From 2707cd016b12d5e64c4feefcb5740b65f0c46845 Mon Sep 17 00:00:00 2001 From: Petr Vandrovec Date: Tue, 8 May 2007 00:38:02 -0700 Subject: nvidiafb: Fix reversed DDC port After I added some debugging printks I've found that code became a bit confused because it believed that primary monitor is 1920x540, but later it found in CRTC0's registers that panel size is 1920x1200 (Windows also agree that 1920x1200 is primary monitor, and 1920x1080i secondary one). When I applied attached patch then my monitor became as happy as it was before I connected HDMI cable to secondary output.
