You're standing in the middle of a Best Buy or scrolling through endless Reddit threads, and it hits you. There are too many options. But the LG OLED C4 55 keeps popping up like that one song you can't get out of your head. Is it actually better than the C3, or is LG just shuffling the deck chairs? Honestly, it’s a bit of both, but for most people, the 55-inch C4 is basically the "Goldilocks" zone of home cinema right now.
The 55-inch frame isn't just a random number. It's the size where 4K density actually looks sharp enough to cut glass without requiring a living room the size of a hangar. If you sit six feet away, it’s immersive. Seven feet? Still great. It’s versatile.
What’s actually under the hood this year?
LG didn't reinvent the wheel with the C4. They just polished it until it blinded the neighbors. The big talking point is the Alpha 9 AI Processor Gen7. Marketing fluff? Mostly. But it does a weirdly good job at upscaling that grainy 1080p footage of The Office you’ve seen a thousand times. It looks cleaner. The colors pop without looking like a neon sign in a basement.
Brightness has always been the OLED Achilles' heel. If you have a sun-drenched living room, you’ve probably heard people scream "get a Mini-LED!" But the C4 fights back. LG boosted the Peak Brightness Booster algorithm. It's not reaching G4 levels of "melt your retinas," but it's noticeably punchier than the older B-series or even the entry-level OLEDs from a few years ago.

You get 144Hz now. That’s the big win for the PC crowd. If you’re hooking up a rig with an RTX 4090, the LG OLED C4 55 acts more like a giant gaming monitor than a TV. It’s buttery. Console players on PS5 or Xbox Series X are still capped at 120Hz by the hardware, but having that 144Hz ceiling means this thing is future-proofed for the next wave of GPUs.
Gaming is where it gets aggressive
Input lag is basically non-existent. We’re talking sub-10ms. When you press a button in Elden Ring, you die instantly because of your own mistakes, not because the TV was lagging. It’s brutal honesty in pixel form.
The Game Optimizer menu remains the best in the business. It gives you a HUD that looks like something out of a fighter jet. You can toggle VRR (Variable Refresh Rate), G-Sync, and FreeSync Premium Pro. LG didn't cut corners on the ports either. All four HDMI ports are full-bandwidth HDMI 2.1. This sounds like technical jargon, but it’s actually huge. Most mid-range TVs from Sony or Hisense only give you two high-speed ports, and one of those is usually taken up by your soundbar (eARC). With the C4, you don't have to play musical chairs with your cables.

The "Green Tint" and other OLED myths
Let’s talk about the elephant in the room: burn-in. People act like an OLED will explode if you leave the news on for an hour. It won’t. Modern panels, especially the WOLED tech LG uses in the C4, have so many software safeguards that you'd have to actively try to ruin it. Pixel cleaning, screen shift, and logo luminance adjustment work in the background. Unless you’re running a sports bar with a static ticker 24/7, you're fine.
Then there’s the off-angle viewing. This is where the LG OLED C4 55 absolutely dunks on LED TVs. If you’re sitting on the "bad" end of the couch during family movie night, the colors don't wash out. Contrast stays perfect. The blacks are actually black—not that murky grey-blue you see on cheaper screens when the room gets dark.
Comparing the 55-inch C4 to the competition
Sony’s Bravia 8 is the main rival. Sony has better motion processing—it’s just a fact. Movies look a bit more "filmic" on a Sony. But you pay a massive premium for it, and you lose half your high-speed HDMI ports. For most people, that trade-off isn't worth it. Samsung’s S90D is another beast. It uses QD-OLED, which gets more colorful in bright scenes, but it lacks Dolby Vision. If you’re a Netflix or Disney+ power user, losing Dolby Vision feels like a step backward. LG supports it fully.

Why 55 inches is the sweet spot
- Pixel Density: At 55 inches, 4K resolution (3840 x 2160) results in about 80 pixels per inch. It's incredibly crisp.
- Price to Performance: The jump from 55 to 65 inches often costs an extra $500 to $800. Is ten inches of diagonal space worth that? For most bedrooms or small apartments, definitely not.
- Weight: You can actually mount this by yourself if you're feeling brave (though maybe get a friend). It’s thin. Scary thin. Like a wafer.
The sound is... fine. It's a flat-screen TV. Physics dictates that tiny speakers in a thin chassis will never sound like a cinema. It uses AI Sound Pro to "virtualize" a 9.1.2 surround setup, but let's be real: it’s thin. Buy a soundbar. Even a cheap one will outperform the built-in speakers.
Is it worth the upgrade from a C2 or C3?
If you have a C3, stay put. The differences are incremental. You get a slightly faster chip and the 144Hz bump. It’s not enough to justify the hassle of selling your old set. But if you’re coming from a C1 or an older LED TV? The jump is massive. The brightness alone will make your old TV look like it was covered in a layer of dust.
WebOS has also matured. It’s less cluttered than it used to be. You get "Quick Cards" to jump into gaming, music, or home office setups. It also supports Chromecast built-in now, which was a weird omission for years. Finally, Android and iPhone users can cast stuff without jumping through hoops.
Actionable steps for your new LG C4
If you decide to pull the trigger on the LG OLED C4 55, don't just leave it on the "Vivid" setting. It looks terrible and makes everyone look like they have a sunburn. Switch to Filmmaker Mode for movies—it turns off all the "soap opera effect" motion smoothing and sets the white balance to the D65 standard that directors actually use. For gaming, make sure you toggle HGiG in the HDR settings; it lets the console handle the tone mapping instead of the TV, which prevents your highlights from getting blown out. Lastly, check your room lighting. OLEDs thrive in light-controlled environments. If you have a massive window directly opposite the screen, grab some blackout curtains to really see what those perfect blacks can do.
