Our take on the Samsung DU6900 Crystal UHD 65" 4K Ultra HD Smart LED Tizen TV

The Samsung DU6900 is a 65-inch 4K LED TV in Samsung's entry-level Crystal UHD line. It runs the Tizen smart platform with AI-powered picture processing, and it covers the basics well: 4K resolution, HDR support, voice assistants and a full app library. It suits buyers who want a big-screen Samsung smart TV without paying for Mini-LED or OLED. Against rivals like the TCL Q6 and Hisense U6, it gives up local dimming and wide color, so contrast and brightness in dark scenes are weaker.

Questions and answers

Is the DU6900 good for gaming?

It handles 4K gaming at 60Hz and has a low-latency game mode, but there is no 120Hz support or variable refresh rate. Serious console gamers should look at a step-up model.

Does it have local dimming?

No. The DU6900 uses edge lighting without local dimming, so black levels are gray compared with Mini-LED or OLED sets.

What is in the box?

The TV, a stand, a remote, and a power cable. A wall mount and HDMI cables are sold separately.

Does it support voice assistants?

Yes. Bixby is built in, and Alexa and Google Assistant work through the TV or connected devices.

How does it compare with the TCL Q6?

The TCL Q6 adds local dimming and usually a brighter panel, while the DU6900 offers Samsung's Tizen software and processing. Picture contrast favors TCL; app experience favors Samsung.

Can I mount it on a wall?

Yes. It uses a standard VESA wall mount, which is not included.
