MadVR HTPC build for JVC NX7 projector - a build!

I recently purchased a JVC NX7 projector, a fabulous piece of equipment, that displays a really good image.

But like all things there is room for improvement, mostly on HDR tone mapping.

Therefore I have decided to build a HTPC with MadVR to handle the 1:1 blu-ray rips. I currently use Nvidia Shield to play these using Kodi.

An added benefit would be that I will be able to use Netflix Windows 10 app, and get Atmos support (something the Shield lacks)

So without much adieu, here is my partlist:

https://pcpartpicker.com/list/jfgMNQ

I will also add FLIRC Universal Remote Control Receiver to easily control the PC with my Logitech Harmony remote.
https://www.amazon.com/dp/B01NBRBWS6..._JrvDCbQXTP9Q1


Also I have Mobile Mouse Pro app on my phone, that will be used to provide basic keyboard and mouse functions.

I plan to use Windows 10 as the operating system - I will use the free version from MSFT website - unless they require activation at some point in future - wherein I will reuse a spare licence I already have.

Finally, you will notice in the part-list that there is no large capacity hard drive. My movies are stored on my Synology NAS, as well as on a 8 TB USB3 HDD I bought from Costco a few months back.


To be continued ...

MadVR HTPC build for JVC NX7 projector - a build!

JVC Settings

Five things that are quite important.

#1 Turn on Low Latency. Turn off Motion Enhance. Turning on Motion Enhance can cause artifacts in a lot of movies (e.g., in the night scene where the truck us stuck in Sand in Mad Max Fury Road). Note currently as of May 3, 2019, while using DI with HDR color profile causes yellowing. Using BT2020 does not have yellow DI - at the cost of ~10% light output. Personally, I am using BT2020 profile, and just have MadVR tonemap to a lower target nit.

#2 If you have a large screen (120 inch and above), use the HDR color profile vs BT.2020 - you will need the extra light output to really let HDR shine

#3 Keep the contrast setting at 0, Brightness as -2 or -3 to get the best contrasts.

#4 Personally I find using gamme 2.2 better than gamma 2.4

#5 Input range: Set to 16-235. (setting it to Auto, or full causes the image to wash out - you get more detail in the dark areas, but the contrast really suffers)


Windows 10 settings:



Resolution: 3840 x 2160, 23p. I use 24Hz as this minimizes the sync when a movie starts since most movies are in 24 fps



Windows HD color: Turned off in Windows. We will let MadVR use Nvidia APIs



Optimize content: For video





Nvidia GPU setting:







Resolution: 3840 x 2160, 23p. I use 24Hz as this minimizes the sync when a movie starts since most movies are in 24 fps



Bit depth: RGB, 8bit, Full color (On my card using HDMI, I can only select 8bit. Which should not be a problem -- atleast from what I have read)


Nvidia RTX Card’s suffer from stutter. Refer to the following threads for recommended drivers if you experience stutter.

MadVR settings for JVC NX7

MadVR settings on Madshi's #78 test build:


Link to the build http://madshi.net/madVRhdrMeasure78.zip

These settings are dependent on the setup you have. So I would like community help in building out a scenario specific list. Anyone who has tried MadVR with a JVC PJ please chime your settings and I will add them here


[I]Setup: JVC NX7
Screen: XYscreens 4K Soundmax (~1.0 gain), 130" gain.
Nits: Real peak nits ~ 70
Lamp and Iris:Low lamp with Auto iris, Manual iris set to 0
[/]

I found that in the test build setting Target Nits (green colored text) has no impact. Changing Maximal target nits and dynamic tuning are the real drivers. Other settings are parameter to improve scene detection - which I am not very familiar with so I defaulted them to @Neo-XP settings

For "consumers" changing the two settings above should do the trick.

Changing the Maximal target nits lower brightens the image. I found that setting it close to the actual nits I get gets me the best picture.

Changing the Dynamic tuning subtly alters the image. For my setup 100 shows the best results.




My basic MadVR settings (still WIP) are in this folder. People interested in setting only HDR tonemapping refer to the screen shot labeled MadVR tonemapping

How is the noise on the Zotac? There was a link posted (I think on the main building a 4k HTPC for MadVR thread) to a German review site that compared a bunch of 2060 boards and found the Asus and MSI significantly quieter under load than the eVGA.

I dont have the card on me yet ... will be a few days before Newegg gets it to me.

I went by this reviewers recommendation to buy Zotac over MSI based on the pitch of the sound (lower freq vs. higher freq). Sounds compare at ~11 mins

I'd pick up a logitec k400 keyboard / trackpad combo. They're great for this type of thing.

I have been eyeballing the Zotac card a bit myself, seems like one of the only decent dual fan models at MSRP. But their resale value is one of the worst, and also the warranty is two years instead of the standard three from most GPU makers.

Stock cooler. I think MadVR is not CPU heavy so don’t think I need anything more.

At 19 bucks the power supply was too much to pass . If it indeed is very loud I will get something else. Newegg gives me 30 days...

The stock cooler is loud also. That is why i asked. You are right that the stock cooler is fine for keeping the cpu cool.

Thanks for starting this thread. I'll be following your progress... and doing my own build at the same time. My build is a bit downscale from yours (JVC RS400, PC built from salvaged parts plus a new Radeon 580), so it'll be a good contrast.

Question for you... are you confident that madvr can tonemap netflix HDR from the windows app? I've searched around for people doing that and haven't found confirmation that it can work.

It absolutely cannot. madVR works only with the media players listed on the website.

OK, thanks. It's great to get resolution on that, but definitely disappointing. Do you think it'll happen at some point?

I very highly doubt there would ever be a way to feed a DRM-filled stream into a third party video renderer such as madVR.

