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


Connected to a Nvidia 7300GT with an DVI to HDMI cable.  
Connected to a Nvidia 8400 GS with an DVI to HDMI cable.  


''NOTE that the 50 Hz modelines will probably not work if you try to connect to a non-HDMI port on the Sony TV (i.e. the PC input).  The Sony KDL-46WE5 which is supposed to be very similar to this model would not display 1920x1080 50Hz modelines when connected to the PC input on the TV.  This was using a VGA DB15 video cable attached to a DVI-DB15 converter (graphics card in my PC has 2xDVI ports).  Once an DVI-HDMI converter and HDMI cable was used then the 50Hz modelines worked properly. The Sony manual has a single supported graphics modes table for the PC and HDMI inputs- this would lead you to believe that PC input and the HDMI inputs all support the same graphics modes but they don't. (Indulis' experience)''


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 and changed/added the folowing lines :
'''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        "UseEDIDDpi" "false"
Line 21: Line 25:


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

== 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"

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"

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.
