If you’re in the market for a new TV, the words 'LG' and 'OLED' are probably going to feature somewhere on your shopping list.

Ever since it launched its first OLED TV in 2013, LG’s blazed a trail for the TV tech - and in 2018 we’ve reached the point where we can safely say its 2018 OLEDs are some of the best TVs the Korean giant has ever produced.

But with five different ranges to choose from and a couple of different size options in each, which LG OLED TV should you buy? What are the differences between them, and which is the best LG OLED for your money?

Allow us to answer all these questions and more below.

B8 vs C8 vs E8 vs G8 vs W8 - what are the differences between LG’s 2018 OLED TVs?

LG's model structure for 2018's 4K OLED TVs is similar to the approach taken in 2017 - the only difference being the '7' has been replaced by an '8'. There are five ranges in total, starting with the B8 entry-level line, followed by C8, E8 and G8, and ending with the wafer-thin W8 "wallpaper" OLED.

C8 to W8 all use LG's new custom-built Alpha 9 picture processor, while the B8 sets have a new version of LG's Alpha 7 processor from 2017.

All of LG’s 2018 OLED TVs support a wide variety of HDR formats, including HDR10, Dolby Vision, HLG and Advanced HDR by Technicolor. There’s no 3D support, but we have found the 2018 sets to be among the best when it comes to gaming.

LG claims the Alpha 9 delivers big improvements in noise reduction, sharpness, depth enhancement and colour reproduction. And, from what we've seen during our OLED55C8PLA and OLED55E8PLA reviews, we have to agree. Even the OLED55B8PLA doesn’t seem to overly be hampered by its lower spec processor.

While the OLED panel technology remains largely consistent between models, the main differences relate to aesthetics and speaker set-up. The stand designs vary between models with some using built-in speakers and others using a separate soundbar to handle audio.

The W8, for example, hangs on your wall like a picture frame and comes with a large external soundbar-cum-receiver which attaches via a slim umbilical cable.

Prices start at £2000 for the 55in B8 OLED, rising to around £15,000 for the flagship 77in W8 OLED.

It’s worth noting two different versions of the LG B8 OLED exist. One with a ‘PLA’ suffix and another with ‘SLC’. LG tells us the differences between the two sets are the stand design (Alpine on the 'PLA' versus Crescent on the 'SLC'), the speaker configuration (2.2 versus 2.0) and power output (40W versus 20W). We haven’t yet been able to test an ‘SLC’ B8 so, for now, we’ll have to take LG’s word for it.

LG C8 vs B8 - which is better?

On paper, it’s very close. At the time of writing there’s around £500 between the two, and this might be enough to sway you towards the B8. And understandably so.

However, our money would go on the C8, which brings a number of subtle improvements to aspects of the picture such as detail, clarity, contrast and colour. When you add them all together, it’s enough to convince us to spend a little extra.

Of course, if the price difference was to open up further over the coming months, the case for the B8 would become stronger.

LG B7 vs B8 and C8? Should I buy a 2017 LG OLED?

Good question. Shop around and you’ll find the LG OLED55B7V available for around £1300. This is a What Hi-Fi? Award-winner and Product of the Year from 2017 available for less than half price (we originally tested it at £3000). Who wouldn’t be tempted?

We’re not sure how much life is left in the B7, but if you want to experience the benefits this tech brings (including the true inky blacks only OLED can produce), and you can live with a slightly older model, you can buy the set with confidence.

Whether you’d forgo the B7 in favour of a 2018 model really depends on your budget (and how badly you want all the bells and whistles that the 2018 TVs bring). 

The B7 doesn’t have the new and improved 2018 OLED panel or the likes of ThinQ AI functionality, High Frame Rate (HFR) support (up to 120fps) and Google Assistant voice control. 

Is the OLED55C8PLA better than the OLED55B7V? Yes, in pure performance terms, it absolutely is. It produces a punchier, brighter and sharper image. It’s also a good-looking set and many will see it as the sweet spot of LG’s entire 2018 OLED TV range.

LG 2018 OLED TVs vs Samsung 2018 QLED TVs

While researching OLED, you’ll undoubtedly have come across Samsung’s QLED (Quantum dot Light Emitting Diode) TVs. And, you’re possibly wondering a) what’s the difference between the two technologies? and b) which is better?

The first thing to note is QLED isn’t simply the case of swapping a letter - it uses LCD panels, a completely different TV tech compared to OLED. You can learn all about it on our page dedicated to explaining QLED.

MORE: OLED vs QLED - which is the best TV technology?

Suffice to say, both technologies have their own strengths. Generally, OLED TVs tend to boast more impressive black levels, while QLEDs tend to produce a brighter overall image with more vibrant colours. It really is horses for courses - some people might prefer the balance of QLED, while others might opt for OLED.

We’ve compared Samsung’s premium Q9FN range to LG’s C8 series, and there isn’t much between them. The C8 just edges it due to the TV’s more rounded performance, but the there truly isn’t much in it. Opt for either range and you won’t be disappointed.

What about LG vs Panasonic, Philips and Sony OLED TVs?

Of course, LG isn’t the only show in town when it comes to OLED TVs. Other manufacturers including Panasonic, Philips and Sony have all come to the market with rival ranges. 

Virtually all manufacturers source the basic OLED panels from LG Display, but this doesn’t mean all OLED TVs look alike. Manufacturers design their own models and build their own internals, including picture processing engines and speakers, which delivers variances in picture quality from set to set.

And there are some great alternatives out there. The Philips 55POS9002 arrived in late 2017 and received a glowing five-star review. It can now be yours for a tempting £1499.

After a disappointing 2017, Panasonic seems to have returned to form in 2018. The recently reviewed 55in FZ802 and TX-55FZ952B both produc fantastic pictures for the money.

Sony has a number of LG-rivalling OLED TVs, not least its A1 range. Launched in 2017 and still going strong at the time of writing, the line-up boasts excellent 55 and 65in options. There’s also Sony’s AF8 range and recently announced AF9 Master Series to throw into the mix.

All of these TVs have different strengths and weaknesses but currently, for our money, LG’s own 2018 OLEDs are the best around.
