My EFI BIOS starts the graphics card up in my projector's preferred EDID mode, 1080@60i. The Intel driver does not clear the interlaced bit: #define PIPECONF_PROGRESSIVE (0 << 21) #define PIPECONF_INTERLACE_W_FIELD_INDICATION (6 << 21) #define PIPECONF_INTERLACE_FIELD_0_ONLY (7 << 21) This patch introduces a new PIPECONF_INTERLACE_MASK define and uses it to restore progressive mode.
