Hello,

I recently purchased two of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16824009422

One of them looks fine and the other not so much. Both seem to have a slight blue tint to them, although the one on the left is much more pronounced, making whites not so white, and bleeding in to other colors a bit.

Here is a picture of both monitors side by side with a white paint window open for comparison:

Here is the left, followed by the right, monitor, isolated:

I've tried using different cables on the left monitor - VGA and two different DVI cables - and have the same result. I've also tried switching which DVI port they plug in to on my video card, as well as trying each monitor individually. When I try to manually adjust the monitor's color things start to look a bit yellow.

Is there anything I can do about this? Does anyone else actually notice what I'm seeing? Should I just return the monitor I think is bad and get a new one?

Thank you in advance for any help, I appreciate it.

Manually adjusting colors is more than simply lowering the blue levels, you also have to play around with Green and Red to try to balance everything out. It's kind of a hit or miss thing that you need to experiment with.


Getting a replacement may or may not "fix" the issue. Chances are a replacement will have truer white, but you may end up with a monitor that has similar blue tint, or worse, even more blue tint. The blue tint will not go away with time since it is likely due to the fact that the blue LEDs do not have enough of a yellow phosphorous coating.

Just because they are default doesn't mean they are the same. They could have different firmware revisions. Verify that color temperature, brightness and contrast settings are the same.

If you switch the output cables so that the one currently going to the right is going to the left and visaversa does the left still look blue?

If all of that is verified, and switching the inputs still doesn't fix it then I would suggest either swapping it out through warranty, or if you can deal with it just leave it.

I would probably swap it out if the settings match and they are still different.

Color temperature, brightness, contrast are both manually set to the same settings.

Switching cables in any fashion does nothing to resolve the blue on the left monitor.

I hooked the left monitor up to my laptop and the blue tint was hardly noticeable, if at all. Any idea about that?

Colors can be slightly off even if both panels are from the same production batch. Simply try to adjust the color settings on the "bluer" monitor to see if you can get white to look close to the other monitor as possible.

You should also know that LCD monitors with LED backlight can sometime look a little bluish on non professional level LCD monitors. This is because the backlight is not actually white, but "imitation white" or "simulated white".

LED that produces pure white do not exist. The white lit is actually coming from blue LEDs with a yellow phosphorous coating to produce an imitation of white. I believe most of the time they produce what looks to be "passable white", but sometimes there is actually a faint blue tint. This is most likely the issue you are experiencing.

As I said above, when I try to lower the blues of the bluish monitor it looks yellowish; not really a solution.

If the bluish monitor has poor LEDs causing the problem, would a replacement likely fix the issue, since the other monitor seems fine? Will time diminish the blue tint in any way?
