Style: 27" OLED QHD 0.03ms 240Hz ROG Monitor Arm
Absolutely stunning! I have a nice Bravia main OLED tv and I thought that screen was great, but the picture quality on the ROG Swift PG27AQDM-R is bar non the most stunning color rich panel I've ever used. My friend has a QD OLED panel and yes it's quite nice but it doesn't have a true 10bit panel. This one does, and it shows! Just played some BF6 and man it's an entirely different experience when you're dealing with unlimited contrast with 10bit color. Came with a color calibration certificate signed by the technician who tested it not twice but 3 times! I have downloaded the most recent firmware MC110 and everything is working great. I will say that HDR is kinda wack like washed out but honestly SDR looks like the HDR on my old mini-led monitor. Extremely bright but not over saturated like with other less premium panel technologies. DCI-P3 is what you want to use. Shows every bit of that 10bit color! I wouldn't have bought this monitor because of price but I couldn't resist the massive Amazon sale right now. Yes this is a WOLED, not QD OLED but you just wouldn't know because the design of this panel is supreme. Everything including the picture quality is perfect. Using 7500K gamma which brightens it up more. The brightness has got to be hitting over 1k knits but I don't have a way of measuring that so you'll just have to take my word for it. The panel materials are fantastic. The screen is glass, the anti glare coating is not noticeable to me and the arm the master kit comes with is 100% steel. Asus has won a new and longtime customer. You can just feel the quality. If I were you I'd get the screen and monitor arm master package. It's cheaper than just getting the screen itself lol.

Style: 27" Fast IPS QHD 180Hz G-SYNC USB-C
The media could not be loaded. this monitor has exceeded all my expectations !!! No dead pixels, no backlight bleed and exceptional contrast. Indeed, coming from a 1080p 27" 180hz monitor it's a bigger change than I thought it would be so, I'm over the moon. It has good black levels and great motion clarity. the only thing better in my eyes is an oled that's more than twice the price to look kind of better and maybe burn in sorry no thank you lol. I haven't seen any smearing or ghosting, I'm not really a hdr guy so I didn't care about that. the sdr mode is great for me and looks awesome, so many options to tune to your liking. Then there is the price and its crazy cheap for what you get when it's on sale but even at full price it is a good deal. It has a RGB backlight too it isn't super bright but looks pretty awesome when on!!! if you are looking for a good priced 1440p gaming monitor stop looking!!!! you found it!!!!!!! its only been a day but if anything happens ill update right away. I hope this can help someone S.P.

Style: 32" Fast VA Curved 180Hz QHD
The monitor has good picture quality and build. I do not think anything lesser than an OLED monitor would surpass. A few things I would like to see improved: * If it does not find the signal, it shuts off in like one second. Damned, need to leave some time for the user to figure what is going on. I get it energy saving is important, but should stay on for at least some ten seconds?! This is really annoying, all the more so because HDMI seems to have issues with waking up when the laptop is put to sleep. * Between day time and night time, monitor brightness needs adjusting. There should have been some easier means to do this, ideally even automated with an ambient light sensor. However, various monitors do not seem to support this. This monitor does allow having two setting profiles and you can customize the button to switching between these with just two clicks (I have set up upward click on its button to open setting 1 with larger brightness and downward click to open setting 2 with lower brightness. * For some reason, monitors do not allow lowering the brightness below a certain level, which itself I find too high for night environments. I wish they allow letting the brightness scale do all the way to zero.

