P1.8 or P2.5 for an indoor retail LED wall?

We are planning an indoor LED display wall for a retail store and choosing between P1.8 and P2.5:

Viewing distance: about 2.5–4 m
Screen size: about 2.5 m × 1.5 m
Use: branding and video content
Environment: indoor, no direct sunlight

Questions:

  1. At this distance, is the visual difference between P1.8 and P2.5 noticeable?
  2. Which one is better in terms of cost and maintenance?
  3. Are there big differences in control system requirements and power consumption?

Both can work at this distance, but they target different priorities.

  1. Image quality
    P1.8 is sharper, but P2.5 is already very clear at 2.5–4 m.

  2. Cost and maintenance
    P2.5 is more cost-effective and easier to maintain long term.

  3. System and power
    P1.8 requires higher system performance and slightly higher power consumption.

Choose P1.8 for premium visual quality.
Choose P2.5 for better value and stability.
