The Sony X91J is an upper-mid range 85 inch 4k LED TV. It's a new TV in Sony's 2021 lineup, and it's only available in this size as it sits alongside the Sony X90J, which is available in several sizes. It uses the same processor as some 2020 models, so it isn't as good in some areas as the X90J, but it still provides great picture quality that most people should enjoy. It comes with the new Google TV interface, which is user-friendly, and you have access to Google Assistant with the mic in the remote. It has two HDMI 2.1 inputs for high-frame-rate gaming, and it supports variable refresh rate (VRR) technology to reduce screen tearing, as long as you update it to the latest firmware, but VRR doesn't work at the same time as local dimming.
Our Verdict
The Sony X91J is great for most uses. It's excellent for watching movies or gaming in dark rooms because it has an excellent contrast ratio and exceptional black uniformity, but the local dimming causes some blooming. Gaming feels responsive thanks to its quick response time, fairly low input lag, and VRR support. HDR content also looks great as it displays a wide color gamut, but its HDR peak brightness is just okay. It's good for watching shows or sports in a bright room because it gets bright and has decent reflection handling, but it's not good for wide seating arrangements due to the narrow viewing angles.
- High native contrast ratio.
- Great SDR peak brightness.
- Two HDMI 2.1 inputs.
- User-friendly Google TV interface.
- Local dimming features causes blooming.
- Narrow viewing angles.
- HDR brightness is just okay.
The Sony X91J is excellent for watching movies in dark rooms. It displays deep blacks thanks to its high native contrast ratio, and the black uniformity is exceptional. It has a decent full-array local dimming feature, but it causes blooming around bright objects. It upscales 1080p or 4k content from Blu-rays or Ultra HD Blu-rays without issues, and it removes 24p judder from any source, which is great for watching movies.
- High native contrast ratio.
- Removes 24p judder from any source.
- No issues upscaling lower-resolution or 4k content.
- Local dimming features causes blooming.
The Sony KD85X91J is good for watching TV shows in a bright room. It gets bright in SDR and has decent reflection handling, meaning visibility won't be an issue in most well-lit rooms, but it's not the best if you want to place it opposite a bright window. Also, it doesn't have trouble upscaling 480p or 720p signals from cable boxes. Sadly, it has narrow viewing angles, so it's not a good choice for watching shows in a wide seating arrangement.
- Great SDR peak brightness.
- Decent reflection handling.
- User-friendly Google TV interface.
- Narrow viewing angles.
- Speakers have distortion artifacts at max volume.
The Sony KD85X91CJ is good for sports. Fast-moving players or balls look smooth due to the quick response time, and if you watch sports in a bright room, it gets bright enough to fight glare and has decent reflection handling. 720p content, like from cable boxes, also looks good. Unfortunately, it's not ideal for watching the game with a large group of friends because it has narrow viewing angles.
- Great SDR peak brightness.
- Quick response time for smooth motion.
- User-friendly Google TV interface.
- Narrow viewing angles.
- Speakers have distortion artifacts at max volume.
The Sony X91J is excellent for gaming. It has a 120Hz panel with HDMI 2.1 inputs that lets you play 4k games up to 120 fps. Motion looks smooth thanks to the quick response time, and it has an objectively low input lag, but it's not as low as some other TVs. It also supports VRR to reduce screen tearing, but it has some limitations as it doesn't support FreeSync and VRR doesn't work at the same time as the local dimming.
- High native contrast ratio.
- Quick response time for smooth motion.
- Two HDMI 2.1 inputs.
- Auto Low Latency Mode.
- VRR support after firmware update.
- Local dimming features causes blooming.
- No FreeSync support.
- Local dimming doesn't work at the same time as VRR.
The Sony X91J is great for watching movies. It performs well in dark rooms, thanks to its high native contrast ratio for deep blacks. It also has exceptional black uniformity. The local dimming feature performs decently, but it also causes blooming around bright objects in dark scenes. In terms of HDR, it supports Dolby Vision, but not HDR10+, and displays a wide color gamut, but its HDR peak brightness is just okay.

