Best LG TV 2025: The best 4K and 8K TVs

We found the C3 OLED to be a slight disappointment, but the latest mid-range screen in the C4 OLED is more in line with what we expect from the Korean company.

While there’s no MLA boosting brightness tech that’s present on the LG G4, the C4’s picture quality produces more intensity with HDR highlights than the previous model, with colours that look rich and lush but never overstated. Its motion processing is better too, with less judder and artifacts in general.

The 2024 webOS interface is slick to use, introducing user profiles to customise content for each person, and there’s a guarantee of security updates for the next five years. It’s responsive, and easy enough to navigate. In terms of streaming apps it has as many as you would ever need to use.

Much like previous LG C-series OLEDs, the C4 features four HDMI inputs, but an upgrade for 2024 was that refresh rates were boosted to 4K/144Hz high frame rates, along with support for ALLM, and VRR. There’s also support for Nvidia and AMD VRR too. We measured input lag at 13ms, but with Boost mode enabled that can go down to 9ms.

The audio system is the one area that we find rather average. The AI sound mode raising the noise floor when selected so you’ll want to add a soundbar to this system to get the best performance.

Strangely, even though the OLED65G3 exhibited a slight green tint, the OLED77G3 didn’t have the issue. In fact, it features a red push to images but aside from that it delivers hugely impressive picture quality on a big scale. Contrast is fantastic with deep blacks and the screen’s high peak brightness combining to deliver a lovely looking image.

The audio performance isn’t the G3’s strong suit with the low-end lacking punch and intensity. However, dialogue intelligibility is good with the speakers striking a natural tone and the placement of voices echoing where people are on screen.

LG’s webOS interface is slick and swift, and when it comes to content there’s support for Netflix, Prime Video, Disney+, Apple TV+, NOW and more, along with Freeview Play that comes with the UK catch-up apps.

The OLED77G3 includes four HDMI 2.1 ports and a range of wireless connectivity options that includes Wi-Fi, AirPlay 2, Chromecast, WiSA, Bluetooth 5.0, and Bluetooth Surround Ready. Gamers benefit ALLM, VRR and 4K/120Hz support across all HDMI inputs. There’s also AMD FreeSync Premium and Nvidia G-Sync for PC gamers, along with a variety of cloud gaming and broadcasting services, including GeForce Now, Utomik, Blacknut, and Twitch.

The OLED77G3 is still available but is starting to go out of stock at some retailers. You may want to consider the newer OLED77G4 as that is only slightly more expensive than this model, but we’ve not reviewed the latest version.

After a slightly lacklustre G3 OLED, LG was back on form with its G4 OLED, though it doesn’t resolve all of its predecessors problems.

The picture performance is almost brilliant if it weren’t for a slight green tint affecting the TV’s film modes. It’s not as noticeable in the content we use to test as it was on the G3 OLED, but in terms of an accurate image out of the box, the G4 OLED isn’t where we think it should be for the price.

But aside from the issue, the LG G4 OLED boasts a generally excellent image. It hits a very high level of brightness for an OLED TV, hitting 1523 nits on a 2% window, while full screen brightness is 287 nits. That level of brightness feeds into the LG’s rich and balanced looking image, the new processing features provide depth to images, and the motion processing is clearer and more detailed. Upscaling lower than 4K resolution offers impressive levels of detail, clarity, and sharpness without seeming artificial or unnatural.

The audio performance sounds warmer and weightier with a bit more bass. We found the LG G4 OLED to be excellent at handling dialogue, making sure it’s audible with all types of content. The AI Sound Pro mode is good with Dolby Atmos tracks but still sounds too sharp with live broadcast streams. We’d still like some more dynamism and intensity to the sound system but it is a better sounding unit than the LG C4.

WebOS is home to Freeview Play and all the UK catch-up and on-demand apps, with plenty of other choices from video to sports and music to choose from. It’s an intutive interface although since we reviewed the TV there’s been an increasing amount of ads on the interface.

Gaming has always been a strength of LG’s OLEDs and there’s support for 4K/144Hz, VRR and ALLM across all the HDMI inputs, with VRR covering HDMI VRR, AMD FreeSync Pro and Nvidia G-Sync. We measured latency at 12.9ms, which is par for the course with LG OLEDs.

If it weren’t for the slight green tint we noticed, we’d rate the LG G4 as not only one of LG’s best TVs but one of the best TVs of 2024. Until it can resolve the picture issue, it’ll have to settle for being a very good OLED TV.

The OLED77Z3 is an even more expensive proposition than its predecessor at £14,999, but at least the jump in price results in visible picture quality improvements.

Compared to its Z2 predecessor, peak brightness hits above the 1000 nit mark, and black levels are inky deep, offering impressive contrast out of the box. Although its levels of sharpness aren’t as great as we’d like, the scale of its images is a sight to beyond.

While motion processing on its 4K TVs has improved year-on-year, we do feel the performance could be improved with issues such as judder in some of the modes.

The smart experience offers a wide range of apps to enjoy, lots of connectivity options and cloud gaming apps such as Nvidia GeForce NOW. On the gaming front there’s Dolby Vision gaming (with Xbox Series consoles) as well as 4K/120Hz, 8K/60Hz, VRR and ALLM across all HDMI inputs. Input lag at 13.6ms, which is slower than LG’s 4K TVs, but that’s down to the increase in resolution to 8K.

One area where the Z3 isn’t as good as its predecessor is with sound system which is affected by distorted bass. It offers good levels of clarity and detail, but for images as good as this, you’d be better off with a soundbar.
