The 30-Second Version
The LG C5 77" delivers a world-class OLED picture and unbeatable gaming at a great price, but the Magic Remote and software hiccups keep it from perfection.
Overview
LG's OLED evo C5 series is their latest mid-range OLED for 2025, and the 77-inch model is a stunner for movie nights and gaming marathons. It's got that infinite contrast we all love, a silky 120Hz panel, and four full-bandwidth HDMI 2.1 ports, which is a dream for anyone with multiple consoles. But the Magic Remote and some WebOS update headaches keep this TV from being a no-brainer purchase.
Performance
Gaming is where the C5 truly flexes. Our database puts it in the 99th percentile for gaming performance, and it shows. With a 0.1ms response time, native G-SYNC compatibility, and FreeSync Premium, console and PC games feel ridiculously smooth. We were surprised that the picture quality percentile landed at just 36th, which seems off given the deep blacks and vibrant colors, but it likely reflects peak brightness limits against QLED rivals in our wider dataset. For dark room viewing, though, this OLED is a benchmark.
Pros & Cons
Pros
- Infinite contrast that OLEDs are famous for 99th
- Four HDMI 2.1 ports for all your next-gen gear 99th
- Superb gaming performance with 0.1ms response time 98th
- Evo panel gets brighter than older OLEDs 97th
Cons
- The Magic Remote is annoying and lacks a mute button
- Software updates can break apps or introduce lag
- Peak brightness still can't match top QLEDs for bright rooms
- No specific picture quality enhancement specs listed from LG

Value & Pricing
The price spread here is wild, from $1,579 all the way up to absurd five-figure listings. Stick to the low-end price around $1,579 at select retailers, and this 77-inch OLED is an absolute steal. For that money, you're getting class-leading gaming and contrast. It's worth every penny as long as you don't get stuck with the remote or a buggy update.
vs Competition
The Samsung S95F is the obvious rival, another 2025 OLED with perhaps a bit more brightness and a more traditional remote. Samsung's Tizen OS is snappier, too, if you value smart TV smoothness. But the S95F typically costs more. If you're willing to lose the pure OLED blacks but want higher brightness for a sunlit room, the TCL QM8K mini-LED is a killer value at similar sizes. For pure movie lovers in a dark room, the LG is still the best picture per dollar.

Common Questions
Q: Do all four HDMI ports support 4K 120Hz?
Yes, every one of them is full HDMI 2.1 with 48Gbps bandwidth, so connect your PS5, Xbox Series X, and PC all at once.
Q: How does the brightness hold up in a sunny room?
It's better than older OLEDs thanks to the evo panel, but still not as bright as a good QLED. In direct sunlight, you'll notice reflections.
Q: Is the 77-inch size worth the extra cost over 65 inches?
If your viewing distance is over 8 feet, absolutely. The immersion is a big step up, and the price premium is reasonable.
Who Should Skip This
If you primarily watch TV in a bright living room or can't stand quirky remote controls, skip the LG. The Samsung S95F has a cleaner interface and better brightness, and the TCL QM8K mini-LED is a brighter, cheaper alternative with less contrast but fewer frustrations.
Verdict
If you want a massive, beautiful OLED for gaming and movies, the LG C5 77" is an easy recommendation at its current street price. The picture quality is reference-level, and gaming performance is top-tier. Just know that you'll be wrestling with the remote and crossing your fingers with updates. For the price, it's a fantastic TV with a couple of fixable annoyances.
