Jestem bardzo zadowolony z pakowania i zamówienia. Zostało zrobione i gotowe na czas. Otrzymałem zamówienie zgodnie z oczekiwaniami. Znowu zrobi interesy z Penny i Anheerem. Odpowiedzieli na wszystkie moje pytania tak szybko, jak to możliwe. Ekran P3 wygląda absolutnie oszałamiająco. Zrobili dokładnie tak, jak zapytałem. Jestem bardzo szczęśliwy i pomogli mi go skonfigurować za pomocą TeamViewer. Jeszcze raz dziękuję Anheer

2 brightness and viewing angle
 
Indoor full color brightness 800cd/m2 brightness outdoor full color you want to 1500cd/m2 in order to ensure the normal operation of the display, otherwise it will not see the image displayed because the brightness is too low. The size of the brightness of the LED die is good or bad decision.
