The Spyder3 is not a good device to use as a reference. For one thing the sensor was designed before LED backlights were popular and it is not able to accurately measure white point or indeed colours on LED backlights. It isn't terrible, it can be used for a fairly decent calibration for general use - but don't give too much weight to anything it's reporting for you regarding colour gamut or white point.

Another issue with the Spyder3 is that it has terrible low-level light accuracy. That means it is not able to accurately measure the black point of a monitor and tends to overstate it. I'd always advise taking these measurements in a dark room if possible, but the lack of accuracy is why there is such discrepancy between your contrast measurements at '0' brightness and others. And also why you got such a poor contrast ratio readings in general. Its successor, the Spyder4, is much better at measuring various things on LED backlights and is also a bit more accurate at low light levels. It's still not all that great for contrast measurements though, which is why I use a separate device for measuring light levels when I review monitors.

I think you misread my post; I have the spyder 4, not the spyder 3.

I am hoping it is just not accurate at measuring contrast, because two of my other monitors that I tested (Benq G2400W and Dell u2211h) both had contrast well below what they were advertised as. The U2211h seemed to get below 700:1 when reviewers are getting just under 1000:1.


Paganister, as far as the glow goes, it shouldn't be noticeable at normal viewing distance unless you are looking at an all black screen, and even then it shouldn't be too distracting. I sit about 2 feet away from the panel when I am doing computer-ey stuff, but a bit farther when I am watching video (which tends to be where the glow is more noticeable).

Hi, i got today an A01 replacement for my A00 one (the A00 has same bleeding as shown by Paganister) and what should i say?
A01 is even worser...the yellowish corner on the bottom left is now ~three times bigger than on the A00, i had them both side by side in the room.

To be honest, I am very happy with the way the panel looks when there is something white on the screen. I don't think I want to take the risk again because of that since 90% of the time I am viewing something like Facebook etc anyway.

How far away do you guys sit from your monitors then? Is this something that might improve slightly the more you "run in" the monitor, like a car motor? tongue.gif

Thanks again.

Edit: Oh, and it's revision Jan 2013 - A00

FYI - it's through Amazon .co.uk. They have been faultless the whole time on customer service, fully recommend them. thumb.gif
If it changes depending on how far you sit from it, that's not backlight bleed then, that would be characteristic of IPS glow - which is a problem with the technology itself, alas.

I honestly still think it's bleed, but exaggerated by the glow. If there is a bright scene on the screen it lessens but it's there when it's really dark. If there was no bleed it wouldn't be there at all. Unless I am wrong?

Also MaxMax that sounds unlucky...

Hello!

Today is my first day with a U2713HM! Its a A01!

I'm very happy with it, but when I did a backlight test...

Do you think that is a lot of baclight bleed? Do you recommend me to got a replacement?
At 0% Brightness

At 35% Brightness

At 100% Brightness


Thanks!

The case on the U2713HM is the cause for the yellow bleed. I have the A01 March 2013 revision, and its still there. Hopefully they fix this issue in the next revision.

If you put pressure on the monitor as if you were tilting it up, the yellow goes away (Asus monitor in pic for demonstration purpose)

The pics seem to look over exposed. If not, it looks excessive.

I'll ask what I ask everyone...... Is the bleed coming through where it's visible in movie or game black borders?

If it's bleeding through that causes distraction then I'd try replacement. You have to be happy.

Welcome to OCN with your first post. thumb.gif

e-ips panels contrast varies alot, often by 30% (700:1 vs. 1000:1) for some reason, so, the lower contrast on your U221H is likely normal.

That isn't what worries me, what worries me is that the Spyder 4 is saying the contrast on my U2713HM is 560:1 when it is advertised as 1000:1, and virtually all reviewing sites get values well above 800:1.
