LG OLED65GX

The LG OLED GX ‘Gallery’ (OLED65GX) series is the black tie range-topper in LG’s 2020 OLED TV line-up.

While it shares an identical panel and picture processing specification to its more affordable CX stablemate, it warrants the top slot thanks to a single-depth (20mm) design that allows it to hang flush against the wall.

Beauty isn’t just skin deep though. This GX boasts advanced image processing, aided by AI Deep Learning techniques, handy for HD upscaling, and the eagerly anticipated Filmmaker Mode, as endorsed by Martin Scorsese and a host of La La Land talent.

The GX family comes in 55-, 65- and 77-inch sizes.

LG OLED GX design — Premium build quality, the perfect upgrade for any wall

The GX gallery is unquestionably premium looking. Cosmetics and finish are top notch.

As the bezel is just 5mm thin, it gives the impression that its images float in space. Of course, the GX doesn’t have to be wall-mounted. You can perch it on an AV rack in the time-honoured fashion, although you’ll need to buy a pair of optional feet to keep it upright (these’ll set you back another £99).

Connections comprise of four HDMIs (HDMI 2 supports eARC), three USBs, an optical digital audio output and Ethernet LAN. Wireless connectivity comes via Bluetooth and Wi-Fi, along with Airplay 2 support.

All HDMI inputs support 4K up to 120Hz, which makes the TV a good option if you’re looking to upgrade to a next gen console like the PlayStation 5 or Xbox Series X. Indeed, it’s well suited for gaming in general, with ALLM (Auto low Latency Mode) and VRR (Variable Refresh Rate). PC enthusiasts can take advantage of NVIDIA G-Sync.

LG OLED GX features — with Freeview Play AWOL this set lacks catch-up appeal

For such a futuristic flatscreen, it’s perhaps surprising to find Freeview Play missing. This means the set arrives without any mainstream catch-up TV apps on board. The company says it’s negotiating to add individual channel players to its webOS smart platform, but the absence of an up to date terrestrial tuner does seem a bit odd.

LG has also made its Bean Bird mascot redundant, ostensibly in order to simplify installation. We kinda miss the little guy.

LG’s webOS smart TV platform has seen some minor tweaks, but generally looks much as before. It’s home to all the popular streaming content apps, including Disney Plus.

New attractions this year are Filmmaker Mode and Dolby Vision IQ. The former is a cross manufacturer initiative, driven by the UHD Alliance, which allows you to watch movies with settings akin to those seen in Hollywood mastering suite. Filmmaker Mode has received numerous endorsements from the filmmaking community, and clearly has purist appeal.

Dolby Vision IQ is slightly different, in that it allows the screen to present Dolby Vision HDR without compromising shadow detail and image subtleties in rooms with ambient light. Rather confusingly, there’s no specific Dolby Vision IQ label, instead the feature masquerades as a Dolby Vision image preset, working in conjunction with the set’s AI brightness control function and ambient light sensor. You’ll soon forget it’s even there, which is probably a good thing.

LG OLED GX performance — Sublime 4K image quality enhanced by artificial intelligence

One aspect of the GX that doesn’t disappoint is image quality. Pictures look positively sumptuous, with superb contrast, excellent near black detail and lush colour fidelity. Obviously, what you see is governed by the various image presets available, so choose carefully. Some allow the screen to (literally) shine, while others constrain quite aggressively.

Presets include Cinema, Sports, HDR effect, ISF expert for Bright Room and Dark Room, Vivid and Standard. For those who don’t intend to chop and change, the latter is invariably the best option.

Filmmaker Mode is the most contentious addition. The aim to replicate a studio mastering monitor may be laudable, but in the process picture processing and noise reduction have been benched. With HD SDR content, the mode also drags overall image level brightness down to 100 nits – and that’s dim. Christopher Nolan might approve, but casual viewers will be less impressed.

Filmmaker Mode improves considerably with 4K HDR content. The average picture level lifts and the image regains some punch – WW2 actioner Midway (UHD Blu-ray) looks perfectly filmic. We wouldn’t advocate using it with cinematic TV shows though.

The GX, apparently, will auto switch to Filmmaker Mode, when there’s a metadata flag telling it to. As yet, this doesn’t exist, so instead, it needs to be treated like any other image preset.

LG’s Alpha 9 Gen 3 image processor does a phenomenal job on both HD and 4K content sources. Feed the set something truly extraordinary, like the 4K 60fps presentation of Gemini Man (UHD Blu-ray), and panel clarity really excels. Long lingering close-ups of Will Smith’s face seem almost 3-dimensional, while the sheer amount of detail held in the ‘shooter on the roof’ sequence is mesmerising.

The GX OLED supports Dolby Vision, regular HDR10 and HLG, as now used by Sky Q. There’s no support for HDR10+ though.

Overall HDR performance is in line with expectations, although we’ve seen brighter. We measured HDR peak brightness at around 750 nits (cd/m2) in Standard mode, which allows specular highlights (bright street lights, reflections, car headlights and so forth) to ping from the picture. Opt to watch movies on LG’s Cinema setting, and HDR peak output drops to around 650 nits. Embrace the oversaturation of Vivid mode, and HDR peaks get a corresponding boost.

The GX may lack any fancy audio innovations, but it doesn’t sound half bad for a flatscreen. There’s a claimed 60w of total amplification on-board, and it certainly makes a fair noise. Just as AI plays a role with picture performance, the GX comes with AI Sound Pro, which creates a more pronounced soundstage and adds a bit of mid-range weight.

The set’s gaming performance is creditable, with an input lag of just 13.2ms (1080/60), when in Game mode.

Should you buy the LG OLED65GX?

If your interior designer insists you have the slickest wall-mounted OLED money can buy, then look no further. Designed for seamless wall-mounting and a treat to look at, the GX more than warrants its high-end ‘Gallery’ handle. Image quality is excellent too, helped by ingenious AI picture processing technologies.

But the set’s good looks come at a price premium, especially considering that identical image performance can be had for less within LG’s own 2020 TV line-up. And that lack of Freeview Play tuner just seems careless…
