    In this article, we will test the ROG Swift PG259QN 360Hz. This is a 25-inch 1920x1080 screen, it has an IPS-based panel (AVHA) with a staggering 360 Hz refresh rate as well as offering a Full-range G...

    Does VRR become less important at 360Hz? With my 165Hz display, there is still noticeable jitter when FPS doesn't match Hz so VRR is important. Does 360Hz lower that FPS/Hz mismatch jitter enough as to make it unnoticeable?

    "Now I called this monitor out at fake HDR, which it is. however, the brightness <snip>."

    'monitor out at fake hdr' - AS fake hdr??

    'however' - The h needs to be a capital.

    Great review though. There's a few glorious mistakes on here.

    Hmm, yeah I just scanned that segment again and fixed some typos. It's been a busy time and I had not checked the article properly on punctuation etc.

    I really don't understand what's with the Hz. I would rather see lowered response time that higher Hz.

    Anyway, just read couple articles about wireless monitors, very interesting and already here. Now that would be something new, I hate all those damn cables.

    It has 1ms GTG, and 360Hz... isn't this good enough?

    I have 240Hz 0.5ms MPRT 27`(very cheap monitor at 250 euro), but I would like to see the difference between the reviewed monitor and mine (sadly, 25 inch seems kinda small now)

    @Hilbert Hagedoorn This would be a good monitor to test GPU coil whine on :)

    The input filters on all GPU's are really pathetic. Here is buildzoid soldering on some decent caps(grey circular caps) for the input filters. This fixes coil whine and also will help with stability when OC'ing. The coil whine increases with the FPS being output from the card.

    I wonder if we see a difference at +960hz, diminishing returns and all that, we might need a 10x to see an obvious difference from 240hz

    1ms is not good enough, will still create ghosting.

    Usually the higher the HZ the lower the latency. Again i'll say this type of monitor is aimed at CSGO type games. It'll be a very good monitor for those twitch muscle shooters that need high fps/hz. I watch some CSGO tournaments and they never ever use more than 1080p so this is why a monitor like this is useful.

    As for coil whine i haven't ever heard what that sounds like. I game at 240HZ and games like Forza 4 run at between 200-240 fps on my 3090 without making much noise at all and only reaching 66C and thats with the current high ambient temps.

    Thank full I dont heal coil whine in my GPU most cause I still game on 60hz and for most part all gpu can do 60 fps with coil whine these days. Even when I get 120hz + monitor I will probably still cap fps to 60fps for that reason, plus i dont care to buy gpu that do more there expensive enough

    My old 1070 had some hilarious whine. Never did get to test it on my new 144hz monitor.

    Did anyone but the shittiest trolls ever really say that 24 fps is actually fine?

    Any time I see a monitor/screen it looks like it's lagging horribly then a split second later I remember it's because most screens are 60Hz.

    It's just peanuts though. The average latency in milliseconds of a specific refresh rate is:

    1000 / Hz / 2

    For 240Hz, that gives 2.08ms, for 360Hz it's 1.39ms. So 360Hz has 0.69ms lower latency. That's less than a millisecond.

    So I'd say this has nothing to do with latency. If you want to decrease latency by a somewhat relevant amount, let's say almost 2ms, then you need a 3000Hz display :p With a 1000Hz display, you'd get a 1.5ms benefit. So it's clear that we're deep in diminishing returns territory.

    Clearer motion is the actual benefit of very high Hz displays, not latency. If the framerate matches, of course. 360FPS@360Hz is going too look a bit clearer, but only if the panel's pixel response time is actually able to keep up. Keep in mind that these "1ms" or "0.5ms" pixel response times the monitors advertise are only valid for specific color transitions. The actual pixel response times you get in normal use are higher than that.

    Clearer motion becomes more and more important the larger the screen gets. Here's a fun little fact many people don't know: 120Hz looks exactly the same as 60Hz looks like on a display that's half the diagonal. So 60Hz on a 15" display looks exactly the same as 120Hz on a 30". That's why playing Nintendo 64 Zelda (a 20FPS game) on that old, small TV in the 90s was OK, while playing it on a modern large screen makes you eyes hurt. You can test this yourself on your 1440p monitor. Play a game at 120FPS in fullscreen, then switch to 60FPS in 720p windowed mode unscaled. It feels exactly as smooth as 120FPS fullscreen. (For a 1080p display you'd use 960x540 windowed instead, if the game actually support that.)

    This is also why a 30FPS console game is kinda OK-ish when you sit in your couch and relatively far away from your TV. But then a PC gamer tries a 30FPS game with the monitor right in front of them, they go into "how the hell are console peasants OK with 30FPS" mode.

    The larger our displays get, the higher the Hz and FPS we're gonna need to keep games looking smooth.

    Unfortunately, yes. Many people read something on the internet about why movies are 24FPS and then think that what they just read applies to other contexts as well. Being half-informed is often worse than not being informed at all.

    If it was 24" or less I would consider this. But 25" 1080p, this PPI, I could commit suicide.

    Going from 120 Hz to 240 Hz here, yes. Even without GSync, 90 fps on 240Hz feels way better than on 120Hz. It's not completely gone, but it does feel better overall.
