Hazro series - HZ30Wi, HZ30WiQ, HZ27WA, HZ27WB & HZ27WC

I have a Mac Mini and a PC which I need a new monitor to hook up to. Atm I have a Dell that has a fairly quick process to switch displays.
Is there any chance you could give an idea of how input switching works? is it buried in the OSD (worst case) or can you use 1 button (best case) to switch inputs, specifically on the HZ27Wa

Cheers.
 
In reply to jpaul's questions:Paul

1. The HZ30Wi comes with a Dual-Link DVI cable which is backwards compatible. Even if a <WQXGA resolution is being fed, we still recommend using the supplied Dual Link DVI cable. A HDMI>DVI converter need not be labeled specifically as 'Dual Link'. However, if a HDMI>DVI 'cable' was to be used, then the cable would have to be Dual-Link. Your right about the manual, it should read: 'Never use a Single Link DVI Cable with a monitor which has a native resolution above WUXGA [1920x1200]' - I have asked for this to be changed.

2. In FULL SCREEN mode of media players, video will stretch horizontally the same for both Hazro 30" and 27" displays [2560 pixels] - although do remember that the pixel pitch is somewhat different on the 2 monitors. Vertically, the 'stretch' is less on the 27" at 1440px [as opposed to 1600]. Is it noticeable? I very much doubt anyone would notice a difference. I'm not aware of a media player which enters full screen mode and applies vertical borders. The alternative is to simply watch the video in its native recorded res which on such a large monitor, would always end up in a window.

Update: Some useful info from a post on page 2 of this thread by 'Duffman': From the nvidia / ATI control panel you can select how non-native 3D graphics are displayed (i.e. games). You can choose to extend the image to use the full screen ("normal" mode), or you can tell it not to do any upscaling (like "1:1 pixel mapping", resulting in horizontal and vertical black bars for sub-native resolutions).

The Hazro 30" and 27" displays feature single inputs only which is why multiple computers/devices cannot be connected. Therefore, there is no switching option. You can purchase a Dual Link DVI switcher but they're not cheap [+£200].
 
Hazro, thanks for the reply in #63
1. I think manual could just confirm that a dual link cable is required above wuxga
but a single link is adequate for lower resolutions eg 1080p
2. I had misundertsood that your explanations apply to full screen media players;
moreover my concern was what happens driving monitor with a typical
1080p laptop hdmi/single-link-dvi output;
you had already answered this question however and said - image is blown up.
I guess it is too late to get firmware adapted so image is not blown up and
would give 1:1 pixel map (black bars on all sides) no internal monitor scaler used,
this would be useful (or have an alternative firmware users could employ)
This is coincidentally acknowledged as a limitation with competitors product HP
zr24 where1080p images are blown up to its lower 1920x1200 screen
I suppose, in the absence of an OSD for user to make a selection, a choice had to be made.
Thanks, Paul
 
We're running behind schedule on these - Hopefully, we'll have most orders out this week [ending 12/11/10]

Another week has gone by, so I shall ask the question yet again...

Is there any word on when the first batch of HZ30Wi screens will be shipped out? Have any screens been shipped at all? I haven't heard of anyone receiving a screen yet...

...Are you still planning to honour all orders?!
 
Well, looks like Fed-Ex have dropped the ball...

I got a shipping confirmation and tracking number from Hazro - the screens were due for delivery today between 9am and 1pm, but they haven't arrived. Fed-Ex shipping shows that they have not even been loaded onto the van... I can't call them to ask about it, as they shut at 12 on Saturdays :rolleyes:

I hope this doesn't mean I have to wait until next Saturday now!
 
No news on this?

I've got a couple of HZ30Wi screens heading my way (were due on Saturday but didn't arrive due to Fed-Ex screwup, though I should have them by next weekend), and I will post a rundown of them when they arrive.

(2nd quote by Duff-Man from another thread)
30" model still overdue on main site. It's starting to look like the November launch date for the 27" models is optimistic. :(
 
My screens arrived today :) I haven't had a chance to set them up yet (been busy), but I'm done working now, so after I've eaten it's playtime :p Anyway, I'm guessing that others who ordered through OcUK will be getting their screens very soon...

Hazro despatched mine on Friday for Saturday delivery. I got a dispatch confirmation from both Hazro and the courier (FedEX) confirming this, but they didn't show up on Saturday (clearly the fault of Fed-ex and not Hazro). I also got a phone call from Hazro this afternoon checking that they had arrived, which was a nice touch...

Anyway, like I've said before, I'll give my thoughts on the screen once I've had a chance to put them through their paces.
 
Hi,

I'm wondering if you could let me know what the sync polarity of the HZ30Wi screens is? Also, is it possible to adjust this in software? I'm having trouble getting the screens to work in nvidia surround with my existing screen (zr30W), and I'm guessing this is what's causing the problem.

Both screens work fine by the way... I'm quite pleasantly surprised by the quality as well - they compare quite nicely to the more expensive HP zr30W I have, and they certainly look a lot more slick (full aluminium frame, thinner bezel etc). No dead pixels on either screen, and a good backlight uniformity... I'll post more detailed thoughts later, but so far I've just been pulling my hair out trying to get nvidia surround up and running!
 
Hi,

I'm wondering if you could let me know what the sync polarity of the HZ30Wi screens is?

Not sure what you mean by syn polarity but if its the vertical refresh rate, its usually just under 60Hz. In a dual display setup, if the refresh rate is out of sync [which is possible], you can download Powerstrip from here.

The vertical refresh rate can be dropped/increased slightly by 3 or 4 increments max. Hopefully this will help.

Thanks - I'll try out powerstrip tonight and see if it helps. It seems like it's a powerful tool...

As for sync polarity, well I'd never heard if it before yesterday, but Nvidia's requirements for a multi-screen 3D gaming setup state that "all screens must support a common resolution, refresh rate and sync polarity". Since all three screens support 60Hz and 2560*1600 or below, I figured the sync polarity was the issue. Apparently the sync polarity is either (+) or (-) for each of the horizontal and vertical components independently. As for what it does, I have no idea... Information on the web seems pretty sparse.
 
Completely unhelpful comment but crappy nVidia drivers? :)

Have you tried with an AMD Eyefinity capable card to see if it is that?

Could well be the drivers causing problems... I tried switching back to an earlier version, but that didn't help. Upon switching back, I now can't even change around the order of the screens in "normal" multi-monitor mode :confused: Time for driver cleaner I think. I have to say this is the first time for many years that I've felt like I was being let down by display drivers (ATI or nvidia).

I don't have an eyefinity card to test with I'm afraid... It would probably work, but I'm trying to drive three screens at 2560*1600, so a single GPU would not really cut it in anything but the oldest games, and unfortunately the performance of eyefinity is still a long way behind nvidia surround (even using two 2Gb 5870s performance is a good 35% behind what I have now, according to the HardOCP review).


I suppose as an alternative I could sell the zr30w and get a third Hazro... Probably wouldn't cost me too much to do that, but I'd prefer to keep the setup I have right now (plus I'd have to wait a few weeks for the new screen). Also, if the surround still didn't work I would be fuming :p
