As you can see in ss, the color background on the 3 devices is not exactly identical, in the sense that, on the video projector and laptop, the color tint is BLUE and on TV it is GREEN. As you can see it is the same ss on all 3 devices.



video projector model: Touyinger T26K china

notebook model: acer x555L

TV model: Samsung UE32H5030AW

OS: windows 8.1

My dilemma is one: Which reflect the reality of the color? the video projector + notebook or the great Samsung? Samsung which always say they have the best contrasts and saturations on color. I do not understand

I want to mention from the beginning to understand: all devices are by default on color, I did not change anything :contrast, brightness, etc.

Those who still have windows 8.1, please tell me in the section: Personalize, windows desktop background, on the theme Flowers 6, the color tint on the background is blue or green? I'm really curious

thanks in advance

I'm guessing the TV is off, maybe due to full-color (8-bit) vs limited color (16-235) settings on HDMI, and therefore not enough blue getting displayed (blue getting clipped), which causes the green-shift.

the image on the tv is the same on chroma 4:2:0 and 4:4:4 full RGB
so the tv have unrealistic color or laptop+videoprojector?

It seems like you could just do a screen capture of your desktop, load it in an image editing app, and get the RGB values for any pixel you pick?

I was about to state the same thing. The only accurate display is one that has been calibrated. Given that you have a computer, you can load up some test images. Also, you might want to make sure someone who does the calibration with test images has a very good hue perception. There are tests for checking your own hue perception, with a good online one being:

That said, the above test is hard to perform on a poorly calibrated monitor in the first place. I am on a calibrated monitor, and I also have no issues with color blindness (I just scored a zero on the above test, where the lower score is better, with a zero being perfect).

Also, it is hard to get colors correct with just an online test. You really need a physical reference test image to compare against the monitor or better still, an actual calibration system.

I am a fan of the opensource DisplayCal system myself.

My monitor is horribly calibrated (intentionally to reduce eye strain) towards red, low blue, and brightness too low, yet I can still get a score of 2 on that test using it. SO, I don't think that test really does a lot except tell you if the person taking it is color blind.
