"black spot" on the YAMAKASI Q271...Need Help

post #1 of 11
Thread Starter 
Hey guys,

Recently I purchased one Yamakasi Q271 on ebay from ONE SELLER(don't give name now) with good reputation after tons of research. Got it last Friday and started to test it during the weekend. Found one stuck pixel in the upper-left area which is unnoticeable except all BLACK. But there is one "black spot" in the right-upper area where is close to the center. The reason I call it as "black spot" is that I can even see it 1 meter away from the screen!! And I can see it closely even when screen is all BLACK background!! Come on, I bought this monitor for some Photoshop work so this "black spot" is kinda of bothering me. I am not sure if it is dead pixel because it looks bigger than ONE pixel. Any experts here can provide some supportive information for me?
Thanks a lot.

Photos are taken by Canon 5D Mark II w/ 24-70.








There is also some shadow on the bottom of screen, like this photo.

Definitely a dead pixel or so. The gradient I think just comes form it being a lower grade panel.

Is that a panel with tempered glass? Looks like a mite of dust or fuzz or bug to me. Probably stuck on the inside. It is obvious that it doesn't correspond to the pixel grid, so it isn't a dead pixel.

Dude, look at it again pls. This is not like dead pixel. There is black between them.

Agreed. I also got some information from 120hz. This "black spot" is more like manufacture faulty. I can see it even 1 meter away from this monitor. This is not a tempered glass. How do you think the last picture? Thanks.

Oh man, you are screwing with me kevinslove.

I feel the need to disagree with you simply out of principle. I kept seeing your name and thinking the forum had bugged out on me and changed my name.

Concerning the "shadow" at the bottom, that is a standard "defect" of all these panels. There's nothing you can do about it, that's just the way they are. I use "defect" in quotes, as as far as any of the manufacturers are concerned, there's nothing wrong with that.

If you don't have tempered glass, and you can't rub it off, then I'm forced to conclude that something got stuck behind the outermost panel in manufacturing - it's a defect that is impossible for you to really take care of. You can try tapping to see if it's loose, but otherwise, not much you can do.

Then it should be a "big dust". But in the photo, it is more like dead crystal something. I am planning to get an exchange or return. By the way, I can even see it under black background but need to be close. With other color, always hardly ignored even the time I'm typing now.
