Hi all, I'm having problems getting the HDMI output of my motherboard working with a Samsung TV. The motherboard is an MSI 785GM-P45 with an AMD 785G chipset with an onboard Radeon HD 4200. I can see the desktop on the TV, but the edges are cut off and the colours are weird. Strangely, another computer connected to the same TV using VGA is working fine. I've looked over the Xorg.0.log file for the computer using HDMI and the one using VGA, and it looks like they get slightly different EDID information from the TV. I don't know enough about it though to know if it's related to my problem. Here's a couple of key lines from the logs where they seem to differ (I've attached the complete log files as well, there's another few places where they don't match but these seem the most notable to me): VGA: [ 10.808] (II) intel(0): EDID for output VGA1 [ 10.808] (II) intel(0): Manufacturer: SAM Model: 666 Serial#: 0 [ 10.808] (II) intel(0): Year: 2009 Week: 47 HDMI: [ 1026.636] (II) RADEON(0): EDID for output HDMI-0 [ 1026.636] (II) RADEON(0): Manufacturer: SAM Model: 667 Serial#: 1 [ 1026.636] (II) RADEON(0): Year: 2009 Week: 47 VGA: [ 10.809] (II) intel(0): Ranges: V min: 60 V max: 75 Hz, H min: 30 H max: 81 kHz, PixClock max 175 MHz HDMI: [ 1026.636] (II) RADEON(0): Ranges: V min: 24 V max: 75 Hz, H min: 26 H max: 81 kHz, PixClock max 235 MHz VGA: [ 10.809] (II) intel(0): EDID (in hex): [ 10.809] (II) intel(0): 00ffffffffffff004c2d660600000000 [ 10.809] (II) intel(0): 2f130103685832782aee91a3544c9926 [ 10.809] (II) intel(0): 0f5054bdef80714f8100814081809500 [ 10.809] (II) intel(0): 950fb300a940023a801871382d40582c [ 10.809] (II) intel(0): 450076f23100001e662150b051001b30 [ 10.809] (II) intel(0): 4070360076f23100001e000000fd003c [ 10.809] (II) intel(0): 4b1e5111000a202020202020000000fc [ 10.809] (II) intel(0): 0053414d53554e470a20202020200053 [ 10.809] (II) intel(0): EDID vendor "SAM", prod id 1638 [ 10.809] (II) intel(0): Using EDID range info for horizontal sync [ 10.809] (II) intel(0): Using EDID range info for vertical refresh HDMI: [ 1026.636] (II) RADEON(0): EDID (in hex): [ 1026.636] (II) RADEON(0): 00ffffffffffff004c2d670601000000 [ 1026.636] (II) RADEON(0): 2f130103801009780aee91a3544c9926 [ 1026.636] (II) RADEON(0): 0f5054bdef80714f8100814081809500 [ 1026.636] (II) RADEON(0): 950fb300a940023a801871382d40582c [ 1026.636] (II) RADEON(0): 4500a05a0000001e662150b051001b30 [ 1026.636] (II) RADEON(0): 40703600a05a0000001e000000fd0018 [ 1026.636] (II) RADEON(0): 4b1a5117000a202020202020000000fc [ 1026.636] (II) RADEON(0): 0053414d53554e470a20202020200129 [ 1026.636] (II) RADEON(0): 020322f1469004050320222309070783 [ 1026.636] (II) RADEON(0): 010000e2000fe305030167030c002000 [ 1026.636] (II) RADEON(0): b82d011d007251d01e206e285500a05a [ 1026.636] (II) RADEON(0): 0000001e011d8018711c1620582c2500 [ 1026.636] (II) RADEON(0): a05a0000009e8c0ad08a20e02d10103e [ 1026.636] (II) RADEON(0): 9600a05a000000180000000000000000 [ 1026.636] (II) RADEON(0): 00000000000000000000000000000000 [ 1026.636] (II) RADEON(0): 000000000000000000000000000000df Does anybody know where I should go from here? Is there anything else I can try? My thinking is somehow maybe the EDID information received over HDMI is incorrect, if so does that mean a quirk can be added for this TV so that it works properly? Thanks! -Shane O'Connell
