From 1a3b09dc9aeaaab25ff736c2443df423a8fb655e Mon Sep 17 00:00:00 2001 From: Jon Dufresne Date: Wed, 15 Oct 2008 22:03:49 -0700 Subject: [PATCH] fbmon: fix EDID parser to detect interlace modes The current EDID parser in the linux kernel ignores interlace modes. The patch looks for the edid interlace flag and adjusts the vertical resolution if it is found.
