Hi, please can someone check something for me, I dont know if this is something ive somehow missed before or i have a problem. Avengers infinity war, i'm seeing ghosted black vertical bars quite thick sometimes right from the start of the movie, they appear to me more pronounced when there is more popping out of the screen, is this normal,have I just missed this?

checked a few other 3D movies I have, nothing but I checked regnorock, that has then as well, sometimes thick sometimes very thin, sometimes not there at all.

Its like the movie isnt centered properly or something, i've check there is no zoom and my aspect ratio is correct, does this with all my players so not software issue I dont think.

If you want to reproduce content with high fidelity you should calibrate your display, not use fake "auto white balance" processing.
this make sense, i always thinking why madvr did not have auto wb, now i understood that it best to let this job to the display in the first place to make true White balance
thanks @el Filou to explained this.

he was very clear that he recommends 8.1 over 10 the last time he did it in this thread is about a month ago.

OK

I'll try it.
Just starting to install in a new SSD.

But...the newest build of MadVr works just fine under Windows 10 too.

A small query,does system ram mode(single/dual) & frequency matters for madvr. I have a ryzen 1200+B350mobo(yet to open) & used 1050Ti but no ddr4 ram.I am planning on getting a single stick 4gb 2400mhz ram for now. This system is mainly used for watching 720p/1080p videos connected to a 1080p TV.

the ram speed shouldn't be important for madVR but 4Gb is asking for troubles this is a close call and depends a lot on how much your OS things it has to use.

4Gb might work fine if all you're doing is playing videos. You didn't say what OS you're using, but you'll want to look at the minimum requirements for the OS and how much RAM your video player uses. If you have an SSD, virtual memory won't be terribly slow if the OS needs to use it. Anti-virus programs can be major memory hogs, as can the Chrome browser if you keep a lot of tabs open, so factor in any other programs you'll be running on the machine.

You're going to want 8Gb eventually, but hopefully RAM prices will have come down by then.

That's my plan,waiting for prices to drop to get another 4gb ram later.This system I will build,I am planning on win 8.1 on a ssd & obviously nothing memory intensive will be running in the background while watching videos(except maybe utorrent). I am already used to running win 7 on 4gb ram with an ancient 2nd gen pentium dual core & I believe win 8.1 is a bit more memory efficient compared to win 7. Only reason I am upgrading system is because my processor regularly hits 90% usage while playing high bit rate 1080p 10bit h264 videos for which there is no hardware acceleration.

utorrent is pretty I/O intensive especially when downloading at high rates. I would close it before watching a movie if you want to minimize dropped frames, even on an SSD and a multi-core CPU.

Hi everyone. Just wanted to say thank you very much to madshi for madVR. I'm currently trying out the tone mapping for HDR content on my LG B7 OLED and it's fantastic. I have always used the Active HDR mode of this TV to improve HDR10 and madVR gives me a similar experience, but better.

Compared to Active HDR madVR is better at preserving details in bright spots of movies. For example in the clouds at the beginning of Sicario some small details are lost with Active HDR but stay visible with madVR, even with highlight recovery set to none (but even better when activated). The overall image looks very much the same apart from that at target peak nits of 600 to 700.

Even more important, madVR doesn't suffer from brightness pumping like Active HDR. When white subtitles appear on the screen Active HDR reduced the overall brightness of the display noticably. I hated it. Solved with madVR.

Most of the time Active HDR and madVR tone mapping look very much the same, and better than standard HDR10. They seem to agree a lot on how the picture is supposed to look like, which is a good sign I think.

One thing I noticed: There is a big brightness difference between target peak nits 500 and 501. I don't know why, but there seems to be a magical threshold. 501 is the brightest setting, 500 is much darker, comparable to setting it to 800-900 but with more need for highlight recovery. I don't know if this has to do with the TV or madVR. It's not important anyway, just interesting.

So, thank you again!

@schnief: careful with those subtitles in HDR mode...if the subs come from an srt, I'd make them medium gray or even darker...

Actually not downloading but seeding at ~4-5MB/s(a 50mbps connection),will it still be an issue with a ssd & ryzen 1200.

@mytbyte: Mostly PGS, unfortunately. I don't think those can be dimmed.

I imagine then that PGS subtitles on HDR movies would already be somewhat dimmed by the authoring facility...if they know what they're (should be) doing, that is....

I'd rather suspect utorrent's stupid ads, perhaps try qbittorrent.
You can also give the processes different I/O priority, e.g. with Process Hacker nightly.

i'm pretty confident to say that an I/O operation an HDD can do is nothing for an SSD.

the HDR measurement tool included in the latest test build doesnt seem to work for me. no file is being created and gpu load stays at 0% all the time. could this issue with my rather old GTX760M be related to the one with b&w picture when using "highlight recovery strength" other than none, which has been fixed in the meantime? that some GPU functions are used which are not already included in case of my NVIDIA GPU?
