Has anyone found a fix to the issues when using a HZ27WC + Nvidia graphics card yet?

I can't change any of the display settings in the nvidia control panel and i REALLY need to change the scaling options as it's starting to drive me crazy!

I've asked in the big hazro thread but i tihnk it might be handy to split this specific problem off from there, has anyone got an inf for the monitor or customised one themselves that works with it yet etc?

I've tried various nvidia drivers but nothing on that front seems to solve it.
 
As far as i'm aware, Hazro have no plans to release a inf windows driver for these new screens or fix the the problem at the hardware side.

I do think some of the problems are caused because windows and graphics card software is not recognizing the screens properly and the
fact that these screens don't work right on certain brands of graphics cards.

I wonder if they know about HDCP not even working and if they are planning on fixing that.

I sent mine back to OcUK for a refund for the same reasons as your problems that I experienced as well and the fact that HDCP does not work.

I've posted on the nvidia forums, yet to get a response though to see if they can do anything about it.

Can't find any contact details for hazro anywhere, completely impossible company to get a hold of :(
 
I don`t think it's a nvidia driver problem concerning scaling as I have heard others say that the software scaling in nvidia control panel at least is working fine for them.

I reckon in might be down to certain brands of graphics cards and could be due to certain computer configurations.
 
Have you tried to play around with different inf files? like u2711 or something. I know i did this way back in the days when i got problem finding exact the drivers i wanted.
 
I'm starting to think it is nvidias end that this is a problem, i've just edited an inf (albit i have absolutely NO IDEA what im doing, im just sort of playing on what i know to attempt to make it work) and it has made no difference, infact the inf seems to make no difference to the nvidia control panel seeing the monitor as a "Syncmaster" which is odd?

On the birght side my device manager now whos up under monitor as "Hazro H27WC Series Wide LED Monitor" and the manufacuer appears as Hazro :p lol as i copied and edited a HP 27" monitors inf and installed that.

Question now is where would i go to edit the nvidia control panel settings?

The fact the inf has made no difference at all is making me wonder if it's an nvidia driver issue?

I remember someone mentioning some luck using the HDMI output though, i've got a mini HDMI > HDMI cable and i've ordered a HDMI > DVI converter so i'll see how that goes on tuesday (bloody bank holidays, delivery men should work through them!!!!)

EDIT: I have now messaged nvidia via their bug report section, i've messaged hazro via their web form and ocuk are looking into the problem when they can get a chance to replicate it and hopefully contact hazro themselves. I think i've done all i can until i get some answers back now.

Guys I just made an inf file that overrides the broken EDID in my Hazro HZ27WC.

I now have Nvidia Scaling options, and my monitor appears as a "Hazro" not "SyncMaster".

This works in my copy of Windows 7 x64, I am using a single GTX 580. However, according to Microsoft's Dev Centre website, this technique should work for any version of:
Windows 7
Windows Server 2008
Windows Vista

I searched these forums for ages but didn't find the answer, so I found my own solution. I compared the EDID from the Apple Cinema Display 27" with Hazro's and noted that Apple's didn't have any "Standard Timings" in theirs. I then removed those entries from Hazro's EDID and changed the "SyncMaster" to "Hazro HZ27W Series" and everything worked as it should.

I can't be the only guy to fix this right?

So please let me know if any of you need this and I'll post it for you guys. You never know, it may work for you too? It certainly is a pleasure to have a fully working Hazro playing nicely with windows!

******* THIS SCALING FIX IS FOR THE HZ27WC, tested with Windows 7 or Vista ONLY *********
******* ALTHOUGH THIS IS A SOFTWARE FIX, PLEASE USE AT OWN RISK!!!! **********


My first recommendation would be for you to create your own inf files using my guide below. However, here is my own inf file for you guys to try on your own rigs. Remember windows will say that the monitor inf file is not digitally signed - that's because I made it for personal use. You can look through the inf file though in a text editor like notepad and see that there's nothing but the usual monitor timings stuff.

DOWNLOAD MY OWN WORKING INF FILE FOR HAZRO HZ27WC HERE

Perhaps it would be best to write a short guide as to what I did and then you guys can do the same, using your own monitor's EDID as a foundation for the alterations?

I read this page. This guide is essential reading. Don't attempt to do any of the following untill you's looked at it. If you read it, you'll have a working monitor and be wiser too!

I found the Apple Cinema Display 27" EDID and compared it to Hazro's which has similar functionality. In Apple's, the only big difference was that they had no "standard timings" entries. So I decided to copy my Hazros EDID and remove them like Apple did. This is how I did it...


1) I downloaded the tools as in the guide and grabbed my monitor's EDID readings from the registry in the tool called PHOENIX by looking under the tool menu (your monitor's entry should start with "HYO".

2) When this entry is loaded into PHOENIX it is in read only mode, so click on the tab called STANDARD TIMINGS and the pen to switch to EDIT MODE.

3) Now untick all of the STANDARD TIMINGS entries 1-4, then 5-8 by clicking on the wee dot at the bottom of same page. So that's 8 boxes to untick ok? The native resolution timings are held elsewhere in the EDID, and as there are no other supported resolutions for this monitor, these additional timings are useless.

4) I then SAVED my new EDID in PHOENIX as a "dat" file.

5) I then loaded this into the downloaded MONINFO tool, made sure it didn't complain about my file, and then immediately looked under FILE and chose CREATE INF.

6) Now we use this INF file to replace your monitors current driver. So to find the Device Manager, open Start, type devmgmt.msc and press Enter.

7) Select the monitor you want to change, right click and select Update Driver Software

8) Avoid the "Search automatically" option and instead chose "BROWSE MY COMPUTER FOR DRIVER SOFTWARE". Use the tried and true "Have Disk" method to select the included INF and install it, accepting any warnings.

9) Reboot. Scaling and resolution details should now appear correctly.

10) Hopefully your monitor will now behave as it should in windows, if not go to SAFE MODE and remove the fix under monitors by right-clicking and uninstalling.

BONUS
If you also want to change the name of the monitor from "SyncMaster" to Hazro, you can also do this in PHOENIX - just edit BLOCK 3 under DETAILED TIMINGS before saving your "dat" file. The new monitor name won't appear till after you've rebooted though.

That's fantastic, thank you colin :)

All i've ever wanted from this monitor was the ability to change the scaling from "aspect ratio" to "full screen" and i can finally do that.

What makes me laugh is Hazro couldn't give me an answer to this problem after numerous complaints (hell, most of the time they didn't bother to reply) yet you've done it yourself! :D

EDIT: All options now available in the nvidia control panel and monitor displays as "Hazro HZ27WC" in device manager, awesome :D

you should Email Hazro and inform them off this as this could save them a lot of effort and save a lot of people pain

But anyways Welcome and Nice one !! :D :D
 
HA that's Laughable a laughable idea, as if they're even bothering to try and fix it!

Sadly they're one of the most useless companies i have ever come across when it comes to things like this, just a lucky thing proactive people exist within our communities :)

True true but if there presented with afix to the problem which could save them some face and claim THEY have sorted it what company would pass on that ?
