Choosing among LG 4K TVs mostly comes down to two questions: which panel technology fits your room, and which size fits your wall and your seating distance. LG sells a Mini LED QNED line and an OLED evo line, and the gap between them is not just the panel. It shows up in black levels, viewing angles, processor generation, and how much of the lineup can handle high-refresh gaming. Once you settle the panel, the size decision is simpler than it looks.
This guide is for buyers who already want the LG brand, perhaps because of the webOS interface, an existing LG soundbar, or a gaming console that benefits from 4K at a high refresh rate. It walks through five models, from a 42-inch OLED that works as a big monitor to a 77-inch OLED for a dedicated movie room. Everything here comes from the specifications in the product titles, and the 2026 model year is the common thread.

How to Choose
Panel type: Mini LED versus OLED
An OLED pixel turns fully off, which is why the titles here highlight Perfect Black. That gives deep contrast in a dim room and wide viewing angles for a sofa that sits off to one side. Mini LED sets, like the QNED73B, rely on a backlight, so they reach high brightness in sunny rooms but cannot turn individual pixels off. If your room has big windows and you watch mostly in daytime, a bright LED-backlit set is a sensible tradeoff. If you watch movies at night, OLED is the stronger match.
Size and viewing distance
A common guideline is a screen about two-thirds as wide as your seating distance is deep, which works out to roughly a 55-inch set at 7 feet and a 65-inch set at 8 to 9 feet. A 77-inch screen suits viewing distances of 9 to 11 feet. The 42-inch model is meant for 3 to 5 feet, which makes it a TV for desks, bedrooms, and console gaming. Before you buy, measure the wall, the stand, and the room depth, and remember that a bigger OLED costs far more than a smaller one.
Processor and gaming features
The processor handles upscaling, motion, and tone mapping. The titles list an a7 AI Processor on the Mini LED set, an a11 on the 42-inch model, and Alpha 11 AI Processor Gen3 on the 77-inch. Newer generations generally manage upscaling of lower-resolution content more gracefully. For gaming, look for a stated 165Hz capability, as on the 77-inch listing, plus HDMI inputs that support 4K at high refresh. Check how many ports you have if you connect a console, a PC, and a soundbar.
HDR formats and sound
Dolby Vision and HDR10 appear in the titles, and Dolby Atmos support is listed on the 77-inch. Look for Dolby Vision if you stream, since many services use it. Built-in speakers on any slim TV are modest, so budget for a soundbar if movies matter. Ignore buzzwords such as “AI Super Upscaling” as deciding factors, and instead compare the panel type, the refresh rate, and the number of inputs.
Finally, think in budget tiers rather than exact numbers. The Mini LED 43-inch sits in the budget-to-mid range, the 42-inch and 55-inch OLEDs are mid-range to premium, and the 65-inch and 77-inch sets are firmly premium. Decide how much goes to the screen and how much to a soundbar or wall mount, since a great panel with weak sound or a wobbly stand wastes the purchase.
One caution about naming: the four C6 listings share a model family and differ mainly in screen size and the processor wording in each title. That means the size you choose matters more than any single feature, so decide the diagonal first and then check ports, stand design, and mounting holes against your furniture. It also helps to read whether the listing mentions a stand, since some sets ship with feet that are wider than expected.
The 5 Best Options
LG QNED73B 43-inch
This is the one for buyers who want a smaller LG screen without moving up to OLED. The title lists a 43-inch Mini LED 4K smart TV with the a7 AI Processor and Dynamic QNED Color.
- Strength: the Mini LED backlight is a better match for bright rooms than a dim-room OLED.
- Strength: the 43-inch size fits kitchens, dens, and guest rooms.
- Trade-off: It uses an older-tier a7 processor and cannot match OLED black levels in a dark room.
Skip it if you watch mostly at night or want high-refresh gaming features. Shoppers who want a second TV for a guest room or a kitchen counter are the natural audience, because the picture only needs to look good, not cinematic. Keep in mind that the title describes this as a 43-inch Mini LED set, so the value lies in brightness and size flexibility rather than in premium contrast.
LG OLED evo C6 55-inch
The 55-inch size is the practical center of the OLED lineup, and it suits apartments and mid-size living rooms. The title lists OLED evo AI, 4K, Brightness Booster, Perfect Black, and Perfect Color.
- Strength: the OLED panel provides pixel-level contrast for film and series.
- Strength: Brightness Booster is aimed at improving peak brightness over earlier OLED generations.
- Trade-off: OLED can still be dimmer than Mini LED in a sunny room.
