Usage Information

I am using an European version this TV and will try to describe problems I have here.

Connected to a Nvidia 8400 GS with an DVI to HDMI cable.


10th July 2012 - Currently I am using the judderfree solution further down with 0810


I was not able to get the AV Wizard to setup the TV to 1080p with 50hz, so I setup 1080p and 60hz. Then afterwards I changed the xorg.conf and changed/added the following lines : 

Option         "UseEDIDDpi" "false"
Option         "UseEDID" "true"

Modes           "1920x1080_50_1" "1920x1080_50_0" "1920x1080_50" "1920x1080" "1920x1080_50i"
VertRefresh     49-51

and rebooted. After that I had 50hz.

The line "1920x1080_50" uses the EDID information it gets of the TV and sets things up correctly. In the /var/log/Xorg.0.log you can then see that it chooses the right resolution.

"UseEDIDDpi" "false" is important, otherwise you will get very small unreadable characters.


I did also start KDE and then start nvidia-settings. Then below OpenGL settings activated the checkbox next to "Sync to VBlank" so that it is used.

Then in MythTV (see here http://www.mythtv.org/wiki/VDPAU#Enabling_VDPAU_in_MythFrontend) under "Utilities -> Setup -> TV Settings -> Playback -> Playback Profiles (3/8)" setup "VDPAU Normal"


Update 20.07.2012 for Judderfree is this also needed : http://www.mythtv.org/wiki/VDPAU#Tearing.2FStuttering Change Option "Composite" "true" in /etc/X11/xorg.conf to "Disable": 

  Section "Extensions"
      Option "Composite" "Disable"
  EndSection


Judder free TV and Video with MythTV and MythTV video plugin

10th July 2012 - This is the CURRENT solution I am using with 0810


Using the description from here : http://www.mythtv.org/wiki/User_Manual:JudderFree

IMPORTANT is in your xorg.conf to change the Option "DynamicTwinView" to "true" !!! That is the option that lets you choose ALL the refresh rates, also the 23.97 !

I did setup all the needed resolutions and changed MythTV to change the resolution as described in the link above. The xorg.conf from below works with that!!!

That way MýthTV's Video plugin will change the refresh rate to the right typ, no matter what kind of material you are playing. Execpt for PAL DVD's , they are for some reason set to NTSC 59.96 rate. I have no idea why at the monent.

I have still setup the VDPAU things above in mythtv and "vsync to blanc" nvidia-settings !!

And this is also needed : http://www.mythtv.org/wiki/VDPAU#Tearing.2FStuttering Change Option "Composite" "true" in /etc/X11/xorg.conf to "Disable": 

  Section "Extensions"
      Option "Composite" "Disable"
  EndSection



Alternate solution (I used first)

I was not able to get the TV setup to 1080p with 50hz, so I choosed 1080p and 60hz. Then afterwards I changed the xorg.conf to the right 1080p@50hz Modeline i found in the HDTV list in the MythTV modeline database. 

       # 1920x1080 @ 50 Hz (EDID) HSync: 56.25 kHz
       ModeLine "1920x1080" 148.50 1920 2448 2496 2640 1080 1084 1089 1125 +HSync +VSync

And changed the VertRefresh to : 

       VertRefresh     49-51

and rebooted. After that I had 50hz.
