Five P2.5 indoor LED poster displays were installed at the Spanish Embassy in Portugal, creating a flexible digital display system for indoor presentations and visual communication.

Each LED poster screen measures:

640 × 1920 mm

With five units installed side by side, the complete display measures approximately:

3200 × 1920 mm

or:

3.2 × 1.92 meters

Each screen has a resolution of approximately 256 × 768 pixels, while the complete five-screen installation provides a combined resolution of approximately:

1280 × 768 pixels

The project demonstrates how multiple LED poster displays can be combined to create a larger digital presentation area while retaining the flexibility of individual screen units.

1. Project Overview

This indoor project uses five P2.5 LED poster displays installed at the Spanish Embassy in Portugal.

The screens are arranged side by side to create a larger coordinated display area.

Project Specifications

The installation can be used for presentations, cultural content, institutional information, videos and other digital visual communication.

2. Why P2.5 Was Selected

Pixel pitch is especially important for indoor LED displays because viewers are usually closer to the screen than they are to outdoor advertising displays.

A P2.5 LED display has approximately 2.5 mm between adjacent pixels.

This provides a practical balance between:

• Image detail
• Indoor viewing distance
• Pixel density
• Screen dimensions
• Project cost

For professional indoor spaces, P2.5 can provide clear image performance without requiring an unnecessarily fine pixel pitch.

It is suitable for applications where viewers need to see videos, images, text and presentation content from relatively close distances.

If you are comparing pixel pitch together with viewing distance, screen size and application, see our guide: How to Choose the Right LED Display for Your Business

3. Five LED Poster Screens Combined

One of the advantages of LED poster displays is their flexibility.

Each screen can operate as an individual digital poster.

However, multiple units can also be placed together when a larger display area is required.

For this project:

640 mm × 5 screens = 3200 mm total width

The complete installation therefore measures:

3200 × 1920 mm

or:

3.2 × 1.92 meters

This creates a wider presentation area suitable for landscape-format visual content.

The five-screen arrangement also allows the system to support different content strategies.

For example, the screens can display:

• One large synchronized image
• One panoramic video
• Separate content on different screens
• Institutional information
• Event announcements
• Cultural presentations

This gives the installation greater flexibility than a single conventional display.

4. Screen Size and Resolution

The resolution can be calculated from the physical screen dimensions and pixel pitch.

Single Screen

Screen size:

640 × 1920 mm

Pixel pitch:

2.5 mm

Horizontal resolution:

640 ÷ 2.5 = 256 pixels

Vertical resolution:

1920 ÷ 2.5 = 768 pixels

Therefore, each LED poster display has an approximate resolution of:

256 × 768 pixels

Five Screens Combined

With five screens installed side by side:

256 × 5 = 1280 horizontal pixels

The complete display resolution is approximately:

1280 × 768 pixels

The total display size is:

3.2 × 1.92 meters

and the total screen area is:

6.144 m²

This demonstrates an important LED display principle:

Pixel Pitch + Physical Screen Size = Final Resolution

Pixel pitch alone does not determine image resolution.

5. Why LED Poster Displays Work for Professional Indoor Spaces

LED poster displays can be suitable for formal and professional environments because they combine digital presentation capability with a narrow vertical form factor.

Possible applications include:

• Embassies
• Corporate offices
• Government facilities
• Hotels
• Museums
• Exhibition halls
• Conference rooms
• Reception areas
• Cultural institutions

Unlike conventional LCD video walls, LED poster screens are not limited to standard television dimensions.

Multiple units can be combined according to the available installation space.

This makes the system useful for projects where both visual impact and installation flexibility are important.

6. Visual Performance and Content

When several LED poster screens operate together, consistency becomes especially important.

The complete display should maintain similar:

• Brightness
• Color temperature
• Image detail
• Contrast
• Refresh performance
• Module consistency

If individual screens differ noticeably in brightness or color, the differences can become more visible when they are placed side by side.

For this reason, production testing and screen adjustment are important before shipment.

Suitable Content

The five-screen installation can display:

Institutional Videos
Official presentations, events and visual information.

Cultural Content
Landscape, architecture, art and cultural imagery.

Event Information
Schedules, announcements and meeting information.

Brand or Institutional Visuals
Logos, graphics and communication materials.

Wide-Format Video
One visual can extend across all five screens when the content is prepared for the complete display resolution.

Content Recommendation

Because the complete resolution is approximately 1280 × 768 pixels, content should ideally be prepared for the actual screen ratio rather than simply stretching standard vertical poster content.

7. Benefits of Modular LED Poster Screens

This flexibility is particularly valuable for B2B projects.

A customer may initially use several screens separately and later combine them for events, exhibitions or larger presentations, depending on the system configuration.

8. Installation Considerations

When multiple LED poster displays are positioned together, several details should be confirmed before installation.

Screen Alignment

The five screens should be positioned carefully so the complete installation looks visually consistent.

Content Configuration

The control system should be configured according to whether the customer wants:

• Independent content
• Synchronized content
• One large combined image

Viewing Distance

P2.5 is suitable for relatively close indoor viewing, but the final specification should still be selected according to the actual audience position.

Power and Signal

The quantity of screens affects power distribution and signal configuration.

Maintenance Access

Future module, power supply or control-system servicing should remain practical after installation.

These factors should be considered before production rather than after the screens arrive on site.

9. Project Specifications at a Glance

Single LED Poster Display

Product: P2.5 Indoor LED Poster Display
Quantity per unit: 1
Size: 640 × 1920 mm
Resolution: 256 × 768 px
Area: 1.2288 m²

Complete Five-Screen Installation

Quantity: 5 pcs

10. JunChen Display Project Approach

For multi-screen LED poster projects, JunChen Display evaluates the complete installation rather than considering each screen independently.

The project planning process includes:

Application → Screen Quantity → Screen Size → Pixel Pitch → Combined Resolution → Content → Viewing Distance → Installation

For this project, five 640 × 1920 mm P2.5 LED poster screens create a complete 3.2 × 1.92 m display system.

The objective is to balance:

Image Quality + Screen Flexibility + Installation Practicality + Content Performance

This project also demonstrates that LED poster displays are not limited to retail advertising.

They can also be used for professional, institutional and cultural environments where flexible digital communication is required.

12.Conclusion

This project at the Spanish Embassy in Portugal demonstrates the flexibility of multi-screen LED poster installations.

The project uses:

5 × P2.5 LED Poster Displays

Each screen measures:

640 × 1920 mm

Together, they create a display measuring:

3.2 × 1.92 meters

with an approximate combined resolution of:

1280 × 768 pixels

and a total LED area of:

6.144 m²

The modular design allows the screens to function individually or together, making this type of solution suitable for embassies, corporate offices, government facilities, exhibitions, hotels, museums and other professional indoor environments.

For B2B buyers, the key is not simply selecting a poster screen.

The complete system should consider:

Pixel Pitch + Quantity + Screen Arrangement + Combined Resolution + Content + Viewing Distance
