Hello. AOC G2460PQU have PWM?
The official website says about Flicker Free. http://aoc-europe.com/en/products/g2460pqu
And in the reviews write about PWM. https://pcmonitors.info/reviews/aoc-g2460pqu/

PWM is only used for Ultra Low Motion Blur (ULMB). If you're not using that, then it's Direct Current (flicker-free).

AOC G2460PQU does not have motion blur.

If it is using Ultra Low Motion Blur (ULMB) in order to achieve no motion blur, then it is using PWM because ULMB is achieved with PWM which flickers the monitor so that motion blur is reduced or elimintated. When you are *NOT* using ULMB, you are NOT using PWM which means you're using DC (Direct Current). Direct Current results in no flicker.

 

A monitor can be advertised as being flicker-free even if the monitor also has the ULMB mode that you can use if you wish.

 

I didn't look deep into this monitor's details, but I would bet you anything that it's using Ultra Low Motion Blur to give them the ability to advertise this monitor as having no motion blur, and since it's a mode that you can switch to, they can also say it's flicker-free because the other mode is using Direct Current. It's tricky and clever marketing. Most people who are sensitive to flickering absolutely *hate* ULMB.

 

If we look at the review done by pcmonitors.info published on July 27th 2013, they say that it only uses PWM; it doesn't have any flicker-free modes. However, when we look at the most current product page on AOC's website for this, they are saying it has a flicker-free mode (DC, Direct Current). So, it's my best guess that AOC updated this model and now the newest ones have an optional mode that results in no flicker. That would turn *OFF* PWM and use Direct Current which would result in *some* motion blur.

While the G2460PQU is new to gamers in the U.S., it’s been available abroad for several months. Comparisons to the Asus and BenQ 144 Hz displays are inevitable. The base specs are nearly identical. But there is one feature AOC doesn’t offer, and that’s any sort of motion blur reduction.
We talked quite a bit about BenQ’s Blur Reduction, which strobes the backlight between frames and can help reduce or eliminate motion blur at the expense of light output. Asus’ VG248QE does the same thing if you connect it to an Nvidia LightBoost-enabled graphics board. AOC, however, does not offer a comparable capability. Is this a potential deal-breaker? We’ll go into more depth about the implications on page nine, after our response and lag tests.
Aside from that one omission, the G2460PQU's specs suggest that it's a well-made gaming-oriented screen with the sort of performance attributes discerning enthusiasts are looking for. Let's see if those figures bear out in practice.

Yes, you put that in your original post. I saw it already.

 

Let's analyze each page closely though using CTRL+F for the following words: "motion", "blur", "reduction, "PWM", "pulse", "width", "modulation", "DC", "direct", "current. Here's what we find:

They are saying that this monitor DOESN'T have any kind of blur reduction whatsoever.

Overdrive can reduce the ghosting that sometimes occurs behind fast moving objects on-screen. When you’re running at high refresh rates, it won’t make a difference since motion blur is already negligible.

 

Most gamers hate using the 1ms response time of any monitor though because you get black trails on bright objects such as lights (and other unwanted problems). Yes, it's smoother, but at an unpleasant cost if you're sensitive to this. I have the AOC G2460PG and at 144 Hz with the 1ms response time set, I definitely get smoother motion but at the cost of the trails. So, I don't use the 1ms response time.

The G2460PQU is the brightest monitor we’ve seen in a while. In fact, only Planar's PXL2790MW measures higher in our tests. It’s a shame there’s no backlight strobing feature available, because the extra output would likely combine to provide blur reduction and decent brightness.

 

This means, no motion blur reduction. It means this monitor is now using the Direct Current (flicker-free) technology. AOC is known to change their monitors without notice like this. They did the same thing to mine. When the AOC G2460PG hit the market, it was loaded with features in the OSD menu like Crosshairs, Saturation, Blue Light reduction, refresh rate overclocking, etc. etc. etc. Today it's just a very over-simplified 144 Hz 1080p G-SYNC monitor that still has ULMB. Fortunately, I don't care for all those extra features.

 

Anyway, moving on:

 

Page 9:

 

Quote:
The G2460PQU becomes our new response champion with an extremely low time of five milliseconds. We really wish this display had a blur reduction feature because its panel response speed could certainly take advantage of it. Its extreme light output would easily counter the 50-60 percent drop in brightness caused by backlight strobing.

 

And further down the page...

Blur Reduction: Is It Missed?

 

I mentioned at the beginning of the article that AOC doesn't implement any sort of blur reduction feature. After running through several of the Blur Busters tests, I can say that it is not sorely missed. When the refresh rate is maxed at 144 Hz, motion is quite smooth and resolution in the most detailed images stays solid at fairly high motion rates. Would backlight strobing make it better? Yes, but only a little.

 

Yes, that's my experience too. I don't need ULMB. ULMB is stupid, it flickers the panel, and it reduces the overall brightness.

 

Page 10:

Now that the results are in, we can revisit our 144 Hz gaming monitor comparison. AOC becomes the new champ in our screen draw and input lag tests. It also comes close to matching the VG248QE’s prodigious light output. The biggest concession AOC's G2460PQU makes is a lack of blur reduction functionality, which Asus and BenQ do offer. 

 

I guarantee you that you will have *SOME* blur, but you won't care about it. This monitor is almost the same as mine if I were to disable G-SYNC and avoid ULMB. It's just a nice 144 Hz monitor, nothing more. It's nothing fancy.

 

 

As you can see though if you read that Tom's Hardware review, there is absolutely no motion-blur reduction of any kind. The only reason its blur is quite tolerable is it has a high refresh rate. If I were you though, then I would skip this old monitor and get the G2460PF or the G2460PG, depending on if you have an AMD GPU or an NVIDIA GPU.
