You're standing in the middle of a Best Buy or scrolling through endless Amazon listings, and it hits you. Every single screen looks exactly the same. But then you see it—the 65 inch LG 4K TV lineup. It’s not just a size; it’s basically the industry standard for "I want a theater but I don't want to rearrange my entire life."
Honestly, picking a TV used to be simpler when we just argued about plasma versus LCD. Now, LG has complicated things by being really, really good at several different technologies at once.
Most people think bigger is always better. That’s a lie. If you cram an 85-inch screen into a small apartment, you’re basically watching pixels, not a movie. A 65-inch screen hits that perfect middle ground where 4K resolution actually makes sense. At this size, the pixel density is tight enough that you can sit six feet away and not see the "screen door" effect, but it's large enough to actually feel the impact of a 4K Dolby Vision master.
The OLED vs. QNED Confusion
LG basically owns the OLED market. They make the panels for almost everyone else, too. If you’re looking at a 65 inch LG 4K TV, you’re likely choosing between their C-series OLEDs (like the C3 or C4) or their QNED models.
OLED is the king of "true black." Because each pixel turns off individually, a space scene looks like actual space, not a gray, foggy mess. It’s transformative. You've probably heard people rave about it, and yeah, the hype is real. However, OLEDs aren't perfect. They don't get as screamingly bright as Mini-LED sets. If your living room has giant floor-to-ceiling windows and you live in a sunny place like Phoenix, an OLED might struggle against the afternoon glare.
That’s where QNED comes in. It uses Quantum Dots and NanoCell technology with a backlight. It’s bright. Like, "hurt your eyes in a dark room" bright. For a lot of families who keep the lights on while watching Bluey or the game, the QNED 65-inch models are actually the more practical choice, even if the "purists" on Reddit say otherwise.
Gaming is the secret reason LG wins
LG's dominance isn't just about movies. It's the gamers.

If you hook up a PS5 or an Xbox Series X to a 65 inch LG 4K TV, especially the OLED models, the experience changes. Most TVs have "Game Mode," but LG went a step further with their "Game Optimizer" menu. It gives you a real-time HUD showing your frames per second (FPS) and VRR (Variable Refresh Rate) status.
Low latency is everything. LG’s high-end 65-inch sets often boast an input lag of under 10 milliseconds. To put that in perspective, that’s faster than the human blink. It feels instantaneous. When you pull the trigger in Call of Duty or parry in Elden Ring, it happens right then. No delay.
What most reviewers don't tell you about webOS
Everyone talks about the screen, but you’re going to spend half your life interacting with the remote. LG uses the "Magic Remote." It works like a Nintendo Wii pointer. You shake it, a cursor appears on the screen, and you point at what you want.
Some people hate it.
I’ve seen friends get visibly frustrated trying to click a tiny search bar while the cursor flies around. But once you get the muscle memory down, it’s significantly faster than clicking a D-pad a hundred times to type "Netflix." Also, webOS—the software inside the TV—has become a bit "ad-heavy" lately. You'll see recommendations for shows you don't care about and apps you'll never download. It's the price we pay for hardware that is subsidized by software partnerships. You can't really escape it anymore, regardless of the brand.
The 4K resolution myth at 65 inches
Let’s be real for a second. 4K is 3840 x 2160 pixels. On a 43-inch TV, you can barely tell the difference between 1080p and 4K unless your face is pressed against the glass. On a 65 inch LG 4K TV, the math changes.

At 65 inches, the screen is large enough that the extra detail in 4K actually matters. You can see the individual blades of grass on a football field. You can see the texture of the fabric on a character's suit. But here is the catch: your content has to be 4K too. If you’re watching old reruns of The Office on a non-HD cable box, the TV has to "upscale" that image. LG’s Alpha 9 and Alpha 7 processors are some of the best at this. They use AI to guess what those missing pixels should look like. It’s not magic, but it’s close. It makes 1080p content look "4K-ish," which is better than it looking blurry and stretched.
Mounting this beast
A 65-inch TV isn't light. An LG C3 in this size weighs about 36 pounds without the stand. That’s manageable for one person if you’re careful, but for the love of everything, get a friend to help you.
The VESA mount interface on most LG 65-inch sets is standard (usually 300x200 or 300x300), but the placement is often low on the back of the panel. This means if you're replacing an old 65-inch TV, your existing wall mount might make the LG sit way higher or lower than your old one. Measure twice. Seriously.
Also, cables. If you’re spending the money on a 65 inch LG 4K TV, don't use that HDMI cable you found in a junk drawer from 2012. You need an Ultra High Speed HDMI 2.1 cable to actually get 4K at 120Hz. If you don't use the right cable, you're literally leaving performance on the table.
Sound quality is... fine
Thin TVs have thin speakers. It’s physics.
LG tries to solve this with "AI Sound Pro," which attempts to virtualize a 9.1.2 surround sound experience from two little speakers pointing downward. It’s okay for the news. It sucks for Interstellar. If you're buying a TV of this caliber, factor in the cost of a soundbar. LG’s own soundbars have a feature called "WOW Orchestra" where the TV speakers and the soundbar work together simultaneously. It’s a neat trick that makes the soundstage feel taller.

The longevity question: Burn-in and lifespan
The "B-word." Burn-in.
People worry that if they leave CNN or a video game HUD on their 65 inch LG 4K TV for too long, the image will permanently ghost onto the screen. In 2026, this is mostly a ghost story itself. Modern LG OLEDs have "Pixel Cleaning" and "Screen Move" features that shift the image by a few pixels every now and then to prevent uneven wear. Unless you are running a sports bar that plays the same channel 24/7 at max brightness, your TV will likely be obsolete before it burns in.
Getting the most out of your purchase
Don't just take it out of the box and leave it on "Vivid" mode. Vivid mode is a lie. It makes colors look like neon candy and turns skin tones into orange clay.
Switch it to "Filmmaker Mode" or "ISF Expert." It will look "yellow" or "dim" for the first five minutes because your eyes are used to the blue-light-blasting factory settings. Give it a day. You'll start to notice details in the shadows that were previously blown out. You'll see colors as the director intended.
Next Steps for New Owners:
- Check your HDMI settings: Ensure "HDMI Deep Color" is turned on for all ports in the settings menu, or your HDR won't work correctly.
- Turn off Motion Smoothing: LG calls it "TruMotion." Unless you want your favorite cinematic movie to look like a cheap daytime soap opera, turn this off immediately.
- Update the Firmware: Out of the box, the software is likely months old. Connect to Wi-Fi and run the update to get the latest image processing tweaks.
- Test for "Dead Pixels": Pull up a solid white or solid red YouTube video and look closely at the screen to make sure every pixel is firing. It’s better to find a defect in the first 30 days while the return window is open.
A 65 inch LG 4K TV is a significant investment, but it's the specific point where high-end technology finally feels "worth it" for the average person. You get the size, you get the clarity, and if you go OLED, you get the best picture quality currently available to humans. Just remember to buy a decent HDMI 2.1 cable.
