1. Introduction: Why Screen Size and System Fit Matter

When equipping a mid-sized meeting room (typically 20–40㎡), an oversized display wastes space while an undersized screen underdelivers on visual clarity. The right LED All-in-One display not only looks professional but also boosts productivity during team discussions, client presentations, or hybrid meetings.

This article guides B2B buyers on selecting the most practical configuration in 2025.

2. Ideal LED Display Sizes for Mid-Sized Meeting Rooms

In 2025, the most popular LED All-in-One screen sizes for medium rooms are:

Screen Size Ideal Use Case

138 inches Boardroom with 8–12 participants

165 inches Client-facing or hybrid room use

110 inches Compact mid-sized rooms (budget)

Larger screens provide better viewing angles and visibility from the back seats. If your space is less than 5 meters deep, 138” is typically optimal.

3. Pixel Pitch & Resolution: Balancing Detail and Budget

For sharp PowerPoint slides, Excel sheets, and hybrid calls:

·  Recommended pixel pitch: P1.2 or P1.5

·  Resolution for 138” P1.2: ~1920x1080 or higher

·  Note: Lower pitch = higher price. Always match pitch with viewing distance.

Viewing Distance Pixel Pitch Visual Effect

2–3 meters P1.2 Sharp

3–4 meters P1.5 Standard

4. Dual-System Setup: Android + Windows in One Display

Most mid-to-high-end LED All-in-One displays now feature dual OS systems:

·  Android for wireless casting, app use, whiteboarding

·  Windows (OPS slot-in) for Teams, Zoom, Microsoft Office

Ensure:

·  The OPS is removable and upgradeable

·  Screen supports input switching with one click

·  Compatibility with remote IT management software

5. Collaboration Features: Touch, Whiteboard, and Casting

Interactive mid-sized rooms benefit from:

·  20-point IR or capacitive touch

·  Smart annotation tools for any input

·  QR code export for meeting notes

·  Support for AirPlay, Miracast, Chromecast

Touch isn’t essential for all clients but enhances brainstorming and agile workflows.

6. Installation Modes: Wall-Mount, Mobile Stand, and Embedded

Mid-sized spaces need flexible mounting based on wall load and room use:

Mode Pros Common Scenario

Wall-mounted Clean look, saves space Permanent conference room setup

Mobile stand Reusable, flexible Shared resource across rooms

Embedded wall Premium finish, concealed setup VIP or executive boardrooms

Check: Does the vendor offer mobile stand packages or support drywall mounting?

7. Maintenance & Support: What B2B Buyers Should Ask Vendors

Even for smaller deployments, after-sales support determines long-term success.

Ask about:

·  Hot-swappable front modules

·  Panel availability in your country

·  Remote diagnostic tools or service access

·  Spare parts policy for 3–5 years

8. FAQs: Sizing, OS, and Application Compatibility

Q1: Is 138” too large for a 25㎡ meeting room?

A: No. As long as you have 3.5m+ viewing distance, 138” is ideal.

Q2: Can we install our own video conferencing software?

A: Yes, if your model includes a Windows OPS or supports app sideloading on Android.

Q3: Does the display work with MacBooks?

A: Yes. Ensure it supports AirPlay or use HDMI input for full compatibility.
