’s output route matches that jack, and the TV or receiver is on the correct input. Use PCM if the destination requires decoded audio; for a compatible receiver, check the player’s audio-mix and output settings in its manual. Sony’s 2ch PCM guidance and UBP-X700 troubleshooting steps apply to the models they cover.
Which settings should you choose?
| Setup decision | Starting choice | When to change it |
|---|---|---|
| Player video resolution | Auto, where available; Sony recommends it for the players covered by its HDMI specifications guidance. | If 4K does not appear, check the receiver, ports, cable, and direct-to-TV path before choosing a different resolution. |
| HDR or Dolby Vision | Use the format supported by the disc, player, TV, and any device between them. | If the TV reports SDR or lacks a Dolby Vision picture mode during playback, verify format support and HDMI signal settings. |
| Audio for a TV or device that cannot decode the format | Two-channel PCM, where required by the destination; Sony recommends this for the covered BDP-S550 family when Dolby Digital or DTS is unsupported. | Use another format only if the destination supports it and the player manual confirms the appropriate output setting. |
| Audio for a compatible receiver | Use an output mode the receiver supports; Sony’s covered UBP-X700 bitstream case uses Audio (HDMI) Auto and BD Audio Mix Direct/Off. | Follow the specific player and receiver instructions if supported soundtracks are not being decoded. |
| HDMI cable | For the Sony UHD setups cited above, use a High Speed or Premium High Speed cable supporting 18 Gbps. | Replace a cable only after checking the capabilities of the connected ports and devices. |
These are compatibility decisions rather than universal picture or sound upgrades. The correct choice depends on what each device supports and how the system is connected.
