I have a Sony KV-27HS420 HDTV and an ATI Radeon 9700 AIW Pro, and I'm trying to configure X such that my display works with the DVI/HDMI interface. I used read-edid | parse-edid to obtain the modeline settings below. Mode 720x480 works well so long I don't switch to different inputs on the TV. If I do, the display sometimes becomes partially corrupted. Mode 1920x540 does not work and it appears that the TV wants to horizontally squash the image, even though it is solid black. I'm not sure why the EDID information says "1920x540" instead of "1920x1080". I haven't been able to find any 1080i modelines that work either. The display's native resolution is 1080i.
Does anyone have any experience they would like to share? $ read-edid | parse-edid Section "Monitor" # Block type: 2:0 3:fc Identifier "SONY TV" VendorName "SNY" ModelName "SONY TV" # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 15-46 VertRefresh 59-61 # Max dot clock (video bandwidth) 80 MHz # DPMS capabilities: Active off:no Suspend:no Standby:no Mode "1920x540" # vfreq 60.053Hz, hfreq 33.750kHz DotClock 74.250000 HTimings 1920 2008 2052 2200 VTimings 540 542 547 562 Flags "Interlace" "+HSync" "+VSync" EndMode Mode "720x480" # vfreq 59.940Hz, hfreq 31.469kHz DotClock 27.000000 HTimings 720 736 798 858 VTimings 480 489 495 525 Flags "-HSync" "-VSync" EndMode # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection
