Brightness And Contrast

Uncalibrated – Maximum Backlight Level

Today's comparison group is a battle royale between VA and IPS. On the IPS side we have Asus' PA328Q Ultra HD pro screen; the NEC PA322UHD, also a professional product; and the BenQ BL3201PT, a value-priced UHD display. VA is represented by the Philips BDM4065UC and BenQ's excellent BL3200PT monitor, which uses the same QHD panel part as today's review subject.

Even though BenQ and Asus are using the same panel part, the PB328Q is quite a bit brighter in its maximum output. The manufacturer's claim is 300cd/m2 but that is greatly exceeded here. If you have to use your computer in a brightly-lit room, this 32-inch jumbo screen will still look vivid and saturated.

You can see that VA black levels are not just a little lower than IPS—they're less than half in our tests. The Philips is not likely to be beaten any time soon but the Asus and BenQ screens are running neck and neck.

The difference in contrast between the BenQ and Asus VA panels is due to their maximum output levels. Asus gets more light from the PB328Q. This should demonstrate that plenty of unique developments go into each product irrespective of the parts used. One should not assume identical performance just because base components are the same.

Uncalibrated – Minimum Backlight Level

The PB328Q has a near-ideal minimum brightness of 56.9712cd/m2. Only the Philips and NEC screens go significantly lower. We're glad to see that both BenQ and Asus paid some attention to this detail. There really isn't much reason to set your monitor to only 20cd/m2, it's just too dark for practical use.

The BDM4065UC is in a class by itself when it comes to black levels, but the PB328Q is clearly the best of the rest. Deep blacks like this are not found on typical IPS or TN displays.

Minimum contrast is just slightly lower than the max value; too slight to be visible in fact. Regardless of the backlight setting, the PB328Q maintains consistent image depth.

After Calibration to 200cd/m2

Thanks to the fine resolution of the white balance sliders, and the fact that they start centered in their ranges, black levels and contrast are unaffected by calibration. You can enjoy the PB328Q without adjustment but there's no penalty for dialing in color and grayscale to perfection.

We've measured plenty of HDTVs that can't match the native contrast of this big Asus. Along with the Philips 40-inch, this monitor is likely to remain at the top of the heap for the foreseeable future. We'll only see a significant improvement in monitor contrast when OLED hits the desktop. This is about as good as an LCD display gets.

ANSI Contrast Ratio

Thanks to superb screen uniformity, the PB328Q posts an ANSI result almost equal to its sequential one. The BL3200PT isn't too far behind so it's clear this is a very high-quality panel part. That it comes at such a low price is just icing on the cake.

    I would love if we could get some insider information about Asus' quality control issues. We can't all get press samples.
  • Poozle
    I would get it but... ASUS has so many quality control issues. Never buying their products until they fix that.

    Good thing it doesn't have Freesync, or I'd be seriously tempted to pick this up and move my MG279Q to the secondary PC...

    $469 at Newegg!

    ^^ SHHHHHHHH! I'm still trying to decide if I should get it or not. :)

    Why VGA port on such a product ? At this point a monitor like this should have DP 1.3 and HDMI 2.0 only.. since these are the future from what it seems.

    As a gamer and video editor i really want a monitor that can combine both worlds but for now it seems you have to choose, get high refresh rates but TN panels or good IPS / VA with low refresh rates.

    I'm still waiting for a UHD display with 120Hz/144Hz refresh rate, 10bit color (1.07b colors), 100% AdobeRGB coverage, 85%+ rec2020 coverage. Am I too unrealistic?
  • JonDol
    Yeah, I'm waiting for that too. With G-Sync or FreeSync and the latest HDMI (2.0 ?) and DP (1.3 ?).

    I went from a 22 inch monitor to a 32 inch TV..........amazing improvement is overall enjoyment of PC, Gaming and all that. Later went from a TV to a 34 inch, 1440P monitor.............even better. Size matters, it improves the overall experience tremendously.

    Out of *6* PB328Qs I tried, ALL had multiple dead pixels. I'm not alone -- see Amazon reviews. Strongly recommend choosing the BenQ BL3200PT over this Asus. (It uses the same VA panel.)

    I got a 4K (3840x2160) "perfect pixel" AVMA 10=bit 4:4:4 chroma 39.5" from korea for $580 last July. I should note, the back-light on the edges are slightly off and the new versions of that monitor don't have that issue.

    I am making a plea : Can you PLEASE start reviewing the anti-glare coating on monitors. Many monitors still have an anti-glare coating that gives an annoying shimmering effect and gives the impression that you are looking through something when looking at objects on the monitor. On monitors that don't do that, objects on the display look like they can be touched directly.

    You need to do this. Please. The stores around me don't have many monitors on display so I can't go look for myself what they look like prior to purchasing on the Internet. So I'm pretty much relying on online reviews to do this but no one ever mentions anything and anti-glare coatings.
