[Intel-gfx] [PATCH] drm/edid: Reduce horizontal timings for pixel replicated modes
clinton.a.taylor at intel.com
clinton.a.taylor at intel.com
Mon Aug 18 23:02:34 CEST 2014
From: Clint Taylor <clinton.a.taylor at intel.com>
Pixel replicated modes should be 720 horizontal pixel and pixel
replicated by the HW across the HDMI cable at 2X pixel clock. Current
horizontal resolution of 1440 does not allow pixel duplication to
occur and scaling artifacts occur on the TV. HDMI certification
7-26 currently fails for all pixel replicated modes. This change fizes
the HDMI certification issues with 480i/576i.
V2: Removed interlace flag from VICs 44 and 45. Will be submitted in
another patch. Various other formatting fixes.
