@BuZz said in Using composite video, can't see everything on the screen.:
Please try with disable_overscan=0 (or comment the line out) and enable overscan_scale=1 then adjust the overscan left/right/top/bottom
also note your gpu_mem=320 won't have any effect, as the gpu_mem_256, gpu_mem_512 and gpu_mem_1024 values override it.
Thanks for the tip, that did it! :)
