Sony UBP-X800M2 Review: 4K Blu-ray Player Tested

The Sony UBP-X800M2 sits in the equipment rack in my converted bonus room alongside an Apple TV 4K and an Nvidia Shield Pro. Each has a defined job. The Sony’s job is physical media , and for that specific role, owner reports and spec verification confirm it earns its place.

4K Blu-ray discs are not dead. A well-mastered disc at full bitrate carries more picture information than any current streaming service can deliver. If picture quality is your primary metric, you need a disc player in your chain.

Quick Verdict

The UBP-X800M2 is a competent, no-drama physical media transport. It reads 4K UHD, standard Blu-ray, and DVD reliably, passes Dolby Atmos and DTS:X bitstreams cleanly to a capable receiver, and supports HDR10 and Dolby Vision output. The app ecosystem is present but secondary , for serious streaming, a dedicated device handles that role better. Buy this because you buy discs.

Key Specs

| Feature | Detail | |, |, | | 4K UHD Blu-ray | Yes | | HDR support | HDR10, Dolby Vision | | HDR10+ | No | | Audio passthrough | Dolby Atmos, DTS:X, DTS-HD MA, Dolby TrueHD | | Internal audio decoding | Yes (LPCM output available) | | Streaming apps | Yes (Netflix, YouTube; limited selection) | | HDMI outputs | 1× HDMI (combined AV) | | Hi-Res Audio | Yes (SACD, CD, USB playback) | | Ethernet / Wi-Fi | Both | | USB port | Yes |

A critical note on HDMI: the X800M2 has a single HDMI output carrying both video and audio. There is no dedicated audio HDMI output. In a standard AV receiver setup , where the receiver handles video passthrough to display , this is not a problem. In a setup routing video direct to a projector and audio separately to a receiver, you will need an HDMI splitter or will rely on the ARC/eARC return channel. Plan your signal path before purchasing.

Performance

Picture Quality

Owner consensus on AVS Forum and verified buyer reports consistently cite clean, artifact-free 4K UHD playback as the X800M2’s baseline strength. HDR10 tone mapping is handled downstream by the display, and Dolby Vision metadata passes correctly when both the player and display support it.

HDR10+ is absent. For buyers who own an HDR10+-capable display and have titles that carry HDR10+ metadata , primarily Samsung-heavy catalogs and some Warner releases , the Panasonic DP-UB820 handles that format where the Sony does not. For most libraries, HDR10 and Dolby Vision cover the relevant titles.

Standard Blu-ray and DVD upscaling draws consistently positive owner reports. The gap between a disc played on this machine and a stream from the same title is audible to anyone who has watched both back-to-back.

Audio Passthrough

Dolby Atmos and DTS:X bitstream passthrough to a capable receiver is clean and verified across multiple owner reports. The Denon AVR-X3700H in this room decodes both formats without issue from the X800M2’s HDMI output.

Internal decoding is available for setups without a bitstream-capable receiver , the player outputs LPCM, and Dolby TrueHD and DTS-HD MA are decoded internally before transmission. Buyers upgrading from an older receiver that lacks Atmos decoding can still extract lossless audio in LPCM form.

SACD playback is supported, which matters to a subset of buyers with legacy high-res disc libraries. CD playback is clean. USB playback of FLAC and other hi-res formats works as described.

Streaming and App Ecosystem

Netflix and YouTube are present. The selection stops well short of a dedicated streaming device. Amazon Prime Video is absent from the app lineup , a genuine gap for Prime subscribers who want a single-remote solution.

The Nvidia Shield Pro remains the stronger choice for Plex and Kodi users, and the Apple TV 4K handles the Apple ecosystem cleanly. The X800M2 is not designed to replace either of those. Buyers expecting to rely on this player’s apps as their primary streaming interface will be disappointed. Buyers who understand it as a disc transport with supplementary apps will not be.

Load Times and Build

Disc load times draw some complaints in owner reports , the X800M2 is not fast. Cold boot to disc menu on a 4K UHD title typically runs 30, 45 seconds per multiple verified owner reports. For a device used specifically when you’ve decided to sit down and watch something, this is a minor irritant rather than a disqualifying flaw.

Build quality is mid-range Sony , plastic chassis, functional tray mechanism, lightweight. It is not a premium-feel unit. The remote is serviceable.

Pros & Cons

What works:

• Clean HDR10 and Dolby Vision 4K UHD playback
• Reliable Dolby Atmos and DTS:X bitstream passthrough
• Internal Atmos/TrueHD decoding for older receivers
• SACD, CD, and hi-res USB audio support
• Solid standard Blu-ray and DVD upscaling

What doesn’t:

• No HDR10+ support
• Single HDMI output limits signal routing flexibility
• App ecosystem is thin , no Amazon Prime Video
• Slow disc load times compared to competing players
• Build quality does not match the performance it delivers

Who It’s For

The X800M2 is the right answer for a specific buyer: someone building or maintaining a dedicated 4K Blu-ray library who already owns a capable streaming device and a receiver with Atmos decoding. It is not the right answer for someone who wants a one-box streaming and disc solution, or for someone building around an HDR10+-capable display who buys Warner or Samsung-catalog titles regularly.

For dual-format HDR buyers , those who want both Dolby Vision and HDR10+ from a single player , the Panasonic DP-UB820 covers both formats. The trade-off is a higher price tier and an app ecosystem that is similarly limited.

Buyers looking at the older Sony UBP-X800 should know that the M2 revision added Dolby Vision support, which the original lacks. If you are choosing between them on the used market, the M2’s Dolby Vision support is the deciding factor for a modern display chain.

