Asus PA328Q ProArt 32-inch UHD Monitor Review

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Grayscale Tracking & Gamma Response

Our grayscale and gamma tests are described in detail here.

The PA328Q arrived at our lab in its Standard mode. As you can see there are no visible grayscale errors and calibration really isn’t necessary. In this mode you can alter the color temp via presets but if you want access to the gain and offset sliders you’ll have to switch to User.

sRGB mode looks almost exactly the same as Standard. Again there is no need for adjustment which is good because no adjustments are available except hue which provides no benefit.

If you must tweak as we do, the User mode yields even better grayscale tracking. You won’t be able to see a difference with the naked eye but if want every possible ounce of performance from the PA328Q, calibration is the way to do that.

Here is our comparison group.

1.42dE represents the Standard mode. Asus claims errors of less than two Delta E and our sample achieves that with room to spare. In the sRGB mode we measured 1.52dE which is only a tiny bit higher. Either way the PA328Q meets its advertised performance handily.

Our calibration turned excellent performance into slightly more excellent performance. This improvement does more to satisfy ego than anything else.

Gamma Response

Regardless of picture mode, gamma tracks to near-perfection. You can change the preset to 1.8 or 2.4 from the default of 2.2. In both cases tracking stays flat as it should. Since we’re picking nits here we do wish there were a BT.1886 option for those editing film and video content.

Here is our comparison group again.

A .08 deviation in values is almost nothing and that dip happens mainly at the 90-percent brightness level. Gamma tracking doesn’t get much better than this.

We calculate gamma deviation by simply expressing the difference from 2.2 as a percentage.

The average value is 2.15 which represents a 2.27-percent variation from the 2.2 spec. Again this is such a tiny amount it’s barely worth reporting.

    Oh my. I'd use this one as a nice digital picture frame. Not gaming because 1080p 144hz gets you much less lag, persistence blur and stutter. These resolutions are really too high for decent gaming.

    This isn't a gaming monitor. It inst very high priced for a professional grade 32 inch monitor with 100% sRGB.

    i use pro-arts as gaming monitors.. the PA 248Q is what i roll with

    I would have seriously considered this monitor for gaming and creative work, but the lack of adobe RGB on a $1300 monitor kills the deal.

    This is a special use monitor for sure.. I bet it would be nice for 4K video playback..
  • Trusty644
    I think LG31MU is a better fit for the price. 100% sRGB and 99% Abobe RGB

    If you're going to review a PA Professional grade monitor whose advertizing and promotional claims touts 100% Adobe RGB I would think you would have underscored the fact that it only achieves sRGB as a major issue. Instead you've glossed over it and reviewed the monitor as though such claims were never made and or never existed. Doesn't it say on the box 100% Adobe RGB? And yet nothing about it is mentioned. Not much of a review then is it.,29225.html

    What's all the fuss about 100% coverage of adobe RGB?

    "If you need a 32-inch UHD monitor with a wide gamut only the NEC PA322UHD and the Dell UP3214Q have it."... and they cost twice as much.

    Can you find a 32" 4K monitor for less money that covers more? No. OK then what's your criticism?
