Hi All,

I am using an edid.bin in my xorg file, reason being is that sometimes my revo switches on before my amp/tv and results in X failing to initialize.

Is there a way to have custom ModeLines ie;

ModeLine "1920x1080_23.976" 74.175 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync

when you have edid.bin specified, ie:

Option "ConnectedMonitor" "DFP-0"
Option "CustomEDID" "DFP-0:/storage/.config/edid.bin"
Option "IgnoreEDID" "false"
Option "UseEDID" "true"

Hello all,

I`ve been having a wierd problem with the nvidia and 23.976 playback. I own an viera plasma, and a pc is connected to it with an gt210 nvidia card. I run ubuntu 12.04 as a OS, and use the latest Nvidia drivers available 310.19.
I`ve followed this howto, and everything seems fine: i have 60 hz in xbmc front interface and when a 23.976 movie is playing it switches the display into "24Hz" mode.
The problem is that when i have the frequency set to 50 or 60 Hz and then i switch to match video refresrate, the resolution changes from 1920x1080 to 1917x1020. This only happens when i switch, because if a put the default refresh brate to 24Hz from the begginging(frontend and movies) then everything is normal. Does anybody knows or has any fix for this issue?

Why did you follow this how-to? I have added a big fat OUTDATED to post #1.

As a thread for HOW-to, it is outdated as Fernetmenta says. Look at my signature (last link though that applies to Full HD only), until I have time and patience to re-write This subject on a forum topic that would replace this. this thread is ginormous anyway. Good luck finding anything in between the gazillions replies of value.

for time being as a stop gap for discussing this matter this is probably best place as long as ppl dont use the how-to.

@FernetMenta

Increase fond size and bold it and color it This color

Perhaps it wont be so easily ignored after that?

* un1versal giggles @ Fernet's comment.

Sorry I know its a serious comment, but its funny as hell. Big Grin

Does anything of this still apply for latest drivers (for example 304.84 as included in OpenELEC)? Or does it get handled correctly out of the box by now?

I am using a Shuttle XS35GTV2 with an ION2.

Thanks!

I am wondering too because I've recently been re-experiencing some synchronization weirdness with OpenElec. I do note that after a fresh install of OpenElec 3.0.4 that a custom xorg.conf is no longer needed for my display timings to be set up properly at 23.976 but I do notice what I would call "micro stuttering" in video content that's a bit distracting (and this has continued with 3.0.5).

Also, with the latest build I've been noticing what sounds like a bit of "noise" in the HD audio playback. I use the sync to display option and match refresh rate to source and this static noise has not been a problem before.

FernetMenta · 2013-06-14, 18:56

This entire thread is outdated as mentioned above. A custom modeline for 23.976 is still needed, otherwise you'll get 23.971.

Audio engine is a different story. Currently I am working on a new engine.

**voip-ninja** · 2013-06-14, 19:06

Interesting, I will have to review the thread and update my xorg.conf appropriately. If you happen to have a pointer towards modification of the xorg.conf for proper 23.976 playback I would really appreciate it.

FernetMenta · 2013-06-14, 19:36

Here is a xorg.conf I use on a single monitor system: http://www.xbmclogs.com/show.php?id=28096
You may need to change DFP-1 in the "Screen" section to a value appropriate to your system.

**voip-ninja** · 2013-06-14, 21:22

Thank you, I will take a look and try to implement this on my openelec implementation.

**voip-ninja** · 2013-06-14, 22:54

Thanks again, I did have to make some modifications (scratched my head a bit about xserver not starting the display and realized with HDMI that I needed to modify the xorg.conf to HDMI-0) and now it's working.

Polling with xbmc-randr shows I am getting 23.976 playback now. You are right, it was 23.971 before.

I am a bit curious, I tried the "nvidia" custom xorg.conf file on the openelec page and it did not work.... haven't had time to investigate. I am wondering what some of the "Nvidia" centric options are in that xorg.conf file... things such as "coolbits" etc. Any insight on that stuff would be useful I think.

The "custom" xorg.conf on the OpenElec page is here and has a TON of Nvidia options set.

What I am using right now looks like this;

Looks like I'm still not getting "perfect" playback of 23.976 as I can see audio engine is duplicating a packet every 13 minutes.

Any thoughts on further improving it? The video card is a GT430
