    hello everyone. so i bought a new iMac 27" roughly 2 weeks ago and i just opened it at first. so of course the first thing that i did was to put my new machine through the yellow tinge test.... and guess what... IT FAILED!

    at least that's what i thought initially. but as i looked more and more i thought to myself, hmmm it CHANGES when i move my head from side to side and up and down. as i moved my head, the "yellow tinge" DISAPPEARED! i didn't just want my own opinion, so i asked someone else to come by and check it out. i asked her if both the bars looked the same, she said "NO!!" and then i told her to move her head around as i did, then i asked again. she said "ooooohhhhhhhhhhh" so it couldn't have been that my eyes were playing tricks on me.

    i attribute the yellow tinge problem on viewing angles. the screen is so freakin huge that most people are not centered when they look at the screen and thereby creating a tinge along the bottom and sides. the yellow would switch from right to left and vice versa as i moved my head to the opposite side and disappearing the direction my head is going to.

    this theory also falls in line with the 21.5" screens not sharing this problem because the screen isn't big enough for the person move their head around and notice the color changes.

    maybe this phenomenon is unique to my machine. maybe it is the actual reason why people are seeing a tinge. maybe there are actual yellow screens out there. maybe it's all of the above! i want to hear what everyone has to say after they have tried moving their heads slowly from side to side and then up and down. do you see a difference in color? or is it still uniform?

    :D waiting to hear from everyone

    I guess Macs are for sitting hours on end in front of analyzing the looks of them while Windows machines are for actually getting work done. :rolleyes:

    Sorry pal I consider 21.5" monitors small. There's a ton of 21.5" screens with the exact same problem. Every single one of them in my apple store.

    So sick of this illusion/viewing angle nonsense. If you are looking at the display straight away, white should be white NOT YELLOW. But if you can live with it please by all means keep it. It's a good thing.

    the fact is, at least in my case, that the screen ISN'T yellow. it's the angle. if it was indeed yellow, then it would have STAYED yellow.... correct me

    I'd say the initial look of my screen varies according to what I've been viewing previously.
    Early in the day, it invariably appears to me sparkling white.
    If I've been on the internet in my kitchen area for a while (looking at a ghastly cheap monitor with blue tint I have connected to an old Powerbook, under flourescent lights), when I go in the other room and view the iMac again, it looks distinctly warmer.
    At night, under room lighting, it generally looks less "freshly-laundered" white than when I use it during the day in natural light. Conversely, if I've been reading a book under tungsten lighting, when I go back to the screen it initially appears extra white for a time.
    I also notice that if I take a break to watch TV for any major length of time, when I return to the iMac the display appears less sharp for quite a long period, probably due to my eyes taking a considerable time to adjust fully to the sharply contrasting viewing distances.
    Just saying.

    I had someone hold my iMac upside down because I was curious what it would look like. The yellow then appears at the top.

    Here is a long discussion on the topic -

    Please use your eyes in future "search forums" box at the top the screen.

    Did you not think for a second "Hmmmm Perhaps there's already a thread on this issue" :rolleyes:

    not a "viewing angle" issue...

    If that were true this issue would be put to bed... but I am on my 4th iMac and guess what, it's yellow no matter how I view it, or where I position my head.

    I am sure we are all very happy for you that you can make your iMac yellow/not yellow at will... Just keep moving that head around if that is all it takes.

    "Just keep moving that head around if that is all it takes."

    :) I have the 21.5 NVidia & I have Yellow Tinge on bottom of screen.
