Question 1

How do I calculate LED screen resolution?

Accepted Answer

Divide the physical screen width and height in millimeters by the pixel pitch in millimeters. For example, a 5 m wide screen at P2.5 gives 5000 / 2.5 = 2,000 horizontal pixels.

Question 2

Why does my calculated resolution differ from vendor quotes?

Accepted Answer

Vendors quote resolution based on actual cabinet and module pixel matrices, which must align to whole cabinets. This calculator estimates from physical dimensions and pitch before a final cabinet layout is chosen.

Question 3

Should LED screens always match 1920 x 1080 or 3840 x 2160?

Accepted Answer

No. LED walls rarely match standard broadcast resolutions exactly. A video processor can scale standard content, but content should be designed for the actual pixel canvas when possible for the sharpest result.

Question 4

What resolution do I need for video content on an LED wall?

Accepted Answer

It depends on viewing distance and content detail. For close-range viewing with fine text, aim for at least FHD equivalent. For distant large-format content, lower resolution is acceptable. Always check with actual content at real viewing distance.

Question 5

How does pixel pitch affect screen resolution?

Accepted Answer

Smaller pitch produces higher resolution for the same screen size, but increases cost, power, and maintenance. Calculate resolution early in planning to ensure content quality meets expectations.

Question 6

Do I need to prepare content at the exact LED resolution?

Accepted Answer

Ideally yes. Content at the native pixel canvas looks sharpest. If that is not practical, a video processor can scale standard resolutions, but expect some softness or cropping depending on the aspect ratio match.
