Too much demands energy.

Folks,
regarding upscaling 2k to 4k, please check this review of Sony VW1000ES 4k projector. In the middle of the page, reviewer David Mackenzie shows 2k to 4k upscaling results and compares 3 situations: Upscaling OFF, Sony Reality Creation ON and Oppo BDP-103 upscaling ON.
http://www.hdtvtest.co.uk/news/sony-...ture%20Quality

The ultimate question is: Can madVR using JINC (3/4/8) beat these techniques in terms of upscaling artifacts and clarity? ( supposing we have sufficient hardware in the HTPC ).
Thanks

[AndreaMG]

I'm also curious about the comparison regarding SD to 4K scaling, the pixel gap is sooo huge that it should be easy to tell the difference between a good and a less good scaler. That said, in Jinc I trust

I would expect Jinc 3 AR to look as good or better than DRC, especially with actual video content. That's not to say it's perfect - there is still room for improvement.

The problem is that those are photographs, and LCoS is rather soft, which helps smooth things out, so you can't really compare those images with screenshots. I would definitely be interested in seeing a comparison on a 4K native display though.

I did try creating a similar pattern though, and this is the result with Jinc 3 AR:


What I also noticed when doing this though, is that if the source image is not a multiple of 8, madVR does not seem to resize it correctly.

Hi guys,
I'm David Mackenzie.

Sorry I didn't get a chance to test madVR. But, here's the original pattern I made:

ati ore nv?
7850-7970 ore 660-680

For 10 bit, I believe you need a pro. card. Maybe a Quadro?

do you have any suggestions which setting better to disable or enable in CCC, starting from default values?

Thanks David. The results look pretty good with Jinc 3 AR here, but obviously I can't see how that compares to the other processing without access to one of those projectors.
Jinc can look a little soft with very fine details, but is preferable to aliasing or sharpening artifacts in my opinion.

Sony's DRC maybe avoids ringing a little better (hard to tell from photos) but Jinc seems to look a lot more natural with real picture content.

Do you have a sample of this type of content?

madVR does not currently support greater than 8-bit output, so there's no point in buying a pro card for it. (at least not yet)

David, next time you review a 4k tv/projector do not forget to test MadVR jinc upscaling and report back pronto

For some reason when setting FFDshow OR VobSub subtitles to delay + or -, it doesn't work for me using ZoomPlayer with madVR and LAV decoder. Is this a known issue or any suggestions as to what might be going wrong

ZoomPlayer + MadVR + LAV + FFDshow Subtitles

That looks exactly like what I ask for in the review: clean edge adaptive scaling without the other 'detail enhancement' tricks.

So, I'm going to buy a new GTX 670 but before I do I just want to make sure that it's worth it compared to getting a half price GTX 660 if all I'm going to use it for is playing bluray material. Possibly 2 blurays at the same time on a 2560 x 1440 resolution with the highest image upscaling algorithms. I don't plan to game with it at all.

The major difference I see between the 660 and 670 is that the 660 has a 192-bit vs 670's 256-bit Memory Interface Width.

Thanks. FWIW, I've tried to match the photographs in your article by resizing a bit more (with Jinc3 AR), upping saturation by a monstrous 1.4 factor, then doing some rotation in photoshop. Here's the result without any added sharpening:



Of course the Sony projection photos are at a big disadvantage because all the limitions of the projector and digicam add up in making those photos look worse. Also my screenshot has an advantage because I had to upscale more than 2x to make the image size match your photos, so my screenshot simulates a projector with a higher than 4K resolution. I do wonder though why those claws look so much thinner (which is probably more true to life) in my screenshots compared to those projection photos. That's kinda weird...

madVR in its current state uses only a very minimal amount of memory bandwidth, so that should be the least of your concerns.

The GTX 660 Ti should be the clear price/performance winner for madVR between the GTX 660 (~$220), GTX 660 Ti (~$290), and GTX 670 (~$360), especially if you decide to overclock.

[dansrfe]

cyberbeing,

From within this link which would be the best buy in your opinion? Thanks!

[cyberbeing]

If quietness is important, you should probably only look at the dual-fan non-reference models. I think nevcairiel and a couple others here own the ASUS DirectCU II model, and they have been satisfied with the noise level. As luck would have it, that model seems to be on sale at the moment as the cheapest non-reference option from NewEgg, even without the rebate.

[ryrynz]

A fine recommendation there from Cyberbeing, you really can't go wrong with that card.

[jmone]

I (and I think nevcairiel) have the ASUS DIrectCU II 660 (not the 660Ti). The noise level is OK not great in my Shuttle.... eg when pushed there is fan noise at the seating distance when the Audio is muted when working hard (eg 1080/60i material on Jinc3 AR).

[dansrfe]

Wow, the card looks great cyberbeing. Just ordered it along with the rest of the stuff for my new build! Thanks!
