The LG Signature Oled TV (OLED65G6T) is a marvel of engineering. From the side, this 65-inch TV set is as thin as a sheet of cardboard.

LG says that its ultra-thin design, measuring just 2.57mm thick, was achieved by mounting the screen on a large sheet of glass.

Hence, the TV set does not have a traditional bezel.

The electronics and connectors are located in the screen-wide TV stand, which can be folded back if you wish to wall mount the TV set. The stand also has an integrated sound bar speaker developed by Harmon Kardon that delivers more punch than other skinny TV sets.

But the outstanding industrial design is simply the icing on the cake.

The G6's best feature is its Oled (Organic Light-Emitting Diode) screen. Unlike conventional LCD TV sets, Oled sets do not require a backlighting system to illuminate the picture.

In other words, dark scenes in a movie appear pitch black, as they do on the G6. In fact, this TV set produces the deepest blacks I have ever seen, sufficient to win over even the most loyal plasma TV fans.

The G6 can also produce a high level of brightness, satisfying the requirements to receive an Ultra HD Premium badge.

Because of its Oled screen, the TV set looks fantastic from any angle, with little degradation in contrast.

It plays HDR content in both the HDR10 format and the proprietary Dolby Vision format, currently available only on TV sets from LG and Vizio (the latter not available here).

I tested this with the Marco Polo TV series. On non-Dolby Vision TV sets, it is shown in the HDR10 format. While the G6 supports both formats, the Marco Polo TV series is shown in the Netflix app in Dolby Vision - you cannot choose to watch it in HDR10.

Without a side-by-side comparison, I could not really tell if Marco Polo in Dolby Vision looks better or worse than HDR10. All I can say is that the TV show, with its numerous torch-lit night scenes, looks stunning on the G6.

The G6 comes with two remote controls - the Slim Remote has fewer buttons than the Magic Remote, though the latter has a mouse pointer function that is useful for navigating its webOS TV interface. The Magic Remote supports voice search, too.

Apps such as Netflix, YouTube and even Spotify are available on the G6, though the selection is far more limited than that of an Android TV set.

The interface could be more streamlined. For instance, I had to update the existing apps individually, instead of having an option to update all of them simultaneously. And do I really need the TV to remind me to sign up for Netflix?

The newest feature in webOS TV is the ability to connect your mobile device to the TV set, via the LG TV Plus app (Android and iOS), in order to control the TV or to show content from your phone on the TV set. It works pretty well, especially for streaming photos and videos to the TV set.

My only reservation is the price. At $12,999, the G6 costs almost twice as much as its LCD competitors. It is for this reason that the G6 fails to get a perfect score.

The G6 is not just a near-perfect TV set, but also a status symbol. For those who simply want to enjoy a similar level of picture quality without seeming ostentatious, I would recommend LG's second-best Oled TV, the E6, which costs $7,499 (55-inch) and $9,999 (65-inch).
