Worried About Wireless 4K/HDR Video on LG’s Wallpaper OLED TV? Don’t Be

In an effort to simplify the connections on modern TVs, companies like LG and Samsung are currently offering an option on select TV models to move all of the source connections from the TV itself to a separate box located somewhere near the TV (generally, up to about 30 feet away). With this wireless connectivity, the only connection required for the TV itself is a power cord. This makes installation much simpler, whether you’re mounting your TV on a wall or on a stand out in the middle of an open floor plan living room.

Early implementations of this technology required line of sight connection between the box and the TV, which isn’t always convenient or practical. The high bandwidth required to transmit a full 4K video signal with HDR and with lossless immersive multi-channel audio can make the signal susceptible to dropouts in the form out audio and video glitches.

Samsung offers a wireless connection box called the “Wireless One Connect Box” on its Frame Pro TV and select Micro RGB TV models as well as an optional add-on for its S95H OLED TV. LG offers a wireless connection box called the “Zero Connect Box” in its W6 Wallpaper OLED TV as well as its MRGB9M Mini RGB LED/LCD TV.

But while Samsung’s commitment for wireless video performance is “Trust Me, Bro. It’s Fine,” (and it may very well be), LG has actually attained third party certification for its wireless audio and video connectivity.

This week, LG announced that its wireless Zero Connect Box has attained “True Wireless Lossless Vision” certification from TÜV Rheinland. This certification verifies that the specified models deliver “visually lossless 4K picture quality” at frame rates up to 165 Hz. Certified models include LG’s W6 OLED Wallpaper TV and MRGB9M Mini RGB LED/LCD TV.

According to LG, the certification verifies that LG wireless TVs preserve color accuracy, image detail and HDR tone reproduction during wireless video transmission. For this verification, TÜV Rheinland established a dedicated test standard covering key factors in the delivery of high-quality visual performance, such as input lag, color accuracy and gamma tracking.

Following the required evaluations, TÜV Rheinland confirmed that LG’s wireless TVs maintain accurate color reproduction, fine image detail and precise HDR tone performance within defined tolerance levels (relative to the input signal), qualifying them as “visually lossless” under international test standards. For consumers, this means cinematic films, live sports and next‑generation gaming can be enjoyed wirelessly with the same confidence in picture quality previously reserved for hard‑wired TV setups.

“True Wireless Lossless Vision certification confirms that our premium TVs can deliver award-winning picture quality and wireless freedom at the same time,” said Park Hyoung‑sei, president of the LG Media Entertainment Solution Company. “This achievement reflects LG’s long-standing commitment to enhancing the viewing experience and to elevating everyday living.”

As of April 2026, the LG W6 OLED TV is available to pre-order in the U.S. The MRGB9M is expected to be available later this year.

The Bottom Line

While wireless connection of source devices to a TV makes installation far less complex, some consumers may worry that doing so will impact the audio and video performance. With third party certification, buyers of LG’s wireless-enabled TVs can rest assured that that eliminating all these extra wires won’t mean sacrificing the picture and sound quality that they’re paying for.
