Yes, this is why those options exist. Make sure to disable the "Use DXVA chroma upscaling..." trade quality for performance options.

HDR questions

Hi guys, hi madshi!

Can you please comment how HDR meta is used when playing a HDR video? Are HDR mastering primaries/luminance from the video sent to the display or some static values are used?

Any chance we'll see HDR support in madTPG in near future?

Thanks in advance!

P.S. madVR is great.

Is there any reason for upgrade Windows 7 to Windows 8.1 for using Madvr?
Madshi used to say that 8.1 is better then 10. And what about 7?

Desktop Composition on 8.1 is far better then on 7. Not sure I would upgrade for that alone, but its definitely a plus.

I do not have any problems with 24 and 60Hz content using W7 (AMD drivers).
Will I have some using W8.1?

huhn, why do you recommend FSE for windows 7? What about windowed overlay?

because FSE works on any GPU. generally nothing wrong with overlay.

Has anything changed lately with madTPG? I use both Calman and LightSpace via a laptop to calibrate my Sony 940E HDR display using madTPG as the pattern generator on my HTPC. With both programs this evening, madTPG would disconnect randomly in the middle of taking reads. My network is solid and did not drop, so i am not sure what is causing this behavior. Being that this behavior is happening with both Calman and Light Space, makes me think the issue is with madTPG. Calman, Light Space and madvr are all on the latest version.

I re-calibrated recently using v0.91.11 madTPG and CalMAN (5.7.2.61). I don't think anything is wrong with madTPG.

3d playback

Hi,

I have started using madvr for stereoscopic 3d playback with good results. The problem is 3d gets enabled on my television even when a 2D file (of 1080p resolution) is played. I have to manually disable nvidia stereoscopic 3D to get normal 2D playback. I am on a gtx 1080 (Win10 - 378.92 for hdr playback which works fine). Is there some way i can configure madvr to only trigger 3D on display when a 3D file is playing.

Thanks.

Edit: I am not using Nvidia 3D play, just the vanilla drivers for stereoscopic 3D

Quick question regarding 3D LUT calibration: what is the best practice for calibrating a projector? Using fullscreen patterns or windowed patterns (with black desktop on the background)? I guess the extra light in the room when using fullscreen patterns have an impact on measurements. I have the feeling that windowed patterns better render actual playback.

I understand that total light into the sensor is important for accuracy and the intensity of light reflected not off the screen should be low and largely match the color of the pattern.

Full screen patters are recommended, unless the display changes brightness based on total photons out (e.g. plasma).

It's not a madVR crash, it's a system crash. You won't get any help here.

Send the report (I'll assume you have already) and post a bug report
