Best LG TVs 2021: 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 2021.

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. 

Holding out for LG's first 42-inch OLED TV? It's rumoured to be launching in "early 2022".  

Right, here are the best LG TVs you can buy in 2021...

Reasons to buy
+Superb all-round picture quality+Near-flawless feature set+Better remote and menu system
Reasons to avoid
-Marginal gains on last year’s CX-Unengaging audio

In performance-per-pound terms, the Award-winning C1 is the standout model in the LG 2021 TV line-up. In fact, it's one of the most recommendable TVs available right now. It isn’t much of an improvement on its predecessor, the CX, but there wasn’t much that needed improving. 

Picture performance and features are exemplary. A strong app selection includes NetflixAmazon Prime VideoDisney+ and Apple TV, all with full support for 4K, Dolby Vision and Dolby Atmos. You also get an improved webOS 6.0 menu system new Cinematic Movement motion processing.

The 2021 LG G1 offers an even better picture in terms of brightness, sharpness and detail, but we're not talking huge margins and most people will struggle to justify the extra £500 ($500). Sound is average so you should budget for a separate sound system or soundbar to accompany your new TV.

When you balance the price against the stunning picture, the C1 tops our list of the best LG TVs. We tested the 65-inch size but it's also available as a 48-inch, 65-inch, 77-inch and 83-inch.

2. LG OLED65G1

LG’s new 'OLED Evo' TV is a real beauty.

Specifications
Screen size: 65in (also available in 55in, 77in)
Type: OLED
Backlight: not applicable
Resolution: 4K
HDR formats supported: HDR10, HLG, Dolby Vision
Operating system: webOS 6.0
HDMI inputs: 4
ARC/eARC: eARC
Optical output: Yes
Dimensions (hwd, without stand): 83 x 145 x 2cm
Reasons to buy
+Brighter, punchier and sharper+Beautiful when wall-mounted+Improved remote and app offering
Reasons to avoid
-No feet or stand in the box-Sound lacks excitement

For the last few years, LG's C-class model has offered the tech giant's latest and greatest picture processing tech at the most affordable price. Not any more. For 2021, LG has introduced a new ‘OLED Evo’ panel that promises increased brightness and sharpness, and to get the Evo panel you have to step up from the C1 (above) to the G1. 

If you'll willing to splash out the extra $500/£500, you'll be handsomely rewarded with the best OLED TV that LG has ever made (although not the necessarily the best value for money, of course). It's a stunning picture performer packed with apps and next-gen HDMI features, including 4K@120Hz on all four sockets, making it a great choice for gaming.

Sound is less impressive, but as always, we'd still recommend adding a separate soundbar to make the most of this stunning premium set. 

Downsides? The G1 is designed to be wall-mounted, hence why there's no stand or feet in the box. Bespoke feet can be bought separately but they’re quite expensive (£99).

Still, if you are planning to wall-mount, and you want a state-of-the-art LG OLED with a sleek 'Gallery' design, the G1 should be high on your list.

3. 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 2020 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 was excellent, 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 make the most of a PS5 or Xbox Series X.

The CX might have been superseded by the 2021 C1 (above) but the CX remains a great buy, especially if you can pick one up at a discount.

4. 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.

With the 55in CX having been outshone by the newer, 2021 55in C1, you might well be able to score this TV at a significantly reduced price online. You'll see we've listed today's cheapest price to the right. Overall, the CX remains an extremely compelling all-rounder.
