Choosing a new TV for a small living room, bedroom, or kitchen always requires a thorough analysis of specifications, especially when the diagonal size is limited to 43 inches. This segment is witnessing a fierce battle between two Korean giants: Samsung And LGBoth manufacturers offer advanced technologies. Smart TV and built-in modules Wi-Fi, but their approaches to image quality and interface differ radically. It's often difficult for buyers to determine which system will be more convenient and which sensor will provide the best picture in low light.
In this article, we'll delve into the technical details behind the series' catchy names. You'll learn about the differences in operating systems, backlight types, and support for modern HDR standards. It is important to understandThat choosing between these brands isn't just a logo choice, but a choice of the ecosystem you'll interact with daily. We'll help you weigh the pros and cons to make an informed decision.
The modern electronics market dictates its own rules: simply having a high-resolution screen isn't enough. A fast interface response, support for all popular apps, and a stable wireless connection are essential. We'll focus on these aspects when comparing 43-inch models, which remain the "golden mean" for most apartments.
Operating Systems: Tizen vs. webOS
The first thing the user encounters after turning on the TV is the interface. Samsung a proprietary system is installed Tizen OSIt features a minimalist design and an app drawer that slides out from the bottom of the screen. This keeps content visible while you scroll through the menu. The system runs smoothly, but its closed architecture limits the installation of third-party apps not from the official store.
Company LG uses the platform webOSIts key feature is the launcher, which also appears at the bottom but has a more flexible window structure. Many users note that webOS is slightly faster to navigate, especially on mid-range models. However, there are still limitations to installing APK files directly, as on Android TV.
Both systems support major streaming services such as YouTube, Netflix, and Kinopoisk. However, the management approach differs. Tizen relies on a classic remote control with buttons, whereas webOS often comes with a remote control Magic Remote with a cursor controlled by hand movement, similar to working with a computer mouse.
- 🖱️ Control: LG offers cursor control (Magic Remote), Samsung - classic buttons and a touchpad.
- 📱 Mobile application: Both brands have excellent smartphone apps, but LG ThinQ's integration is often deeper.
- 🎮 Game services: Samsung is actively promoting its gaming hub, while LG is betting on support for GeForce Now and Google Stadia (where available).
⚠️ Please note: System interfaces are updated regularly. The menu layout in new 2026-2027 models may differ from previous versions, so it's worth checking out up-to-date interface reviews online before purchasing.
Matrix quality and backlight technology
In a 43-inch diagonal, manufacturers most often use matrices of the type VA or IPS, and here lies the main difference in the brand philosophy. Samsung Most models (CU, AU series) use VA matrices. Their main advantage is a high contrast ratio and deep blacks, which are ideal for watching movies in a darkened room.
LG Traditionally, IPS panels are preferred (although there are exceptions in the 43-inch size). IPS panels are renowned for their wide viewing angles: if you watch the TV from the side, colors don't fade. However, they have lower contrast, and blacks in dark environments can have a grayish tint, which is noticeable when viewing HDR content.
Both manufacturers are actively implementing image enhancement technologies. For Samsung, it's a processor. Crystal Processor, which upscales the image to 4K. LG uses a chip α (Alpha) Processor or its simplified versions, which also effectively remove noise and improve motion clarity. For gamers, the refresh rate remains an important parameter: 60 Hz is most common in this size, but top-end models can offer 120 Hz.
A critical factor for 43 inches is pixel density: even at Full HD resolution the picture will be clear, but for Smart TVs and new generation consoles, 4K (3840×2160) is becoming the standard.
- 🌑 Contrast: Samsung (VA) wins in dark scenes.
- 👀 Viewing angles: LG (IPS) is better suited for viewing in a large group.
- 🎨 Color rendering: Both brands use quantum dots (QLED for Samsung, NanoCell for LG) in their higher-end series to expand the color gamut.
