Belkin’s Cable-Killer: A Pocket-Size Dongle That Beams 4K Without Wi-Fi

The Day the HDMI Cable Disappeared

It was a few minutes past 9 a.m. in a Manhattan co-working space when Belkin’s PR manager reached into her back pocket, pulled out a dongle no larger than a pack of gum, and—in front of a dozen skeptical reporters—mirrored a MacBook to the 65-inch Samsung on the wall. No router, no password, no buffering wheel. The only thing missing? The familiar snake of black HDMI cable that usually trips everyone on the way to the coffee machine.

That quiet demo was the first glimpse of the Belkin Wireless HDMI Dongle, a palm-sized transmitter-receiver pair the company officially unveiled today. The pitch is simple: plug, pair, play—no Wi-Fi required.

How It Works (Without Stealing Your Wi-Fi)

Inside the anodized-aluminum shell is a 60 GHz wireless chipset—think of it as a miniature radar dish that beams uncompressed 4K at 30 fps across a room. Because the signal rides the unlicensed 60 GHz band, it dodges the crowded 2.4 GHz and 5 GHz airspace your Netflix traffic fights over. Latency? Belkin claims sub-15 milliseconds, quick enough for PowerPoint ninja clicks and the occasional Mario Kart lunch break.

‘We wanted something that “just works” the way Bluetooth headphones replaced the headphone jack,’ said Belkin product chief Lillian Cho. ‘Except this is Bluetooth for your television.’

Setup That Takes Longer Than Pouring Coffee

• Plug the transmitter into any HDMI source—laptop, Switch, camera, even a cable box.
• Connect the receiver to the TV or projector.
• Power both dongles via the built-in USB-C ports; they sync automatically.
• Press play.

The dongles memorize each other, so the second time you use them, the handshake is instant.

Price, Ports, and the Missing Pieces

At $179, the kit undercuts most wireless HDMI rigs that hover around $300, but it isn’t perfect. The 60 GHz frequency can’t penetrate walls, so line-of-sight matters. Range tops out at 30 feet. And while HDR and HDCP 2.2 are supported, 4K gamers itching for 120 Hz will have to wait for a future rev.

Still, for dorm rooms, pop-up conference suites, and backyard movie nights, the trade-off feels fair.

Why It Matters

Major laptop makers have already axed full-size HDMI ports; USB-C dongles clutter every backpack. Belkin’s solution skips the dongle soup entirely and turns any screen into a wireless mirror in seconds. If adoption spreads, conference-table grommets and classroom ceiling mounts could become the next tech relics.

Pre-orders open today on Belkin.com and Amazon, with shipments slated for August 14.
