Two suppliers can quote the same 6 x 3 m P4 screen at prices far apart without either being dishonest. The difference usually sits in five places, and knowing them lets you compare quotes on equal terms instead of on the headline number.
| Driver | Cheap version | Better version |
|---|---|---|
| Pixel pitch | Coarser pitch, fewer LEDs | Finer pitch, more LEDs and more driver ICs |
| LED and driver brand | Unbranded lamps and drivers | Named lamps (e.g. Nationstar, Kinglight) with datasheets |
| Power supply | Generic supply, shorter life | Meanwell or equivalent, higher efficiency and MTBF |
| Cabinet | Steel or thin plastic, heavier | Die-cast aluminium, tighter tolerance, better cooling |
| Control system | Basic sending card, no redundancy | Nova / Colorlight with backup and calibration |
| Freight and packing | Quoted loosely or excluded | Stated clearly with trade term and packing |
| Warranty and spares | Verbal, no pool | Written warranty and a stocked spares kit |
A quotation is only comparable when the scope matches. Check that both quotes state: the trade term (FOB, CIF or DDP), what packing is included, whether the control system and sending card are in the price, whether spare modules are included, what the warranty covers and for how long, and whether installation or commissioning support is part of the deal. A lower FOB price with freight and control excluded is often the more expensive option.
For budgeting, treat the display as roughly 60–70% of the project cost. Steel structure, installation, power supply work, rigging and freight make up the rest, and they vary far more between sites than the screen itself does. Ask for a quotation that separates the screen, the packing and the freight so you can see each part.
Send us your screen size, viewing distance and destination country. You will get a quotation that states the cabinet count, the trade term, the packing and the warranty in writing — so it can be compared line by line.
