Guide: Perfect playback & Display calibration (4 Viewers)

thanks for above

I'm guessing that for TV's this is the scaling that you would expect to see:

Will have to wait and see from people who have Intel HD Graphics with a TV attached.

#just tried to get a picture for you, but even connected to my tv using the dsub output i get no settings in the tv/monitor section so cant help any further sorry.[DOUBLEPOST=1371560756][/DOUBLEPOST]

The wiki for MPAR says "The MediaPortal Audio Renderer is able to encode the audio again to AC3 . . ."Is that true?

Yes

when playing 23.976 material, I get tearing near the bottom of the screen.

Use vsync forced always on in display driver settings.
timestretch + sync in mpar settings
as per guide.

If still problems. Increase HT speed + VGA core speed in bios. HT speed will have most effect on your integrated hd3200.

@kiwijunglist: Thanks a lot for this awesome tutorial.. You're really helping the comunity a lot with this, including myself.. Really cool to expiriment with this settings!!

@Lyfesaver74: Maybe nice to report this thread to our Facebookfriends?

1. If we set v-sync in display settings to application "off/on, unless application specifies" will it turn v-sync on in MP. ie, does MP ask for v-sync

For windowed mode applications AERO will be still syncking to v-sync, it would only apply to full screen mode. Generally there is no reason to turn v-sync option of from the GPU drivers (unles to try to troubleshoot some issues on driver side).

2. Is force v-sync needed in display settings if we use v-sync in MPAR? Does it cause any harm?

No, actually something must have v-sync on EVR side to allow it to report the v-sync position. So it is actually needed to have v-sync enabled (as far as I know 1.4.0 changed in such way that full screen rendering mode is a real full screen mode so AERO wont do the sync anymore).

It is not realy clear for my, why I sould use MPA.

I've got perfect 23.97Hz playback with my AMD HD7750 and LAV (absolute flat lines and not one drop with a 3.5 hour movie).

done

In your situation any improvement would be negligible, you can post a screenshot with shift+1. You will notice that measured refresh rate is never *exactly* the same as the fps, so you will experience slightly more drift and more frequent corrections without MPAR.[DOUBLEPOST=1371600383][/DOUBLEPOST]@tourettes but i asked, does MP ask for v-sync?

In fullscreen EVR, does MP request vsync. We have multiple vsync modes, currently I recommend people to use force vsync for ALL apps. But this affects apps outside MediaPortal (Although it probably doesn't matter), was more out of interest.

No, actually something must have v-sync on EVR side to allow it to report the v-sync position. So it is actually needed to have v-sync enabled (as far as I know 1.4.0 changed in such way that full screen rendering mode is a real full screen mode so AERO wont do the sync anymore).

Thanks this is useful. Some people reporting tearing still with vsync enabled, this sounds fishy to me. Do you think these people would benefit from triple buffering? as far as I understand it puts 3 frames into the buffer prior to displaying a frame. Will buffering the frames mess with MPAR?

If I follow this thread's recommendations, I get stereo if I select stereo in LAV's mixing, and I get no sound at all if I select 5.1. . .

So I do not use MPAR, and do use LAV's bitstreaming, which works fine for audio. But when playing 23.976 material, I get tearing near the bottom of the screen.

I guess I wasn't clear. I never get Dolby Digital when using MPAR -- I get either stereo or nothing. When I don't use MPAR, I do get AC3 and DTS via bitstreaming.

Since MPAR reconstructs Dolby Digital, is there something else that would prevent it from being delivered to the AVR? (The mixing, perhaps?)

I will be updating to 1.4.0 any minute, so I'll retest at that time.

 

[kiwijunglist]

You only asked if MPAR can decode + re-encode AC3, it can Try force AC3 in MPAR. Sounds like your receiver doesn't support many PCM formats perhaps, This is not really an audio support thread, so I don't know. Maybe post in another thread?

Vertical Sync off = Tearing
FPS:Refresh rate miss-matching = Stutter / repeated frames
Under powered hardware = dropped frames (which looks like stutter)

Can you post screenshot of above with

Override sharpness + sharpness set to zero
Override noise reduction + noisereduction set to zero
Film mode = off
Preview = off

Thanks.
