And what are you EXPECTING the readouts to say? as in, what is your intended outcome.

You mentioned this already, prompting a question from me IIRC.
At present time your statement is just wishful thinking. I would accept bets that all this year independent shootouts will be won by an OLED TV.
Now, considering that discussion of competing TV technologies is kinda off topic here, would you please refrain from similar comments in the future? They're pretty much useless.
Thank you.

Yes GTX 650 Ti and DL580G5.

I wish I could use in MadVR DXVA resizing for chroma upscaling ... just to be able to play my movies in native resolution (ie to be able to watch a 1440p movie on a 1440p screen or a movie 2160p on a 2160p screen)

DXVA resizing for chroma upscaling, it works if LAV is in DXVA/DXVA Copy-Back mode but not in software mode ...

Its a Mid-2019 screen without HDMI 2.1, so better to pass anyway.
Maybe next year we'll finally get complete screens without tech shortcomings like that.

Fair enough. Not like I'm buying a new screen any time soon. I'm quite happy with the C8. I just wish Panny hadn't abandoned the US. I understand why they did but it sucks for us.

I had been playing a bit with the thought of replacing my TV but after I learned more about current HDR implementation I decided not to. I'll use this TV until it lasts and I spend my money on anything else!
I saw your posts about it on AVS I used to be very active in that thread. My mainboard broke shortly after I had replaced the 550 and given it to in-laws. Those models were notorious for doing that. At the time, I would not have thought I'd buy another LG anytime soon, but here I am with my OLED Great to hear that yours still works. Was a good TV at the time, unlike anything non-OLED from LG right now

U playn' movies off dl580 ? hahahaha.

I got 2 of these quad cpu servers and 128gb memory each at home. The quad redundant power supplies, 600watt idle on each machine.

Kind of a waste of electricity if u only turn um on to watch mewviez. Also pretty loud..


What is exact resolution of the monitor ? 3440 x ??

They willll make display port 1.4 to hdmi 2.1 adapters right ?

RIGHT ???????

Hi all.
Interesting, why NGU AA does not work in quadrupling (4x) mode like NGU Soft/Standard/Sharp for image upscaling? Оr am I setting something up wrong?

@vanden Workaround for you: in the settings of LAV Video, uncheck all the 4:2:0 and 4:2:2 output formats. This will force LAV to do the chroma upscaling itself in software. It will also convert to RGB, it won't output 4:4:4 YCC.
Of course this will probably be lower quality than madVR's own processing, but your GPU is in way over its head with madVR's HDR tonemapping.
Also for HDR10 with that setup, LAV will still output RGB32 unless you uncheck it and force RGB48 but I don't know which of those is the best for madVR.

Unfortunately I'm not sure it's even possible to use DXVA only for chroma upscaling if you're not also using it for decoding, deinterlacing, or image scaling (maybe madshi can give more information on this).

They saw no real need for it. They said you can add the 2.1 featureset to 2.0b anyway.
Just a shame we still haven't got 120hz display refresh.

I see a need for it, specifically when running a HTPC, because the bandwidth of HDMI 2.0 is just too low - and thats not something you can add without a HDMI 2.1 transceiver.

I want to be able to run at 4K 10/12-bit no matter the refresh rate, which is not something I can do with HDMI 2.0, because 60Hz exceeds the available bandwidth.

Also, eARC, with streaming services also introducing better audio, and many clients for such services being baked into the TV itself.

Yeah same, although we are in the minority of their customers.
LG got you sorted this year.

Indeed, and I applaud them for commiting to it.
Although I'll probably only start seriously considering a new TV next year. Finally the tech has caught up, both with HDMI 2.1 and HDR performance, and next year we'll hopefully also see widespread DV and HDR10+ support like that Panasonic has.

Would love to see a shootout of madshi's HDR box vs any other TV's Dynamic Tone Mapping, madshi may I suggest providing Vincent Teoh from HDTVTest a review sample once it's available?

It wouldn't really be a fair comparison because the TV can control its internal PQ scaling and madVR can't. It can only send rescaled PQ values to the display and it is up to the display as to what it does with these values. There would be have to be some sort of mode in the display and some controls to guarantee that the output is displayed 1:1 and not displayed at a different luminance or with any other unwanted color space conversions.

