LG's separate transmitter box finally delivers cable-free 4K gaming and movies up to 30 feet from your devices
LG's Zero Connect Box transmits 4K video wirelessly to compatible OLED TVs, eliminating cable runs between your devices and screen. All inputs (consoles, Blu-ray, streaming boxes) connect to the separate box, which beams content up to 30 feet away. Only a power cord reaches the TV, perfect for clean wall mounting. Supports 4K@144Hz, NVIDIA G-Sync, and AMD FreeSync with minimal latency.
Wireless home theater has been a broken promise for over a decade. Manufacturers have dangled the dream of cable-free entertainment only to deliver laggy, compressed video that serious viewers rejected immediately. LG's Zero Connect technology finally changes that equation with a dedicated transmitter box that handles the heavy lifting while your TV hangs on the wall connected by nothing but a power cord.
The concept is elegantly simple: instead of routing HDMI cables from your entertainment center to a wall-mounted TV, every device plugs into LG's separate Zero Connect Box. That box transmits visually lossless 4K video and full audio wirelessly to the display. The result? A TV that can sit up to 30 feet from your gear with zero visible cable runs.
Gaming consoles, Blu-ray players, streaming devices, and soundbars all plug into the Zero Connect Box via HDMI 2.1, USB, optical, or Ethernet.
The box converts and beams high-bandwidth 4K signals using a dedicated frequency designed for low-latency, visually lossless transmission.
The OLED panel receives the signal and renders your content. Only a single power cable connects to the TV, nothing else.
The biggest concern with any wireless video solution is latency. Gamers need sub-frame response times, and previous wireless HDMI solutions introduced enough lag to make competitive play impossible. LG engineered Zero Connect specifically to address this problem.
The system supports full 4K resolution at up to 144Hz refresh rates, higher than most gaming monitors. Both NVIDIA G-Sync and AMD FreeSync variable refresh rate technologies work natively, eliminating screen tearing without the performance penalties of traditional V-Sync.
Independent tests show Zero Connect adds approximately 1-2ms of latency, imperceptible to all but professional esports players and well within acceptable ranges for console and PC gaming.
For decades, better TV sound meant choosing between two imperfect options. Traditional AV receivers deliver genuine surround sound but require running speaker wire throughout your room and configuring complex settings. Soundbars promise simplicity but rarely deliver convincing spatial audio, especially for height effects.
Dolby's new FlexConnect platform introduces a third path: place compatible speakers anywhere in your room and let the system figure out the rest. The TV's microphones detect each speaker's position and capabilities, then automatically calibrates the audio to maximize Dolby Atmos performance.
TV microphones detect speaker positions and calibrate audio automatically. Setup takes under two minutes.
Place speakers wherever works for your room. The system adapts to your layout instead of demanding precise positioning.
Unlike soundbars that override built-in speakers, FlexConnect incorporates them for center channel dialog and effects.
Compatible speakers include up-firing drivers for overhead Atmos effects without ceiling-mounted hardware.
TCL launched first with their Z100 FlexConnect speakers: 170-watt units featuring front-facing woofer, midrange, and tweeter plus an up-firing driver for height effects. Priced at $400 each, you can configure up to four speakers plus an optional $500 subwoofer.
Note: Current FlexConnect speakers only work within their brand's ecosystem. Cross-brand compatibility isn't required by Dolby's specification, though it's not prohibited either.
The technology impresses, but practical limitations exist
Zero Connect's 30-foot range sounds generous on paper, but real-world performance depends heavily on what sits between the box and TV. Thick walls, metal cabinets, and certain building materials can interfere with the signal. LG recommends line-of-sight placement when possible, though the system can work through standard drywall without issues.
The Zero Connect Box itself needs ventilation and power, so you're trading cable management at the TV for a device that still requires placement somewhere in your room. For most users, this means positioning the box inside an entertainment center or media cabinet. This works fine as long as the cabinet isn't fully enclosed metal.
Full connectivity breakdown for LG's wireless transmitter
LG's Zero Connect delivers on the cable-free promise that previous wireless video solutions couldn't keep. For those willing to invest in compatible OLED hardware, it fundamentally changes what's possible with TV placement and clean installation.
Combined with emerging technologies like Dolby Atmos FlexConnect, we're entering an era where premium entertainment systems no longer require running cables through walls or precise speaker placement. The technology exists. It just requires buying into specific ecosystems.
For professional installations, Zero Connect TVs simplify mounting dramatically. Instead of routing HDMI through walls (which can introduce signal degradation over long runs), installers only need to handle power. The result is faster installation, cleaner aesthetics, and fewer potential failure points.
If visible cables ruin your aesthetic, Zero Connect is the only solution that truly eliminates them.
4K@144Hz with VRR support means no compromise on performance despite the wireless connection.
When running cables would require major construction, Zero Connect provides a practical alternative.
Offices, lobbies, and retail spaces benefit from simplified installation and premium presentation.
