Hazro - Any Update?

Found a new problem with the 26Wi today.

Lots and lots of yellow lines flickering and dancing across the screen but the weird thing is it only happens when running Outlook Web Access under Remote Desktop. (not tried OWA on the same machine, IE is only used for WindowsUpdate on that)

I took a screengrab of Remote Desktop and pasted it into GIMP and it doesn't do it there.
Edit: It's actually stopped altogether after being on powersave for 10 minutes

Weird.

That 30" black looks mighty fine at that pre-order price.. Why is it so cheap? :S All the other 30"ers are loads more.

we were worried about the 30's too before getting them and asked if all these probs would affect the 30's - Hazro confirmed the 30's are a trouble free monitor free from banding/noise issues. I wasnt aware they were available from any reseller. What bugs me is that they seemed to be offered lower than what we paid! maybe Xmas come too late for us. nice screens though
 
I've been doing a bit of reading about DVI, apologies if this information has already been covered in the thread, I've read most of it but it is 79 pages after all!

Anyway, have a look at the "Reduced Blanking" section of this page http://www.playtool.com/pages/dvicompat/dvi.html

Basically using standard timings there is a fairly large gap in between frames sent down the cable, for 1920x1200 this pushes the pixel clock rate up to 193MHz which is a problem because single-link DVI is only good for 165MHz and even if Hazro shipped it with some magical cable made out of fairy dust that can run the higher rate without issue, the scalers they're using may well not be up to it. In any case the cable probably isn't made out of fairy dust and is likely to experience noise or corruption due to being run faster than it's designed for.

Reduced Blanking removes most of the gap in between frames (there's not really much call for it unless you have a CRT) this drops the pixel clock to just 153MHz for 1920x1200 back within spec for single link DVI and should be a bit kinder to the scaler.

It seems ATI do not enable this by default, but the way to do it is Catalyst Control Centre -> Digital Panel -> Attributes -> Reduce DVI frequency on high-resolution displays. For nVidia you have to change the timing standard to CVT-RB.

(un)fortunately I only occasionally have the problems with blue/yellow lines so I have no idea if this option fixes it, it's certainly working OK for me at the moment.

Perhaps someone who is badly affected could try this and report back?

Edit: After further reading it seems, ironically, that ATI have the better DVI implementation. nVidia know their implementation is poor so they enable reduced blanking by default.

Thanks for that very well explained analysis! What you explained gives me a few more options to try to get rid of the green snow effect. However it should be noted that the construction of the screen (such as extra shielding), the quality of the cable, and the quality of the power output all play a roll. Still, big kudos to you!

You are absolutely correct, of course, however my point is that without reduced blanking enabled, ATI would be putting out a signal that is out of spec and you can't really blame Hazro for producing a device that exhibits strange behaviour when driven out of spec.

I could have course be completely wrong on this, ATI should really be using reduced blanking by default on a single-link 1920x1200 display and it would worry me a bit if they weren't. Then again ATI always did have a bit of a reputation for iffy drivers, so I wouldn't actually be surprised ;)

Another interesting point that article raises is that a lot of cards use the DVI transceiver on the GPU for one of the DVI ports and an external chip from the likes of Silicon Image to do the second port. The SiL chip is usually higher quality and puts out a cleaner signal, so chances are that when driven out of spec the signal from that chip is less likely to be altered by interference and thus the Hazro is less likely to display the interference. This explains why swapping DVI ports works for some people. Of course better shielding on the Hazro also reduces the likelihood of interference being picked up.

It would also explain why the PS3 has issues. Sony (and console manufacturers generally) do have a tendency to cut corners on their hardware since consoles are usually sold at a loss so it wouldn't surprise me if Sony are using crappy HDMI transceivers. Does anyone here have a Hazro, a PS3 and an AV Receiver that supports HDMI? If so does connecting the PS3 to the Hazro via the receiver make a difference compared to connecting the PS3 directly to the Hazro?

PS. Dear Hazro, please can I have my firmware update, or at least a response to my email?
 
I am a little worried about Hazro, being a small company, and their customer service (response time). How have they been with those who have returned/exchanged/updated their screens?

