Brightness Uniformity



In addition to the performance at center, we’ve also added 9-point testing for brightness, both white and black. This is done the same way we measure color uniformity, except we only care about measured intensity. We set the monitor through the "OSD controls" to near 200 nits, and then measure those 9 points.

White Level Uniformity


 

Black Level Uniformity


 

Our plots here do exaggerate differences - the ZR30w is remarkably uniform with an average brightness of 203 nits and a standard deviation of 6 nits. There’s a bit of a pattern for white, up top there’s a measured falloff compared to the rest of the panel, but visually I couldn’t discern any difference. It seems that under 10 nits is difficult to really discern.

Blacks are a similar story - they're very uniform. The average is 0.31 nits with a standard deviation of 0.019. There’s a slight brightness difference horizontally across the display, but again even after intense scrutiny I couldn’t discern anything. Brightness uniformity is impressive as expected.

    Will this connect directly to a Macbook pro with a mini displayport -> displayport cable?

    I've been able to connect a MBP to other displayport monitors, and would like to know whether you can drive a dual-link display this way.

    I spent a greater part of today searching around town for a miniDP to DP adapter, but couldn't find that nor the cables. I'm under the impression that it will work, and might even pass the 10-bit deep color data too. I'm hopefully getting an adapter soon.

    Cheers,

    I have a Dell 3008WFP that I've connected to my late 2009 Macbook Pro with a mini-Displayport to Displayport cable using this cable:

    It works perfectly and avoids the issues with the overpriced Apple mini-DP to dual link DVI adapter.

    Hey, just letting you know that the ZR30w does work driven from the 2010 MBP over a mini Display Port to Display Port cable. Flawlessly, really. No problems at all thus far!

    Cheers,

    Hey Brian,

    I realize this is a few years late, but I am trying to make this work with a mid 2010 15" MBP and having no luck. Did you have to do anything other than plug it in?

    Thanks!

    Nine bucks for a G520!?!??!

    Screw LCDs :-D

    So... what's the refresh rate? 60 Hz? 75 Hz? 120 Hz? 240 Hz? I didn't see the refresh rate on the table of specifications, and that would be something worth knowing for people in the market for a high res 3D display.
  • Brian Klug - Tuesday, June 1, 2010 - link

    The refresh rate over DVI is still 60 Hz, at least as reported in the display manager.

    Cheers,

    60Hz, it's always 60Hz for computer monitor using IPS or PVA panels.. well today... it might change later.
  • Bolas - Tuesday, June 1, 2010 - link

    I figured it was 60 Hz, but you'd think that they would spell that out in the specs. Pity it doesn't have pivot feature, but whatever.
