So, that's perfect! That's how you can test what you want, if the 720p video is fullscreen on your TV (which probably is).
Since your TV native resolution is 1080p and you feed it with 720p and since it's fullscreen -> your TV is doing the upscaling from 720p to 1080p. That's it.
Now, if you wan to ask then how can you compare 1080p upscaling: the answer is you can't.


You can't. It has to be at least chroma upscaling. What you can do is:
- 1. set the chroma upscaling to a fast (although dumb) one, e.g. bicubic 50
- 2.a. (as you suggested below) play only content (720p/1080p) that what your resolution is
- 2.b. or manually switch the resolution before you start one (I'm not sure you can do this automatically)

Sorry, I tried only a file which had black borders and this showed me a video "not in fullscreen"; how unlucky!
Then I tried another file but the TV at 720p cut some borders! (in ctrl+j: Movie Resolution=704x576 and Target Rectangle=0,0,1280,720)
Weird thing is that this same file at 1080p shows in ctrl+j: Mov Res=720x576! This is weird, right?
Right now I can't control, but I'm quite sure I have "touch from inside" option, if it matters.

Thank you for bearing with me!

you first need to wait for a way to decrypt the disc.

but after this there is most likely a way to play these files back even on an SDR 1080p screen.

BTW. 48 hz is not part of the UBD and hdmi 2.0 spec.

sorry I meant HDR which is supposed to require HDMI 2.0a. so in that case a new graphic card with 2.0a support would be needed?

[huhn]

madshi said he want to send it as normal "gamma" so no.

but you need an nvidia card for 60 FPS UHD output. and an nvidia maxwell card for UHD 4:4:4 at 60 HZ.

Well, to be honest, I think same way for Win8(.1). Something like Vista, but not that bad.

You said that Win8.1 is better for madVR then Win7. Can you provide more details?

desktop composition is broken on windows 7/vista. it's trivial to get an composition mismatch on these operation systems which results in a lot of playback issues.

this issue is fixed with windows 8+

[huhn]

can someone with an AMD card and crimson driver test deinterlacing?

in my test it looks like this driver uses NN bob or something terrible like this...

I'm not into this that much, so I have to ask.
How desktop composition has an effect on madvr ?
I see that it's disabled when Aero is off.

Desktop composition controls screen updates (v-sync) but madVR also wants to be in control of screen updates and they conflict so you get stutter or even dropped frames.

With desktop composition off you should avoid most problems but some users have reported tearing (two different frames displayed in the same v-sync). I am not sure why tearing happens with desktop composition off, madVR should v-sync itself, but I have seen it.

It seems like Windows 7's desktop composition was designed while assuming a single monitor at 60 Hz.

Do you know if Windowed Overlay works well with Crimson? I want to remove the note about only for Intel and Nvidia in madVR options explained if it does.

[huhn]

the desktop composition is need for v sync. so with it disabled you don't have v sync so it is need for windowed mode.
the next issue on vista/7 with the desktop composition is that only one desktop composition rate can be used for all devices. so using a laptop with 60 hz only display and a TV is going to ruin your day...
than windows vista/7 have a huge issue with changing the desktop composition. for example you switch to 23p to watch a movie but the desktop composition stays at the old 60 hz for what ever reason.
this happens all the time...

this can be avoided with windows 8+ or FSE/overlay mode.

but i'm pretty sure i was able to break FSE on windows 7 too with my dual display setup. but i'm over windows 7 for a long time.

aero/desktop composition issue where the reason i sticked to crappy XP x64 for some time.

just tested it and no AMD doesn't support overlay.

crimson is just on typical new driver with an new UI that is missing a ton of settings. like deinterlace options and stuff like this.

Win 7 + Madvr = Crossfire always on but stable with no dropped frams

Win 8 + Madvr = Crossfire disabled but you have to use SXBR with no dropped frames (Best Combination)

Win 10 + Madvr = Crossfire always on Unstable, Madvr always crashes (Piece of Crap)



this was running on 2X HD7850 with Latest AMD Crimson Driver (Beta Hotfix.) All are on tested on a clean installed machine.

I suggest you stay away from Windows 10+AMD Crimson Driver combination till they sort this shit out.

Now going back to Windows 8.

Thanks Asmodian and huhn.

I'm using classic theme so no Aero.
Also, I use FSE and I didn't check Disable Desktop Composition (I guess it doesn't matter with FSE and no Aero).
I didn't know about tearing issue, never saw it on my setup (probably because of FSE).

I have Samsung 1080p LED TV, in nvidia control panel I see following screen refresh rates:
23Hz,24Hz, 25Hz Interlaced, 29Hz Interlaced, 30Hz Interlaced, 50Hz, 59Hz, and 60Hz.

What do you suggest to put in Display Modes in madvr settings?

Also, should I enable Smooth motion (I did so far)?

Thanks.

I tested this and indeed it looks like it's bork now . I'm on Windows 7 x64 with R9 200 Series.

[lanzorg]

Madshi could you add supersampling or a way to use image doubling for any videos?

I would use 23 Hz, 50 Hz, and 59 Hz. Set smooth motion to "only if there would be motion judder without it..."

Or nothing and use smooth motion most of the time.

Personally I like using smooth motion and not using display modes, it avoids the flicker when changing display modes. If you notice smooth motion's blurring display mode changing is required but if you don't smooth motion is even better because it perfectly matches timings so you never get dropped or repeated frames during normal playback. When using standard refresh rates you need to use Reclock or similar or you still get drops/repeats. Or you can use custom refresh rates and tune the refresh rate to match the source frame rates almost exactly, this is somewhat complicated and requires trial and error.

Smooth motion is so easy.

How about windowed overlay? Is it functional? Does it work well?

Thanks.

Now going back to Windows 8.

I am still using the non-Crimson driver v15.11.1. Crimson is still too immature for daily usage; then again so is Windows 10. I would have stuck with Windows 7 if it wasn't for DirectX 12.

I am trying to see if disabling ULPS or actually forcing Crossfire to on for MPC/madVR will fix the problem.

As huhn said in the previous page, no it still doesn't work (I think you just missed it )
