[gentoo-user] xorg.conf (HDMI vs DVI-D)
Hello, We'll I've got a new samsung monitor 2333HD-1 that is verified 1920x1080. Finally, I got it working on a dvi-d-2-dvi-d video cable with no problems...(minimal xorg.conf) and ati-drivers. OK, so I switch to a DVI-Don video card to HDMI on the monitor and it comes in, but the bottom and sides are missing. OK so I found this thread that I'm guessing is on the mark: http://www.phoronix.com/forums/showthread.php?t=23826 But, I'm a little bit 'chicken' with xorg.conf, not to mention messing with the dot clock et al... CLUCK CLUCK CLUCK Anyone want to venture a guess about the display settings, suggested in the link? that I should use? A better way? Here's the (example) math I use to use: # DisplaySize 426 266 # width = (1680pix / 100pix/in) x [25.4mm/in] = 427 -- 426 # hieght = (1050pix / 100pix/in) x [25.4mm/in] = 267 -- 266 Here is what's working with the dvi-dvi cable: Section Monitor Identifier aticonfig-Monitor[0]-0 Option VendorName ATI Proprietary Driver Option ModelName Generic Autodetecting Monitor Option DPMS true HorizSync30-81 VertRefresh 56-75 EndSection Section Device Identifier aticonfig-Device[0]-0 Driver fglrx BusID PCI:2:0:0 # Option XAANoOffscreenPixmaps true EndSection Section Screen Identifier aticonfig-Screen[0]-0 Device aticonfig-Device[0]-0 Monitoraticonfig-Monitor[0]-0 DefaultDepth 24 SubSection Display Viewport 0 0 Depth 24 Modes1920x1080 1680x1050 1280x1024 1024x768 EndSubSection EndSection

I guess this is the question to me: Is the monitor doing overscan on HDMI? or Is the ATI driver doing underscan on HDMI based on the assumption that the monitor will overscan? Check if your monitor on-screen menu has overscan settings (or change it to PC Mode or something, the manufacturers all have different terminology). Otherwise if it has no settings you'll have to conitunue messing with the ATI drivers instead.

You have nothing to fear from fiddling with clock settings on a flat panel. That only ever applied to CRT displays where running the horizontal frequency higher than the circuit was designed for would increase the HT voltage at the final anode - which often cracked the thin glass on the tube neck. Flat panels do not have a concept of scan coil to drive, there is no HT transformer and there is no tube to have 28kV inside of. The owrst you can do is to get no picture. -- alan dot mckinnon at gmail dot com
