Have to disagree - the parts are no different to what major OEMs use in their monitors. There are countless cases recorded in these forums of customers reporting problems with products from major brands. We have thousands of very happy customers using these LED displays [here and the Far East] and recent posts in this thread proves this.

My screen seems great apart from the low quality stand. For the price I'm a happy bunny.
There's only 2 possible reasons why this can happen: At a higher brightness, the monitor will draw more power which means more heat and noise. The sound usually originates from the inverter and is audible sometimes. We know of a major Japanese OEM and panel vendor who recently had issues with this in their TVs. The noise is can be amplified by metal objects in and around the monitor [radiators etc.].
The 2nd cause is EMI interference originating from devices such as PC hardware, mobile phones and even your watch. Is the power adapter anywhere near the monitor? Try moving it as far away from the monitor as possible.
Just to add, if the volume on the speakers is set to max but the computer volume is set to low, this can result in an audible buzz from the speakers. It also works the other way [low speaker volume but max volume from PC].
Its just strange that it exactly matches the pattern of EMI interference that causes the exact same audiable issues and sometimes PSU coil whine - usually a monitor buzzing will be pretty constant except when theres a large change in brightness, dragging a window around the screen shouldn't cause a change in the buzzing on the monitor, but it will cause the CPU and/or GPU to work harder - its possible something in the monitor is faulty and ultra sensitive to the EM from the rest of the PC.

There is nothing near the monitor to interfere. The power pack is as far away as possible. If i move it any more away then the monitor will clean lift the powerpack off the floor - it's at full extension.
There is nothing else near the monitor. No phones, watches, nothing. I have a Dell 2405FPW and i also have a HP LP2475W here and neither of those make even the slightest noise, they are both ultra silent. Only my HZ27WA makes this buzzing sound.
The noise does only happen when the monitor is displaying large amounts of white. On these forums the monitor is silent, but on wikipedia pages it's very noticeable.
I played with the monitors OSD to try and narrow down what causes the noise at it's related to the contrast settings. If contrast is at 100 then the monitor buzzes away on Wikipedia pages. Lower the contrast and the noise gets lower and lower until it fades away to almost nothing at 0% contrast.
Change the brightness or ECO Mode settings make no impact at all on the noise - only the contrast slider.
The noise happens even if all speakers are off. I have no audio source going into the monitor at all and it's volume is set to 0%. I use an external AV receiver for my all my audio. The noise from the monitor occurs no matter if the AVR is on, off or completely unplugged.
Glass Pros and Cons:
Pros:
Better contrast
Sharper image
I presume the difference is marginal, but havnt seen the glass-less version so this is based on my own reading.
Cons:
Super reflective
Smudges show up easily
I love my glass HZ27WC, but if Hazro offered me a perfect glass-less version I'd take it tbh. Catching my mug in the screen can be immersion breaking in dark games lol...

Sharper image? lool i think the only thing that glass brings to the screen is vibrancy in blacks and colours.
However im digital designer who has worked in photoshop and illustrator for years and i can say, compared to my macbooks ( which are glass) hazros glass-less version is amazing, its just truely amazing. I really have never seen anything like this, except the apple cinema display. And boyyyy Im only 20 years old and i splashed out 500 quid for this... Bloody bargain to me

I got one of the non-glass ones and am very pleased. Well worth the wait.
No buzzing noise from mine fortunately.
Having seen some of the previous comments about the stand, I bought a VESA desktop stand from the Rainforest and can rotate the screen to portrait if required.
Thanks Hazro and OCUK - for £375 this was a complete bargain.

The noise doesn't change at all if I alter the monitor's brightness, and there aren't any metal objects nearby.
I've moved my PC as far away from the monitor as my longest cables allow (over 2.5m) and turned off every other electrical device in the area. It doesn't make any difference.
As DarkBahamut found, it's quiet on dark pages like this, but if I switch to Mobipocket Reader, fullscreen with a mostly white page, the noise instantly becomes loud and high pitched. I'm not sure how that fits with the idea that it's caused by interference from other devices.

There seems to be a lot of miscomprehension in this thread. You are comparing two monitors that are exactly the same in every way except that one has a piece of glass infront of it. You aren't comparing a matte surface to a glossy surface - you are comparing a glossy surface to a glossy surface with some glass infront of it. http://forums.overclockers.co.uk/showpost.php?p=19295035&postcount=256
I had the same effect, with the audio volume put at a high level on the screen. I think it is not a fault of the screen; there is some noise on the sound output from the computer, and the screen amplifies it. After reducing volume to a reasonable level, I don't hear this noise any more (and disconnecting the audio cable there is no noise at any reproduction level).

I think it could the cable your using........ I only ever use Optical cable for sound... so Im not too sure.
speakers are ...ok but theres no real oomph to them

using the cable that came in the box.
Haven't tried with HDMI yet, will do when I hook up the ps3.
As i mentioned earlier in this thread, I wasn't too pleased with the backlight bleed on one side. Here is a photo of it next to my DGM 24" VA screen.
obviously the colour ballance between the two is significant, but you can't notice this in real life.
Overall it is darker than my old screen which is good, however it is really non-uniform on the left. The bright left hand edge is quite noticable in films...

Wow that is ridiculous bleed. Mine is nothing like that, so much so i struggle to even tell when the backlight is on at all sometimes when the screen is black.

After following this thread with interest I can now say I would never spend this much money on a product/products that has [what seems] and endless amount of issues. I would rather just wait till OCUK get the Samsung S27A950D 27" in stock and buy a monitor I can live with and have some peace of mind.
What really worries me about the Hazro range is just how long they will last before they give up. I have a feeling it won't be more than 3 years. I like to buy with confidence and these monitors don't inspire that after what I have read.

I've been playing around with the contrast too (using software since I have a HZ27WC) and it definitely makes a significant difference. I need to turn it down to around 40% before the monitor becomes inaudible, but even at 95% there's a noticeable reduction in noise.
Setting contrast to 90%, I upped the backlight brightness a bit to compensate, and tweaked the gamma and other settings, using this online test to recalibrate it as best I could.
It's still easily audible with a lot of white on screen, but the noise is isn't so loud or high pitched, and definitely isn't as annoying.
