The LG C3 OLED is one of the most anticipated TVs of the coming year — but it’s the LG G3 OLED that will have all the latest and greatest TV technology inside of it.

As it was explained to us at CES 2023, the LG G3 OLED will benefit from LG’s new Brightness Booster Max that uses a combination of the new Alpha a9 Gen 6 Processor and new lighting algorithm changes that boost the performance. The result, according to LG, is that the LG G3 OLED is about a 70% increase in brightness compared to older OLED TVs.

When deciding which of the two to buy in the coming year, there are two important factors to take into consideration: price and performance. The LG C3 OLED, like its predecessor the LG C2 OLED and LG C1 OLED, will be the cheaper option. However, the LG G3 will be the brighter of the two OLED TVs, which will be a big help in rooms with lots of ambient light.

We’re still waiting on final pricing information and a release date for both TVs, but based on the specs of the two TVs and the hands-on testing I did at CES 2023, I can give you a pretty good idea of what the differences will be and which one makes more sense for you.

LG C3 vs G3 OLED: price and screen sizes 

Since their inception a few years ago, the G-Series has always been the more expensive of LG’s two leading OLED TVs. Case in point: the 55-inch version of last year’s LG C2 OLED cost $1,799 at launch while the 55-inch LG G2 OLED came in at $2,199. Unless there’s some sort of major difference in the cost of production for 2023, I’d expect that you’ll be looking at nearly the same prices — and price differential — for this year’s models.

Obviously the lower price is a big advantage for the LG C3 OLED, but it’s not the only one — typically the C-Series is available in more sizes than the G-Series as well. Last year, the LG G2 came in five sizes: 55-inch, 65-inch, 77-inch, 83-inch and 97-inch models. The C2, however, came in all those sizes plus a 48-inch and 42-inch size. 

Without having confirmed release dates with LG, I can only speculate here, but based on everything I know and information from last year, I’m expecting the LG C3 OLED to be available in more screen sizes and lower price points than this year’s LG G3 OLED. 

LG C3 vs G3 OLED: design

So why pick an LG G3 OLED if it’s more expensive and comes in fewer sizes? The design and performance of the LG G3 are definitely its strong suits. 

New for this year, the LG G3 OLED comes with a no-gap wall mount that has been designed to sit exactly flush with the wall. In previous years, the TV might’ve stuck out a few centimeters, but this year it’s all about right up against the wall for maximum style.

The downside to the G3’s svelte new wall-mount is that the TV doesn’t come with a regular stand — instead it’s sold as an optional accessory that you have to purchase separately. The LG C3 OLED, on the other hand, comes with the stand but it’s not designed for the flush wall-mount. 

Outside of the way this TV looks when wall-mounted, both TVs offer the same amount of HDMI 2.1 ports (four) and all the same inputs and outputs. The LG G3 OLED will come with an ATSC 3.0 tuner inside that the LG C3 won’t have, so if being able to watch NextGen TV is important to you, then you should definitely opt for the G3 over the C3.

LG C3 OLED vs G3 OLED: Performance

As I mentioned earlier, better performance is another reason you might want to seriously consider the new LG G3 over the C3. Because it’s brighter, the LG G3 will definitely have more of a ‘wow’ factor than the C3 — its colors will pop a bit more and the extra brightness will help reduce the amount of screen glare from any ambient light in the room. 

The latter doesn’t sound important, but trust me, glare is probably the only issue I have with LG’s OLED TVs. It’s visible on every OLED TV LG makes and it can become a big problem if you’re someone who enjoys watching TV during daylight hours in a room with windows.

As far as upscaling and motion processing are concerned, both TVs should perform exactly the same — they share the same processor, after all — and I don’t expect there to be any problems with blooming, as each pixel produces its own light. 

Without having run the lab tests on them, I can’t give you specific numbers on how much better one is than the other, but just by looking at them side-by-side I was able to see the difference in the two models. The LG G3 feels like a huge upgrade on last year’s LG G2, while the C3 only feels like a minor upgrade on last year’s LG C2 — but those opinions could change when I get them in the lab for testing.

LG C3 OLED vs G3 OLED: which one should you buy? 

You should only buy a TV that aligns with your budget. As much as I love TVs, they’re costly investments and can really put a strain on your budget. If you’re looking for a cost-effective upgrade on whatever TV you own now, the LG C3 OLED looks like a great pick. That said, if money’s not a factor in your decision — or you’re in the position where you don’t mind spending a bit more for a better picture — then the LG G3 is worth keeping on your radar. The additional brightness, flush wall-mount and ATSC 3.0 tuner are substantial upgrades, and they do make the G3 feel like the more premium model of the two. We’ll of course update this article again once we have the TVs in for testing, but as of right now, the G3 has the C3 beat in everything but price and smaller screen sizes.
