Never the right adapter
Some laptops only have USB-C, others have HDMI or DP. The adapters kept in the room rarely match, or someone has walked off with them. Ten minutes before the meeting people are still hunting for cables while the client waits.
Meeting Rooms
Wireless Presentation Solution
Guests and staff bring laptops with different ports, and meetings stall because the right cable or adapter is missing. Here the TX module goes into a USB-C or HDMI dongle and the RX module into a receiver box at the room display. Plug in the dongle, press the button, and the laptop is on screen, with no drivers or software to install.

PAIN POINTS
Pain Points
Connected, but no picture or no sound
The cable is in, yet the laptop doesn't detect the display, drops to a low resolution, or shows a picture with no audio. Often the source never gets the display's real EDID, so people end up re-plugging and changing display settings.
Swapping cables between presenters
When several people present in turn, every handover means unplugging, re-plugging and waiting for the display to come up. People at the far end of the table pass their laptops along, and the pile of cables on the table is easy to snag.
Rewiring after fit-out is costly
The display is on the wall and the table sits in the middle of the room, so HDMI has to run through floor ducts or a table box. Changing that after fit-out is expensive, and leased offices often don't allow cutting channels, so cables end up lying across the floor.

Room Display
USB-C and HDMI dongles
The module itself has an HDMI interface. A USB-C dongle adds a DP Alt Mode to HDMI converter on the carrier board, and DP works the same way. With a few dongle types on hand, visitors no longer need their own adapters.
Full EDID pass-through
The RX reads the room display's real EDID and passes it back to the laptop, so the laptop outputs what the display actually supports. This avoids black screens, missing audio and forced resolution drops. Embedded HDMI audio travels with the picture.
One receiver, several dongles
Each room has one receiver box and several dongles. Whoever presents next plugs in a dongle and presses the button, with no cables to swap. Modules ship pre-paired and link automatically at power-up, so attendees have nothing to configure.
Optional touch return
If the room display has a touch panel, connect its USB to the RX. Touch data travels back over the link and the laptop sees a local USB touch device with no driver needed, so presenters can tap and page through slides on the big screen.
Encrypted casting, the next room cannot pick it up
Dongle and receiver create their own key at pairing, and picture and sound are encrypted all the way. Rooms next to each other on the same band only show their own paired dongles, and nobody next door gets the picture.
SELECTION
Selection & Design Notes
- Pick the SKU by display resolution: 4K60 (ATE9460/9461) or 4K30 (ATE9430T/R) for 4K screens. Both also run 1080p.
- The range tier only sets coverage, not picture quality. The three wireless tiers are roughly 30-100 m, 100-300 m and 300-1000 m; choose by the distance on site.
- The module only takes HDMI. A USB-C dongle needs a DP Alt Mode to HDMI converter on the TX carrier board.
- VBUS must stay within 3.7-5.1 V; anything above 5.1 V damages the module. If the USB-C power source can negotiate a higher voltage, regulate it down first.
- For touch return, bring out a USB port on the RX carrier board for the touch panel. On 4K60, TX and RX pinouts differ, so each needs its own board.
FAQ
FAQ
Q1A guest's laptop only has USB-C. Can it present?
Yes. The module has an HDMI interface, and adding a DP Alt Mode to HDMI converter on the dongle's carrier board lets it plug straight into USB-C. The laptop's USB-C port does need to support video output (DP Alt Mode).
Q2Does the laptop need any software?
No. Video goes over HDMI, or over USB-C / DP through the converter on the carrier board. Touch panels and other USB HID devices appear to the laptop as local USB devices with no driver. TX and RX ship pre-paired and link automatically at power-up.
Q3For a small room, does a short-range tier mean lower picture quality?
No. Resolution is set by the product model and range by the Wi-Fi module tier. They are independent, and every tier runs 4K60. The tiers are roughly 30-100 m, 100-300 m and 300-1000 m, line-of-sight figures to be confirmed with samples.
Q4Can you build the wireless presentation system as OEM / PCBA?
Yes. We design the boards to your form factor, interfaces and range, handle ODM development and PCBA production, and offer white-label OEM; or buy the modules and design the carrier yourself. Validate link, range and picture with the ATE946X-KIT before prototyping.
