Could you please use the template from the first post to share your complete settings? It makes adding new values to the spreadsheet easier and more consistent :)
[Nexus 4 General] K3yMaster:
I know root is required to set these values, but is it needed continously? The reason I ask is that I have apps that dont work on rooted devices, so I usually just root, do the work and then unroot.

Can this approach be used?
[Nexus 4 General] danslecarton:
Is it possible to add the 'Date added' column so it's easier to see, which settings I tried and which I didn't?
[Nexus 4 General] kwerdenker:
The changes done by the app are not saved to any non-volatile memory. They are gone after the next reboot and to change them again, root is needed. So you might be able to change them and unroot but you would have to do this after every reboot. I'm currently not 100% sure though, because I think to remember something about the gamma values resetting if the app/its service is not running in the background. Have to do some research to give you definite answer on that.

I think this is a great idea and if ngo supports it too, we can add the date of entry to the settings from now on.

[Nexus 4 General] calyxim:
It is much darker than the one x. Your chart can't be more accurate than my and 3 other mates' eyes.

I can safely say that the n4 is 20% darker than the one x on full brightness. If not more.

Why fan boy?
[Nexus 4 General] eep2378:
Been running these settings for a couple days now. I'm liking them a lot. Taking the red down really provides more accurate colors overall. Not too saturated:D
[Nexus 4 General] kwerdenker:
Sadly there are no source links to where Billy Madison got these tables, so the following is more of a generic "measurement vs. perception" argumentation:

The tables referenced in the post show brightness values in candela per m², which is the SI systems standardized unit for luminance a.k.a brightness. To get these values, they would have to be measured by some kind of sensor other than the human eye. Assuming the measurements from both tables were taken under the same conditions by the same sensor in the same test procedure and thus had most/all of the factors for variance other than the emitting device itself removed, they would be standardized enough to be called factual.

Now, if we compare this to your type of testing, you are pitting four different sets of sensors (yours and your mates eyes) in an uncontrolled test setting. Humans have a very colored perception of their surroundings and are in most cases not an ideal away to take measurements of physical values like in this case brightness. Your eyes for instance adapt their sensitivity to the amount of light available in your surroundings. This is great, if you want to see in the darkest night and the brightest day, but it's not so great if you want to measure and compare brightness values.

Now, before you get angry or anything: I'm not saying that the HTC One X wasn't brighter than the Nexus 4 when you done your comparison. There is always a bit of deviation in the production process of displays (this test by anandtech for instance has a bit different values that the ones posted by billy madison, but this could also be attributed to a difference in how the testing was done though). I'm just trying to argue that saying "[the measured values] can't be more accurate" to what you and your friends saw, is a rather bold claim :)

Oh and btw: calling someone a fanboy just because he has a different opinion than you isn't necessary and does not help in bringing your point across.
[Nexus 4 General] Chad_Petree:
Can somone with the one x try to make the nexus' screen look as similar as possible ? The one x's screen is amazing, my favorite screen , the nexus 4 screen is a similar technology so it shouldn't be that hard to achieve

I bought FauxClock to adjust the gamma and it was a lifesaver. Since everything else other than the Screen tab was irrelevant, I started using his kernels to improve my terribly disappointing battery life (currently using 006b01) and they've helped. However, now that I'm seeing word of the FauxDisplay, does that mean further adjustment of my screen will require purchasing another app or will those changes be included in FauxClock with a less-expensive app tweaking just the screen offered or what?

[Nexus 4 General] undercover:
Really good job with spreadsheet guys. Whoever did the overhaul get a massive THANKS! Also, please put as much info in description especially when basing setting off someone else. User that is close to mine but said that it was a bit too blue just revealed that quite possibly his display is cooler than mine :thumbup:

This way we get some reference on how varied displays get.

Also, has ANYONE got their blue over 1.8 gamma? Display tester is the app and I used it on about 25% brightness. Adding gamma values to description helps a lot too (like I did). That's the best reference you can get when choosing setup. Say mine are as close to properly calibrated as possible, amoled one was 2.4-2.6 gamma in each colour (RGBYCM).
[Nexus 4 General] resynx:

Why should it be a necessary purchase to current owners of FauxClock, most of whom bought it just for the features that FauxDisplay sounds like it will have? There should be two products:

* FauxClock - Kernel settings control and screen tweaking - $5

* FauxDisplay - Just screen tweaking - <$5, perhaps $2 since it's a single-feature app, like Franco's lame RGB thing that he charges $2.50 for.

Since Display will be a subset of Clock, but with more features (or so it's been implied), if he doesn't roll those additional changes (I'd add the ability to save display settings as presets) into Clock it would be a slap at his early adopters. It'd be like saying, "Thanks for buying my app to adjust your screen, but now I've got an even better app for doing the same thing, so if you want more control, pony up some more cash."

It's totally cool to make a cut-down, screen-only app for those who just want that, but not at the expense of screwing over purchasers of the full tool.
[Nexus 4 General] kwerdenker:
I understand the point you are making but I think there something else to consider: "You buy what is, not what will be". You paid for the features the app had at the moment you bought it. Most of the times you get additional stuff through updates without paying extra but that is not guaranteed.

faux hasn't said anything about the pricing of the new app, so it might be best to see and wait what it'll be in the end. If it's just two bucks and has a lot of new features, I'm more than willing to give him something extra. We have to consider the time and effort that goes into making new features. The dev deserves to be paid for that I would say.

Oh and before I forget to mention it: faux said on the kernel thread, that there will be something extra in fauxdisplay for those, that already own fauxclock. He didn't mention what that would be though.
[Nexus 4 General] DirkBelig:
I'd like faux to explain his intentions himself rather than speculate; which is why I asked. My point is that if he breaks out a subset of FauxClock - the one Screen tab - and makes it a free-standing app, but then adds in extra useful features and demands a 2nd purchase, it'd be pretty cheesy. It'd be like Adobe making a Photoshop Lite edition with 10% of the features of the full PS, but then adds in a slew of stuff exclusively that would've been of interest to the users of the full version.
[Nexus 4 General] kwerdenker:
Judging from his responses on twitter, it indeed will have extra features that will not be present in fauxclock.

If you only got fauxclock for the purpose of calibrating the screen and not also as some kind of donation or thank you to the dev, faux seems to be willing to give out refunds judging by this exchange: question and answer.

[Nexus 4 General] eep2378:
Exactly. The colors can be adjusted to look "real", however you can make them a bit punchy too. The big improvement with gamma controls is you can get your gamma curve as close to 2.2 as possible. That will make your colors more accurate and punchy instead of washed out look with inaccurate gamma. If you want oversaturated, blown out colors look elsewhere ;):p
