Post subject:  Setting to force Video to Upscale from an SD size?
I just got this new LCD Display.
If I set my Modeline and resolution to the native of the TV then Knoppmyth scales the Recordings to the appropriate size and they look great for old SD recordings. Screen is full and there is no overscan or black bars.

The only issue with this, All of my Recorded and saved Videos that are now over in the Video section will only display in a 4:3 boxed format. The TV can do some scaling too, but it can't compensate for this issue as the display is native screen size and the box is inside that.

If I decrease the resolution back to 1024x768 then I can use the TV scaling to bring these to full screen, however the results are less than above for the Recordings.

So back to the subject, is there a setting I can run in the video player (I am using the mplayer) to force it to run these videos as something other than 4:3.

Videos are old and newly selected Holiday shows as an example.
I only have available Satellite feeds so I am in SD resolution, that won't change for a while.

TV is a Sony KDL 40S3000 - 1366x768 res, 720p or 1080i being fed through HDMI from the DVI output on my XFX fx62000 video card on the Slave frontend.

Any other particulars I can provide?

TIA.

mplayer can scale or stretch the recordings for you. Use the 'w' key to cycle through the different widescreen modes. You can also use your remote to pull up the onscreen menu and select the widescreen mode from the menu.

Have you tried to use the internal player for video playback instead of mplayer?

It will scale just like when you are viewing a recording.

If you want to give it a try. Go into settings/video and there will a player start command. Change it from mplayer to internall (no switches needed).

Take note of you original settings incase you want to revert back.

ok, I saved my previous settings and then changed to Internal for the player.

That allows me to scale video with the W key or change aspect with the menu from the remote.
It isn't perfect, but overall the picture is better with the TV running at it's native resolution.

So basically this is sort of solved. I have found any issues why I need to go back to the mplayer line.

Thanks

Can you please post your modeline and anything else in xorg.conf that is relevant.

I am at the same place.

I did a bunch of research on the Web and finally came up with a modeline that was for a very similar model of Sony TV as mine.

That required me to change some lines in my xorg.conf
First I created a copy of my existing xorg.conf
Code:
#cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig


Then I edited the xorg.conf.
Code:
#nano /etc/X11/xorg.conf

In Section "Monitor"
Commented out existing refresh and inserted:
First 2 are marked as "Sony Tweak"
# HorizSync 28.0 - 78.0 # Warning: This may fry very old Monitors
# HorizSync 28.0 - 96.0 # Warning: This may fry old Monitors
HorizSync 30-66 #Sony Tweak
# VertRefresh 50.0 - 75.0 # Very conservative. May flicker.
# VertRefresh 50.0 - 62.0 # Extreme conservative. Will flicker. TFT default.
VertRefresh 30-61 #Sony Tweak

Then further down inserted the following 2 lines.
#Modeline "1360x768" 85.500 1360 1432 1544 1792 768 771 777 795 Sony Tweak
Modeline "1360x768" 85.500 1360 1432 1544 1792 768 771 777 795

Finally down in the Section "Screen"

I modifed each of the lines in there to show the 1360X768 Resolution.

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultColorDepth 24
SubSection "Display"
Depth 1
Modes "1360x768" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1360x768" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8

EndSubSection
SubSection "Display"

EndSubSection
SubSection "Display"
Depth 16
Modes "1360x768" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1360x768" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 32
Modes "1360x768" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Now I did find several discussions to use 720p for the Modeline, But I couldn't seem to make that work or find a corresponding setup in the Modelines for that mode.

This works on my Sony KDL 40S3000 tv, which is 720p/1080i with a screen resolution of 1366x768. There is discussion of using the next higher multiple of "8" rather than 1360x768 but I haven't tried that yet. Too many "projects" if you know what I mean.

hth, it works for me. If you need anything else just post in here.

G'day bigbro.

What other setting and or tweaks did you make.

I now have my sony lcd screen running but the quality seems less than the pvr-350 over s-video.

I don't think it is the capture, since it look OK on my pc via a crt.

I need to have a look a dvd and see what that is like, but I suspect I need to do some more tweaks to get 'right'

I have a Sony and auto configure worked with it. As root:
Code:
dpkg-reconfigure xserver-xorg
Make sure you have the correct video drivers!

For me, the LCD would display the resolution when it first starts up, so I could tell when it was working correctly. If your display doesn't do that, check /var/log/Xorg.0.log. Look for "Virtual" (as in Virtual Resolution). This should be the resolution of your display. Note that this isn't the perfect way to determine it, but I found the modeline errors in the log file not very obvious and a small virtual resolution was the best indicator that it went wrong....
