4K Blu-ray Users Must Enable HDMI HDR Settings to Unlock Dolby Vision on 3 Formats

Summary
Many 4K TVs ship with advanced HDR over HDMI disabled, so discs may play only in baseline HDR10 unless users switch on settings such as Enhanced Format, Input Signal Plus or HDMI Ultra Deep Color.
Three HDR formats matter for 4K Blu-ray: HDR10 on every 4K TV, plus Dolby Vision and HDR10+, which require both a compatible TV and the right HDMI input mode.
Sony’s X90J shows a common limitation: one HDMI mode enables Dolby Vision while another prioritizes VRR, forcing some owners to choose features by port or manually toggle settings.
Dedicated 4K Blu-ray players from Sony or Panasonic are also needed for Dolby Vision or HDR10+; PS5 and Xbox disc playback is limited to HDR10.
The advice reflects a broader physical-media push by viewers seeking stable access and maximum picture quality as streaming libraries shift and older Blu-ray hardware sees few upgrades.
