From: Clint Taylor <clinton.a.taylor@xxxxxxxxx> 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.
