Just checked: PG27 production starts now in May, so mid/late May/early June for first markets depending on how it's being shipped.

Not sure X series yet. It's often mostly waiting for mass-production of panel availability and/or mass production to meet a certain quality standard.

For the record: Monitors don't wait for graphics cards. They just launch on their own schedule.*

My original post:

On this retailer site, the Acer Predator X27 is listed as to be shipped April 5th. Because ASUS usually release their version a little earlier than Acer/the other manufacturers, it is likely that the PG27UQ will be released (assuming that shipping date is correct) during March, this would also still stick to the Q1 2018 release window.


For reference, see the posts in this thread:

Percieved loudness is subjective, but not as much as you think. One flaw with this is you're not able to capture the frequency of the noise. A high performance fan can have similar decibels at a very low frequency. Low frequency would be just the wind moving through the fan noise. These fans have a high pitch noise compared to normal fans, which most definitely would be a higher than average frequency. You would need something professional to measure that. So your phone has a difficult time accurately measured percieved loudness, it's a very flawed method of measuring.

This is why people are annoyed with the particular fan in the monitor. A lot of people, including myself, are asking for a better fan inside. Humans tend to appreciate low frequency noise than high frequency.



There's like ~40 games with HDR. Most of them not being popular. Most of them not owned by a single consumer. Just looking around, people have at most 5ish games with HDR. Almost no one has more than 10.

A bigger issue is that almost no one have more than a few HDR games they play most of the time (there's only so much time you can spend on a game like assassins creed). Most popular games are stuff with multiplayer and a competitive mode, whether it be an MMO like Dota or FPS like csgo. The only popular games like that with HDR are like battlefield, COD, and some racing games.

There was one more issue with the monitor, and it was like reverse blooming??? Limscave showed it properly, but a moving object on the edge would seem darker. If you move a window to the left, the left edge of the window will be dark, almost as if the local dimming is really slow (i had it on extreme speed). Believe it or not, after I noticed it, I was super annoyed about it.

Actually I notice the same thing, but once switch to gradual mode the issue is gone, median and fast modes all have the issue. Not only in moving object, if one pay attention to the windows boot screen, the blue windows icon's edge becomes slightly yellow-ish, or basically anything that has a bright object in a relatively dark background, the edges and corners are dimmed, and have significant color shift due to this, try the DisplayHDR test you can see the effect easily. This annoys me, as I can tolerate blooming, but I am very sensitive to local color shifts, especially a significant color shift like this.
Looks to me that the significant less blooming than UP2718Q that I mentioned in one of the post is achieved by aggressively reduce the local brightness around the edge, also by keeping the back-light on (with extremely low brightness) when display image that is completely black. Switching to gradual solve this by using a less aggressive dimming algorithm, but then it makes the blooming much more obvious.
Now when comparing to UP2718Q, on gradual variable back-light, the LED array's response time on PG27UQ is on par, so the only things that are attractive are G-SYNC and higher than average refresh rate. Looking forward to use the first MiniLED display.

LG came out and replaced my panel onsite service just for having burn in on my LG oled C7 tv now thats top notch service and it was a complete new panel not a refurbished unit like some companies have done in the past such as HP when I had the HP 5k display when the panel died they sent me a refurbished unit

Just received the ASUS PG27UQ today. The HDR is amazing!! No need for 98Hz 10bit. 120Hz 8bit looks fine and I can't tell a difference with the banding and colors. I have variable backlight set to on even for SDR content. The IPS glow is dirty looking so that's why I keep variable back-light on. My only complaint is Windows set to HDR looks way better on the desktop vs with HDR off. Everything looks way dimmer with HDR off. I don't know if i'm spoiled now with HDR or the SDR nits of this monitor is just too low. My other monitor ASUS MG279Q was way brighter in SDR mode vs the PG27UQ. No complaints with the fan. I can't hear it over my PC with and without open back headphones.
Also, is the ASUS aura software required to get AURA to work on this monitor? I have AURA enabled on the monitor but it isn't working.

When you turn on HDR in a game, you automatically get 10bit signal. If you're using above 98hz, you also get chroma subsampling. Theres no way to prevent that.

This is also the first time I heard anyone compliment windows HDR. Windows HDR on desktop should dim the screen, not make it brighter, you might have something set differently or idk. You can always turn up the reference nits in the monitor's OSD.

Everyone who bought this monitor seems to have a problem with Aura sync, so dont bother with it. You are supposed to use the software, I cant find anyone who actually got it to work lol.

No. you're quite mistaking. I don't get chroma sampling with HDR at 120Hz. I tested with this https://linustechtips.com/main/uploads/monthly_2016_11/TextTest_4k.png.8fc940e703b15b869281af8c8d22f...
HDR and WCG mode actually looks better for me. It's brighter and more vivid than having it disabled. FYI, I have "brightness for sdr content" set to max. My other monitor is way brighter at SDR. I don't know what's up with the SDR on the ASUS PG27UQ but it's dim compared to my ASUS MG279Q. Also, I just got done testing G-sync and it's not working properly :mad:. I downloaded G-SYNC Pendulum Demo and i get screen tearing when my FPS exceeds 94 fps, WTF??

That's how G-sync works. Look it up. https://www.blurbusters.com/gsync/gsync101-input-lag-tests-and-settings/

i know all about that guide. I'm telling you i'm still getting screen tearing with Gsync enabled.

well you clearly dont because you are still complaining saying "still getting screen tearing with Gsync enabled"

you will get tearing if your framerate exceeds your current refresh. Tyr it in a game by limiting your fps

[greekwow]

G sync needs also v sync on just only for cap the fps.
So Just enable g sync and v sync on nvidia control panel and you are ready.

I never tested subsampling in windows, but I can guarentee it happens in games. Plus 8bit color makes HDR kind of pointless. You dont get to see all the shades that create a fluent, non banding, image.
