    LED Wall Mapping - 1:1 Pixel Accuracy

    by niccab » Tue Jul 09, 2019 10:56 pm

    Hi madMapper folks!

    I am attempting to use madMapper to output multiple videos with a 192 x 192 resolution on an LED wall with a resolution of 1920 x 1080.

    I have not yet achieved 1:1 pixel accuracy.
    Are there any fields to enter your desired mapped resolution? Because I haven't found that, I have been manually moving the image output pixel by pixel, physically marking 192 x 192 pixels on the LED wall itself.

    I created a 192x192 px test image file with a 1px border, and mapped it to fit within the marked out 192 x 192 pixels on the LED wall. MadMapper displays this test image with an interpolated border, where the 1px width bleeds into the row of LEDs next to it at a lower brightness to create a softer edge.

    Anyone have tips on how to reliably make madMapper output a true 192 x 192 resolution without interpolation?

    This is part of our tests. You should not activate the "antialiasing filter" on the fixture. Look at this demo: https://www.dropbox.com/s/gwjdblxrp9i42 ... s.mov?dl=0
