Nullack, how many times do you have to be told to ignore old Studio RGB standards? Every video codec/renderer decodes to 0-255 RGB, your monitor displays 0-255 RGB, that's all that should matter. 16D isn't even a real term.

The simple fact is, not everyone agrees with Foxyshadis. I would hope you to have the maturity to accept that your own theories may not be shared universally by all. Many people particularly on the consumer electronics side consider TV level calibrations to be the right way to go on any TV, including digital ones being fed digital signals from a HTPC.
However foxyshadis if you bothered to actually read my post, you would see *Im trying to do PC level* calibrations. Even a most cursory look at my post would have given you that. Instead of going off on an unrelated point, how about addressing what I actually said, which is about finding PC level 4K calibration test patterns..... |

Huhn I know you have allot of video knowledge and I'm thankful for insights you have offered in the past In this case though, I really dont think you get whats driving what Im asking and sometimes I get the impression english isnt your common language. Ill try to explain. The thing about test patterns is they need to be "reference quality". They need to be verified they are correct - for example the ISF have a process for this and they explained it when they published some ISF test patterns. As you know there is allot of different test patterns that do different things. The reason I want 4K test patterns in particular is to send *native" resolution images to the *native* resolution of the display so as to avoid any non reference artifacts in the image. I gave the example of sharpness tests. Those sorts of test patterns are useful in native resolution because of how fine the detail gets with testing sharpness. As you'd know, 4K is allot more pixels than full HD. The value seems obvious to me in these sorts of cases to be able to do native resolution test patterns.
Im not arrogant and I do listen to contrary arguments that are rational. If indeed your convinced I'm wrong about this topic, then please explain why you think so. Just saying that I dont know doesnt contribute anything of substance to the discussion. |

like I already said levels doesn't matter if you 100% know how they work.
that's mean you know the render/desktop side, the GPU side and the TV side of "levels". just a small example. if you set the GPU to YCbCr or limited range RGB than you will not get information in the WTW and BTB parts no matter what. if you take a 1080p test image and want to use it at an UHD screen than you use black boarders for that (zoom 100 %). the image in the middle is still bit perfect. works with http://www.lagom.nl/lcd-test/white.php and works with these test pattern: http://www.avsforum.com/forum/139-di...libration.html |

Ok I see. Just dont scale it when using test patterns lower than the native resolution. While I realise that would work, I would prefer to deal with things like sharpness at full screen so I can carefully try to tune into the reference standard. Thanks

NN x2 scaling should work for most test patterns too.
a good sharpness test picture works like this: http://www.lagom.nl/lcd-test/sharpness.php so a smaller picture helps a lot to do this test. this test for example isn't affected really by NN x2 scaling. |

So, I have finished playing with profiling, so I try to summarize what I understood so far. And thank all of you for the great help.

- it will use dispread.exe with predefined (!) .cal (calibration) and ti1 (testchart with 154 patches) to create a measured .ti3 file - then colprof.exe will provide the necessary .icm file from the above .ti3 file to be able to use targen.exe in the next step As I reported, I don't have any problems with this method. So I went for this. Quote:

Is it possible to get non oversaturated colors on a high gamut display using dispcal and a color managed program?
For example, if I choose sRGB tone curve, and create an icc profile and import it in firefox, will colors look normal? I still need a monitor (returned the pg279q lol). 4k bluray is coming in less than a month and is has a larger color space and is 10bit. The new dell ultrasharp's have ~98% dci-p3 and are cheap ($700) for the supposed quality you get; gb-led, 10bit, 1440p etc. They currently seem like a good purchase. What about madVR? Do you need a 3Dlut for proper color space conversions, i.e rec. 2020 to .709? What about 4k bluray on a display that has high dci-p3 coverage, works by default? |

For madVR you only need a 3DLUT if you want to use your display's true gamut but if your display's native gamut is close to one of the options in "this display is already calibrated" madVR does the proper conversion from the source gamut to the display's gamut. Options available: BT.709 SMPTE C EBU/PAL BT.2020 DCI-P3 The one important option missing is AdobeRGB but for those new ultrasharps DCI-P3 would probably work pretty well. The biggest issue I have with any wide gamut display is streaming video, I have never found a method to correct streaming video. Not really IMO, only if you aren't really very close to sRGB.

So unless your monitor is in Photoshop 24/7, there really isn't a point in wide gamut. I guess you could get accurate colors on the web, but content is basically all sRGB, so you're just wasting money. With UHD and madVR you could benefit, but a higher contrast ratio is probably more important than a larger color space, which rules ips panels out for viewing, as opposed to creating. |

I would even go so far as to say that there are large negatives to a wide gamut display unless your monitor is in Photoshop 24/7. A DCI-P3 OLED for movie watching with madVR would still be quite enticing, assuming I could get any content in wide gamuts.

I got my UP2716d today (ordered it before our discussion on wide gamut).
The first thing that came to mind was wow, vibrant colors, not over saturated and bad looking. It looks a bit like a samsung phone, which imo looks the best out of all phones screens. This is the best looking display I've seen, and it's not like I paid 2,000 for it, only $700, which is less than my previous monitors. It comes default in adobeRGB color space. sRGB looks very faded, I wouldn't use it, unless I calibrate it. But I don't think I need to use it, because adobeRGB looks excellent. DCI-P3 mode has very nice colors, but it's dim (obviously for movies), but I don't have any content in DCI-P3 yet. UHD movies come in less than a month I think. I have not calibrated it yet, but ran a color test chart in dispcal and I see colors I've never seen before. They don't look incorrect. I can select 10bpc in NVCP with my 980ti. Do you know how to use madTPG for normal calibrations, or is it not good to do that. IIRC madTPG has 10bit output? |

I've found something a bit weird. The monitor on default is in "standard" mode. Everything looks great, and dispcal shows 100%sRGB and 99.7% adobe RGB and 93% dci-p3. When I switch from standard mode to color space, and select adobe RGB, reds turn orange... sRGB emulation mode also looks makes reds look orange. wtf lol