Style: 27" FHD 144Hz FreeSync Height Adjust
This is my experience with the Asus VG279Q. First off I want to clarify that prior to this monitor I have only ever used 1080p 60Hz TN panels. So this was my first experience with anything over 60HZ, my first experience with an IPS (IHVA) panel, and also my first experience with Variable refresh rate (Freesync/Gsync). The first thing I noticed was the limited viewing angle from above, something I'm still struggling to get used to. I know that for my TN panels I get the best viewing angle when my eyes are about level with the top of the monitor. And if I stand up the monitor still looks fine. My TN only looked it's worst when viewed from the floor looking upwards. Since I never sit on the floor and look up at it the TN viewing angles were adequate. For this IPS panel I get the best viewing angles when my eyes are about level with the bottom of the monitor or looking at it from below. And it has the worst viewing angle when looking down at it from any position higher than perfectly eye level. So raising it up was my first step to reduce the washed out foggy angle. The next step was to lower the brightness from the default 60 or so, down to around 23 *(I'm in a dark room). That helped to get a calm neutral picture, especially for white file explorer windows or web pages. This being my first IPS, if I had to describe the IPS glow, I think mine is only a bit on the bottom left corner, fairly subtle. But the viewing angle from above turns the image into a silver grey fog when viewing at anything but eye level. If you're eye level or below, then you can have a good image even when viewing off center for the side. However, you really notice an issue when the monitor falls below your eye level if you stand up. I knew with my TN panel that the picture would get bad when viewed at the wrong angles, but this is more extreme because the monitor turns so foggy from above as seen in the pics. So it's really bothering me to the point that I kind of wished I had gone with a TN that had these other features. However, now that I know it's limitations I just avoid the problem angle and it's all good. The settings can be dialed in more with certain modes. For example I use Racing Mode because it allows me to use the Blue Light filter option whereas the FPS mode does not for some reason. The blue light filter isn't needed, except when it's a really dark room then it can come in handy so I like having the option. If I know I won't be using the blue light filter I made a profile for FPS mode because it allows me to adjust the saturation, color temp and skin tone options whereas racing doesn't for some reason. It's just weird that they make you pick and choose. The sRGB mode doesn't allow you to change anything, I guess they figure it doesn't need it. So I was thinking of choosing it - but I like to tinker more than the average guy. The SDR of contrast is genuinely full range and not limited range SDR like my old Asus VE258Q. The gamma is about .08 too dark, but using either Nvidia's gamma slider, or the built-in OSD shadow boost on level 1 take care of that. The dreaded pixel density issue everyone seemed to worry about in a 27" FHD monitor is thankfully not an issue whatsoever. I don't notice even a hint of pixel density issue, honestly. So that's a relief. My VG279Q was stuck in 60HZ at first under the Nvidia display options heading for "native 1920x1080" But I was able to scroll down and choose a 2nd 1920x1080 option in the drop down that enabled all of the refresh rates. I immediately wanted to put it on 144HZ and enable the Gsync feature in the Nvidia control panel. I had to download the latest Nvidia drivers in order to get the Gsync feature to show up. After that I turned it on and went into a fast paced shooter. I put the graphics at a level to achieve a constant 144 fps, and I used the monitor's built in frame rate display counter as well as Nvidia's frame rate counter. The smoothness was outstanding. Everything was overall less blurry. Also no tearing ever. I loaded up Ace Combat 7 and flew around at 144fps locked and no tearing - an outstanding experience. I tried other things like running MAME and emulating old Mortal Kombat 1 with it's weird 55HZ native refresh rate - and the Gsync allowed me to run at a it's 55HZ perfectly with no tearing. So I'm really happy with Gsync, and really happy with having more than 60HZ for the first time. These features are so cool, that I definitely wouldn't want to go back to 60HZ or no Gsync. As far as movies, 27" is superior to common 24" - 25" sized gaming monitors obviously. Watching movies benefits from the larger screen. The IPS's improved rich, vibrant colors are satisfying. Just gotta watch out for your viewing angle of course. Web browsing, writing this comment, it's nice and clear at 144HZ. It's cool to see the mouse move around in more focus because the monitor can keep up with it better. This comes in handy when I tested drawing in Gimp with my Wacom tablet and stylus. As I make little gestures in my shading and drawing lines, etc - the higher refresh rate keeps up with everything and feels less laggy in the strokes. As far as colors go - they're good. Again, it's just that darn viewing angle issue that makes blacks look silverish and foggy from angles. If it wasn't for that then I would give it 5 stars. No dead pixels, no backlight bleed. Just some IPS glow (which is something all IPS panels have). So I figure I'll just get used to that. And a lot of great features. It's around 3 to 4 ms response time normally and around 1ms response time in the ELMB strobing mode. But that mode is greyed out in the OSD unless you disable Freesync and go into your PC's display settings and select a lower refresh rate like 120HZ or lower. I tried the ELMB mode, and it works fine. I can notice a sharper image in motion blur tests with ELMB enabled, but there is some ghosting. With ELMB disabled there's no ghosting but the object is blurrier. I'm not sensitive enough to notice the difference between 1ms and 5ms response time in game though. However, I am very sensitive to screen tearing that I get when Freesync/Gsync is disabled. Also once I got used to 144HZ, going down to 120HZ looked laggier - so I'll just stick with the 144HZ and Freesync/Gsync. All in all, I'm happy. I'm not returning this monitor. I think it was well worth the price. I learned that TN isn't as bad as I thought as it turns out. People always said IPS has better viewing angles, but it's not the case. So my recommendation would be to get a monitor that has all these features but TN if you require a more versatile viewing angle when seated or standing. Or to get this monitor if you can ensure you'll only use it at eye level or lower. My bottom left corner is a bit foggy where it should be black. Not extremely mind you, but noticeable to me when I'm looking for it. My settings that I prefer: Racing Mode, Brightness: 23, Contrast: 70, Saturation: 50, Color Temp: User mode (red:93,green:92,blue:100), Skin Tone: Natural, Smart View OFF, Sharpness: 50, Trace Free: 60, Vivid Pixel: 0, ASCR: OFF, Freesync: ON, ELMB: OFF, Shadow Boost: OFF (bumped up gamma in Nvidia control panel by .08). Other than bad viewing angles from above - everything looks beautiful with these settings. In the included pictures I show a movie still image at a good and bad angle, a black screen at a good and bad angle in the light, and then good and bad angles of solid black, red, green, and blue screens under ambient lighting.
