First, I hope I'm posting in the good section, otherwise sorry.

My monitor have several "problems" but for now I'll just talk about one  Grin.

Since some weeks I have a dark "wave" on the right, it's about 1.5cm large and it's taking almost the full display height.
It's not moving, it's always the same shape and it won't disappear after several hours.
When I switch on the screen (when it's "cold") I see a lot more this dark zone (~4x bigger), it returns to its "normal" size after 3-4 seconds.
I suspect my second monitor which is at the right of my Eizo, like a magnetization effect but LCD screens are not supposed to do that (?).
My second monitor is now turned off (1 week).
I tried with DisplayPort and DVI, I changed power cable connection (UPS), nothing better, it really seems that it's the screen itself. (I'm pretty sure ...)

It's only visible with mid-dark tone, like dark green or dark grey.
As you can see here (Will try a better shot)
To the right, the rest (Moiré, artifact) isn't visible in real.

Any help is welcome Smiley.
Thanks in advance.

Yes, thats a weird effect.

It sounds like you've done some testing, but have you tried a different video card or computer system? Often a video card can be the culprit. This might be the last test before you contact Eizo Tech Support. You should be under Warranty still, so if its a panel or backlight issue, Eizo would be the one to contact:
Eizo Email Support: <support(at)>
Eizo Front line Customer Phone Support:   M-F 7am-7pm MST:   888-900-8383

Hope that helps.

Thanks for your response.

I've just tested with my laptop (screen on for 1 hour), but it's the same.
It's like a "burn" between the pixels and the filter, but that's just my feeling.

Otherwise I see since the beginning (2010) : (prepare for some whining Tongue)

- Some "fingerprints/mark effect" when I scroll a page, they're always at the same spots, I thought it was some moiré side effect because I can see moiré pattern with moiré test.
I don't know if it's normal for a LCD, that was my first LCD screen ever, had a Mitsubishi 2070sb before Wink

- Some (it seems) backlight bleeding on the upper side, left and right of the internal sensor hole. My i1Display Pro won't see it right now (because the bleed can change with pressure and it's only my second day with), but I can see it (I'm not the only one) within a 80cd/m2-120cd/m2 range and with a dark or lighter room. Again I don't know if it's "normal", I see it almost only with black color, and the most disturbing is that the shape of this bleeding is moving if I press the sensor block (so moving the screen or incline it can be a problem).

I can't assert these are real problems (it's my question in fact) because I'm not a specialist but I've good eyes so I had to tell it Smiley

I'm not in the US in fact, I'm in Switzerland.

I already had a screen swap with support (this time for a left side blacklight bleeding), but communication is quite difficult with them (first time they gave me back a Flexscan screen Roll Eyes) and they have never confirmed or denied my observations. If I write a message in French (west of country) and not in German they'll send me an Eizo non-technical employee who will say there is no real problem without using any instruments (Support is normally done by another company not Eizo itself).

I have 3 months warranty left, so I prefer to be sure what I'll say to them.

Aside of that, I honestly think there is a good reason why this model has almost disappeared of the website and that the new one have the sensor on the down side.

Nevertheless, this screen is really good and I don't want another but this problem (or these) scares me when it appears so close to the warranty end.

Sorry for this message, but there aren't a lot of places where to speak about Eizo. Grin
