Ok thanks will do. The picture quality does not look the same when i view it form the top or from right or from left when standing up or sitting down. I thought the picture quality should look the same where ever you view it from

MrKay. Mine looks the same as yours given the lighting conditions. It is not black when the screen is on with no input.
I imagine this is the IPS "glare" people have mentioned.
When I first turn my monitor on I get this effect. At first I thought it was a problem in the lower left corner, but then I noticed that the glare changed position as I moved around.
If I stand about 10 feet away and look straight at the screen, the glare looks fairly even.
I think this is normal for an IPS display. As I mentioned a couple of posts ago, I went and had a close look at an Apple IPS panel and it looked much the same when I turned off the input.
Similarly, the viewing angles are not what I had hoped. They are much better than a TN panel, but the colour changes quite drastically with sideways viewpoints, as does the brightness.

I am coming from a 24" Dell S/PVA panel, and I expected this to be as good, if not better, in terms of viewing angles and deep blacks, but this is not the case.
Nonetheless, I'm pleased with it for the price, and very glad I didn't shell out three times as much for a similar, slightly disappointing experience, with an Apple or a Dell 27"

What is concerning me is what appears to be a row of LEDs or Pixels (?) along the top of the display, which are flickering constantly.
If I look at this line closely I can see a white pinprick every 30mm or so. These are flickering in a ripple effect and cause the very top of the display to appear to wobble slightly.
I need advice about this, before I make a claim. Does it go away? is there any way to fix it? does it get any worse?
It was a lot worse initially, until I changed power leads into the brick. Is that the issue does anyone know?

Bu the way, my power brick gets quite hot, rapidly, after I power up. It is not too hot to touch, but not far off. I have used the monitor for several hours and it remains at the same temperature, so I'm assuming this is normal

hey ho, John Williams

This is from top view Warning: Spoiler! (Click to show)

This is from right side view

left side view

this view is not a close view. Short from quite a few foot away

Close up view
is this normal with ips display ?

Aye this is normal behavior, I found it marginally more apparent on the Crossovers than my Apple when I tested them probably has to do with the tempered glass . You won't get drastic changes when you take pics in a darker setting by much.

@John Williams, I haven't heard of the flickering pixels before someone else may have experience on here with it but as for the power brick I'd probably change the lead if possible and see if it makes a change. Mine stay pretty cool after 3-4 hours of use, are you at higher brightness settings?

Thanks for your reply Azefore, I've tried three different power leads. The one supplied, plus UK plug adapter, was terrible in respect of the flickering problem. It gave me about a 4mm band of flickering along the top of the panel.
This was much improved by a normal UK power lead. I have tried two of those, and this very thin line of flickering remains with both.
As for the power brick, that heats up to the hot side of warm within a few minutes. It would make a great hand warmer:)

Seems likely that the answer to my flickering problem lies either with the lead or the brick.
I've got brightness set at 80% by the way. I can't seem to enter the menu apart from choosing two settings. I haven't worked out how to move the sliders. Is there a trick to the way you use the buttons to make changes? On the whole though I'm finding the brightness ok, and I've adjusted the colour using Nvidia's tool, so that's acceptable, although still cooler than the Dell 2408WFP.
As I have said, I've contacted AW two days ago but no reply as yet. Not sure whether to ask for a refund before my 30 days is up. that seems drastic over such a minor issue.
I don't really notice it when I'm sat back watching a video or TV, but when browsing it is very irritating and draws the eye. Also, it may get worse.

So a bit of a dilemma. Maybe, as you say, someone else has had a similar issue. Thanks for your input Azefore thumb.gif

The mac mini and macbook air work fine if I connect them to my tv (don't have a second monitor to test with).

Man, that is strange.

Is your dvi adapter new? I've read the older ones had some problems.

Hey everybody, I'm making my internet rounds trying to find an answer before my monitor explodes on me.

Anyway, my Crossover 27Q is starting to have flickering issues after 3-4 months, most likely tied to the crappy blue LED driver board. Now, I'm trying to line up a replacement board with my seller - greensum. He sent me photos of a possible replacement board, VLD0100, I hadn't seen anything on this model anywhere except for some Russian / Korean sites on Google and it isn't exactly the zyglobal-brand green board that AW seems to be sending nor the fif22ld-04a that is some other replacement used. Anybody have any experience with this board? Or know if a swap like this won't cause a catastrophe? I suppose the most basic question would then be: does anyone have any method of getting a compatible replacement board?

Here's what the seller sent me pics of:

And.. I think this the sameish board (taken from a google search)

Sorry for all of the image spam.

Thanks.

how about take the board to a local electrician and have him test it out for you. you've pretty much done most of the work right there parting it out. he can check what capacitors/parts need replacing and you can buy them for $1 on ebay and replace them yourself.


i'm amidst repairing a high end $1000 power amplifier and they have the semantics available on pdf, ordered parts off ebay for $10. only problem is it takes 3 weeks for parts to get here from china..
