The reading was in F.C. result 17.5 average over the scope screen with Isco IIIL lens in place.
I then converted FC to FL by multiplying by the screen gain 17.5 FL x 1.2 gain = 21 FL

Then converted FL to nits 1FL = 3.4263 nits
Result 21FL = 71.95 nits

Have I dont this correctly. so I use say 71nits for my target in madvr tone mapping?

I dont need to use the size of the screen in the calculations???

Well after you load your 3D lut, just go by eye, because a number doesn't really help here, it's a To-Taste situation.

Freeze frame at scenes with HDR highlights, and tune it up or down until YOU like it.

Then try a few other scenes.


NX9 looks expensive. are you planning to buy a spectro to go with it ?

Strange, then I don't know why HDR variable doesn't work for you with that setting.

I'm happy with it but I was wondering if its would be wise to get a refund and replace with a rtx 2060? That's what I was wondering.. And if so.. Is there a specific 2060 model that is recommended? Asus Strix comes to mind but I may be wrong.. Thanks
Maybe Madshi goes AMD in the future because Vega 7 has some sort of advantage given its HBM ram. Or some other feature set.

We can't buy a graphics card , "betting" that madshi will implement some use for it in the future.. Because no one knows if that will happen, not even madshi..

If you need a card, at this very moment, 1070/1080 gtx seems to be the performance lvl necessary for NGU chroma + HDR tonemapping

If you're not NGU obsessed 1050ti and 1060 will be fine.

I saw used 1050ti from evga for ~$90

used 1060 is tough, because there are lots of bad models, but good models usually go for $170-180. it got more expensive recently after the amd announcement of no competition for that bracket.

Light Modulated IPS is the future.. OLED is obsolete.

I agree with you in this, especially with these insane GPU prices. It's not just about the money for me but principles.
And that's the good thing about HTPC that you don't have to be future proof but only buy a new (used) card when it's absolutely needed.

Then I hope my current TV will last another 10 years!

So you keep saying, but a Google search mostly brings up talk of Panasonic in 2016.

Alas no one can see your screenshots as you can see, they are awaiting moderation. Upload them to an image site and share the links.

But I think you are trying to do too much with the information you have given.

Sounds about right, provided the screen gain is actual and not advertised. My advertised screen gain is 1.3 (Carada BW), actual is just above 1. I think you only need screen size to calculate lumens.

So yes, 71nits for the target in HDR pixel shader is what you can use, but there are other settings that have a strong impact on the picture brightness.

Eh, can't watch content on future TV sets yet. OLED ain't going down the stack any time soon.. Look at that 1000 nit peak GZ2000 beast and drool.

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 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 ??
