Overview
An edge LED backlight shines in from the sides of a QLED panel, and Quantum HDR processing shapes the picture for supported HDR content. Alexa is built in, with voice control through the supplied remote.
A fast panel refresh and four HDMI ports make it a flexible hub for game systems and set-top devices. The limits: speaker output is modest, and the page gives no peak brightness, local dimming detail or contrast figure.
Who it's for
Households that connect many devices and like voice control through Alexa on the remote match the set. Those watching in a bright room, or needing detailed brightness data, should look for a model whose listing provides it.
Pros and cons
- Fast refresh panel
- Four HDMI ports
- Alexa built in
- Quantum HDR processing
- Contrast listed only as high
- Edge LED backlight type
- Modest speaker output
- Software update support unknown
Performance notes
With edge lighting, the LEDs run along the panel border, so brightness is spread through the screen rather than controlled zone by zone. Quantum HDR processing maps HDR content to the panel, and the refresh rate matters mainly for gaming and fast motion. Built-in speakers are low in output, so a sound system helps for movies.
