Can someone please recommend settings for:
  • Chroma upscaling
  • Image upscaling
  • Dithering
When scaling a 720p video to a 1080p screen with a GT740 GDDR5 card.

Try, NGU AA low, NGU Sharp medium and Ordered Dithering.

Any other recommendations, of which I should take note?

Can someone recommend settings for :

-Chroma upscaling
-Image upscaling
-Dithering

and other settings when upscaling 720p\1080p to a 4K screen ( LG OLED 55C8 which I heard has quite poor upscaling quality . I will have it on Monday and would like to be prepared )

PC :

CPU: I7-7700K OC 5.1GHz ; GPU: Gigabyte GeForceŽ GTX 1080 WINDFORCE OC 8GB ; MB: Asus ROG STRIX Z270H ; Cooling: Arctic Liquid Freezer 240 ; Memory: Corsair Vengeance RGB (2X8GB) DDR4 3100MHz, ;SSD: Corsair MP500 240GB NVMe (PCIe)+Samsung Evo 850 Pro 256GB ; Case: NZXT H440

It is really a matter of preference. Delay playback until the render queue is full and D3D11 for presentation are the only obvious settings. You would have to try the others.

It is really better if you just start with the default settings and adjust things until they look good to you. Many would recommend NGU AA or Reconstruction soft for chroma upscaling, and NGU Sharp or NGU AA for image doubling.

I would avoid Error Diffusion dithering for your 4K profile, especially if you are outputting at 10-bits. This eats up a lot of processing for very little.

Asmodian, madshi,
is this true also when the "passthrough HDR content to the display" and "send HDR metadata to the display" are enabled? I don't think it would make any sense to do so having in mind that by default the TVs (and may be also projectors) will switch display modes when it receives the HDR metadata and this means (usually) totally different configuration/calibration including support for the wider color space.
I'm a bit lost on this topic but I have the feeling that we need two separate sections (one for SDR and one for HDR) for telling madVR how our displays are calibrated ... or am I missing the whole point here?
I apologize for asking this question again but I simply can't believe that madVR will behave so user unfriendly to downconvert everything to BT.709 and pure power 2.2/2.4 including real HDR content.
btw
what will madVR output in these cases (BT.709 SDR source and BT.2020 HDR source) if I select "disable calibration controls for this display"?

hdr pass through is not effect by this only sdr output.

i mean common how can you pass through meta data and convert it to gamma at the same time?

OK,
now that you say it like this I kind of see the stupidity of my question.


but just to be sure - the same applies to the other two options that output HDR (process HDR content by using ....), right?
And the calibration settings are actually in effect only when there is native SDR content or a conversion from HDR to SDR using either pixel shader math or external 3DLUT, correct?
If that's the case may be the calibration tab should be renamed to "calibration for SDR content"

you can read it in there pixelshader is by default converting it to DCI-P3. i guess it is still sending bt 2020 or at least DCI P§ and says it the screen.

and using a 3d lut is well doing color correction by using a 3d lut.

I'd like it a bit sharper?

it's chroma we are talking about it has little effect.
you can try super xbr.

you can try adaptive sharpening what ever you like but don't expect it much from a 740.

I turned on Sharpen Complex 2 in MPC-HC.

Any special recommendations for Chroma, Image and Dithering for a 1080p video on a 1080p screen, when used in combination with MPC-HC's Sharpen Complex 2?

You could try the image enhancements in madVR instead. You could also increase the strength of chroma upscaling to medium or high, if possible, but this will only have a small impact.

The rest wouldn't change.

I changed NGU to Soft and combine it with Sharpen Complex 2. It doesn't look way too sharp or not sharp enough.

If there are any reasons not to use NGU Soft, do tell!

Did you compare it to NGU AA? I usually prefer NGU AA over Soft but if you like soft more there is no reason not to use it.
