Best LG C4 Prime Day deals: get the 5-star C4 OLED TV at the lowest price

Prime Day in October, aka Prime Big Deal Days, is in full swing, and the LG C4 is currently cheaper than it's ever been at several sizes. In other words, if you've been waiting for the prices to drop, now is a great time to buy.

With the C4, LG is once again the king of mid-range TVs. The C-series has long been considered the near-perfect intersection of performance, features and price, but the C3 was a bit disappointing in that it didn't push things on a great deal from the C2.

The C4 is different, though, with meaningful tweaks to the picture and sound performance, LG is back on top, which is probably why you're considering it as your next TV.

The C series has always been dependable, especially for gamers thanks to its four full bandwidth HDMI 2.1 sockets, 4K/120Hz gaming support and VRR and ALLM features. And while it doesn't feature the Micro Lens Array (MLA) screen technology of its bigger and more expensive G4 sibling, it still manages to dazzle with punch and vibrancy, while also remaining balanced and natural.

The C4 comes in six sizes: 42, 48, 55, 65, 77 and 83 inches. We've reviewed the 42-, 48- and 65-inch models, and they've all excelled, picking up five-star reviews.

One thing to note about OLED TVs is that they're not (usually) cheap. So if you've got your heart set on a C4 but don't want to shell out nearly £3000, then you've come to the right place.

LG OLED42C4 (42-inch)

Launch price: £1400 / $1500 / AU$2200

There aren't many 42-inch OLED TVs around at the moment, which is to the OLED42C4's advantage. Of course, it also helps that it's a phenomenal TV, compressing the specs of its bigger siblings into a smaller screen.

That means four HDMI 2.1 ports enabling 4K/120Hz, VRR and ALLM, a refresh rate of up to 144Hz for high-end gaming PCs, HGIG, NVIDI G-Sync and HDR support for HDR10, HLG and Dolby Vision.

Its picture is dynamic enough to be cinematic (not easy on such a small screen), its motion is solid and of course it's a treat for gamers. The only downside is its audio, which is underpowered and imprecise. But that's typical of most TVs this size.

LG OLED48C4 (48-inch)

Launch price: £1500 / $1600 / AU$2499

The main difference between this and the 42-incher is the stand. The 42-incher has feet, while this model (and every other size) has a pedestal stand. Because the stand is positioned centrally, it should fit a wider range of surfaces than the smaller model. Though given how small the 42-incher is, it shouldn't be too hard to find it a suitable surface.

The pedestal stand does make it a bit trickier to fit a soundbar, however. The 48-incher doubles its smaller sibling's sound output (40W compared to 20W), but it will still be improved by a soundbar (as all TVs are).

Otherwise, its specs are the same as the 42-inch model, and its picture is equally impressive, with all the richness and solidity of its larger siblings. It handles bright highlights exceptionally well, and the image generally is incredibly detailed. Fore more info, check out our full review.

LG OLED55C4 (55-inch)

Launch price: £1900 / $1999 / AU$3299

The C3 models sized 55 inches and above featured brighter OLED panels than the smaller versions, so we would assume this is the case again this year. Though there is increased brightness across the range, including the smaller models we've tested.

You get the same Alpha 9 Gen 7 processor as the other models, and the same 40W speaker system as the 48-inch variant. The 55-incher has the same stand as the 48-inch model too.

LG OLED65C4 (65-inch)

Launch price: £2700 / $2699 / AU$4299

The 65-inch C4 is a great TV. We've tested it, so we can say so with confidence. From the spec sheet, you can't see much difference from the C3 it replaces, but in person it's a different beast.

The gaming specs are a little better, with the refresh rate upping to 144Hz for PC gamers and full Nvidia G-Sync VRR certification. The audio has also been upgraded to virtual 11.1.2 sound upmixing (up from the 9.1.2 of the C3) with enhanced voice remastering for greater dialogue clarity. But these don't tell the full story.

The picture quality is significantly brighter and punchier than the C3, putting it back above the Sony A80L. This added richness and vibrancy combines with a more natural authenticity to create stunningly lifelike images. The sound too is streets ahead of its predecessor: it's weighty, punchy and dynamic, though like almost every TV in existence, it will be beaten by a half decent soundbar.

Even if you can't stretch to a soundbar, you'll be well served by the 65-inch C4. It's one of the frontrunners for TV of the year so far. And in the UK, it launched at a cheaper price than the C3!

LG OLED77C4 (77-inch)

Launch price: £3800 / $3699 / AU$5999

Now this is just getting silly. It's basically the same TV as the five-star 65 incher, but enlarged to a quite ridiculous 77 inches.

It has to make do with the same 40W speaker system as every model from the 48 incher up, which might feel quite underpowered with a screen this size. But if you're spending this amount on a TV, the least you can do is partner it with a soundbar. Better yet, opt for a full surround sound system.

LG OLED83C4 (83-inch)

Launch price: £6000 / $5399 / AU$7999

Is the 77-inch model too small for you? Maybe the 83-inch C4 will float your boat.

Again, it's the same but bigger, with a wider stand to support its ridiculous size. If you have a 'bigger is better' outlook on life, it's the TV for you.
