Small meeting rooms are built for quick discussion and decision-making, but screen sharing often becomes the part that slows everything down. When several people need to present in sequence, simple actions start to add up. HDMI cables are passed from one person to another. Adapters are swapped and sometimes do not fit. The display goes black for a few seconds while the signal reconnects. Each switch breaks the rhythm of the meeting.
This article looks at how small meeting rooms can handle turn-by-turn screen sharing more smoothly by using a wireless HDMI setup, with the G50R20 series as a practical example based on real meeting workflows.
1. Where Presenter Switching Usually Breaks Down
In a typical small meeting room, presenters rarely use the same device. One person may bring a laptop, another a mini PC, and someone else a media player. With a wired setup, each presenter must repeat the same steps.
The cable is unplugged from the previous device. A new adapter is connected. The cable is plugged back in. The display waits to detect the signal. Sometimes the wrong input is selected, and someone has to walk to the screen to change it. Even when everything works, this process takes time and pulls attention away from the discussion.
Power issues are another common problem. Some HDMI ports cannot supply enough power for active adapters. When the signal fails, the meeting pauses while people try different cables or USB ports.
Movement is also restricted. Presenters tend to stay close to the screen or table because of cable length. This makes it harder to point at content, interact with others, or move naturally during a presentation.
After repeating these steps in numerous meetings, many teams begin to seek a method for switching presenters without having to touch cables or disrupt the flow.
2. A Practical Wireless Approach for Small Meeting Rooms
A wireless HDMI system changes the process at a basic level. Instead of sharing one cable, each presenter uses their transmitter. The display stays connected to a single receiver at all times.
With the G50R20 setup, the receiver connects to the TV, projector, or conference panel once and remains in place. Each presenter plugs a transmitter into their device before the meeting starts. There is no need to approach the display or swap cables during the session.
Because the system uses a direct wireless HDMI link, it does not depend on the office network, WiFi login, or casting apps. Once powered, the transmitter and receiver recognize each other automatically. This keeps the workflow consistent from meeting to meeting.
3. How Multi-Device Wireless Screen Sharing Works in Practice
3.1 Getting the Room Ready
The receiver is connected to the display using HDMI and powered with a USB-C cable or a standard 5V adapter. After it powers on, it stays active as the display endpoint for the room.
Each presenter connects a transmitter to their laptop or other HDMI-output device. Power is supplied through USB-C, either from the device itself or an external power source. At this point, all presenters are ready before the meeting even begins.
3.2 Switching During the Meeting
Only one transmitter sends video to the receiver at a time. When the next presenter needs to share their screen, the system switches the active transmitter. The display remains stable, and the transition happens without unplugging anything.
This approach works especially well in small meeting rooms where people present one after another rather than at the same time. The G50R20 supports up to eight transmitters paired with one receiver, which covers most small team scenarios.

4. Comparing the G50R20 1080P and 4K Versions
The G50R20 series is available in two main versions, each suited to different meeting needs.
| Feature | G50R20 1080P @ 60Hz | G50R20 4K @ 30Hz |
| Output Resolution | 1920 × 1080 (Full HD) | 3840 × 2160 (4K UHD) |
| Refresh Rate | 60Hz | 30Hz |
| Visual Behavior | Smooth motion and transitions | Sharper detail for static content |
| Typical Content | Slides, live demos, software interfaces | Detailed charts, images, design layouts |
| Perceived Latency | Lower and more responsive | Slightly higher due to data rate |
| Wireless Mode | Point-to-point wireless HDMI | Point-to-point wireless HDMI |
| Transmitter Support | Up to 8 transmitters to 1 receiver | Up to 8 transmitters to 1 receiver |
| Wireless Band | Dual-band 2.4GHz and 5GHz | Dual-band 2.4GHz and 5GHz |
| Best Room Type | Small to medium meeting rooms | Small rooms with stable wireless conditions |
The G50R20 1080P version works better when presenters switch often, slides include animations, or software demonstrations involve frequent screen updates. The higher refresh rate makes transitions feel smoother.
The G50R20 4K version fits meetings where visual detail matters more than motion, such as reviewing large charts, detailed images, or design files.
5. Practical Usage Notes
Wireless HDMI performs best indoors with limited interference. Thick concrete walls or heavy wireless traffic can affect signal stability. In most small meeting rooms, placing the receiver near the display and avoiding obstructions provides consistent results.
Transmitters need stable power. If a device’s HDMI port does not supply enough power, using USB power prevents unexpected disconnects.
Latency typically stays within 50 to 80 milliseconds. This is not noticeable for presentations, documents, or video playback, but it should be kept in mind for tasks that require precise timing.
6. Adapting to Common Meeting Scenarios
In daily team meetings, wireless HDMI allows rapid hand-offs between speakers without setup delays.
In client presentations, a clean, cable-free setup creates a more professional impression and helps meetings start on time.
In training sessions, instructors can switch between devices or participants without interrupting the session flow.
In hybrid meetings, in-room participants can share content easily while remote attendees follow along through conferencing software.
7. Selecting the Right Wireless HDMI Setup
When choosing a wireless HDMI solution for a small meeting room, real usage matters more than headline specifications. Simple setup, quick switching, broad device support, and stable performance are what keep meetings productive.
We built the G50R20 wireless HDMI transmitter and receiver system around these needs. By reducing cable handling and simplifying presenter switching, it removes the most common friction points in screen sharing for small meeting rooms.
