Could you tell me what I'm supposed to be looking for/noticing?

----------

Did a quick search myself. Yeah I know what you mean by backlight bleeding now.

I have an LG panel. Im in my room totally dark. brightness max. Keyboard lights off as well just to be sure.

Hand over apple symbol at back.


I tried it 2-3 times and at first I thought there might have been some bleed bottom right corner but as I shifted my head back and forth I think honestly I'm jumping at ghosts. Screen seemed pretty uniform to me.

LG screen, nothing overly noticeable. 1/4 inch of green on left edge and small burst of red on top right corner. Took almost the entire time of the video to notice. Completely acceptable.

do you really have to go looking for a problem? if you didnt notice it while in real world use, why make your self miserable finding something

I agree with you in that if it's not noticeable that there may be something wrong under normal working conditions, there is no real problem. Minor backlight bleed isn't that big of a deal. It's predominantly annoying if it's bad (and you will notice signs prior to testing) or if the luminance falls off significantly when tracking away from the center. Then you'd have dark into light increasing the contrast and pulling your eyes toward the edges of the display. That is irritating. It's similar to how photographers often don't want corners to be too bright. It's annoying if your eyes are pulled away from what you're viewing.

Anyway all displays have some variation in uniformity, so it really does come down to what is noticeable. If you're working on photos or illustrations, uniformity can become a greater concern

If you are spending $3000 why not find the almost flawless display...before your waranty is up.

nothing is perfect, you will always find something. "$3000" ( mine was 2131 with tax) doesnt give you a computer with no problems 100% of the time. No amount of money does. There will always be problems, so using the excuse that it was $3000 means nothing.

Also, theres problems and then theres PROBLEMS. An issue that you have to actively look for in certain conditions, doesnt exsist. I guess what im trying to say, is just to enjoy your machine and stop looking for problems becuase you will find them

I said "almost" it means good enough.

I think what people are thinking is backlight bleeding is actually the green/red hues that A-TW polarizers give. On the flip side, they almost completely eliminate the IPS glow

Read this post for more details.

And this is what NEC says about A-TW films

NEC said:
The A-TW filter is an additional film that is applied to some LCD panels with the aim of improving off-axis viewing of the display by reducing the "glow" effect that can be seen when viewing very dark images at extreme angles on S-IPS LCD panels. While it does reduce the glow effect, it can also introduce a slight coloration artifact that causes the glow to appear green when viewed from one angle, and magenta from another

This shows on mine. My eyes see a little splash of red on the top left corner. My camera sees some green on the left side along with the red on the top right (dk how). I seriously don't see any green with my eyes. Well, I'm not worried about it. I've never even noticed it until I did the test.
