Problem with blue color in OLED How to tune?

attaching 2 images

1. a picture shows that the blue can be seen from black to blue from level 6
when the rest of the colors start at level 1

2. you can not increase the brightness of the screen, because the bright colors lose details
in picture 2

You need to do a proper calibration of the display. To do this you need calibration software and a meter. I recommend ChromaPure with the Display 3 PRO - it's by far our most popular package: http://www.curtpalme.com/ChromaPure_EyeOneDisplay3.shtm

Then to calibrate follow our guide: http://www.curtpalme.com/forum/viewtopic.php?t=35322
It'll walk you through step by step.

Good luck and welcome to the forum!

No, that would be incorrect.

You are assuming you have a problem because blue output appears reduced below level 6 in your screenshot, but that's not necessarily correct. It's the total response (greyscale/gamma) that matters. That's where the tools I recommend come in. It's the only way to correct set your colours. You may not even have a problem at all. How do steps from 0 to 100 IRE white look?

Turning up blue on the low end to match the others may completely throw off your greyscale. Blue response to our eyes is different from others because of the differences in wavelength, so the answer isn't to get them to all look the same. That would be incorrect. You don't simply turn up the blue gain to compensate as that isn't necessarily the right thing to do.

The right thing to do is to touch nothing and measure the greyscale/gamma response from black to white. That's what the tools I recommended are for. Then you decide what needs to be done. In other words, you need to do a proper greyscale and colour calibration of your set. Not blindly fiddle with controls.

Just blindly turning up blue on the low end is the incorrect thing to do, but if you want to do that just turn up blue on the low end in your TV's service menu. You haven't indicated what display you have so it's impossible to be more specific.

Good luck.

Kal

How can you turn on the blue ?

the screen has blue control
brightness i put more brightness - It changes the brightness only in the brightest colors (where no brightness is needed)
Saturation i put on 5 from 1 - no difference ( can be too little blue adds more white to a blue color)
Shades i put on 5 from 1 - It changes for ( can be too much red in blue )

but do not see a difference in blue from 1 to 6 Too dark
in this site

http://www.lagom.nl/lcd-test/all_tests.php

I brought up OLED lighting (backlight lighting - did not help blue)
I raised the brightness to a maximum of 100 (hardly changed in blue 1 to 5 in blue look black )

I do not understand on the web page - do I need the blue at the end (number 32) to be as blue or white/blue as possible???

Turning up the blue low end is usually done in hidden service menu. Some TVs will have a full blown CMS (colour management system) available too that lets you do lots of adjustment. Every TV is different, so the menus will all be different. I donít know what TV you have.

Keep in mind too that normally the controls in the service menus are meant for doing a full blown calibration with a meter and software as I recommended in my original post above. They're not places people should be tinkering in blindly (usually).

I canít explain what that other website is telling you to do. You should contact them directly if you have questions about their instructions.