I think with the lottery of screen buying, people swing to the likes of Dell.
 
You realise Dell's support isn't much better than Hazros though, right?

With Hazro you have trouble getting through to them. With Dell you'll get through to someone but they'll be completely useless.

I'm sure plenty of people can post their own Dell horror stories, but my favourite one is a guy who had a 2405FPW or something like that, one of the high-end IPS panels with lots of inputs. He was a student so used it for TV, PC, XBox, DVD etc. etc. When it failed, Dell replaced it with a newer model, same size, but it was a TN panel and didn't have enough inputs for all his kit. He spent months dealing with the idiots in their offshore call centre who wouldn't help since the replacement monitor wasn't actually faulty before giving in and buying some sort of switch box.

There's plenty more Dell horror stories in this thread if you don't believe me. (Warning: Contains strong language)

I'd probably change my mind if I'd been sat with a dead monitor for the last 6 weeks but for the firmware issue, I'm happier knowing that when I eventually get to speak to someone, I'll be speaking to someone friendly and competent, not some minimum wage idiot half way across the world who is reading from a script and cannot help if your problem isn't covered in the script.

I just hope Hazro aren't about to go under with the cost of all these upgrades. Personally I'd be quite happy to take the monitor to Birmingham myself, I drive past the place enough times!
 
I think that's the thing most people complaining about lack of contact are misunderstanding, with hazro every time myself or others that have dealt with them have had contact from them it has always been from someone at hazro in a position to get things done, take feedback and provide a solution. Not someone logging a case over the phone then passing it to another team.

I suppose what I'm saying is that when speaking to hazro about an issue you are speaking "with" them, not having your case logged by one person who usually doesn't know how to fix anything and which is then passed to another team which is then passed to RnD or whoever etc.

Since this thread I'm guessing they've seen a pretty huge boom in communication from people wanting to find out more and so on. Hang in there, it might take a bit longer but it will be done properly! :)

They started out as medical displays and displays for pro environments didn't they, if the consumer range doesn't kick off due to the current economy then if anything I'm sure they'll default back to their specific area and just continue to support existing warranty periods for the consumers. That's an if!
 
Yeah Lum, you're right. I just went through a Dell nightmare returning two 2408's. I don't want to deal with those idiots anymore. But at the same time I dont want to see a small company die within your warranty time or something like that.

I love the Hazro design, reminds me of ACDs, but desperately needs height/rotate feature. I wish them all the success, its companies like Hazro that push the envelope and love what they do.

BTW: is there no ETA on the black Hazro at OC, if not, then where else could I get the black 24"?

Just posting an update regarding my DOA power supply on my HZ24Wi. OCUK was quick to send a replacement and it finally arrived today. I've only had the monitor up and running for a few hours now but am absolutely floored by the quality and clarity. I use dual 30" ACD's at work so I was hoping I wasn't too spoiled, but colors on the hazro easily look more vibrant and text is slightly crisper as well. No green snow to speak of yet (I'm running on HDMI), and no sign of gradient banding (tested in photoshop). I'm very happy with this monitor!
 
Good to hear mate!

Next step is colour calibration to get the absolute best out of it! especially over the new few months as the panel settles into optimum running!
 
Hello, mrk

Sorry if this has been asked before, but what is the best hardware calibration device and software combined for Hazro screens?:o

Thank you for responding;)
 
Hi All,
Well i finally had a response from hazro, saying the banding is fixed with the firmware update! and they will get an engineer to call me before i send the display back to discuss "the various fixes for the snow!" so i will pack her up monday and get fill in the online RMA then! hopefully a fix is on its way!
How long have people usually been without a display once sent back to hazro!?
Ben
 
I waited 2 days for mine if I remember right!

Sylver, I don't think there's a "best" so to speak but the EyeOne display2 with BlueEye Pro software suite is regarded to be most popular because of the accuracy and reporting it gives (see my screenshot few posts ago showing an example).

Hope that helps!

mrk

Do you know of a uk online site that has the EyeOne display2 with BlueEye Pro suite for sale? You can contact me by using OcUK trust option if you can help with this.
