Dear Overclockers,
I have been having trouble calibrating my shiny new Hazro HZ27WD (and it is certainly shiny indeed! Despite being the non-glass version, it has a far shiner panel than I'm used to. I certainly can see myself in it). Oh for reference, zero dead pixels, one stuck red pixel middle right. I'd have DSRed it back if it were green or white, but red, well red or blue I can live with, especially at this tiny dot pitch. You really barely notice it, even in movies.
One might think, logically, that the HZ27WD is merely a HZ27WA with added DisplayPort. After all, the panel is the same, the casing is the same, the OSD is the same, the W-LED backlight is the same and so on. One might therefore think that the settings found by TFTCentral would be very similar: http://www.tftcentral.co.uk/reviews/hazro_hz27wa.htm
In short, this review suggests the following settings:
Brightness 10
Contrast 100
Color Temp User
RGB 30, 17, 25
ECO Mode 25
Supposedly the WZ27WD is calibrated at the factory. Well if it is, either my eyes suffer from seeing everything in shades of blue or their "calibrated" colour temperature is way, way too high. The TFTCentral settings are MUCH better, but they suffer from four problems:
Just to be clear, you CAN get excellent picture quality with no problems. It's just I'm not self confident in what I'm choosing, so I keep resetting and fiddling. I'd like some peace of mind!
So, can anyone help me with some suggested settings for the Hazro HZ27WD specifically? Settings where the Lagom tests all pass and gamma @ 48% is 2.2 like it's supposed to be.
I'm not crazy about getting colour perfect, but getting it reasonably close is important on a €600 monitor
BTW I'm using DisplayPort, and yes I get the same problem as others have had with an occasional timing problem with the signal from a Radeon 5770 causing display glitches.
Other thoughts on the Hazro HZ27WD: For such a jump in price, I'm still not sure if the extra resolution beats a high quality, IPS 1920x1200. However, I thought that about my old 1920x1200 monitor until I became used to it, then I found I couldn't use anything smaller. So maybe it'll grow on me.
I will say that the colour range is excellent even compared to the VA panel I had before. Colours are more saturated, transitions more even, and ICC profiles have a much greater effect on what you see than they did on the VA panel. Just goes to show what an 8 bit panel can deliver over a 6 bit panel. I have my old monitor next to my new monitor, and it's simply amazing the difference when showing a picture. That may well grow on me too.
Build quality wise, well it ain't great. I particularly think that the power adapter is extremely likely to die sooner rather than later. It seems to like making a loud click noise as it cuts out from time to time and the monitor flickers. OTOH, it's an external brick, so is easily replaced.
Oh, one other thing: the HZ27WD comes with a 1m DisplayPort cable. Yes, one metre. In other words, totally useless except for testing that the monitor work.s You can find a 1.8m or much, much longer cable on eBay for £5-10 inc. delivery. I'd actually support such a bargain basement monitor having no bundled cables apart from power at all personally. It's not like enthusiasts don't already have bags stuffed with cables (me, I have three so far)
Thanks in advance,
Niall

- The picture is too dark. No, I really mean far too dark. Even on ECO 100 the lagom test (http://www.lagom.nl/lcd-test/) fails to show the bottom two shades.
- The contrast is too high. It blows out the top two shades of colour according to http://www.lagom.nl/lcd-test/. I have to drop contrast to about 70 and brightness up to about 35-40 to get the colours to have an even progression.
- Without fixing either of the above, gamma is way too low hitting about 1.8 on 48% luminance according to http://www.lagom.nl/lcd-test/. After fixing the above luminosity and contrast problems, I get gamma going too high hitting about 2.5 on 48% luminance.
- Even after the above, pictures are too yellowy and white's colour temperature still looks over 7000k (how too blue can combine with too yellow I don't know). Flesh tones in particular make everyone look like they have cholera. Now you can twiddle with these to make flesh tones look right, and of course you can drop the blue to get white looking like a sheet of paper under daylight, but to be honest at this stage we're getting far away from the settings by TFTCentral.
Just to be clear, you CAN get excellent picture quality with no problems. It's just I'm not self confident in what I'm choosing, so I keep resetting and fiddling. I'd like some peace of mind!
