There are mainly two ways to upload programs for the LED signs: USB drive and Wi-Fi. Firstly, USB drive. It has many different names, U disk=USB flash drive=USB disk=USB thumb drive. USB drive is used as a tool to move programs from the computer to the LED display, which is very convenient to use. But it still needs a computer to generate the program, and the software used to design the program in the industry can only run on Microsoft’s Windows version, so you must have a computer. Note that the software does not support Apple’s MAC, nor does Google’s Chromebook.
When you run software HDPlayer, you need to select the correct device type and set resolution. Don’t select others, it will go wrong. The screen will say "Device Does Not Match"
After purchasing my LED sign, I can design a free program for you. I will show you the video that is displaying your program in 7 days. If you are not satisfied, I can modify it.
After the design is completed, send you some files, copy them to the USB drive (in the product box), and then insert it into the LED panel.
You can use computer, MAC, laptop, Chromebook and other devices that support USB DRIVE to copy files.
If need USB drive with programs, need 20 days shipping time, the USB drive and shipping cost are $10.
