The very purpose of madVR is to bypass most of the graphics card driver's video picture processing to guarantee a consistent picture quality.
In your described scenario you would have exactly the same quality.

Is this a trick question? There would be zero difference imo.

Upgrading a video card provides more capability. If you don't utilize the capability, nothing has changed. In other words, I doubt replacing a GT630 with a GT740 and playing the same non-problematic title is going to look any different than it did provided all you did is swap the cards.

Cheers lads!

No, not a trick question!

Yeah, I have a DELL Dimension 9150 (with a GT630) as a HTPC, since all the material I watch is just 720p anyway. The picture is great, btw!

I also have a DELL Dimension E521 (with a GT740) in reserve.

I wonder what would happen, to the picture, if I needed to change out the graphics card and take the GT740 and put in the Dimension 9150?

Or the other way around (what would happen to the picture) if I needed to take the GT630 and put in the Dimension E521?

Due to their age, I mean - and using the same TV.

What you guys are basically saying is, that - should either of these scenarios occur, I would still have the same picture with the same TV?

Yep, everything should look exactly the same.

What's the difference between OS HDR (Windows 10 HDR enabled playback) and NV HDR (MadVR auto switching with Windows 10 HDR turned off)?

I red some about OS HDR not sending metadata back in early 2018s, but some people claim it does.

Are they basically both the same but one is rendered by Windows and one by Nvidia?

I imagine that the "2.35:1 35mm film" sign tells me that black bar detection is actived ...



The strange thing is that I still have black bar detection also if I change "hardware decoder to use" to none or D3D11.
Is it not only a feature of DXVA2 copyback?

What exact values do you have in madVR for display resolutions switching?
This is a new photo taken now with the file not paused, during playback.



In the settings for devices into Madvr I've setted: 2160p23, 2160p24, 2160p50, 2160p60.

Chors , trust me, the frame lost are massive. This is not a refresh problem ... Look at the decoder queue ... it's to low.
Huhn is right , my GTX970 has a poor decoder for UHD files!

I've also problems with 24fps UHD HDR files taken from UHD discs.
If I play the file from the beginning the queue remains full and I've no drop frames with a avg rendering time near 32ms.
If I move ahead using the line-time of the film and jump to another point It starts to drop frames massively.
If I pause the playback the rendering queue fills up again and if I play it again I have no dropped frames for some minutes .... after that maybe the queue turns down and the drop frames restarts.

In a first moment I was thinking that my USB3 HDD was to slow to send MKV UHD files to HTPC. So I've copied a file to the main SSD hdd.
The problem persists so I'm thinking that Huhm is right my GTX970 has poor decoder also for UHD at 24fps.

P.s. Focus assist is disabled.

If you have any suggestion to reduce dropped frames ...

Thank you so much.

Are there any disadvantages of using the internal subtitle renderer inside MPC_HC for Madvr instead of using xysubfilter?

Yes it switch to 1080p24 but in full screen exclusive mode it drops a lot of frames with 3D MVC mkvs, without exclusive mode it works fine

They are the same, but one is automatic and the other isn't.

The OSD says the GPU can't keep up, so I don't know what the problem would be. Try reducing your setting for chroma upscaling and see if the rendering times come down. There must be some sort of bottleneck causing those rendering times. fullscreen exclusive mode isn't reliable on Windows 10. That is most likely the issue.

The only benefit for 8 bit panels and fullscreen exclusive mode is the removal of unwanted pop up messages from win.Am I right?

You can also use Quiet Hours / Focus Assist to hide notifications.

I don't think auto engage vs manual is the only difference when using NV HDR vs OS HDR.

OS HDR does not apply at display level through any player or software. NV HDR does. This means the display is not going to enter an HDR mode that auto adjusts settings like contrast and backlight because it doesn't passthrough anything to the display other than the desktop faux HDR.

I seem to remember madshi saying that fullscreen windowed is the way to go with Win 10.

Use FSE for frame packed MVC 3D.
Use FSE for UHD HDR.
Use FSW for everything else.

Focus Assist does not play well with madVR. Oddly it causes studder if any aspect of it is enabled.

Some people back in the thread said that OS HDR doesnt't send metadata.

Then there's also NV HDR sending 12bit image while OS HDR maxes out at 10?

madVR is limited to 10 bit output no matter what.

the GPU driver is limited to 12 bit for the usual refreshrates/resolutions.

the HDR NV API or the HDR OS API have nothing todo with this.