However, having enough room for the video card seems to be a sticking point. Asking opinions, if wanting to use this kind of case is unwise? Also, since I have no background in the PC game, I use Macs, would anyone like to put together a basic parts list that would include gear that was quiet, compatible and good enough for the task? My budget is 1k of below.
Thanks
One of the best HTPC cases is the Silverstone GD09 or GD08, both of which have room for even the largest video cards.

The build listed above is more than enough for madvr. If you want it to be quieter, you can use a BeQuiet power supply and Noctua case fans instead of stock, plus a Noctua CPU cooler

Man dump that $114 window 10 pro purchase. You can get licenses for $10-30 on ebay and you can download windows 10 pro off microsoft's website. Further, if you never activate windows 10 pro, it works forever but you get no windows updates. For an HTPC this might be good as you never have to deal with pulling out a keyboard to handle it or click away nags. The watermark about activation can be disabled with a simple registry key entry.

Well you never need to "register" windows but if you can't activate it, you should get a refund. But if the HTPC isn't going to be used to go online and do other things, I prefer to just disable windows update. I mean you want the pc to just work with a remote not to have to keep pulling a keyboard out to click away constant update nags. I would disable updates for video card drivers, not install geforce experience, not enable any updates for anything. I guess if you're going online with it that's different. The best way to disable windows updates is to not activate windows and disable the watermark with a register key you can easily google. All this is legal as you'd be getting the software directly from microsoft and using just their tools to do it.

You do know that you are likely promoting piracy right? Those are stolen keys. To each their own on how they obtain their windows installations on their own time but there is no "cheaper" way to get windows other than from microsoft, full retail boxes, oem, or through corporate/student licenses. Everything else is just skimmed keys from msdn etc resold on the internet. None of those sellers or "companies" are legit or legal. I wouldn't recommend telling others to do it that way.

On the flip side.. there was a way to use windows 10 as a demo early on using client setup keys which was perfectly legal. I'm not sure how long you could do it for, or how long it would last, or if it can still be done. I never looked into if this could work with an HTPC either. Might be worth investigating. *shrug* If you have an old windows 7 key you might still be able to use it to upgrade to windows 10 for free too. (At least you still could as of last year)

Got my HTPC up and running. Tried JRiver as the front-end but it won't use HW acceleration with high-quality settings and my Radeon. So I switched to MPC-MC for now... figured that'd be simpler to get started than Kodi DSPlayer.

I used madvr default settings plus the recommendations here: https://www.avsforum.com/forum/24-di...l#post57654684
and checked 'measure each pixel'.

Also, I updated the calibration tab: I checked 'this display is already calibrated', BT2020, pure power curve, Gamma 2.4 (projector is using my SDR2020 mode, setup by ChadB)

Anything else I should be doing? It looks pretty good... but not sure it looks any better than just using Kodi out of the box. Source is some ripped HDR blu-ray movies.

Is there some well-known test scene I can use to do an A/B comparison? I've got Lucy & 5th Element ripped... I know those are fairly-commonly used discs for comparison.

And if anyone figures out exactly the right settings for an NX7 + Paladin DCR lens + madvr so that you can keep the lens in place all the time and have madVR do all the scaling, let me know! I've been reading numerous sites on this all day trying to figure this out

MadVR HTPC build for JVC NX7 projector - a build!

Finally put together the PC ... Just waiting for the RtX2060 to be delivered Newegg shipping could not be slower. Taking a full 10 days to deliver!

But have run into problems installing Windows 10. Will have to troubleshoot tonight ...

There's no piracy being promoted here. The keys you buy on ebay come with CoA stickers. These are issued to system builders by microsoft and microsoft was paid for the CoA. There's no media provided you download straight from microsoft's website so there's nothing coming from MSDN etc.

Might be worth investigating. *shrug* If you have an old windows 7 key you might still be able to use it to upgrade to windows 10 for free too. (At least you still could as of last year)
You dont need any tricks. You can simply download windows 10 from microsoft's website and install it. Then never activate it, and it never expires. You have a watermark on the bottom right of the desktop, but you can disable that with a registry key.

Question for you... are you confident that madvr can tonemap netflix HDR from the windows app? I've searched around for people doing that and haven't found confirmation that it can work.
MadVr creator Madshi is releasing a MadVr Envy box that can tone map any source, no release date yet but he said soon, so that will definitely do netflix tone mapping.

I apologize for the blatant blame without an addendum! If you get a physical CoA sticker (And not a photo of one) then that is awesome! I was referring more to places like your typical online key sellers like Kinguin, who re-sell the same keys over and over again, etc.

Got my HTPC running on my current desktop with a GTX1080. I may build another computer, but for now I will just run a long HDMI cable to my receiver. One thing I realized though during testing was that the HDMI cable I was using was an older cable so it couldn't reliably run 4K HDR. But during configuration I got to the HDR tone mapping portion and realized I was just sending SDR anyway so that actually cleared up my cable issues. I'm replacing it with another longer cable anyway that will run HDR just in case I need it in the future. Ordered my RS1000 from Mike this weekend so I'm just waiting for delivery now, very excited!

Updated my madvr to the latest test build and now I *do* see a small difference. The tone mapping adds a bit of detail in highlights that are blown out when watching in HDR mode.

But question is... is madvr one of those tools that provides a tiny improvement or a huge one? I realize that's subjective, and maybe my projector (RS400) isn't high-end enough to really benefit from the tone mapping over my custom curve. But I read so many raves about madvr, that I'm surprised my jaw didn't drop when I saw the results.

It takes a really long time to get just the right settings. But the best way to see a huge difference almost immediately is to use Soulnight's measurement optimizer tool with mostly default settings on a UHD file

Edit: also, while the tone mapping is really really good when you have the right settings, what really blows people away is the upscaling
