What specifications are required for ordering an LED display?

What needs to be clarified before ordering an LED display?

Please specify the pixel pitch (P1.25, P1.53, P2.5). This determines the display resolution.

Please provide the exact length and width of the screen area.

Is it for indoor or outdoor use? This affects brightness and waterproof ratings (IP rating).

Do you have a preferred cabinet size (e.g., 500x500mm or 1000x500mm)?

Please confirm the receiving card brand and whether you need video processors or brackets included.