Skip it if your viewing happens mostly in strong daylight, or if you want a screen larger than this for a big room. Renters and apartment dwellers often find 55 inches the sweet spot, since it fits a standard media console and does not dominate the room. The listed Brightness Booster is aimed at one of OLED’s historic weak points, so it deserves a close look if you watch with a few lamps on.
LG OLED evo C6 65-inch
Many families will land on the 65-inch screen because it balances immersion with a manageable footprint. It carries the same C6 features as the 55-inch: OLED evo AI, Brightness Booster, Perfect Black, and Perfect Color, with 4K smart TV functions.
- Strength: it fills the view for movie nights from a typical sofa distance.
- Strength: the OLED evo panel keeps shadows detailed instead of milky.
- Trade-off: Cost and weight compared with the 55-inch set, and wall mounting needs a sturdy bracket.
Skip it if your seating is under 6 feet from the screen, where this size can feel overwhelming. It is also the size where an OLED’s wide viewing angle pays off most, because a family spread across a sectional all sees consistent color. Plan for a stand or wall mount rated for the weight, and measure the shelf depth before you order.
LG OLED evo C6 77-inch
This is the choice for a home theater or a gamer with a console. The title lists Dolby Vision and Atmos, AI Super Upscaling 4K, HDR10, Filmmaker Mode, 165Hz gaming, and the Alpha 11 AI Processor Gen3.
- Strength: 165Hz support and the Alpha 11 Gen3 processor make it the most gaming-ready model here.
- Strength: Filmmaker Mode and Dolby Vision suit movie purists.
- Trade-off: Size and price, since 77 inches needs a large wall and a premium budget.
Skip it if your room is small or if you sit close to the screen. Buyers who pair it with a surround system will find the Dolby Atmos support a natural fit, and Filmmaker Mode helps keep movies close to the director’s intent. Measure doorways and the delivery path as well, because a 77-inch box is awkward to move through tight halls.
LG OLED evo C6 42-inch
The smallest OLED here is the one for people who want a big monitor on a desk or a bedroom screen. The title lists the OLED evo AI C6 with Perfect Black, Perfect Color, and the a11 AI Processor.
- Strength: the 42-inch size gives OLED contrast in tight spaces.
- Strength: the a11 processor sits above the a7 used on the Mini LED set.
- Trade-off: It is small for a living room, and the price per inch is higher than the larger sets.
Skip it if you want a shared family TV or sit more than 6 feet away. Console players who sit at a desk will appreciate that OLED contrast is not limited to big living-room sets. Check the stand width against your desk, and consider a monitor arm or wall mount if desk depth is shallow.
Which One Fits Your Situation
You have a bright living room
The LG QNED73B 43-inch uses a Mini LED backlight and is the logical match for a sunny space, though its small size suits a secondary room.
You watch movies at night with family
The LG OLED evo C6 65-inch gives deep blacks and wide viewing angles, so everyone on the sofa gets a good picture.
You play console games
The LG OLED evo C6 77-inch lists 165Hz gaming and a newer processor, while the 42-inch C6 is a good alternative if you play at a desk.
You are furnishing a small bedroom or a desk setup
The LG OLED evo C6 42-inch gives you OLED contrast at a size that fits a nightstand-height console or a desk, and its a11 processor is newer than the one in the Mini LED model.
Common Mistakes
- Buying the largest screen without measuring seating distance and wall space.
- Picking OLED for a room flooded with daylight and then finding reflections annoying.
- Relying on built-in speakers for movies instead of planning for a soundbar.
- Overlooking HDMI port count and refresh-rate support when connecting a console and a PC.
- Treating AI marketing labels as proof of better picture quality instead of comparing panel type and processor.

Frequently Asked Questions
Is OLED worth it over Mini LED?
For dark-room viewing, yes, because black levels and contrast are noticeably better. For bright rooms, Mini LED can be the more practical choice.
What size LG TV should I get?
Match the size to your seating distance: about 55 inches at 7 feet, 65 inches at 8 to 9 feet, and 77 inches beyond that. The 42-inch is for close viewing at a desk.
Do I need 165Hz?
Only if you game on a PC or a console that supports high refresh rates. For movies and streaming, a standard refresh rate is fine.
Will an OLED suffer burn-in?
Burn-in is possible with static images shown for very long periods, such as a news ticker left on all day. Varied viewing makes it unlikely, and the TV includes protective features, but avoid leaving a still image on screen for hours. Using the sleep timer and letting the TV run its built-in panel care routines is a simple habit that helps.
