7 things to know about LG's new C4 OLED TV

Key Takeaways

LG’s 2024 OLED lineup includes the popular LG C4 with improved AI processor for better performance and experience.
The LG C4 comes in sizes ranging from 42 to 83 inches, with prices starting at $1,500 to $5,400, offering options for various needs.
Some key upgrades of the LG C4 include a 144 Hz panel for smoother gaming, increased brightness, enhanced audio quality, and Google Chromecast support.

LG has formally announced its 2024 lineup of OLED TVs, including the LG C4. At the heart of the lineup, the C-series TVs have always been a good mix of features and price, which makes the TV one of the most popular models in LG’s OLED lineup. We loved the LG C3 when we reviewed it last year, and we expect the C4 to join the LG C3 on the list of some of the best smart TVs on the market.

The official release date for the new OLEDs is March 18th, 2024, which includes the LG C4. It’ll come in 42, 48, 55, 65, 77, and 83-inch variants with prices starting at $1,500 for the 42-inch and ranging up to $5,400 for the 83-inch. The models are now available for pre-order, but here are some other neat things you may want to know about the LG C4 before buying one.

1 It has a stronger processor than its predecessor

The LG C4 doesn’t house the most powerful, but it’s an improvement

The LG C3 came with LG’s Alpha 9 AI Processor Gen6, often written as the a9 Gen6. It’s a perfectly serviceable processor, but the LG C4 will do slightly better. It sports an upgraded version of the Alpha 9 AI Processor, which LG says will improve performance across the TV.

While more testing is needed, the upgraded chipset should allow for faster WebOS interaction, better upscaling, and improved motion handling from the LG C3.

Only the LG G4 and M4 will sport a stronger processor along with a lot of the new AI features that LG brought to the show this year, which house the top-of-the-line Alpha 11 AI Processor, otherwise known as the a11. The a11 boasts significant speed improvements over the prior generation, according to LG. While the C4 misses out on the highest-end performance, its upgraded a9 processor will still make the experience better.

2 The panel will run at 4K and 144 Hz

The upgraded processor bears another improvement that is important enough to mention in its own right. The LG C4 will run at 144 Hz, which is an upgrade over the LG C3’s 120 Hz. It’s true that the Xbox Series X and PlayStation 5 won’t be able to take advantage of the higher refresh rates. However, enterprising PC users who want to use the OLED TV as their monitor most certainly can, and it’ll be a smoother desktop experience than older LG OLED TVs.

The improvement is strictly because of the upgraded processor as the LG C4 otherwise has the same panel as the LG C3. That means all the improvements are coming from within rather than without. In addition, the C4 will come with AMD FreeSync along with full Nvidia G-Sync VRR certification. The latter is an upgrade over the LG C3.

3 The LG C4 is brighter and more colorful than its predecessor

LG hasn’t released specifics, but the C4 will be brighter than the C3

During CES 2024, LG’s David Seperson told What HiFi that “all of the C4s will get brighter this year than they were last year.” In addition, the 42-inch and 48-inch models, which are generally less bright than their larger siblings, will get an even larger bump in brightness to make them more equal to the rest of the lineup.

Thus, it doesn’t matter which size you look for, it’ll be brighter than it was last year, which is surprising considering that the MLA display technology that makes the LG G3 so much brighter than the C3 didn’t trickle down to LG’s C-series TVs this year as some pundits originally expected. The difference isn’t massive, but considering that the C3 is still best used in darker rooms, a boost in brightness might help change that for the C4. Perhaps 2025 will see MLA technology dip down into the middle tier of LG’s OLED lineup.

4 The LG C4 should sound better than the LG C3

Sound quality was one of our biggest nitpicks of the C3

Pocket-lint

When we reviewed the LG C3, sound quality was one of the biggest detractors, and we weren’t the only ones who thought so. LG appears to be listening as the LG C4 is getting some audio upgrades as well. The older C3 has virtual 9.1.2 surround sound and some rather dull sounding speakers.

Meanwhile, the LG C4 is coming with 11.1.2 sound upmixing along with enhanced voice remastering for better dialog clarity.

Sound demos weren’t available at LG’s booth, but with the improved upmixing capabilities, we’re hoping that translates to better sound coming out of the TV’s default speakers as well.

5 All of LG’s 2024 OLEDs will be Google Home hubs with Chromecasts built-in

LG partnered with Google for more steamlined streaming

Pocket-lint

At one point during LG’s presentation, they brought Google out on stage where they announced Google Chromecast support for LG’s entire 2024 TV lineup, including the LG C4. It’ll work the same way it does on Google TV and the existing Chromecast. Users will be able to hit the icon, select their LG C4, and cast straight to the TV.

Why you should use a Chromecast for all your streaming and casting

You can turn any TV into a smart TV with Google’s own dongle. It’s inexpensive, has a full UI, and lets you stream, cast, and more.

It’s part of a partnership that is bringing more Google features to LG products, including Google Home and Matter support. LG TVs will soon act as Google Home hubs where you can set up and control smart home devices through LG’s ThinQ app.

The C4 won’t have the smart home features at launch, but it should roll out later in 2024.

6 The C4 will be among the first to use Dolby Vision Filmmaker Mode

TVs have had HDR of various types for years, including HDR10, Dolby Vision, and others. LG is taking it a step further in 2024 with the introduction of the Dolby Vision Filmmaker Mode. For the uninitiated, LG introduced regular Filmmaker Mode a few years ago. It’s a picture mode developed by the UHD Alliance to make movies look better by either enabling or disabling specific TV features to preserve the director’s original vision.

Whether you lost your remote or want a more streamlined navigation experience, using your phone to control your Roku TV is a game-changer.

Dolby Vision Filmmaker Mode is essentially the same thing but for HDR. It’ll disable motion smoothing, keep artificial sharpening to a minimum, and set the TV to a warmer color temperature to recreate the look viewers can see in movie theaters.

If it’s anything like regular Filmmaker Mode, it’ll also subtly reduce the brightness to avoid highlight blowouts in brighter scenes.

7 The LG C4 will be compatible with LG’s wireless sound bars

All wireless home theater setups are getting closer and closer to reality. The LG C4, G4, and M4 are one step closer to that reality than many other TVs. All three come with the ability to connect wirelessly to LG’s S95TR and SG10TY and process wireless, lossless Dolby Atmos sound. That means you won’t have to waste your eARC HDMI port to get your soundbar up and running.
