LG CX still dazzles, but C4 is brighter, faster, and more future‑proof.
You’re choosing between a proven classic and a shiny upgrade. That was my exact dilemma with the lg cx vs c4 in my living room. Both look stunning at night, but daytime glare and gaming needs pushed me to test them side by side. I’ve spent weeks watching movies, streaming sports, and gaming on both. Below, I’ll share what actually matters so you can pick the right one for your space and habits.
Is LG CX Good?
The short answer: yes, especially if you value pure OLED contrast and great gaming for less money. The LG CX still delivers deep blacks, rich color, and four HDMI 2.1 ports. It is ideal for movie lovers and console gamers who don’t need 144Hz or the latest webOS features. If you can find it at a good price, it’s a smart buy.
I’ve used the CX as a main TV and as a temporary PC monitor for a week. Nighttime movies in Dolby Vision still look cinematic. My PS5 sessions ran smooth at 4K/120, and input lag never got in the way. In a bright room, I noticed the C4’s extra punch, but the CX held up well with blinds drawn.
What Makes It Stand Out / Key Features
- 4K OLED panel with perfect blacks and wide viewing angles
- α9 Gen 3 Processor 4K for clean upscaling and motion
- 4x HDMI 2.1 with 4K/120, VRR, and ALLM support
- Dolby Vision and Dolby Atmos support with eARC
- Game Optimizer-style tools (via updates) and G-Sync/FreeSync compatibility
What I Like
- Gorgeous contrast that still rivals newer sets at night
- Strong gaming chops with smooth 4K/120 and low input lag
- Natural, filmic image for movies and prestige TV
- Excellent upscaling of HD cable and older Blu-rays
- Often far cheaper on the used/refurb market
What Could Be Better
- Lower peak brightness than newer OLED evo panels
- Older webOS experience and fewer new feature updates
- No 144Hz support for high-frame-rate PC gaming
- As with any OLED, be mindful of static logos to reduce burn-in risk
My Recommendation
If you want top-tier OLED for less and don’t need 144Hz or the newest OS, the LG CX is still a fantastic choice.
| Best For | Why |
|---|---|
| Movie lovers on a budget | Elite contrast and cinematic tone for less money |
| Console gamers | 4K/120, VRR, and low input lag cover PS5 and Xbox needs |
| Dark-room viewing | Blacks and shadow detail remain exceptional |
Is LG C4 Good?
Yes. The LG C4 is the better all-rounder for most buyers today. It’s brighter, snappier, and more gamer-friendly, especially if you play on a high-end PC. The OLED evo panel boosts punch in daylight. The newer processor and webOS 24 make it feel fast and current for years.
In my tests, sports looked cleaner with less blur, and HDR highlights had more “pop” in a sunny room. I pushed 144Hz from a PC and noticed the extra fluidity in shooters. Dolby Vision movies still looked lush at night, but the C4’s added brightness helped retain specular detail in daytime scenes where the CX would dim sooner.
What Makes It Stand Out / Key Features
- OLED evo panel with improved brightness and efficiency
- α9 AI Processor 4K (Gen7) for cleaner motion and upscaling
- Up to 144Hz support, plus VRR/G-Sync/FreeSync Premium
- webOS 24 with multi-year feature updates and profiles
- Dolby Vision/Atmos, eARC, Game Optimizer dashboard
What I Like
- Noticeably brighter HDR and better ABL handling in real scenes
- 144Hz is a win for PC gamers and high-FPS titles
- Faster menus and smarter recommendations in webOS 24
- Refined motion handling for sports and action films
- Future-ready connectivity across all four HDMI 2.1 ports
What Could Be Better
- Costs more than older OLEDs like the CX
- Still not as bright as the flagship tier in very sunny rooms
- Built-in speakers are fine, but a soundbar elevates the experience
My Recommendation
If you want a bright, modern OLED with long-term support and top-notch gaming, the LG C4 is the safer buy.
| Best For | Why |
|---|---|
| Mixed rooms and daytime viewing | Brighter panel keeps highlights visible in sunlit spaces |
| PC and console gamers | 144Hz, VRR, and low lag offer elite smoothness |
| Smart TV users | webOS 24 is fast, clean, and gets long-term updates |
