Careful Examination

Before purchasing used LED video wall, our professional team will Carefully inspect the condition of the LED display including: LEDs, ICs, power supplies, receiver cards (mainly using Novastar systems) and masks.

Brightness Measurement

We will test the LEDs using a professional brightness measurement tool to understand each wavelength of each LEDs RGB. Since it is an used LED display, so it is difficult to get the same batch of LEDs, we will buy some close LEDs.

Aging Test

All LED panels will be placed on an aging test frame and after 24 hours aging test, we will mark all dead pixels, damaged ICs, defective power supplies and disabled power cables.
