Since Lenovo has said that the dark yellow problem on the Y50 is an issue but they wont offer a fix then im opening this thread to see if anyone can provide a partial solution to this problem.
Some things im looking for
1- Screen calibration - Calibration walkthrough & recommended profiles - can someone provide a how to on how to do this?
2 - Dynamic contrast - Does anyone know how to turn it off or modify it?
3- Any other solution?
Solved! Go to Solution.

The tool doesn't work for me on a Y50 UHD because it opens in a box that's too small to fit the application's options. And you can't resize the box (at least I couldn't find a way). It's an old app not desiged for high-res screens.

I'd like to add that I have this problem as well, on a new unit that I purchased a few days ago. I like every other part of it, but the screen backlight is way too dim, and the yellows are pretty terrible.
I'm hoping that a fix comes around, even if it means Lenovo mails out new screens.
Edit: What's DOS? Really? I'm not sure that denigrating customers using forum ranks is the right thing to do, especially when it's done using computer related terms.

I have this problem, too. After tweaking to no end, I'm no closer to a solution. But I do know this: the screen is totally capable of rendering yellow and the only thing stopping it is firmware. The problem is rooted in the dynamic contrast nonsense that the panel / firmware does.
To test this, start with a screen that has no yellow on it. The following test will compare a screen with a little yellow vs a screen with a lot of yellow. When the screen has a lot of yellow, the yellows correct themselves.
1) Place the Google Chrome icon on your desktop, with all it's mustard yellowness...
2) Use a dark blue background
3) Open MS Paint and fill the canvas with solid yellow
4) Focus on the Google Chrome icon
5) Notice that the Chrome icon is now proper yellow
6) Drag the MS Paint window around and notice it doesn't matter *where* the majority of the yellow is, the Chrome icon always looks correct
7) Drag the MS Paint window off the screen and watch the Chrome icon slowly fade to mustard.
So clearly this is a firmware-related issue and can be fixed. The panel is fundamentally capable of rendering proper yellows.

voodoodrul is correct...the screen automatically adjusts based on the colors on the screen. It's called Dynamic Backlight Control technology, which is built into the display. The Lenovo HD displays are low-quality, white-backlit screens (which is why they're relatively affordable) so the compensation is part of the design.
There's an excellent thread at notebook review on adjusting the screen calibration with an ICC profile paired with some other adjustments. It works pretty well and makes things better. Note it will not make the screen colors perfect, but much better.
Sadly, these screens and the Y50-70s do not live up to the hype (and, surprisingly, the good reviews) and I'm very, very sorry I got one. Well, two actually. One of the screens is better than the other, but we're probably going to dump both units in a year and get something else, probably Apples. It depends on how Windows 10 works.
