HZ27WA, HZ27WB & HZ27WC Problem Thread

[Mr Krugga]

BTW, I'm still having an issue with the display during start up. The monitor just wouldn't turn on from stand by, I tried a different DVI port but that wouldn't help at all.

I'm thinking it's a motherboard's issue since nobody else seems to be having it.

Any way of troubleshooting the problem?

DON'T FORGET DSR!!! YOU HAVE 7 WORKING DAYS (NOT INCLUDING WEEKENDS) TO RETURN ANY GOODS PURCHASED OVER THE INTERNET. DON'T PANIC. AS LONG AS YOU GET THEM BACK TO OCUK WITHIN 7 DAYS IT'S COOL

I honestly feel sorry for OCUK though as this will be expensive and time consuming for them. Hopefully Hazro will step up and take responsibility.

Actually you don't need to physically return the goods within the 7-working-day cooling-off period, you just need to notify the supplier that you're exercising your rights to cancel under the DSRs (do it via email/webnote or recorded delivery letter, a phone call on its own isn't sufficient). Obviously you'd need to arrange for the goods to be returned within a reasonable timeframe, but there's no immediate pressure to do so.

Having said that, there's no reason you should be expected to pay for return carriage if the goods are faulty rather than just unwanted or unsuitable, so in that case you might want to reject them under the SoGA as opposed to returning them under the DSRs.

Well I'm glad OcUK charged over £400 now. I limited myself to £400 and it looks like I've been spared a hassle and major disappointment. I hope all you guys get your problems fixed but I'm beginning to think these screens are so cheap because of poor quality components (glass not fitting, poor stands, etc) and being panels rejected by other companies (Dell) and thus sold cheaper because they weren't perfect.

From the statistics so far, I'm pretty confident that replacement is not going to help.

My thoughts are that ocuk and hazro have sold worse than class 2 (ISO 13406-2) screens to us. This wouldn't be an issue if the product description said something along the lines of "95% of these screens WILL have defects" or were marked as B-grade. What we were actually told was that these are comparable to apple cinema displays - which is not the case at all (trust me - I have one!).

My main issue is with the black spots all over the screen which I'm fairly sure is dirt. Whilst a few stuck subpixels is annoying it's not as bad as the dark 'scars'. With the iMacs and cinema displays, uou can remove the glass panel with some suction cups [see here]to remove the dirt - but I'm not sure how the glass is secured on these monitors.

this ones better lol

in case anyone missed it in the main HAzro thread, the manager from there has posted the following

Managers Post:

We are closely monitoring feedback so please share your experiences [both +VE and -VE] as feedback from customers is vital for future improvements.

Most of the 'spots' or 'dots' noticed are not defective pixels: its dust that has gathered behind the glass. Clean room operations minimizes build up but total elimination is impossible. Dust gathers on all panels but the combination of panel vibrancy and glare can make it more noticeable on these models [as well as closer customer scrutiny].

Dust accumulation was always a problem from the moment this monitor was conceived. We tried open front bezels but contrasts seemed washed and faded. Color tinging wasn't so much of a problem so a transparent filter would have sufficed. That was until we tried applying it - very difficult and time consuming. Glass was the only option. We had to choose glass which didn't compromise the viewing angles so we stuck with Asahi from Japan.

Encapsulating glass around an open beaded trim was another problem: this is evident from posts which comment on how the glass seems 'raised' in some corners. Glass uniformity across the horizontal plane [in theory] has a tolerance of +/- 1mm and human assembly adds another +/- 1mm. Adhesive which bonds the glass adds a final +/- 1mm.

Until now, we didn't have a 'general everyday use' monitor as most of our displays were industry orientated. A few consumer grade monitors we did have were snapped up by OEMs looking for '1 vendor only' licensing. We still have budget displays floating about in EMEA distribution channels under retailer specific brands. As a B2B company, launching these models into the consumer domain was always going to be a challenge but we're confident we can overcome any shortfalls to make a success of it. We feel for the price, the combination of aesthetics, resolution and panel quality cannot be matched.

We welcome your posts and look forward to hearing feedback.

I suspect a lot of these issues are in fact dust and not dead pixels. Fully dead (black/white) pixels are pretty rare nowadays. obviously if they show red/green/blue then they are dead sub-pixels and cannot be attributed to dust. With the volume being reported, especially in small clusters, they could well be dust particles trapped behind the glass. i've seen it before from other glass coated screens (anyone remember the old Xerox glass 19" screens?! )

someone posted a tip which helped them remove them by lightly flicking the glass to dislodge the dust. worth a try.

i suppose the question is, can these be noticed in practice anyway, or just when you look for them using a dead pixel program and all plain background? i expect if you used that program on most screens you would at first see dust on the surface (which you can obviously wipe off admitedly) but this isnt something you'd normally see in normal use

How much did Hazro bung you for your review?

i've have this problem with a xfx HD5870 screen would only turn on when the windows login screen appeared, i stuck in my old 8800GTX and it works perfectly.

