| media | hey all... can anyone direct me to a channel that might be able to help me figure out connecting to a tv through hdmi | 00:12 |
|---|---|---|
| media | i'm having a problem with it | 00:13 |
| media | something to do with edid... | 00:13 |
| media | thanks | 00:13 |
| genii-around | media: Are you using hdmi-hdmi cable or some converter in between? If there is a dvi-hdmi converter then often the os cannot query the tv/monitor for it's capabilities | 00:18 |
| media | its a straight hdmi>hdmi | 00:26 |
| media | any ideas? | 00:27 |
| genii-around | Anyhow.. might want to look into using xrandr to explicitly change the mode for what is probably the HDMI-0 device... some reference material: https://wiki.ubuntu.com/X/Config/HDMI http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.htm | 00:30 |
| media | appreciated. thanks | 00:30 |
| genii-around | np | 00:32 |
| media | whoops... second link 404'd | 00:32 |
| media | what does it mean to "change the mode"? | 00:34 |
| genii-around | media: The text of the second link copied into pastebin: http://pastebin.com/yB1XuTJA | 00:34 |
| genii-around | media: Usually you will not for instance be using 1920x1080 on your computer monitor, so you use xrandr to set that mode ( or resolution if you prefer) | 00:35 |
| media | i'm getting the correct resolution... the problem is with weird colours and periodic flickering | 00:36 |
| genii-around | What is the result from just: xrandr on the command line? Might be at 50Hz or some odd refresh | 00:39 |
| media | Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096 | 00:40 |
| media | VGA1 disconnected (normal left inverted right x axis y axis) | 00:40 |
| media | HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 698mm x 392mm | 00:40 |
| media | 1920x1080 60.0*+ | 00:40 |
| media | 1280x720 60.0 | 00:40 |
| media | thats what comes up | 00:40 |
| media | the flickering only happens every 5 minutes or so | 00:40 |
| media | its very odd... | 00:40 |
| genii-around | Yes | 00:40 |
| media | i think it has something to do with edid tables... | 00:41 |
| media | do you know anything about that? | 00:41 |
| media | its a term that came up a bunch during my search | 00:41 |
| genii-around | I doubt it has much to do with that. The edid is just the information which the monitor/tv reports back to the computer when it's asked what it's capabilities are | 00:43 |
| genii-around | You're already using 1920x1080@60Hz so it must have been able to understand the tv could use it | 00:43 |
| media | ok. i understand | 00:44 |
| media | any other thoughts? | 00:45 |
| genii-around | The flickering happens if the computer is just sitting there with maybe a webpage or not doing anything, or it happens when you are streaming video to the tv from the computer? | 00:46 |
| genii-around | ( because ext filesystem will "hiccup" a bit when streaming large files | 00:46 |
| media | i dont think its that... i can fix the flickering by changing the video input on the TV to something else | 00:47 |
| genii-around | Perhaps try querying the tv for it's EDID info... first make sure package read-edid is installed... then: get-edid|parse-edid | 00:52 |
| genii-around | sudo may be required for the get-edid | 00:53 |
| media | et-edid: get-edid version 2.0.0 | 00:54 |

| genii-around | Hm | 00:55 |
| genii-around | I'm out of immediate ideas | 00:57 |
| media_ | i see... ideas on where i might go next? | 00:59 |
| * genii-around has another coffee and thinks\\ | 01:01 | |
| media_ | no one is responding in the xbmc-linux channel | 01:02 |
| genii-around | There may be some intel driver option for the xorg.conf which is helpful, but offhand I would not know which one(s) | 01:05 |
| media_ | ok thanks anyway. take care | 01:07 |