Wi-Fi module and wireless capabilities
The stability of Smart TV operation directly depends on the quality of the wireless module. Modern 43-inch Samsung and LG models are equipped with dual-band receivers that support the following standards: Wi-Fi 5 (ac) and in new models Wi-Fi 6 (ax)This allows you to stream heavy 4K content without buffering if the router is within line of sight.
However, there are nuances in the implementation of antennas. Engineers Samsung Antennas are often placed at the bottom of the case, which can create problems if the TV is on a low stand with metal elements. LG In some models, the antenna module is moved closer to the connection ports, which sometimes provides slightly better reception in difficult building conditions.
Both TVs support the technology Bluetooth for connecting wireless headphones and soundbars. This is an important feature for those who want to watch movies at night without disturbing their family. Screen Mirroring is also available: Samsung uses the protocol Smart View, and LG — Screen Share and AirPlay 2 support for Apple devices.
Recommended frequencies for Smart TV:2.4 GHz – for streaming photos and videos from your phone (best range).
5 GHz – for watching 4K videos online and cloud gaming (high speed).
It's worth noting that built-in Wi-Fi modules in TVs rarely have the power of industrial routers. If the signal in the receiving room is weak, both manufacturers recommend using a wired LAN connection or external Wi-Fi adapters (although support for the latter is limited to certified models).
Sound and multimedia functions
The thin frame of a 43-inch TV physically does not allow for the placement of powerful speakers, so both manufacturers use software algorithms to improve the sound. Samsung implements technology Q-Symphony (on compatible models) that allows you to sync your TV and Samsung soundbar speakers to create surround sound.
LG bets on virtual surround sound AI Sound ProThe system analyzes the content genre and optimizes the soundstage, enhancing voices in news reports or adding bass in action films. The basic models of both brands have a rather flat sound, and external speakers are recommended for a full movie experience.
An important multimedia aspect is codec support. Both "Korean" devices easily read popular video (MKV, MP4, AVI) and audio (AAC, MP3, FLAC) formats from USB drives. However, Dolby Vision is exclusive to LG (and other manufacturers), while Samsung uses its own standard HDR10+This means that content mastered for Dolby Vision will be displayed in standard HDR10 on Samsung TVs.
- 🔊 Power: Standard for 43 inches is 20W (2 x 10W).
- 🎵 Formats: LG supports Dolby Atmos (virtual), Samsung – Q-Symphony.
- 🎧 Bluetooth: Both brands support connecting two pairs of headphones simultaneously.
⚠️ Please note: Built-in TV speakers often fail to fully utilize the potential of modern soundtracks. If you plan to watch movies in high quality, budget for at least a simple soundbar.
Comparison table of characteristics
To systematize the information and make your choice easier, we will provide a direct comparison of the key parameters of typical representatives of the 43-inch mid-range lineup.
| Characteristic | Samsung (CU/AU Series) | LG (UR/UQ Series) |
|---|---|---|
| operating system | Tizen OS | webOS |
| Matrix type | VA (high contrast) | IPS (wide angles) |
| HDR support | HDR10+, HLG | Dolby Vision, HDR10, HLG |
| Remote control included | Smart Remote (batteries) | Magic Remote (cursor) |
| Game features | Game Mode, ALLM | Game Optimizer, G-Sync |
As the table shows, the choice often comes down to preference between the display type and HDR standards. If you're a fan of movies with dark scenes, Samsung is the better choice. However, if you often watch your TV from different angles on the couch, LG, with its IPS display, will be more practical.
Why doesn't Samsung use Dolby Vision?
Samsung doesn't license Dolby Vision due to royalties. Instead, they promote their free HDR10+ standard, which dynamically adjusts brightness but is supported by fewer studios than Dolby Vision.
Gaming capabilities and input lag
For owners of PlayStation 5 or Xbox Series X gaming consoles, input lag settings (Input Lag) are coming to the fore. In the 43-inch segment, both manufacturers demonstrate excellent results. Basic models offer a latency of around 10-13 ms in gaming mode, which is quite comfortable even for fast-paced shooters.
