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.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The PG27AQDM has three HDR picture modes that appear whenever an HDR10 signal is present. You can also adjust the brightness if you wish though I didn’t find a need for this.

HDR Brightness and Contrast

A lot is made of peak brightness when it comes to HDR, and while that is a factor, black levels are a much more important metric. That’s where OLED has the advantage. The PG27AQDM has plenty of peak output, over 870 nits, when measuring a 25% window. Asus claims 1,000 nits which I don’t doubt, but I didn’t have a small enough window pattern to achieve that number. However, the zero black level means HDR dynamic range is infinite. Can you tell the difference between an OLED and the PD32M? Having just reviewed it, the answer is yes. In a side-by-side comparison, the PG27AQDM has a deeper and more three-dimensional image for HDR and SDR. If you want the ultimate in picture realism, OLED has no equal.

Grayscale, EOTF and Color

The PG27AQDM’s HDR grayscale tracking is a tad cool in the brighter parts of the image, but the error is visually small. I would be happy to have access to the RGB sliders to correct this, but that is a minor point. The luminance curve tracks a little dark until the mid-tones where it crosses the reference line to a slight overshoot. The transition point is at 70%, meaning all values over that are tone-mapped by the display rather than the content metadata. This is typical performance for a bright monitor, so what you’re seeing here is a good thing.

The PG27AQDM covers the DCI-P3 gamut with some over-saturation but nothing that will reduce detail. The HDR image has rich and vibrant colors enhanced by deep contrast. The Rec.2020 chart shows much the same behavior. Color runs out around 80%, which is typical of most OLEDs. The Asus’ HDR image quality is stunning, but other OLEDs are on par with it. However, it is on another level above Mini LED.

    If I lived on USA and got paid in dollars, I wouldn't even consider this expensive, at all. People complaining about the 4070 being $600.. just imagine having to pay $800 for the cheapest ass 1440p IPS 144hz or $2400 for a 3060. In Brazil my friends that's what it cost. A 5K gaming rig here is really as good as a 144hz IPS monitor powered by a 3060, so really, if you live in USA (and EUR) stop complaining about price. If I can afford a 5k gaming rig in Brazil you surely can afford a 5k gaming rig in USA unless you are unemployed or you didn't figure how to make good use of your money. I work as a Uber driver, have two kids, live in front of the beach. If I can, bro you surely can as well, just plan ahead and save money 3 to 4 months, stop expending in unnecessary stuff and you'll get there.. with a OLED 240HZ and a RTX 4090 while we international fellas will wait another 6 or 10 years to have it accessible for us.

    EDIT: the minimum wage here is R$1300 while in US is $1300 so I used "$" as "money", not dollars. A 3060 here is R$2400 (roughly $480 dollars)

    If you lived in the USA you would know that a 2 bedroom apartment can cost $1500-$2000 a month to rent in areas with decent pay. You would also know that going to the doctor can cots $150 for 15 minute visit or that a visit to the emergency room can cost thousands or dollars and bankrupt you or take away your life savings. Electronics can be cheap compared to the rest of the world but everything else is stacked against you.

    $2400 for a 3060 is mental, I found a 3060Ti for $330 used and I am from Pakistan. Even the Xeneon flex ( spent $1849, Only 240Hz OLED that was available, atleast it's a bendable 45 inch UW) and Aorus 7900XTX I have were reasonable ($1219, cost $1100 something in US), only the 4090 is $2k used which is a bummer, but I shouldn't complain because that's still cheaper than that 3060 there. I am jobless ( under 17) and my parents decide my PC's budget, thankfully it's more on the generous side.

    But that's exactly my point.. my rent is $2000 and doctor here is $300 a single visit, it's not different at all. I spend no kidding $2500 a month with food, cleaning etc.. the only real difference is that the money that is left when all the bills are paid is simply not enough to buy a rtx 3060 which costs here S2400, but that I can afford if I save up for several months. If you live in the US you can buy this OLED, a 5800x3d and a RTX 4080 with the same "spare money" I can afford a measly 3060. And honestly here in Brazil, the average person earning 5 times less than someone born in US, we r still pretty good compared to other countries that are double poor. My reasoning is that anyone living in the US complaining about these prices is either unemployed or a cry baby, may sound harsh but my honest opinion.

    Btw.. just to share a personal bill I had recently, while in Brazil you have free access to ER, I spent last month $8000 in medical bills because the service I needed with haste wasn't available for free.. so yeah, it's tough for everyone.

