Intro & Key features


It's raining high-end TVs

Regardless of which research report you believe in, the current leaders in the premium TV market (i.e., screen size of at least 55 inches) are Samsung, LG, and Sony. According to research firm GfK, Samsung - the biggest TV maker in the world for the last 12 years - has a 40% market share of the premium segment. But this figure includes TVs that cost less than US$2,500. Take those away and IHS Markit argues that in 2017, it’s Sony and LG that are making the most money in this premium category, with a 36.9% and 33% revenue share respectively.

If you’re looking for a common thread between Sony and LG, it’ll be that both sell OLED TVs. Since Samsung stopped investing in OLED TVs in 2015, global sales of OLED TVs, led by LG, have actually been growing steadily. According to a June report by IHS Markit, OLED TVs sales have outpaced QLED TV sales in the past two quarters. If you were to drill down further, during this period, LG sold 864,000 OLED TVs, while Samsung sold 751,000 QLED TVs.

And it’s against the backdrop of this premium TV war that I segue into my LG Signature W8PTA OLED TV review.


What is the LG OLED W8PTA?

The W8 still runs WebOS, now at version 4.0.

The highest-end model in LG’s 2018 TV lineup, the Signature W8PTA (simply called W8 henceforth) is the direct successor to the 2017 W7T. I’ve covered the new lineup in an earlier report, but in case you missed it, here’s a rundown of the new OLED TVs’ key features:

1.) α processor - LG has made a new processor for its 2018 TVs and has even given it a name: α (Alpha). There are actually two chips - α9 and α7 - with the former used primarily in the OLED TVs, including the W8.

A key benefit of the α9 processor is that it allows the TV to do a four-step noise reduction process. There’s a new color correction algorithm that supposedly expands the reference color coordinates seven-fold compared to last year’s processor.

2.) 120fps HFR - LG’s 2018 OLED TVs support 120 frames per second (fps) high frame rate (HFR) for a smoother picture than what’s possible on 60fps sets. However, because the TVs don’t have HDMI 2.1, you can only get HDR (HEVC) content from the TVs’ built-in streaming apps instead of from external, HDMI-connected sources.

3.) “4K Cinema HDR” - The new OLED TVs continue to support many types of HDR formats, such as the baseline HDR10, Dolby Vision, Hybrid Log-Gamma (HLG), and Advanced HDR by Technicolor.

You may also see LG using words like “HDR10 Pro” and “HLG Pro” to describe their TVs - these are just marketing terms used to describe HDR content that have gone through on-device processing. For example, the TVs can take regular HDR10 signals and use proprietary algorithms to dynamically tone-map each frame to get better brightness and contrast.

4.) Dolby Atmos - The new OLED TVs again support Dolby Atmos object-based surround sound processing.

5.) WebOS + ThinQ AI - LG’s TVs in the last few years were powered by WebOS, and the 2018 models are no different. With the newest WebOS 4.0, you still get a launch bar for easy access to apps such as Netflix, YouTube, Toggle, and features such as Miracast Overlay and Screen Share.

The biggest addition is what LG calls “ThinQ AI”. At present, ThinQ AI on LG TVs refers mainly to their intelligent voice control system. For now, the voice commands are for changing of TV settings and simple web searches; but LG has promised a firmware update later this year that will enable more advanced searches. (For example, you can say, “Show me all the movies with Tom Cruise”, and the TV will display results from the web, YouTube, Netflix, etc.)

While we saw Google Assistant integration on the TVs at CES 2018, this integration is region specific, and right now it isn’t activated here in Singapore. The various LG folks I’ve spoken to all told me that the TVs are basically Assistant-ready, and they’re just waiting for Google to officially enable Assistant support on them.

6.) “Wallpaper TV” (W8) - Like last year’s W7, the W8 adopts a “picture on wall” design. You’ve to wall-mount it because it’s quite literally a sheet of OLED panel. All the chips and ports are housed in a separate, Atmos-capable speaker bar (4.2-channel, 60W) that you connect to the TV with a flat ribbon cable.

The W8 has to be wall-mounted - there's no way to tabletop-mount it.

The W8 is part of LG's Signature lineup, which is a way of saying it has the best design, uses the best material, and costs the most.

The 65-inch W8's soundbar is a 4.2-channel, 60W front-firing speaker system. Click to experience how these speakers reveal and conceal away!

The W8's smart remote control (LG calls it Magic Remote) has dedicated Netflix and Amazon shortcut buttons.
