This is what I am getting with the above command. I think it is giving information about only one monitor. If I am correct that information belongs to the laptop's monitor. What about the external monitor's specs? $sudo get-edid | parse-edid parse-edid: parse-edid version 1.4.1 get-edid: get-edid version 1.4.1 Performing real mode VBE call Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0 Function supported Call successful VBE version 300 VBE string at 0xc0248 "ATI ATOMBIOS" VBE/DDC service about to be called Report DDC capabilities Performing real mode VBE call Interrupt 0x10 ax=0x4f15 bx=0x0 cx=0x0 Function supported Call successful Monitor and video card combination does not support DDC1 transfers Monitor and video card combination supports DDC2 transfers 0 seconds per 128 byte EDID block transfer Screen is not blanked during DDC transfer Reading next EDID block VBE/DDC service about to be called Read EDID Performing real mode VBE call Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0 Function supported Call successful parse-edid: EDID checksum passed. # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:f # Block type: 2:0 3:fe # Block type: 2:0 3:fe Identifier "SEC:5032" VendorName "SEC" ModelName "SEC:5032" # Block type: 2:0 3:f # Block type: 2:0 3:fe # Block type: 2:0 3:fe # DPMS capabilities: Active off:no Suspend:no Standby:no Mode "1680x1050" # vfreq 59.999Hz, hfreq 64.799kHz DotClock 119.230000 HTimings 1680 1728 1760 1840 VTimings 1050 1052 1058 1080 Flags "-HSync" "-VSync" EndMode # Block type: 2:0 3:f # Block type: 2:0 3:fe # Block type: 2:0 3:fe EndSection -- Kamaraju S Kusumanchi http://www.people.cornell.edu/pages/kk288/ http://malayamaarutham.blogspot.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