Samsung offers a gaming hub that aggregates streaming services and allows you to play cloud games without a console. LG LG also emphasizes compatibility with NVIDIA G-Sync and AMD FreeSync, which prevents frame tearing when connected to a PC. This makes LG TVs more versatile for hybrid use (TV + monitor).
It's worth remembering that full 120Hz and HDMI 2.1 support in 43-inch sizes is rare and typically only found in high-end, expensive models. Most budget and mid-range models are limited to 60Hz, which is plenty for casual gamers.
- 🎮 ALLM: Both brands have an automatic game mode.
- ⚡ VRR: Variable refresh rate support is more common with LG in this size range.
- ☁️ Cloud Gaming: Samsung Gaming Hub vs. LG Cloud Gaming.
⚠️ Please note: Panel specifications may vary within a single model series depending on the production date and delivery region. Always check the specific model on the manufacturer's website before purchasing.
☑️ What to check in the store before buying
Energy consumption and design
Modern 43-inch LED TVs consume little power, typically around 70-90 watts depending on brightness. Samsung And LG Light sensors are being implemented that automatically adjust screen brightness, saving energy and extending the life of the display. In Smart TV mode, power consumption may be slightly higher due to the active processor and Wi-Fi module.
In terms of design, both brands strive for minimalism. Thin bezels (Bezel-less) have become the standard. Samsung often uses elegant, thin legs on the edges, which require a narrow cabinet. LG often uses two sturdy legs in the center, which allows more freedom in furniture design, but requires the cabinet to be wider than the distance between the legs.
Wall mounting is also standard: VESA 200x200 mm. This allows for the use of most universal brackets. However, due to the different rear panel designs (the raised port areas), the distance from the wall may vary. Samsung TVs often have ports facing downward or sideways, while LG TVs may face straight back, which is important to consider when mounting in a recess.
Final verdict: what to choose?
The answer to the question "which TV is better" depends on your priorities. If deep blacks are important to you, you often watch movies in the dark, and you prefer classic controls— Samsung It will be an excellent choice. Its VA panels in this size provide contrast benefits.
If a large group of people will be watching TV, sitting on the sides, or you plan to use it as a second monitor for a PC - LG Its IPS screen and pointer remote will be more convenient. Dolby Vision support is also a compelling argument for lovers of high-quality HDR content.
Both devices feature reliable Wi-Fi modules and fast Smart platforms. Choosing either of these brands in the 43-inch segment is virtually impossible, as competition forces them to maintain a high standard of quality even in their budget lines.
Remember: in 2026-2026, the key differentiator will not be the hardware, but the ecosystem and user-friendliness of the interface. Therefore, "touching" the remote control and menu in the store is more important than looking at dry specification numbers.
Frequently Asked Questions (FAQ)
Is it possible to install third-party apps (APK) on Samsung or LG?
Officially, no. Both systems (Tizen and webOS) are closed. Apps can only be installed from official content stores. Installing APKs (like on Android TV) would require reflashing the device, which is complicated and voids the warranty.
Which remote control is better: with buttons or Magic Remote?
LG's Magic Remote (with a cursor) is more convenient for menu navigation and web browsing, as it functions like a mouse. The Samsung remote with buttons is more familiar to those who prefer precise keystrokes, but it also features a touchpad for cursor control.
Do these TVs support voice control?
Yes, both brands support voice assistants. Samsung uses Bixby and also integrates with Alexa and Google Assistant. LG uses ThinQ AI, which is also compatible with Alexa (via external devices), Google Assistant, and Alexa.
Is 4K necessary for a 43-inch diagonal?
At a distance of 1.5-2 meters, the difference between Full HD and 4K is already noticeable, especially in text and fine details. Considering that all content (YouTube, Netflix) is migrating to 4K, buying a Full HD TV in 2026 is impractical if your budget allows for 4K.
What's the difference between QLED and regular LED from Samsung?
QLED is a technology that uses a layer of quantum dots to improve color reproduction and brightness. QLED models are more expensive at 43 inches, but offer richer colors and better brightness than standard LED models (Crystal UHD).
