Castmate 4K
This is a wireless video transmission kit (TX transmitter + RX receiver). The concept is to “wirelessly replace” a physical HDMI cable. It is not a TV stick, does not require internet, and cannot stream on-demand content. It transmits directly via hardware. Simply put: if there is an HDMI port, it can send the display signal over—like an invisible cable.
Completely no Wi-Fi needed! It creates its own dedicated 5GHz transmission channel. Whether you’re camping in the mountains, at a crowded trade show with congested networks, or in a basement meeting room, just plug it in and it works.
No setup required. Plug the RX into the display and the TX into the computer, press a button, and it auto-projects within 3 seconds. Even elderly users can operate it easily.
Equivalent to a physical cable. It supports 4K@60Hz lossless output, optimized especially for business presentations. Small Excel numbers and CAD drawing lines remain sharp and clear even on an 80-inch screen.
Practically real-time. With ultra-low latency technology, mouse movement and video playback are very smooth, delivering a large-screen experience without noticeable delay.
Up to 30 meters in open space. In typical office environments with partitions, around 10–15 meters. This means you can sit at the back of a large meeting room and still control the front display easily.
Actual distance depends on physical obstacles; passing through walls or glass partitions may reduce range or cause interruptions.
MacBook: All series (M1–M4), USB-C supported directly.
iPhone: iPhone 15 / 16 and above (USB-C) plug and play; iPhone 14 and earlier require an official adapter.
Android / Windows: Works as long as the USB-C port supports video output (DP Alt Mode).
No problem! Including Nintendo Switch, Steam Deck, and ROG Ally—any device with USB-C video output can escape the small screen and enjoy a big-screen experience anywhere.
Yes! The product supports HDCP encrypted transmission and is compatible with major OTT platforms (depending on device support). Whether streaming shows or watching movies, it ensures stable output and turns your living room into a private 4K theater.
Physical-level encryption. Data is transmitted via a dedicated point-to-point encrypted channel, without going through public networks or connecting to the internet. Your confidential financial reports and client contracts cannot be intercepted.
Extremely easy switching. Just pass the TX transmitter to the next presenter, and it reconnects within seconds. No need to unplug cables, pass wires, or adjust resolution settings

No built-in battery and no charging required, but it must be continuously powered during use.
RX receiver: must be connected to a USB-C power cable to operate.
TX transmitter: usually powered directly by the connected device, but if the phone/laptop has low power or when using an HDMI adapter, external power can be connected for stable output.
In addition to USB-C devices, HDMI signal sources are also supported.
By using an HDMI-to-USB-C adapter, projection and video transmission can be done normally.
After official product launch, we will provide compatible HDMI-to-USB-C adapter accessories for users who need them.
