Hi there,

I've a problem with the setup mentioned in the topic and I'm running out of ideas ;( Maybe one of you can help me or at least give me some hints what to do ... Well as you can imagine I'm using openchrome as driver for my graphics card. My Mainboard is the via epia SN18000G vith VIA VT8251 South Bridge and CN896 North Bridge.

(http://www.via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=550)

I've played a lot to get Xorg running a now it basically is, BUT with some problems. i want to connect my LCD TV Screen to be used as monitor. The TV's user manual says that the resolution is 1366x768 with 60Hz.

within the xorg log file I can see this:

 Hz

7
 which is the supported resolution according to edid (?)



I also should mention that I need to use the
     Option          "DDC" "false"
within the Screen Section of xorg.conf. Otherwise I only get

(**) CHROME(0): *Mode "1280x720": 59.4 MHz (scaled from 0.0 MHz), 37.9 kHz, 50.1 (II) CHROME(0): Modeline "1280x720" 59.42 1280 1312 1536 1568 720 735 741 75 If I use the modeline manually (or another one for [EMAIL PROTECTED]) the resolution is ok but I get some kind of flickering. If I don't use any modeline the resolution is at 1280x720 according to xvidtune but the picture is not fitting the monitor. it seems to feel that my screen is bigger in either direction as it actually is. but there is no flickering ...

1024x768.

I really can't remember what I've already tried ... way too much ;)
Does anyone have any idea?

Thanks a lot

How is your TV connected to the board ?

Xavier

Please post your xorg conf and xorg log (compressed). My bet would be either you are using Option "VBEModes" either you are using Option "ActiveDevice" "LCD".

Hi,



thanks

TV is connected via VGA cable. I've used both settings during my experiments with xorg, but right now it's not included anymore. It's now stripped down to a very basic and simple xorg.conf (see attached)

does anyone have some hints for me? ;)

The conf looks good.
How did you generate your modeline ? I suggest using cvt.

Did you try with 1366x768 ? 1366x768 with reduced blanking ?

Regards,
Xavier

Did you try with a reduced blanking modeline ? ( This needs an additional option in the xorg conf, something like "ReduceAllowed", serach the mailing lists' archives).

hi,

yeah I did try with 1366x768 but not with reduced blanking ... will try this 
tonight when I'm back home.

thanks

Hi,

thanks again for the idea but it's still not working ;(





I'm getting really furstrated ;)

Does anyone have _any_ idea?

thanks

If I use the config attached I still have the problem with the "big picture". The modeline I use there was generated by cvt with the -r option. If I uncomment the Horisync and VertRefresh Option I get the flickering again and the picture is only cut off at the right and left border (upper and lower border of the screen seem to be ok). If I use the "normal" 1280x720 modeline I'm just getting a resolution of 1024x768 ...
