Customer question: How can I confirm that my processor can drive the used screen I want to buy?
English explanation
Start with cabinet geometry. If a screen uses N cabinet columns and M rows, total cabinets equal N × M. Screen width and height come from the actual cabinet dimensions, while pixel resolution comes from the confirmed pixel count of one cabinet. For a 640 × 640 mm P2.5 cabinet, a planning estimate is about 256 × 256 pixels, but the manufacturer’s drawing and receiving-card data remain the final reference. Calculate each independent screen separately. A centre screen and two side screens may be controlled by one processor, but their windows, dimensions and pixel coordinates should not be treated as one simple rectangle. Add the pixel load of all zones for total capacity, then check each output port, maximum width/height, number of ports and any high-frame-rate or high-bit-depth limitations. Do not use a general “pixels per port” number from another controller. Confirm the exact processor or sending-card specification and operating mode. Also verify the source computer, content canvas and output resolution. A correct pixel calculation does not solve a wrong cascade, receiver configuration or poor signal link.
Service boundary
Pixel-load calculations are valid only after cabinet resolution and controller limits are confirmed. Final electrical and controller selection should follow the approved project drawing. —
