ProjectorCentral - Sony VPL-VW285ES 4K SXRD Projector review: Quote:
Edit: For limited range video I prefer to use YCbCr 444 over RGB, limited is a normal concept for YCbCr while it is weird for RGB. Limited RGB uses 16-235 for all three planes while YCbCr uses 16-235 for Y but 16-240 for Cb and Cr. You would need to set madVR to full range when setting the GPU to YCbCr 444. 10 bit YCbCr 444 limited at 30 Hz or less should be a great option for that projector. Quote:
Hard to argue with that but something seems off to me. Quote:

MadVR shows that the 4k HDR Remux videos I play are "P010, 10bit, 4:2:0 (DXVA11)" in the statistics. That is where I am getting the 4:2:0 from. My actual settings are: Nvidia is RGB Full 12bit @ 23.976, MadVR output set to Limited, PJ set to Limited. I think it is just ME saying things wrong that is leading to the confusion! "Your projector has very good coverage of BT.709 but it is less good for wide gamut, most colors will be more accurate using the BT.709 mode on the projector." I noticed this as well. Both on reviews and in person. When switching to HDR content, colors are crap. But in SDR they are vivid and rich. So with madvr tone mapping to SDR, and outputting at 10bit, I think I am getting the best I can with the setup I have. PS - Asmodian, wanna come over and give an in person review? It's only a 3000 mile drive and a 2 week quarantine! hahaha |

That line is telling you about the source, madVR received 10 bit 4:2:0 video in the P010 format from DXVA11 hardware decoding.

My guess @ what's actually happening to lordX2 is that the projector goes into a pc mode of sorts when fed 444 rgb full, on many systems this disables the dynamic brightness/contrast image manipulation of the projector itself. and it may well clamp to rec709 instead of native p3 gamut. This could account for the loss in perceived saturation both from the contrast and gamut difference. Potentially also following a different gamma curve
For an image to be rendered too brightly due to levels mismatch, The PC has to send the wrong 16-235 levels while the Projector is expecting 0-255. If that is NOT the case, then the projector is doing full rgb correctly. This is why you need to check the 0,0,0 black, if that black is about the same, while comparing both modes with all dynamic contrast/iris settings disabled, THAT MEANS the projector is doing the RGB Full correctly.

@ Asmodian.
If Madvr is doing math to go from rec2020 to P3, then isn't it always better to feed it a rec2020 lut ? Because that way, Madvr can do 1 less mathing of the gamut, we rely on argyll cms to math the gamut ONCE, And this side is more reliable because they are compressing using actual measurement data, WHEREAS, if Madvr does their math even once, it's Blind math, made with assumptions that don't always hold up on real color systems.

Well, not in practice, but theoretically you do want a custom 3DLUT for every source color space.
The difference between BT.2020 and DCI-P3 is a purely theoretical and an absolutely precise mathematical relationship, both sides are their theoretical color spaces. Assuming you are working with DCI-P3 encoded in BT.2020, the normal case. I haven't seen anything mastered in BT.2020 since there are no displays capable of displaying it. When mapping to a real display we need to make tradeoffs, and making tradeoffs twice is bad, but when mapping DCI-P3 range in BT.2020 to DCI-P3 you do not need to make any tradeoffs. When I used software 3DLUTs I did make all the SDR LUTs, since that is so quick, but the difference was not measurable with an i1d3. I use passthrough for HDR so I haven't messed with HDR 3DLUTs. That said I would want a BT.709 and a DCI-P3 3DLUT, assuming my display's native gamut was very close to DCI-P3, and not worry about the pure math BT.2020 -> DCI-P3 conversion.

not sure if madVR does that or if it is worth any processing power but if you are tone mapping you can can do that to the gamut conversation too. so the tone mapping could do a better job if it knows that the gamut needs to be compressed too.

Absent real offsets it's still very possible to swing wide even if by definition it should hit. The data may be perfect but when you cast it, /problem. I believe that movie Shadow is rec2020, but the bulk of the movie is greyscale, so idk what they were going for.

I meant minus 55% performance with the option unchecked, so it does indeed saves performance. Or, if you prefer to phrase it another way, more than 2x the rendering time if the save performance option is not checked.

I am planning on installing win 10 v1909(currently using LTSC 2019 on ryzen 1200 with 1050Ti) but heard that too many updates result in issues with madvr. Would you recommend it over LTSC & if yes then are there any steps to follow to avoid issues with madvr?

I am using Win10 20H2. No issues with madVR after lowering the frame presented in advance.
What issues are people having?

Most of the time the problems are with GPU drivers or the OS itself and get resolved after a few weeks. IIRC I've only seen one issue with Windows 10 where a change was needed in madVR itself, and it was resolved by madshi after some months. Quote:
Of course the case with an even bigger performance gain is where display def = exact half of video def.

Currently there seems to be no issues but I have noticed some serious fluctuations in download speeds of my wifi(maybe my case only as I am using an old usb ac wifi adapter which works fine on win 8.1 in another system) & also Microsoft had released update for ryzen scheduling issue in v1903(LTSC is v1809) which can increase the performance of ryzen processors by a decent amount in gaming like scenarios so thinking of trying the v1909(comments suggests it is very stable plus enterprise version support is there till 11 may 2021).

If you're going to switch to the standard branch and you've got recent (= still supported by manufacturer) hardware, I'd switch directly to 20H2. It's the same kernel as 20H1 so it's been out for 6 months now, all the showstopping bugs have been fixed and you'll get 12 additional months of updates compared to 1909.
If you're worried about issues, just update Windows once a year around november/december and you should be fine.Both really. I update to a newer Windows version once a year around november/december, and for monthly updates I manually pause them and update during the second weekend after patch tuesday (i.e. a week and a half after the monthly update is released).
