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

The C4 is pretty long in the tooth now, having first launched in the spring of 2024, but it's still available from various retailers.

In truth, at this point, it generally makes more sense to go for the newer C5, which has also now been heavily discounted, but you might find that you can pick up a C4 for even less.

This page is where you will find the best C4 deals available anywhere on the internet. Find the size you're after, compare it with the C5 prices on our best LG C5 deals page, and make the call on which one to buy.

My personal advice is that if the C5 is only 10-15 per cent more expensive than the equivalent C4, it's the newer model you should go for.

The difference in performance is fairly small (very small with the 42- and 48-inch versions), but it is there and worth a little extra money. Check out our LG C5 vs C4 page for the full comparison.

What about the new C6, which was just announced at CES 2026?

It looks very impressive, with a big processor upgrade across the board and a huge panel upgrade (from WOLED to Primary RGB Tandem OLED) for the 77- and 83-inch versions, but it will be months until you'll be able to buy one, and it will be monstrously expensive at launch.

Unless you're prepared to wait for the C6 to drop significantly (likely to happen around November), your better bet is to pick up a C4 or C5.

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.

The 42-inch C5 is only a very slight upgrade on this C4, so if this is cheaper, go for it.

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 is generally incredibly detailed.

As with the 42-inch models, the upgrade from the 48-inch C4 to the 48-inch C5 is minor, so buy this older model if it's a bit cheaper.

LG OLED55C4 (55-inch)

Launch price: £1900 / $1999 / AU$3299

Once you hit 55 inches, OLED panels get brighter, which improves contrast, dynamism and effectiveness in a bright room.

Other than that, you get the same excellent picture quality that the smaller sets deliver, but at a larger, more cinematically exciting size.

Do bear in mind that this is also the size where the gap between the C4 and newer C5 widens, so if the price difference is relatively small, it makes sense to go for the C5.

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 combine with a more natural authenticity to create stunningly lifelike images.

Just remember that the C5 is another step forward, so buy the newer model if pricing is close.

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.
