How can i switch to 1980x1080@24Hz

Max pixelclock (you can get this the xorg log file)

Thanks, I will look into it this weekend!

For starters, it's a Samsung 46" LE46A686 LCD-TV, I'll have to check the other specs. Can I do this using Powerstrip in Windows?

Yes,I guess you should be able to.I don't know that application so I can't tell you for sure.
I got my info from the xorg log file (max pixelclock, this is a video card parameter) and from the TV manual (horizontal sync,vertical refresh).

Hi! Could you help me out generating a 1080p modeline for my tv?

I have a panasonic TH-42PZ70EA, xbmc can´t detect the edid

Max pixelclock = 165 MHz
HorizSync (minimum and maximum) = 31 - 69 kHz
VertRefresh (minimum and maximum) = 59 - 86 Hz

106 cm (diagonal)
922 mm (S) × 518 mm (H)

My tv handles:
1 125 (1 080) / 60p
1 125 (1 080) / 50p

It should also be able to use 24p.

Thanks!

IMPORTANT: I've had several issues with nvidia drivers and/or xbmc version. So this is my tested and verified combination what works without issues for me:

* xbmc live 9.04
* nvifia drivers 180.44



Your TV will not be able to do 24p ,look at your vertical refresh it's 59-86. So it's similar to my TV which means you can get 1080p@60.

Try my xorg.conf with the above combination of xbmc live and nvidia driver.Your TV has the same data as mine,so can't see why it shouldn't work out.Use the whole section from my conf file :

hi there can you plss help me too?



the television is a panasonic th-42pz 80 and is capble of 1920x1080@60 hz or 24 hz

many thanx in advance !!!

Thanks!

I will try this tonight. I´ve seen posts one avsforum that my V can handle 24p with a mild "judder". Still it´s probably better to use 1080p@60.

btw, is it always better to use 1080p@60 instead of 1080p@50?
I´mthinking that it could depend on what material you are playing.

Folks, you do NOT need a modeline in xorg.conf. My Panasonic 46PZ80 is happily running 24p 1080p without a modeline. Played around with it first but it wasn't needed.
Make sure you have:

Option "DynamicTwinView" "false"

in your xorg.conf among your "Screen" section options.
Then enable "adjust refresh rate" in xbmc, settings, video, player ....
And enjoy 24p output. Check the output refresh rate while playing a video with pressing "z" on your keyboard ....

Edit: and make sure xrandr is available on your linux installation. XBMC will use it to auto adjust refresh rates.

This is exciting information! I will try this.

But could it be so that it´s working for you because "xbmc live" can detect your TV´s EDID properly?

Is Option "DynamicTwinView" "false" the only thing that you have modified in xorg.conf, what about vertical and horizontal refresh rates?

Br, Daniel

I can post my xorg.conf tonight when I am home. I am not using xbmc live but the latest svn revision ... not sure if I disabled EDID in xorg.conf or not. Will let you know.
