The Samsung H6400 LED TV is the same TV as the H6350, but with 3D, a better remote, and a slightly different design. The picture quality is the same, which is really good, apart from the limited viewing angle.

Our Verdict

8.1 Mixed Usage

The picture quality of the Samsung H6400 is exactly the same as the cheaper H6350. It is worth the small premium if you plan on using the web browser a lot, simply for the better remote. The 3D is just a bonus.

  • 8.1 Mixed Usage
Pros
  • Great picture quality, both in dark and bright rooms.
  • Handles motion very well and has low input lag. This great for playing video games.
Cons
  • The frame has a clear plastic around it which feels a bit flimsy and increases the thickness of the borders.
  • Limited viewing angle. The colors change when viewed from the side.
  • Slight gray uniformity issues.

Look wise, the Samsung H6400 is almost exactly the same as the Samsung H6350. However, there is a clear border added around the frame (see following picture). That piece is flimsy and a bit useless.

As expected for a Samsung LED TV, the contrast ratio is great. The colors out of the box were also very good (see the next page for our full calibration settings).

Black Uniformity

The backlight uniformity is great, but there was one clouding spot in the top left corner.

Picture Quality
Gray Uniformity

The uniformity of gray is more problematic, but in this price range, you can't get much better than this. You will need to upgrade to the Samsung H7150 for better uniformity.

6.3
Picture Quality
Viewing Angle
Viewing Angle 23 °

The colors lose saturation when you view it off-axis. It isn't a deal breaker, but something to keep in mind if you have a really wide room.

8.5
Picture Quality
Average Room
Reflection 1.8 %
Surface Type Semi-gloss

It has a semi-gloss finish, so the reflections are more blurred than on the glossy screen of the pricier Samsung H7150. It reflects a little bit more, though, but it is definitely not an issue.

Max white 304.7 cd/m2

The Samsung H6400 can get very bright. You will have no problem with the screen, even if your room has a lot of windows.

The motion blur is very limited. The trail is short and the strobed backlight is effective.

Pretty much all Samsung TVs have the same input lag when you set the input type to PC or turn on Game mode. 44ms is not noticeable even for fast games.

Samsung's smart TV interface is great, with tons of apps and features. It is a lot faster than Sony's, especially for big USB drives. Check out our full review of Samsung's 2014 Smart TV platform.

Smart Features
Remote

The remote alone is worth the upgrade, compared to the cheaper Samsung H6350, as long as you plan on using the smart TV features a lot. You can control the cursor by just pointing at the TV.
