Really, the only purpose to document all these settings is for statistics. To show that more Nexus screens come with x-color tint than y-color. Even then, you're trusting people to know what white and gray are supposed to look like. I've seen how most people set up their TVs - they're usually wrong.

There isn't a HUGE variation in the differences. Each screen isn't a special snowflake. There's a relatively small, finite number of different screen settings that work for all screens.

This will give people a narrowed-down list to try first instead of spending hours experimenting.

It doesn't take hours, it's a pretty easy process:

Color multiplier is white balance, which also affects overall color tone. Get two things: a blank white screen, and a pure black screen with white text (settings is easy if you have gradient disabled.) Use these, and go with what you think white should be, unless you have a good reference or a calibration tool. For example, I dropped red/green because my screen was too yellow stock. I then found that I could still almost see the individual red pixels sticking out of text (best way I can describe it), and looking at my home screen felt a little too "pink", dropped red a little more until it looked fine.

Next is gamma/offset/whatever which is the adjustment of everything in between white and black. This one can be trickier because grays can easily look too red/brown, too blue, too yellow, etc. and on these screens the gray balance will change depending on brightness. Yes, sometimes drastically (see: purple tint) This can be a pain if you need to lower greens because green can't be lowered (the screen goes nuts), and the colors don't scale the same, so if you increase red and blue by the same amount one will probably be stronger than the other.

Just from my experiences. And yes, each screen is a special snowflake. Most people are just happy enough with canned settings.

The only thing I would add to that is if you are going to eyeball the whites and grays without a reference, it's better to do it in soft, indirect daylight instead of artificial light, which has various color tints depending on what kind of bulb you use.

What brightness setting should we test this on? My colors look fine it's just it's a bit dark on auto brightness which is at like 1/3 brightness

I usually calibrate at maximum brightness, then double check if the settings are ok at 50% and minimum brightness.

You probably should do this on the brightness setting you're most regularly at.

I personally did my calibration at 50% as I almost never go above that (unless in direct sunlight.) I read in another calibration thread someone mentioned that with default settings 50% brightness is quite close to a "standard" brightness level (measured in IRE) - so I'm going on someone's word, but it looks good and natural to me.

Agreed with this, it'll be different for everyone

Screenshots don't really prove anything.. It's all in how your screen looks in person after compensating for the "special snowflakiness"
Take a photo if you want to show us how different settings are affecting things.

I just noticed... haha true.. But that's the issue. I can't read the black on the gray.... while looking at my phone. What should I adjust?

Still can't figure out what to change. The colors are fine but the darks are dark and hard to compare them to against each other


Edit: I'm stupid! I was using the lowest omap gamma..should be 1 right :/
