** Description changed: - I'm running current release of Lucid Lynx desktop version and trying to - use 1080p with this TV. + 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. 60Hz and 1080p are selected. + " Onkyo 7" " text shown in display settings. 2. Connect HDMI from motherboard directly to TV: - " Samsung 7 " text shown in display settings. 60Hz and 1080p are selected. + " 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. - - Same also happens with Mythbuntu 10.04 I'm planning to use. - - The TV shows correct 100% screen coverage in the BIOS so no problems - there. In BIOS the resolution is 800x600, however. - - When checking with Mythbuntu (Appearance Wizard) the resolutions are as follows: - 1920 x 1080 (TV) -> 1680 x 900 (Ubuntu) - 1280 x 720 (TV) -> 1120 x 600 (Ubuntu) + 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) Incorrect resolutions, - 2) "Searching for Signals" problem: it starts when scrolling in Firefox or moving windows, - 3) Flickering problem, the picture "tears", this may include behavior 2. + 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 symptom 3 may disappear if moving the window back, but it starts again especially if window is on the border of the screen. + 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. - Update: FYI no HDMI audio with this setup but this seems to be covered - already in other bug reports. + 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.
