Asus ROG Swift PG259QN 360Hz Monitor Review: Elite Speed

360Hz is the new 240Hz.

The ROG Swift PG259QN’s Racing mode yields a reasonably accurate image that has a little room for improvement. All calibration controls are available, so optimal performance is easy to achieve (see our recommended calibration settings on page 1).

Grayscale and Gamma Tracking

We describe our grayscale and gamma tests in detail here.

Our initial measurement run showed a slightly warm tint to the grayscale step pattern. Though the errors are visible in steps above 40% brightness, it didn’t have a huge effect on the picture, but the image didn’t pop quite as much as it could.

Gamma was near-perfect with only a small dip at 10%, indicating a rise in luminance at that brightness level.

Our calibration produced a professional-grade grayscale with all errors below a Delta E (dE) of 1. This improved perceived contrast and brought out highlights more for a three-dimensional look and better color saturation. Gamma was unchanged.

A 3.65dE average grayscale means you don’t really need to calibrate the PG259QN, but probably should. Just a few tweaks are needed to reduce the error to a tiny 0.58dE. Only the PG259QN’s stablemate, the VG259QM, and the Samsung can boast better. The naked eye will see no difference among the three.

Gamma tracks tightly at a small 0.21 range of values. Average error is 2.15 for a 2.27% deviation from 2.2. Since the error is only at 10%, you won’t see a problem in real-world content.

The PG259QN is an sRGB monitor with no option for extended color. It covers that spec very accurately, with a nearly spot-on initial measurement. The warm white point pulls red and cyan a little off their hue targets and blue is slightly over-saturated at the 100% mark.

Our calibration fixed those errors neatly, taking the PG259QN to a high level of color accuracy. By the numbers, magenta is a little off in hue, and the 80% red point is about 5% under-saturated. But to the naked eye, the monitor looked very good post-calibration.

All of the monitors in our sample group calibrate to a high color accuracy standard. The PG259QN ended up mid-pack with an excellent 1.68dE result. There is nothing to complain about here.

None of our super-speedy screens feature a wide color gamut. But the PG259QN covers more of the sRGB and DCI-P3 color spaces than the others. It is very colorful in practice, but a DCI-P3-native monitor would render greater color saturation. If sRGB accuracy is a priority for you, this screen provides excellent performance. If you need critical accuracy, we recommend a software profile.

    That's great, but I prefer resolution over frame rate. I have a 1440p Asus ROG 27" with 144hz and G-sync and I'm fine with that for now. If I were going to upgrade for that price I would want it to be at least 1440p 360hz or 4k 144hz or faster and still 27".

    No idea why companies are focusing on high refresh rates at 1080p. This is the 4k generation, 2k was last gen and we should be getting more choices in the 4k range. Which I'm sure we will, but I don't see anyone paying $700 for a 1080p high refresh rate monitor when for $100 more you can get a 144hz 4k 27" monitor.
    Infact, this one is only 24.5"?
    What? What is that price for that resolution, you're really just paying for 360hz?

    What are all the included latencies in your Absolute Input Lag testing? Could there potentially be mouse button latency included? Also system latency? What are frame-times etc.?

    This is for competitive gamers and that's it. They are notorious for running high framerate at low resolution. Even at 1080p, almost all effect settings are turned off. It's kinda crap to watch but it works for them. I prefer 2K at 27". I'm at 165hz now but I'm looking at a 4K 27". My 3080 should be in on Tuesday.

    I should compliment Toms Hardware for improved mainstream-writing description of how motion blur is reduced -- doubling Hz halves display motion blur, as an alternative to strobing. Yesterday's media used to dismiss high Hz, or was not familiar with the benefits of high Hz.

    I would, recommend that TomsHardware do pursuit camera tests with instructions at the forums:

    Not necessarily. If you own a 120Hz iPad, you'll notice web browser scrolling is 2x clearer. LCD motion blur halves when LCD Hz doubles. And my 360 Hz monitor has 1/6th web browser scrolling motion blur of a 60 Hz LCD monitor.

    I have the PG259QN here too, and it's absolutely lovely, especially when combined with the Razer 8000 Hz mouse (I have a prototype here).

    4K was a $10,000 frivolity in 2001. Today, 4K is a $299 Walmart special. The mainstreaming of 120 Hz is slowly beginning this decade, with future iPhone/Android devices standardizing at least 120 Hz. But eventually, 240 Hz will be a freebie feature much like Retina screens.

    We've almost retina'd out resolution, but we are far away from retina refresh rates. There is already a laboratory engineering path to an 8K 1000Hz display, though that will take many years of progress to reach.

    High-Hz isn't just for esports anymore. Though the highest Hz is still expensive and mainly of interest to bigger-budget users.

    I was going to post about your site. My eyes hurt and I cringe every time i see sideways pans in films and I check your site from time to time to see how the race to 1000hz is going. I get why these people like higher resolutions, but even back in the day of the 3DFX Voodoo1 and Voodoo2 SLI I preferred higher framerate over the resolution bumps. I want to see that 1000 hz target hit and this is a positive step that moves the bar even if just a bit towards the goal we need in display technology.