Hi there

I've been having a look at the ones were using here, basically I've gone dust searching.

I've looked at three units, all appeared to be fine. But upon looking at this thread I've run dead pixel checkers or just changed the screen background to solid colours.

Upon doing this on two of the screen I can see minor dust particles when up very close to the monitor and looking for them.

Unfortunately this is a downfall of glass fronted panels, the last glass fronted panels I remember selling were some Xerox units many years ago which had exactly this issue but we were selling them into B2B type customers and as such it was never an issue as the advantages of a hard glass panel far outweigh the dis-advantages.

Had I known the Hazro's were glass fronted would I still have purchased them? Yes I would because the advantages of the glass panel and the price point of these monitors make it all worthwhile and in normal operation and a normal viewing distance of ten inch plus those particles cannot be seen.

I understand some may have issues with this which is understandable but I am going to be honest and I think the chances of getting a perfect screen thats completely dust free is quite minimal if I am honest, though I could be wrong and even if you get a perfect one in a years time it won't be as dust will find its way in. But the dust particles I've seen on the monitors here are not noticable until you actually look for them. I am in agreement with Hazro and Badass for the money the value is unbeatable.

I've got two dead subpixels and a few places where it's either dust or a group of multiple white subpixels (which are around the corners).

They can be noticed in practice, either when watching movies or working on specific backgrounds. Hard to notice when playing games when you've got quickly changing backgrounds.

I would love to keep the screen and have the dust under the glass removed but I'm afraid that's not possible without voiding warranty, is it?

I'm sitting two feet away from the screen and can certainly notice them especially on black backgrounds. There is also problem with other stuck subpixels that are in a few places on the monitor, I'm pretty sure I'm not an exception when it comes to these faults.

thats pretty rude isn't it? they didn't "bung" me anything for the review and i have only ever reported honestly about the screens i've reviewed.

Try to find me some dust on an imac or on a cinema display, you'll have a hard time! If you can find any (I've never seen any) then all you have to do is pop the glass cover off with a few suction cups to give it a wipe.

Why do iphones, ipads and ipods not have large spots on the screens?
Perhaps it's because they fuse the glass to the LCD display so there is no cavity?

The dust on my unit seems to be on the LCD panel itself so I can't get rid of them. Whilst dust may sound trivial to you, it looks very much like clusters of dead pixels!

Perhaps if you look at pictures or play games then this isn't an issue, but I work with white backgrounds all day (documents).

I'm not suggesting that the monitor isn't great, but it is let down by these issues which were avoidable.

Indeed my iMac is dust free with no pixel problems.

I regret buying the HZ27WC now, its now being returned due to dust problems. All that waiting for nothing. I should have just bought the ACD instead, yes it's more expensive but Apples quality control is far superior to Hazro.

 

[hlennie]

Has any one had the same sort of problems with the Hazro HZ27WA

 

[silverf0x]

Has any one had the same sort of problems with the Hazro HZ27WA

yes, I have. I also work on white backgrounds and it is annoyingly noticeable.

Is there any one who has had NO problems? Probably enjoying their monitors in peace.

 

[Combat Fighter]

I'd like to know how easy it is to remove the glass front so you wipe free the dust.

 

[Gibbo]

This would be a good option for sure as when dust develops you could wipe 99% of it away.

Shall forward thread to Hazro and hopefully we shall get more input from them.

 

[hlennie]

Hey Gibbo what percentage of the Hazro HZ27WC are seeing these problems

has the Hazro HZ27WA had the same amount of problems

 

[Reality|Bites]

maybe they could have installed a screen wipe thingy like a thin black board eraser that had a little handle on the outside you could move up and down. It would be hidden behind the bezel when not in use.

If we can clean the glass without voiding the warranty, there won't be many RMAs/DSRs, I guess.

They can't know that for sure, RMAs haven't started just yet and I'm sure they wouldn't disclose such information anyway.

Look through the threads and see for yourself - none of the posters seem to have problem-free panels.

+1, it's the dust that bothers me, not the dead subpixel!



FYI, it looks like RMA's will be refused.
I just had a webnote update:

WE can not accept this back as faulty i am afraid.