The full range of disc players and streaming sources worth considering before committing sits at Players & Sources , worth a pass if you are still mapping your signal chain.

Buying Guide

Physical Media vs. Streaming: The Quality Argument

The claim that streaming has caught up to 4K Blu-ray is not supported by bitrate comparisons. A 4K UHD disc carries a video bitrate of 50, 100 Mbps depending on the title. Major streaming services delivering 4K content operate at a fraction of that. The compression difference is visible on a calibrated display at normal viewing distances, particularly in high-motion scenes and dark shadow detail.

This is the foundational case for owning a disc player in a quality-focused setup. If you are assembling a system around a projector and a calibrated display, discs are not optional , they are the reference source.

HDR Format Coverage

HDR10 is the universal baseline. Every 4K disc player supports it, and every 4K-capable display supports it. Dolby Vision adds dynamic metadata, adjusting tone mapping scene-by-scene rather than relying on a single static map for the full title. Most premium 4K titles include both HDR10 and Dolby Vision tracks.

HDR10+ is Dolby Vision’s competing dynamic metadata format, used primarily by Samsung displays and carried on a smaller subset of titles. If your display supports HDR10+ and your library includes titles that carry it, the Panasonic DP-UB820 is the only player in this tier that covers all three formats. The Sony X800M2 covers HDR10 and Dolby Vision only.

Choosing between them comes down to your display’s format support and your library’s composition. Most buyers on LG OLED or Sony Bravia displays are Dolby Vision users and the X800M2 covers their format set cleanly.

Audio Passthrough vs. Internal Decoding

A receiver with Dolby Atmos and DTS:X decoding should receive the bitstream directly from the player , the receiver does the decoding work and applies its own room correction (Audyssey, YPAO, MCACC, etc.) to the decoded signal. This is the preferred configuration for a full Atmos setup.

Buyers with older receivers lacking Atmos decoding can still extract lossless audio from the X800M2 via internal decoding and LPCM output. The player decodes Dolby TrueHD or DTS-HD MA internally and outputs the PCM result over HDMI. The receiver sees LPCM and passes it to the amplifier stages. Room correction still applies to the LPCM signal on most modern AVRs, so the practical difference from a listening standpoint is smaller than it appears on paper.

The limitation is channel count: internal decoding on the X800M2 outputs up to 7.1 LPCM. Height channel content for Atmos is folded down. For a full-height Atmos setup, bitstream passthrough to an Atmos-capable receiver is the correct approach.

Single HDMI Output: Routing Implications

The X800M2’s single HDMI output carries both video and audio. In a standard receiver-centric setup , player → receiver → display , this is not a constraint. The receiver handles audio decoding and passes 4K video to the display downstream.

In a projector setup where video routes direct to the projector and audio routes separately to the receiver, the single output requires a workaround. An HDMI splitter sends the signal to both destinations simultaneously, though splitter quality and HDCP handshake compatibility vary. ARC/eARC return channel is another option depending on display capability.

Planning the signal path before purchasing avoids surprises. The broader landscape of disc transport options and how they fit into different signal chain configurations is covered at Players & Sources.

App Ecosystem: Supplement, Not Replacement

The X800M2 includes Netflix and YouTube. Amazon Prime Video is absent. The app selection is genuinely thin compared to a dedicated streaming device.

Buyers who want a single device for both disc playback and comprehensive streaming should weigh this carefully. The stronger outcome for a quality-focused setup is a dedicated streaming device , Apple TV 4K, Nvidia Shield Pro, or a smart TV’s native app platform , handling all streaming, with the Sony handling only physical media. That separation is how this player performs best.

Frequently Asked Questions

Does the Sony UBP-X800M2 support Dolby Vision?

Yes. The X800M2 supports Dolby Vision output, which the original UBP-X800 does not. To receive Dolby Vision from a disc, both the player and display must support the format. Most current LG OLED and Sony Bravia displays support Dolby Vision, and the X800M2 will pass the signal correctly through a compatible receiver or directly to the display.

Does the X800M2 support HDR10+?

No. The X800M2 supports HDR10 and Dolby Vision but not HDR10+. If your display is an HDR10+-capable Samsung panel and you have titles that carry HDR10+ metadata, the Panasonic DP-UB820 is the player in this tier that covers all three HDR formats. For most LG and Sony display owners, the Sony’s HDR format coverage is complete.

Can the X800M2 pass Dolby Atmos and DTS:X to my receiver?

Yes, via bitstream passthrough over HDMI. The receiver must support Dolby Atmos and DTS:X decoding , the X800M2 sends the encoded bitstream and the receiver handles decoding. For receivers without Atmos decoding, the player can decode TrueHD and DTS-HD MA internally and output LPCM, though Atmos height information will be folded down in that configuration.

What streaming apps are available on the X800M2?

Netflix and YouTube are confirmed. Amazon Prime Video is not available on the X800M2’s app platform, which is a meaningful gap for Prime subscribers. For buyers who stream regularly across multiple services, a dedicated device , Nvidia Shield Pro, Apple TV 4K , is the stronger complement to the Sony rather than relying on the player’s built-in app selection.

Should I buy the X800M2 or the original UBP-X800?

The M2 added Dolby Vision support, which the original X800 lacks. On a current display chain that supports Dolby Vision , LG OLED, Sony Bravia, most current projectors with Dolby Vision , the M2 is the correct choice. The original X800 supports HDR10 only. On the used market where price differences are smaller, the M2’s Dolby Vision support is still the deciding factor for a modern setup.