The Sony X91J is excellent for HDR gaming. It has great gaming features like HDMI 2.1 inputs, ALLM support, a quick response time, and fairly low input lag. It also supports VRR after a firmware update. HDR content looks great because it displays deep and uniform blacks and has a wide color gamut. However, its local dimming feature causes blooming, it doesn't get bright enough in HDR to make some highlights pop, and it doesn't work at the same time as VRR.

The Sony X91J is great to use as a PC monitor. It has fairly low input lag that delivers a responsive desktop experience, and motion looks smooth as it has a quick response time. It gets bright enough to fight glare in most settings, and it has decent reflection handling. However, it has narrow viewing angles, so the image looks inaccurate if you sit too close. While it displays chroma 4:4:4 with 4k @ 60Hz signals, text looks blurry with 4k @ 120Hz signals, which is disappointing.
- Decent reflection handling.
- Quick response time for smooth motion.
- Two HDMI 2.1 inputs.
- Narrow viewing angles.
- Can't display proper chroma 4:4:4 with 4k @ 120Hz signals.

Differences Between Sizes And Variants
We tested the 85 inch Sony X91J (KD85X91J), the only size available for this model. It's a larger version of the Sony X90J, but it uses the same processor as the Sony X900H, so the X90J and X91J aren't alike. You can see the differences between them below.
| Size | Model Number | Costco Model | Processor |
|---|---|---|---|
| 50" | XR50X90J | - | Cognitive Processor XR |
| 55" | XR55X90J | XR55X90CJ | Cognitive Processor XR |
| 65" | XR65X90J | XR65X90CJ | Cognitive Processor XR |
| 75" | XR75X90J | XR75X90CJ | Cognitive Processor XR |
| 85" | KD85X91J | KD85X91CJ | 4k HDR Processor X1 |

Popular TV Comparisons
The Sony X91J is a great large TV with picture quality that looks good in dark and bright rooms. It uses an older processor compared to its smaller sibling, the Sony X90J, so it isn't as good in a few areas, but most people should still be pleased with it. Considering there aren't too many 85 inch TVs available, it's a good choice if you want that size.

The Sony X90J and the Sony X91J sit alongside each other in Sony's 2021 TV lineup, but they have a few different features. The X90J is available from 50 to 75 inches, and it uses the Cognitive Processor XR processor, while the X91J is meant to be a larger variant with a different processor, the 4k HDR Processor X1. Both TVs are fairly similar overall, but the newer processor on the X90J has some advantages. Local dimming is much better on the X90J with less blooming, and it gets brighter, especially in HDR. The X90J delivers a sharper image when upscaling, but that's also because the 85 inch X91J has a lower pixel density, resulting in a less sharp image. Overall, while they're similar overall, the X90J is slightly better due to its processor.
The Sony X91J uses the same processor as the Sony X900H, and the 85 inch X91J performs a lot like the 55 inch X900H we tested. The local dimming features on each look similar to each other, but because the X900H has a smaller screen, the dimming zones aren't as big, so there's more blooming on the X91J. Other than that, they're very similar even though the X91J is a newer model.
The Sony X950H and the Sony X91J are both great TVs, but as the X950H is a higher-end TV, it's a bit better in a few areas. The X950H has a better local dimming feature, and it also gets brighter, making highlights pop more in HDR and making it a better choice for watching HDR content. The X950H also has wider viewing angles thanks to the 'X-Wide Angle' technology, but that means the X91J has higher native contrast. On the other hand, the X91J has HDMI 2.1 inputs, which the X950H doesn't have, and while it's only available in an 85 inch size, the X950H is available in smaller sizes.
The Sony X91J is better overall than the Sony X85J because it's a higher-end model. While we tested the 55 inch model of the X85J, it's also available in an 85 inch model like the X91J. The X91J has a few extra features that make it better overall, like a local dimming feature. Motion also looks smoother on the X91J due to its quicker response time. On the other hand, the X85J has a higher native contrast ratio, but this may also vary between units.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
