** Description changed: I'm running current release of Lucid Lynx desktop version and trying to use 1080p with this TV. This report includes description of the released official (non-RC) 10.04 LTS desktop version. BIOS is now the latest 0028 version. Two tests: 1. Connect HDMI from motherboard to Onkyo amplifier and from Onkyo amplifier to TV: " Onkyo 7" " text shown in display settings. 2. Connect HDMI from motherboard directly to TV: " Samsung 7 " text shown in display settings. The first setup is the one I'm planning to use. What happens is that in both tests 1 and 2 couple of centimeters (1 inch) is missing at least from top and bottom of the screen (probably also from left and right). I can't see any menus but they are there if I scroll the mouse "outside" the visible area and click there. A workaround to this problem is to use "Screen Fit" option in the TV, not "16:9". The "Screen Fit" option has to be used with both 1920 x 1080 (16:9) and 1280 x 720 (16:9) resolutions. The resolutions seem to be correct however: if I take a screenshot then it is exactly 1280 x 720. In summary, there are three problems with this TV: 1) "Screen Fit" option has to be selected. 2) "Searching for Signals" problem in 1920 x 1080: it starts when scrolling in Firefox or moving windows. 3) Flickering problem in 1920 x 1080: the picture "tears", this may include problem 2. 4) No HDMI audio. There is only a faint "click" sound when trying to play audio. Scrolling in Firefox usually causes symptom 2 but the "Searching for Signals" text may disappear and the picture comes back if scrolling back. Flickering in problem 3 may disappear if moving the window back, but it starts again especially if window is on the border of the screen. Problems 2 and 3 do not occur with resolution 1280 x 720 so it is full HD specific. I also tried to install the latest PPA kernel (2.6.34-999). With this kernel problem 4 vanishes and the HDMI audio is played correctly. Also problem 3 is much less severe with the kernel update. Anyway even with the kernel update problems 1 and 2 remain. + + --- + Architecture: amd64 + DRM.card0.DisplayPort.1: + status: disconnected + enabled: disabled + dpms: On + modes: + edid-base64: + DRM.card0.DisplayPort.2: + status: disconnected + enabled: disabled + dpms: On + modes: + edid-base64: + DRM.card0.HDMI_Type_A.1: + status: connected + enabled: enabled + dpms: On + modes: 1280x720 1920x1080 1600x1200 1680x1050 1280x1024 1280x1024 1440x900 1440x900 1280x960 1280x800 1152x864 1280x720 1024x768 1024x768 1024x768 832x624 800x600 800x600 800x600 640x480 640x480 640x480 640x480 640x480 720x400 + edid-base64: AP///////wA9ywEAAAAAAf//AQOAEAl4Cu6Ro1RMmSYPUFS974BxT4EAgUCBgJUAlQ+zAKlAAR0AclHQHiBuKFUAoFoAAAAeAR0AvFLQHiC4KFVAoFoAAAAeAAAA/ABUWC1TUjY3NCAgICAgAAAA/QAYSxpRFwAKICAgICAgAYYCAy7xTpABAwQFEhMUDx4fICEiLwl/Bw8fBxcHODcHMD8HwINPAABmAwwAEgCAAR2AGHEcFiBYLCUAoFoAAACeAR2A0HIcFiAQLCWAoFoAAACeAjqAGHE4LUBYLEUAoFoAAAAe1gmAoCDgLRAIYCIAgOAhCAgYAAAAAAAAAAAA1A== + DRM.card0.HDMI_Type_A.2: + status: disconnected + enabled: disabled + dpms: On + modes: + edid-base64: + DRM.card0.VGA.1: + status: disconnected + enabled: disabled + dpms: On + modes: + edid-base64: + DistroRelease: Ubuntu 10.10 + InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) + Package: xserver-xorg-video-intel 2:2.12.0-1ubuntu5.1 + PackageArchitecture: amd64 + ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.35-23-generic root=UUID=f58ae567-8564-483f-a333-2e09fd73ebfa ro quiet splash + ProcEnviron: + LANG=en_US.utf8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.35-23.41-generic 2.6.35.7 + Tags: maverick maverick + Uname: Linux 2.6.35-23-generic x86_64 + UserGroups: adm admin cdrom dialout lpadmin mythtv plugdev sambashare + dmi.bios.date: 10/18/2010 + dmi.bios.vendor: Intel Corp. + dmi.bios.version: TCIBX10H.86A.0040.2010.1018.1100 + dmi.board.asset.tag: To be filled by O.E.M. + dmi.board.name: DH55HC + dmi.board.vendor: Intel Corporation + dmi.board.version: AAE70933-501 + dmi.chassis.type: 3 + dmi.modalias: dmi:bvnIntelCorp.:bvrTCIBX10H.86A.0040.2010.1018.1100:bd10/18/2010:svn:pn:pvr:rvnIntelCorporation:rnDH55HC:rvrAAE70933-501:cvn:ct3:cvr: + glxinfo: Error: [Errno 2] No such file or directory + system: + distro: Ubuntu + codename: maverick + architecture: x86_64 + kernel: 2.6.35-23-generic ** Attachment added: "BootDmesg.txt" https://bugs.edge.launchpad.net/bugs/572139/+attachment/1770901/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/572139 Title: Samsung LE-46B530 TV does not work with Intel DH55HC motherboard -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
