Still didn't manage to fix this ... I installed the tool read-edid, then (under time pressure) had to gave up and settled at 1680x1050 io 1920x1200, although this generates some flicker. Now I have a Samsung 26" TV-set; the best resolution acc. to the manufacturer is 1360x768. I have exactly the same problem: the picture is displaced to the right by a small offset of maybe 100 pix, and there is black vertical bar; at the right side a small strip is missing. My Monitor-section (as generated with read-edid) looks like this, which seems to be appropriate acc. to googling: > Section "Monitor" > # Block type: 2:0 3:fd > # Block type: 2:0 3:fc > Identifier "SAMSUNG" > VendorName "SAM" > ModelName "SAMSUNG" > # Block type: 2:0 3:fd > HorizSync 30-61 > VertRefresh 60-75 > # Max dot clock (video bandwidth) 90 MHz > # Block type: 2:0 3:fc > # DPMS capabilities: Active off:yes Suspend:no Standby:no > > Mode "1360x768" # vfreq 60.015Hz, hfreq 47.712kHz > DotClock 85.500000 > HTimings 1360 1424 1536 1792 > VTimings 768 771 777 795 > Flags "+HSync" "+VSync" > EndMode > > # Block type: 2:0 3:fd > # Block type: 2:0 3:fc > EndSection How can I center the picture? Perhaps I can tweak one of the parameters? Or could there be a problem with the Openchrome driver or CN700 chip set?
