Three 55-inch TVs: the best picture, the brightest, or the plain cheap one.

A sunny room favours the Hisense. A dim room shows off the TCL's blacks.
All three speakers are thin. Budget a soundbar if dialogue matters to you.
Prices here are for 55 inches. Both 50 and 65 inches exist in all three series.
The TCL and the Hisense dim zones of the backlight, so dark scenes look darker. The Samsung lights the whole screen at once, so blacks look grey at night.
The TCL and the Hisense each have two HDMI 2.1 ports and run games at up to 144 Hz. The Samsung stops at 60 Hz.
The TCL runs Google TV, the Hisense Fire TV and the Samsung Tizen. All have the big streaming apps.
Final buying advice: Best all-round picture and gaming: the TCL QM6K. Bright room: the Hisense U6. Just need a big screen for little money: the Samsung U8000F.

Yes, if you watch at night. The TCL and the Hisense dim parts of the backlight, so dark films look far deeper than on the Samsung.
The TCL QM6K or the Hisense U6. Both take 4K at 120 Hz on two ports. The Samsung tops out at 60 Hz.
Probably. Reviewers called the speakers thin on all three, though TechRadar found the Hisense better than expected.
We shortlisted 4K TVs that independent reviewers rate well and that we saw selling under $500 at a major shop, then compared them on the makers' specs.
We haven't tested these products ourselves. Our picks weigh independent expert reviews against each maker's published specs and the prices we checked. Opinions are ours; facts link to where they come from. How we choose.
