A compact OLED for a small room where picture depth matters more than screen size, and the smart platform covers streaming without a separate box. Check the stand footprint before you commit, since the base runs deep.

Overview
A small living room or den wall gets a self-lit OLED picture here, with each pixel making its own light instead of relying on a backlight. The screen itself vibrates to produce sound through Acoustic Surface Audio+, so dialogue comes from the image rather than a bar below it. Google TV runs the apps, and the set can sit on its included stand or hang from a VESA bracket.
Picture quality is the reason to look here: OLED contrast, Dolby Vision, and a processor that cleans up lower-resolution sources. The screen is small for a main room, so it suits a bedroom, office, or kitchen rather than a large family space. The stand base extends well forward, which matters on a narrow console.
Who it's for
Someone furnishing a bedroom, den, or studio apartment who wants an OLED panel without a wide wall. A household that mostly watches in a big room from across the space should look at a larger set instead.
Pros and cons
- Self-lit OLED pixels for deep black levels
- Dolby Vision and Dolby Atmos support
- Screen doubles as the speaker
- Four HDMI inputs for several devices
- Small screen for a main viewing room
- Stand base is deep, needs a wide surface
- No power consumption figure listed
- Screen finish and contrast ratio not quantified
Performance notes
Because each pixel lights itself, black areas stay dark without a backlight bleeding into them, which shows most in dark rooms. The Cognitive Processor XR analyzes and upscales content, and XR OLED Motion smooths fast action at the panel's refresh rate. Sound comes from the panel vibrating, so audio tracks the image but bass depth depends on the room.

Frequently asked questions
Is the Sony Bravia XR A90K a projector or a monitor?
Neither. It is a 42 inch OLED television with a built-in ATSC tuner and Google TV apps, so it works as a TV without extra hardware.
What comes in the box with the Sony A90K?
The bundle includes the TV, a remote control, the stand, a power cord, and manual documentation, plus a 2 year extended protection plan on top of the manufacturer coverage.
Can the Sony XR42A90K be wall mounted?
Yes. It uses a 400 x 400 mm VESA pattern, so a bracket with that spacing fits it, and the included stand is only for tabletop use.
Does the Sony A90K need a soundbar?
Not necessarily. Acoustic Surface Audio+ uses the screen as the speaker across 2.1 channels with Dolby Atmos, so a separate bar is optional.
