Bug Screen stretched and cut
#1
Dear community,

I ran into an annoying bug which totally breaks XBMC/Kodi for me.

Currently I am running XBMC on two pi with Openelec, on my two mac and on a Zotac id HD40 with ION.
Everything worked great until I got a new TV (Samsung F6100)
When I connect the Zotac to my new TV running the latest XBMCBuntu or Openelec then the screen is extremely stretched and cut.
When I connect it to another TV/monitor the picture is adjusted right.

I do not get the same problem with when I connect a Raspberry Pi on the Samsung F6100.
Strangely when I use an older version of Openelec (3.2.4) the pictures is as it's supposed to be.

After googling this problem I found a thread on the openelec forum with a work around.

http://openelec.tv/forum/67-display/6926...mitstart=0

Is this a known problem and is someone working on this?

Currently I am running Openelec 3.2.4 again but I would prefer to use gotham again as soon as possible.

Any help appreciated.

Turn off Underscan with your TV's remote. It's a TV setting.

The mode is called "Just Scan", "Fixed", ...
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Thank you for your suggestion but sadly this is not it.
It was the first thing I have tried.

This is what it looks like.

It seems to be some problem with how nvidia reads the edid of some TVs.

Changing the resolution does not make a difference.

Somebody on the openelec forum with the same problem pointed out that when he compared the Xorg logs from 3.2.4 and 4.0.3. The only difference in the modes are the viewport offsets.

Make a xorg.conf that works?

Please post your configuration details there to increase the pressure on nvidia.

Thank you.

Thank you for the link.
I have added my set up and it looks like it is a specific problem with some TVs.
