[QUOTE="TerryK, post: 115854, member: 32169"] Thanks but keep in mind that it's only how many pixels one can drive from a port without pulling too much current through it. The pixels at the end of the string probably will not look as you want due to voltage drop. There is a paradox in researching string currents and number of pixels from the effect of pixels drawing less current further down the string because they see a reduced voltage (from voltage drop earlier in the string). That reduced pixel current helps to lessen voltage drop in the earlier portion of the string. Most individuals I think power the beginning of a string from the controller and then power inject along the string length to minimize voltage drop giving them the ability to drive the pixels to the levels they want in their display. Pretty much how I do it other than the beginning of the string is power injected from the supply rather than through the controller. The decision to not power inject and power only from the controller, data only from the controller and power inject the string, or the combination of power from the controller and power injection is a decision you will need to make based on how you think one of those best 'fits' your display.

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
