Having reviewed many OLED TVs over the years, I feel uniquely qualified to help, especially when comparing two popular models: theLG C3andLG C4.

Both OLED TVs are getting discounts for Prime Day. In the US, the65-inch LG C3 is $1,396 (was $1,499)and the65-inch LG C4 is $1,796 (was $2,699), while in the UK, the65-inch LG C3 is £1,349 (was $1,549)and the65-inch LG C4 is £2,289 (was £2,699).

The C3 is clearly the cheaper option – not surprising given that it’s a 2023 model and the C4 is new for 2024. So, you will save money by buying LG’s 2023 mid-range OLED, but will the savings be worth it? Read on to find out.

Today’s best LG C3 OLED TV deals (UK)

LG C3 65-inch OLED TV:was £1,549 now£1,349 at AmazonThe LG C3 is a jack-of-all-trades TV with excellent picture quality, great gaming capabilities, and performance. We’ve picked the 65-inch model here as it’s ideal for almost any environment and situation, be it watching movies, streaming Netflix, or gaming on current-generation consoles. Amazon’s deal brought the price down to a record-low price of £1,349, and this price equates to a tasty saving on a very popular model.

LG C4 65-inch OLED 4K TV:was £2,699 now£2,289 at AmazonThe latest mid-range OLED TV from LG, the LG C4, is now available for £2,289 at Amazon. The 65-inch TV features exceptional brightness, premium sound, and impressive gaming features, including four HDMI 2.1 ports with 4K 120Hz, VRR, and ALLM support and 144Hz certification from Nvidia.

The new LG C4 offers a few key features not found on the LG C3. The main one is a new Alpha 9 AI Gen7 processor with improved 4K picture upscaling and a Brightness Booster feature. In my C4 testing, this feature worked as advertised. It provided a modest yet notable brightness increase over the C3, boosting peak brightness past the 1,000 nits threshold that earlier OLED TVs, the C3 included, struggled to achieve.

The LG C4 also features a newDolby Vision Filmmaker Modethat provides a director-approved picture out-of-the-box when watching movies and TV shows with Dolby Vision HDR. LG OLED TVs for 2024 are the first to feature this mode, eliminating the motion smoothing that Dolby Vision modes on TVs typically add to the picture. Disabling it requires a visit to the setup menu.

LG TVs, including the C3 OLED, rank among thebest gaming TVswith four HDMI 2.1 ports with 4K 120Hz support, VRR, and ALLM. The C4 ups the ante by adding Nvidia-certified 144Hz support for PC gaming. It also gets a sound quality boost over the LG C3, with the ability to mix sound to virtual 9.1.2-channel Dolby Atmos over its 2.2-channel built-in speakers (the C3, in contrast, topped off at 7.1.2 channels).

Do these enhancements add up to a win for the LG C4 over the LG C3 OLED? Having lived with both TVs for a time, I appreciated theC4’sbrightness increase, which made highlights in movies and TV shows with HDR better pop off the screen, giving the picture a more 3D-like quality. That said, theC3is also a great TV, and looking back at my review, I found its “brightness to be perfectly adequate even for daytime viewing, and with lights dimmed, the picture had notably punchy contrast.”

That’s not bad for a 65-inch OLED TV selling for $1,796 / £1,349, but if I were to choose between the two, I’d opt for the slightly more expensive C4 with its enhanced brightness and other picture and sound-improving features.
