Asus ROG PG248Q 24-inch 180Hz G-Sync Gaming Monitor Review

Not open for further replies.

Uh, another con that is NOT listed: lack of FreeSync. Why? G-Sync already excludes AMD cards (and while it is considerably less important to most of us, Intel iGPUs too.) With FreeSync not having the NVidia G-Sync "tax"... oh wait... NVidia might contractually exclude the possibility of any monitor that include FreeSync and/or older adaptive-sync technologies in addition to G-Sync.
1. Both Asus and Acer have always offered both G-Sync and Freesync versions of their Gaming monitors. The only impact on the consumer is the effort choosing the one that matches their card. No real mystery that the nVidia version hits the market 1st given the image below. Not really a mystery when vendors concentrate on the 82% of market before addressing the 18% of market.

2. Either way, 144, 165, 180 Hz provides technology that represents the upper cost niches as opposed tot he lower. Peeps purchasing monitors at the upper price limits in any given category are likely to be purchasing GFX cards in the upper price limits. So what we see when pepes post their builds for the most part is GTX 1060s / RX 470s paired with $250 monitors. With 1070 / 1080s in the build, the monitor budget is a bit higher.

3. It may be fun to call the price difference a "tax" but that is a misnomer:

AMD Freesync package provides Freesysnc and no hardware module is installed in the monitor.
nVidia G-Sync provides G-Syn and also includes a hardware module for ULMB

When two monitors are made using the same panel, and electronics ... then one has a hardware module installed which provides ULMB and the other does not, is it not logical that that hardware module has a cost associated with it ? You can buy Freesync monitors with motion blur technology included but in such cases it is added by the monitor manufacturer. The difference being that w/ G-Sync, it's always the same module... with Freesync, the design and quality varies by monitor manufacturer.

Never quite understood the mindset where there's an expectation that a company should invest millions of dollars in R&D and then should be required to share that technology for free. AMD has had the opportunity to license technology in the past and chose not to.

4. As it says in this review:

"While FreeSync offers the same net benefit, it takes a bit more digging to find the panels that can hit a 30Hz lower limit. Many stop the fun at 40Hz, which can be an issue for users of less expensive video cards."

The digging will usually result in a monitor from a manufacturer who chose a more expensive panel which of course. like adding the MBR module, adds to the cost.

I am not making a judgement as to whether the cost increase is "worth it".... that judgment will vary according to each individual. But the claim that the two technologies are "the same" or provide the same features and performance is just incorrect.
Regarding the article....

1. Regarding the "out-of-box" accuracy, I expect that you will be able to download corrected ICC profiles for this monitor shortly on TFTcentral

2. When Acer made the move to 165 Hz in their Predator line, the 165 Hz was considered of no significant impact and many called it a gimmick. 165 Hz tho made one very important impact.... it allows a 120 Hz setting under ULMB, up from the 100 Hz that was available w/ the 144 Hz model. It would appear that 180 Hz offers no advantage here.

3. I keep wondering why we don't see IPS panels in this segment ... guess is that by the time one includes a gaming capable IPS panel and modern hi-end gaming technology to support it, the price is so close to a 1440p panel, most would just choose the larger panel.
I generally don't use THG reviews for decision purposes as the articles are the kind that "listen to Mom"" and follow the old adage "if ya don't have something nice to say, then don't say anything at all". As far as AOC, in my eyes, well let's just say I'm not a fan.... at least not till I see one I'm impressed with and that hasn't happened so far.

As far as response time goes.... wish we had more detail and with lag added in for all reviews so that a valid comparison can be made.

Would like to see something like this

User reviews on newegg aren't too reassuring for the G2460PF with just 12 peeps contributing:

5 eggs = 33%
4 eggs = 42%
3 eggs = 0%
2 eggs = 8%
1 egg = 17%

and the ones complaining are citing no support and failure to meet spec.

Compare that to the 1,171 Asus VG248QE reviews

5 eggs = 72%
4 eggs = 13%
3 eggs = 5%
2 eggs = 4%
1 egg = 5%

Again, for me I wouldn't touch that AOC ... I would touch this Asus either. Before I'd spend $500 on a TN 1080p panel, I'd save up another $200 and get a 1440p IPS, 165 Hz Acer Predator or Asus Swift. Peeps tend to keep monitors thru 2 or 3 builds so there's a tendency here to invest a bit and get something better since it will be around a lot longer.

With today's video cards (i.e. 1070) ... I think if pushed into a corner @ 1080p until I could afford a 1440p, I'd be more likely to choose a VG248QE w/ no G-Sync. With every game above 60 fps ... G-Sync or Freesync really won't be missed since a) it's value is really below that threshold and b) you can do motion blur reduction via the toasty strobelight utility. Could then use the Vg248QE as an accessory monitor for monitoring utilities, ventrillo, etc

It should be noted that the real benefits of G-sync really come into play when viewing lower frame rate content, around 45 - 60fps typically delivers the best results compared with Vsync on/off. At consistently higher frame rates as you get nearer to 144 fps the benefits of G-sync are not as great, but still apparent. There will be a gradual transition period for each user where the benefits of using G-sync decrease, and it may instead be better to use the ULMB feature included, which is not available when using G-sync. Higher end gaming machines might be able to push out higher frame rates more consistently and so you might find less benefit in using G-sync. The ULMB could then help in another very important area, helping to reduce the perceived motion blur caused by LCD displays. It's nice to have both G-sync and ULMB available to choose from certainly on these G-sync enabled displays.

Way above my padded price expectation of $400.
THG, can you do a blind test comparing 120 Hz monitor versus this?This is to find if there's any value to ever increasing refresh rates.


Jan 11, 2009
Not sure why people still make a big deal out of the lower refresh limit on FreeSync monitors. AMD has been compensating for that in software (called LFC), much like Nvidia does, for more than a year now. I've not seen screen tearing below 35Hz since FreeSync monitors first came out.

The refresh rate has no impact after a certain limit as the human mind has its own refresh rate what is limited. I think that something like 120 Hz is already higher as needed. This is the reason games are not pushing higher refresh rate. Games instead add more detail and image quality. I think this monitor is overkill. However ASUS will be able to sell it as some people with a lot of money will buy it. I will stick to a cheaper monitor with about 120 refresh rate.
It was not that long ago when folks were posting here on this forum that the human mind can't process more than 30 fps.

That doesn't account for the hardware module in all G-Syn monitors which provides ULMB ... when refresh went from 144 to 165 it allowed the setting under ULMB to go from 100 to 120 Hz

Go here

In the 2nd set of drop down, select:

Soccer Ball
90 fps
1.0 realistic
1000 pixels per sec

In the 3rd set of drop downs, do the same except 120 fps.

You do see a difference ..but it won't be visible unless you can display those refresh rates.

Still waiting for a PVA QHD+ gaming panel that isn't curved. Don't like the black levels on IPS and TN. All PVA gaming panels that have variable refresh rate and/or high refresh rates are curved which is a deal-breaker for me.

The article makes this ou tto be the first monitor to go this fast.....Asus themselves have a 240Hz 1080 monitor and a 200Hz 2560 * 1080 Ultrawide as do Acer and others.

Why even bother making this monitor? A 24 inch 1080P monitor with TN is not worth $500. Show me a 144Hz Gsync 1440P IPS =<4ms GTG monitor under $500. Seriously, either produce a better priced product or actually innovate on features.

Bought one when they were first released and the monitor is great. It might need some color corection like stated in the review but its great.
