Video Out/VGA Display Skipping Every Other X Pixel

Honored Contributor II

Hey, so I'm using a De1-SoC and programming in Assembly using the the Nios II instruction set found here: 

So I was just experimenting with the video out pixel buffer (at memory located 0x8000000) and tried to create a screen that was just entirely white. I looped through each pixel and coloured each one white but I am getting vertical lines that are not being coloured in. I have provided pictures as well as screenshots of the documentation I used to create the image, my source code, and the output on my VGA monitor. Vertical columns not being printed white Video Out Documentation - 1 Video Out Documentation - 2 Video Out Documentation - 3 


Any help is greatly appreciated! Cheers
