Interesting opinion.
I see in your signature that you have experience with both the Dell and the Hazro 30-inchers. Would you say the lower cost Hazro 30-inch is similar in display quality to the Dell 30-inch? Are the anti-glare coatings different or similar?
The standard Hazro (the type I use) uses a Q3 LG panel, not a Q5 like the more expensive HZ30Wi-Q or Dell U3011. However, comparing the two, the Hazro has a more noticeable sparkle effect and colour push than the Dell screen. The Dell pushes red so whites look pinkish but to a lesser extent (IMO) than the Hazro [Q3 panel] pushes to green. Due to the more aggressive AG coating on the (again, standard) HZ30Wi allows me to guide you in the direction of the Dell for overall display quality. The backlighting of the Hazro seems to be more noticeable in a way too, in that the black level is not quite as deep as one might like it to be.
You get what you pay for. The standard HZ30Wi is still a fine monitor pending you can live with a few potentially stuck or dead subpixels/pixels. Ultimately there is a simple reason why I chose the Hazros as flanking screens to the Dell I initially bought: 1. 2 x U3011 = £2400. 2. 2 x HZ30Wi = ~£1700
My point is that Hazro made the aluminium cased screens first for industrial use, that is more close to their business plan than a more consumer-oriented model. In other words, let the company make what they make best and give them time to adapt to manufacturing more consumer-oriented models.
