BenQ BL3201PT 32-inch Ultra HD 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.

Results: Grayscale Tracking And Gamma Response

Our grayscale and gamma tests are described in detail here.

To the naked eye, there aren’t any grayscale errors in Standard mode. The chart shows a maximum DeltaE of 3.22 at 50-percent brightness. That’s only a tad over the accepted threshold of three, where grayscale errors become visible. If you don’t wish to calibrate the BL3201PT, you’ll be perfectly satisfied with its grayscale accuracy.

Calibrating the User mode yields a decent improvement in grayscale performance. To get 100 percent under the 3dE line, we lowered the Contrast four clicks to remove a visible green tint. Otherwise, BenQ's business-class monitor delivers excellent performance.

Here is our comparison group:

A result of 2.25dE is perfectly acceptable for an un-calibrated monitor. A majority of users will enjoy the BL3201PT’s image quality by simply adjusting brightness to taste in the Standard mode.

Calibration brings the average error down to 1.38dE. That's not quite as low as the rest of the group, but you won’t be able to see a difference between any of these screens without instrumented measurements. The BL3201PT doesn't perform in what we'd consider the professional class, but it's not priced like those premium products either.

Gamma Response

The most accurate gamma tracking is found on the number-three preset. Whether you calibrate or not, this is the tracking you’ll see. Our adjustments didn’t make a difference. Aside from the tiniest dip at 10 percent, we record a perfect result.

Here is our comparison group again:

The .15 number comes from the above-mentioned dip in gamma at the 10-percent brightness level. All other values are within a whisker of 2.2.

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

This is only the third monitor we’ve measured in the past two years displaying a perfect average gamma result of 2.2. It doesn’t get any better. Gamma this accurate easily makes up for lower contrast by providing maximum punch in all types of content.

    I wouldn't want to bump it over and drop it from the table, because the stand looks so tipsy.

    I wonder why all the links to Amazon belong to the BL3201PH not the reviewed "PT" model. Am I missing something?

    I Don't Know Why monitor vendors can't make a decent 28 inch IPS UHD monitor below 500 $ whereas I bought my LG UB820T 42 inch IPS 120 Hz UHD TV for only 630$ ,and it comes with the amazing magic remote and TV tuner and smart TV support, WIFI and LAN , USB 3 and 3 HDMI 2.0 ports!

    Dell P2415Q and P2715Q are 4K 60HZ IPS panels which can be found for around 600$ on amazon.

    Why is everybody stating about Luminance / Brightness as "higher is better ". I had an Iiyama 27" IPS pannel that had over 350 cd you can`t even use that monitor at 100% brightness, you can actually feel the heat from the monitor on your face. Best use was at around 25 to 50% brightness ...had to return it though due to flickering .. my eyes were going insane with that monitor.

    I hate to ask, but how is the glow?

    The stand is sturdy since the 3200PT(2560 x 1440 MVA) was very solid with the same stand.

    I think the brighter is better has carried over from cell phone reviews or something. Working in a very bright area could also benefit from extra brightness. On the plus side almost all BenQ screens use voltage based dimming and not PWM. This should allow you to get a dimmer screen without the flickering(not that it bothers me).

    I personally have my screens at a much lower setting as well.

    Siiiick! This is the first 4K screen I've seen that seems reasonable in terms of price, performance, size, and image quality.

    "it’s selling on the street for under $1000." I wonder if they sell these on my street. I need to call and ask.

    I thought we'd start seeing some sort of adaptive sync technology on just about every monitor by now. I can't get excited about anything that doesn't have it.