It would make more sense to compare directly with an external processor such as the Lumagen Radiance Pro. Seems like a guarantee that Kris Deering of Sound & Vision/AVS Forum will make this comparison because he is always reading the madVR thread while simultaneously selling Radiance Pro's.

FYI, Soulnight at AVS Forum started a thread about the Envy. I just saw it today and found some interesting tidbits about people's expectations for this thing:

madVR ENVY: Anticipation thread!

One limitation not mentioned versus a HTPC is that madVR doesn't have access to the decoded frames. If you used a Nvidia Shield as the source, for example, you would still have to live with the Shield's flawed video output. Devices like the Shield do let you choose different output resolutions for different content, and there are obvious advantages such as accessing a few 4K HDR movies that will never be ported to UHD Blu-ray or 4K HDR Netflix and Amazon TV content.

@ el Filou
Thank you, this is a track until madshi statu on this problem.


For all the tests following LAV is in SOFTWARE Decoding Mode, File 1440p 10bit HDR (MPCHC x64).

If I uncheck P010 in LAV : LAV makes the converssion 10bit->16bit and in madVR I enter in 16 bit 420 (P016) and madVR makes a chroma upscaling in DXVA Mode !!!
I guess the HDR ton mapping is done in 16bit in this case ? but it does not have to be really embarrassing.
it works well GPU stable @ 58% CPU @ 15% :


If I uncheck P010 and P016 in LAV : LAV makes the convention 10bit->8bit in madVR I enter in 8bit 420 (NV12) and madVR makes a chroma upscaling in DXVA Mode !!!
I guess the HDR ton mapping is done in 8bit in this case ? Not ideal if that's the case.
it works well GPU stable @ 55% CPU @ 12% :


If I uncheck all 420 (NV12, YV12, P010 and P016) and 422 (YuY2, UyUV, P210, v210 and P216) in LAV : In madVR I enter in RGB32 (LAV does chroma upscaling with I do not know what algorithm + convention YUV to RGB).
I guess the HDR ton mapping is done in 8bit in this case ? Not ideal if that's the case.
it does not work well, some presentation glitches GPU @ 79% CPU @ 19% :


If I have everything checked in LAV : in madVR I enter in 10bit 420 (P010) and madVR does a chroma upscaling using TextureUnits/PixelShader (Bilinear, Cubic ...) and it does not work GPU @ 92% CPU @ 17% :


If I have everything checked in LAV and screen set @ 2944x1656 : in madVR I enter in 10bit 420 (P010) and madVR makes a chroma+Luma upscaling (2560x1440->2944x1656) in DXVA Mode.
it works well GPU stable @ 71% CPU @ 16%
https://i.goopics.net/wEv2y.jpg


So madVR can use DXVA for chroma upscaling in 8bit (NV12 and RGB32) and in 16bit (P016) but not in 10bit (P010) ! it's very weird anyway !



@ tp4tissue
Yes it is greedy in electricity ...
For noise I modify the system that manages the speed of the fans ... it's really much less noisy.
For the screen it's a LaCie electronblue IV 22" CRT screen.
Support :
2880x2160 @49-50Hz (4/3)
3104x1746 @49-50Hz (16/9)
2944x1656 @49-60Hz (16/9)
2560x1600 @49-60Hz (16/10)
2560x1440 @49-72Hz (16/9)
2240x1680 @49-75Hz (4/3)
1920x1080 @49-120Hz (16/9)
1600x900 @49-144Hz (16/9)
Etc …


Edit :
For all tests following LAV is in SOFTWARE Decode Mode, File 3840x1606 10bit HDR (MPCHC x86 + Reclock). Screen in 3104x1756 and in MPCHC : Video Frame/Normal Size.

All the tests by modifying LAV does not work (NV12, P016, RGB32), example in NV12 :
https://imagizer.imageshack.com/img921/8541/1MFFhC.jpg

On the other hand If everything is ticked in LAV (P010) and I put -2% on the zoom in MPCHC (the image is resized in 3766x1576 / via DXVA chroma+Luma upscaling) it goes :
https://imagizer.imageshack.com/img922/2303/Fw3uXy.jpg


I guess in P010 and just DXVA choma upscaling it would be perfect ...