    Lol my bad.. I didn't make it clear that "$" equals "money" in the values I shared. I wrote like that because in Brazil the minimum wage is around R$1300 while in USA it's around $1300. The other guy answered his rent can cost as much as $2000.. while my rent also costs me R$2000.. but while $2400 can buy him a RTX 4080 plus the OLED and a CPU upgrade, everything new, here R$2400 (roughly $480) can buy me a second hand RTX 3060. And btw.. your gear, that's so much money here In Brazil it could buy you a wife

    About the monitor.. someday in the future when I make the jump from 24"1080p, after so many years, I definitely won't be upgrading to a 27"1440p, that feels like way to little of a improvement, even if it's OLED and 240hz. I don't understand why someone would today choose this one over the 34"3440p 165hz when the prices almost match, rlly. While it seems I wouldnt miss those extra fps, the other way around giving up the extra screen immersion rlly feels like a compromise I wouldn't make. This Asus looks like the endgame monitor before we get to the 1000hz era, what I trully want as a upgrade is this exact performance here but 34" 3440p. That's my endgame, paired with a neo qled 65" 8K 120Hz (if I can't afford the OLED)

    You cannot compare like this, it does not make sense... Try this.

    If I got paid in dollars, ...
    Myself, in Berlin, I have a bit of money left at the end of the month, which I can save up for e.g. hardware, or for going to a concert, etc. But e.g. in Texas, the minimum wage is $7.25 per hour, which applies to around 400,000 workers there. In most places there, more than half of that will go towards rent, which doesn't really leave much for saving up, in particular in places such as Dallas County, where it takes a living wage of nearly $18 per hour for a single adult to just support their basic needs.

    Similarly in Brazil, if you'd be having minimum wage, you'd cover only half of what your current living costs are, wouldn't you? Which isn't to say that there aren't some with higher income, who are boozing it away, or some who may at least try to apply for a job, instead of hoping to get hardware for free. But to imply that everyone with a job surely can afford the highest-end rig there is, that's generalizing it too much, isn't it?

    Well, if you consider that today April 24th 2023 1USD equals 5,05BRL, your interpretation of how much it costs us to live here in Brazil is what does not make sense...

    You have to take into consideration that you guys are payed in USD and us in BRL, but we don't get payed 5,05 times the value that you get. We actually are payed half or even less than what a minimum wage american gets.

    The bare minimum wage in US is 7,50 USD per hour, some states pay a little more and some pay almost double of that.
    Here in Brazil I get payed less than half of that 7,50USD per hour.
    And my monthly salary is actually more than two brazilian minimum wage.

    For every hour that a "lowest minimum wage american" works, I have to work more than double of that to get the same amount of money.
    But if I was payed the brazilian minimum wage, I would have to work almost 5 times more than the "lowest minimum wage american" to get the same money... So now you start to get an idea of what oofdragon is trying to say.

    Look at a "McMeal at McDonalds (or Equivalent Combo Meal)", it costs you "only" 10 bucks, that is about 1h20min of work at max for an american, but for us here in bananaland it costs 35BRL, which is almost 6 hours of work if you get payed minimum wage!!!
    But I guess noone here in Brazil is eating McDonalds every day, so lets compare something that is more common in everyday life.

    Milk (regular), (1 liter) costs you 8min14sec of work to buy, but costs us 59min48sec.
    Rice (white), (1kg) costs you 20min, but to us it's 1h2sec.
    Beef Round (1kg) (or Equivalent Back Leg Red Meat) costs you 1h48min43sec, to us it's 7h32min56sec.
    Gasoline (1 liter) is 9min51sec for you, it's 1h5min22sec for us.
    A Toyota Corolla Sedan 1.6l 97kW Comfort (Or Equivalent New Car) costs you 3,435h35min21sec, and to us it's 23,694h5min44sec, and we have to pay 5% of the value of the car per year in a tax until the car is 20 years old. Yeah, that's true. We pay a lot for the car itself, which already has a lot of taxes included in its pricetag, and then we still have to pay "another car" to the government in a stupid tax until the car is 20 years old!! Brasil-sil-sil!!!
    And let's not forget the pride and jewelry of our beloved country, a Banana (1kg) costs you 13min7sec and 1h9min56sec to us plebs.

    To sum it up, because I know nobody will read all this crap I just wrote, what oofdragon and I are trying to say is that we (and most people around the world to be honest...) have to work much more to buy the same things that someone in US or another rich country have to.

    We don't mean to say that a 1,000,00 USD OLED Monitor is 'cheap' by any means, but is 'cheaper' to you guys than to the rest of the world.
