Best LG TVs 2020: LCD, OLED, 4K HDR

Best LG TVs Buying Guide: Welcome to What Hi-Fi?'s round-up of the best LG TVs you can buy in 2020.

When it comes to buying a new TV, it obviously pays to do your research and shop around. But if you've previously owned an LG TV and want to stick with the same look and feel, or you've done your research and established that one of the company's OLEDs is just what you're looking for, it's time to narrow your search down to a specific model.

It almost goes without saying now, but LG makes some of the best 4K OLED TVs around. Not only that, it also sells OLED panels to rival manufacturers such as Panasonic, Philips and Sony, who then use them in their own TVs. In short, there's no greater authority in OLED tech than LG.

All of the TVs recommended here are LG's own. All are 4K OLEDs that support HDR10, Dolby Vision and HLG (but not HDR10+), and all have HDMI 2.1 sockets that support next-gen features such as eARC (Enhanced Audio Return Channel), VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode).

All of the sets in our list use LG's own colourful webOS operating system. On the surface it looks good and is pretty simple to get to grips with, but if you've been reared on Android TV or Samsung's Tizen system, some menus take a bit of getting used to. It's also worth mentioning that LG's 2020 sets are currently lacking the UK's core catch-up apps, including BBC iPlayer. If you buy one of the 2019 models that's still available, you will get those apps, although you'll also get a slightly less accomplished picture performance.

Got all of that? Then here are the best LG TVs you can currently buy.

1. LG OLED48CX

LG has produced the first sub-50in OLED of the 4K era – and it’s just as brilliant as we’d hoped

SPECIFICATIONS

Screen size: 48in (also available in 55in, 65in, 77in) | Type: OLED | Backlight: not applicable | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: webOS | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 62 x 107 x 4.7cm

Reasons to Buy

Flagship-level OLED performance
Dramatic but natural picture
Forward-looking feature set

Reasons to Avoid

Missing UK catch-up apps
Pricey for its size

We've been waiting for this moment for a long time. Finally, you can buy a 4K OLED TV that's smaller than 55in. In fact, it's quite a lot smaller: the OLED48CX is, you guessed it, a 48in TV, and therefore brings flagship OLED performance to under 50in for the first time.

And it really is a fabulous performance. This isn't a downgraded flagship TV - it's a downsized flagship TV. It offers the same performance and features as its bigger brothers in the CX range (which, let's remember, also match the more expensive GX, RX and WX in terms of picture quality and processing), but in a smaller, more lounge-friendly package.

The performance is superb. The perfect blacks and near-perfect viewing angles we're used to from OLED, combined with bright, punchy whites and vibrant but natural colours. LG's motion processing in 2020 is the best it's ever been, too, and its OLEDs continue to impress in terms of upscaling 1080p and standard-def content.

On top of all that you get certified HDMI 2.1 sockets that support next-gen features such as eARC (Enhanced Audio Return Channel), HFR (High Frame Rate), ALLM (Auto Low Latency Mode), and all current formats of VRR (Variable Refresh Rate). Those last two features will be of particular appeal to those gamers looking to upgrade to the PS5 or Xbox Series X this Christmas.

One fairly big downside for UK buyers is that all of the UK's catch-up apps, including BBC iPlayer, are currently missing from LG's 2020 smart platform. You can obviously add these fairly easily and inexpensively by adding a streamer such as the Amazon Fire TV Stick 4K, but you really shouldn't have to.

2. LG OLED55CX

The core model in LG’s 2020 OLED TV range is an astonishingly capable all-round performer.

SPECIFICATIONS

Screen size: 55in (also available in 48in, 65in and 77in) | Type: OLED | Backlight: not applicable | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: webOS | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 71 x 123 x 4.7cm

Reasons to Buy

Picture is exciting but natural
Improved motion and dark detail
More future-proofed than most

Reasons to Avoid

Missing UK catch-up apps

We've already covered the new 48-inch version of the CX above, but it's worth remembering that the 55-inch model is still available and arguably offers better value for money.

For not a huge amount more, you get seven extra inches of OLED panel real estate and all of the excellent picture qualities and advanced features of its smaller sibling. It sounds a bit better, too, thanks to the bigger chassis, although the CX isn't the best-sounding TV in its class.

Of course, the 55in CX also shares its little brother's lack of UK catch-up apps, and that will put some people off right away, but if you can forgo the likes of BBC iPlayer (or don't mind adding them via an external source), this is an extremely compelling all-rounder.

3. LG OLED65GX

LG’s 2020 OLED TV range gets off to a superb start with this beautifully designed ‘Gallery’ model

SPECIFICATIONS

Screen size: 65in (also available in 55in, 77in) | Type: OLED | Backlight: Not applicable | Resolution: 4K | Operating system: webOS | HDR support: HDR10, HLG, Dolby Vision | HDMI inputs: 4 | USBs: 3 | Optical output: Yes | Dimensions (hwd, without stand): 83 x 145 x 2cm

Reasons to Buy

Consistent, natural performance
Improved motion and dark detail
Lovely design

Reasons to Avoid

Currently lacks UK catch-up apps
No feet or pedestal in the box

While most people will be more than satisfied with one of LG's C-class models, which are the most affordable sets with all of the company's best picture processing, this GX takes that same picture and adds more powerful sound and a beautiful design.

This is LG's 'Gallery' model, and as such is entirely intended for wall-mounting. You don't even get a stand in the box (although feet can be bought separately), with a low-profile mount provided instead. The set is a uniform 2cm deep, which is exceptionally slim. The CX, by comparison, is 4.7cm deep at its thickest point.

Picture-wise, LG has taken the exemplary performance of its 2019 OLEDs and improved it in a few key areas, with dark detail, colour richness and motion handling all getting a worthwhile boost. The set sounds decent, too, particularly for one with essentially invisible speakers.

The only issue for UK buyers is the current lack of catch-up apps such as BBC iPlayer, but LG assures us it's working on this. Either way, this is a stunning TV.

4. LG OLED65B9PLA

LG’s B9 OLED features combines a 2018 processor with a 2019 panel for extra affordability.

SPECIFICATIONS

Screen size: 65in (also available in 55in) | Type: OLED | Backlight: not applicable | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: Tizen | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 83 x 145 x 4.7cm

Reasons to Buy

Brilliant colour
Good detail
Great price

Reasons to Avoid

Average dark/light production
Audio a touch muffled

The LG B9 is a mixture of the old and the not so old – it combines the company's 2018 TV processor with its 2019 OLED panel. This makes it the most affordable model in LG’s 2019 OLED range and an even more tempting proposition than before thanks to recent discounts.

The picture is natural, colourful and well-measured for contrast whether you’re watching in 4K or upscaling from HD, and whatever processor power is missing certainly won't ruin your TV experience.

Looks-wise, this LG is typically neat. From the front, it’s virtually all screen with a miniscule frame and a small, central, black plastic plinth taking the weight of the set. Just four screws anchor the panel to the stand but it feels sturdy enough. 

Fully-certified HDMI 2.1 sockets bring with them a degree of future-proofing and there are more than enough sockets to accommodate any device you might care to attach. UK buyers also get access to the catch-up apps that LG's 2020 OLEDs are currently missing.

Catch-up apps aside, the new 2020 models are undeniably better and it's worth paying the extra for one of those if you can. As far as this price proposition goes, though, the LG OLED65B9PLA gets our full vote of confidence.
