i just tried different combinations of scalers.
then remembered that ReconSharp is superior in chroma scaler, so i compared it to NGU low.



i guess ReconSharp is still superior.


also, can we have this part of the image scaler be manually defined like this?
and what would the result be if we mixed up different scaling algorithms in luma/chroma image scaling?

So, 24fps at 24hz, 25fps at 25hz, and 30fps at 30hz?

Yes.Works with everything I've tried,without losing resolution.

are you sure the 25 content isn't interlanced?

i don't know for sure but AFAIK there is no 25p spec only 25i so it is deinterlanced to 50.

@Damien147
don't waste your TV with display mode on this TV
it can't do 23/24p properly like nearly all 2016 smasung UHD screens.

@kitame
you are ignoring the way bigger chroma bleed of recon sharp at the "shoulder".

I'd love it...!

But the issue is that, with just "4096x2160p24, 4096x2160p25, 4096x2160p29, 4096x2160p30" in display modes, 25 goes to 30hz....and not 50...

what bleed? if its the "missing" white outline, thats actually an image sharpening ringing artifact.
if i turn off my image sharpening enhancement the white outline vanishes, in exchange for a blurry edge line.
in fact, ReconSharp seems to "fix" this ringing artifact via masking.
anti-ringing filter simply doesn't work well with image sharpening.

however, ReconSharp does have one issue, there are occasions where theres an odd glitch/artifact.

Go to display adapter properties and check.I am like this http://imgur.com/a/xylW7
I don't have 50 fps material to try 4096x2160p50.Can you suggest me a sample?

Damien, forget 50fps material: it's not the issue, I was just answering to huhn's hypothesis.

What I'm saying is that, if I include 4096x2160p29 and/or 4096x2160p30 in the Display Modes string in MadVR, any simple 25fps material goes to 30hz, instead of remaining at 25hz.
if any reference to 4096x2160p29 or 4096x2160p30 is missing there, 25fps goes at 25hz.

Which doesn't seem a normal behavior, and not corresponding to your experience if I'm not mistaken.

PS: in the display adapter settings I have 24, 25, 29 and 30hz.

Something similar was happening to me yesterday with 24p(it was ignoring it and stayed in 59hz) if I was adding 4096x2160p23 but I can't reproduce it now.

i'm not 100 % sure but i guess madVR uses the highest possible refreshrate if the refreshrate is higher than everything that could be send to the display.

so maybe make a screen of the OSD helps.
@Damien147
the madVR OSD has nothing to do with this.
the TV can't handle the signal correctly. a 24p signal is change to 60 in this TV because it can display at a multiply of 24 like 120 hz.

same for 4096X2160. the TV can't display that. TVs have a resulotion of 3840x2160. you are able to send 4096X2160 and 23/24p that doesn't mean it can handle it correctly or display it correctly it is missing the pixel and the refreshrate multiplier.

@kitame
the red dots...

I don't get why windows displays 24hz+ in adapter properties and 4096x2160 resolution then

Yes, exactly: I'm curious in understanding the logic behind.

Will post a screen as soon as I can.

Thank you!

because that's what the GPU driver is sending the display.

both sides has this issue, actually NGU looks mellower because the entire gold trimmings is tinted red.
the protruding red dots on ReconSharp is due to ReconSharp being... Sharp, if i switch to ReconSoft it looks just like NGU with the entire gold trimmings tinted red.

shes actually wearing a gold trimmed white suit.

It's supposed that windows shows what's only supported for the display.

last commend about this.

the resolution of this and nearly any other UHD TV is 3840X2160.

because you can send something doesn't mean it can be displayed correctly and yes the TV supports this type of signal as an input and again it can't handle it correctly.

using 60 HZ and madVR smoothmotion is the better alternative in term of correct playback.

if you send 4096X2160 it is cropping the side of scaling the image down or changing the AR.

if you send 23/24p it has to create a 3/2 judder by displaying it at 60 HZ. this screens doesn't support an internal refreshrate of 48 96 72 120 or what ever that allows correct 24p playback. which means it can't display it correctly.

I have the same/close to same tv ku6290 and windows even recommend 4096 by default, but that doesnt mean it is the best setting. ( I was wondering why am I getting crop image at first)

The electronic hardware(which communicate what signal it can take) in the TV have nothing to do with the capabilities of the panel it seems.

I was with smooth motion and in 60hz.No cropping here and sorry but what is ''changing the AR''(?)
I just played with MadVR display modes and got these results.
Facts state that everything is working but somehow as you say it's not correct.

You got cropped image because by default fit to screen was off.I had the same thing happening to me.
In your TV go to: settings-->picture-->picture size and put screen fit to on.Now return to 4096x2160 and see for yourself.There is no cropping.

You don't get it with your screenshots.
The problem is not what you send, but what the TV does AFTER you send signal. That's what huhn is trying to say.

From rtings review, 24Hz is not judder-free for your TV. But maybe its motion interpolation is able to give a good result.
