QLED televisions use tiny particles called quantum dots to help produce color. If you are deciding how much that feature matters for movies or everyday viewing, consider it alongside resolution, refresh rate, and the lighting in your room.

How quantum dots help a TV produce color

In a common design, a blue backlight shines through a layer containing quantum dots. Some of that light is converted to red and green, and some remains blue. The more distinct primary colors can help the display reproduce a wider range of colors. The LCD panel still controls how much light passes through different parts of the image.

In a landscape scene, look for differences between several shades of green or for gradual changes across the sky. Those differences have to be present in the source to begin with. Picture settings and video quality also affect what you see.

Two Swiss Plus QLED models to look at

The official specifications for the 50-inch 50SST-8920QI9 and the 65-inch 65SST-8980QI9 list QLED, Ultra HD resolution, and a 60 Hz refresh rate. Start with the 50-inch model where space is tighter. Consider the 65-inch model if your setup can comfortably accommodate the larger screen.

How to compare two television pictures fairly

Where possible, compare two screens of the same size with the same version of a clip, similar picture modes, and the same viewing distance. Start with a daytime scene that shows a face and some foliage, then play a dim scene to look for shadow detail. If people watch from the side at home, try the angle of a side seat as well.

What to check for movies, sports, and everyday viewing

For films, start with skin tones and detail in dark scenes. For sports, look at camera movement and follow the ball in the kind of broadcast you actually watch. For day-to-day viewing, subtitle legibility and room reflections can make a difference you notice right away.

Find the right model for your space

Frequently asked questions

No. 4K describes resolution, while QLED describes a technology that helps produce color. Look for both specifications on the exact model page.

No. Refresh rate is a separate specification. Both Swiss Plus models in this guide list a 60 Hz refresh rate.

Choose a short clip you know well with a face, saturated colors, and soft shadows. Play the same version on both TVs at similar picture settings and viewing distances.
