Incredible shipping speed.

Zero dead pixels.

After watching some youtube videos in 4k as well as upgrading my netflix account I can say that this monitor delivers a phenomenal picture. The upscale from lower definition video also delivers a stunning picture. I can not wait for the new graphics cards so that I can game with this.

I have not been able to test free sync yet as I am waiting for the new AMD cards before I upgrade but will update back once I have that setup.

While the indicator light is slightly annoying I have already gotten use to it after a day. The brushed metal look of the bottom portion looks amazing.

UPDATE:

After a little more than a month of use I am even more pleased. I spent a little bit of time tuning the picture and really got all of y settings dialed in and now I hate to look at my other monitors next to this. I reall wish they sold one somewhere in the area of 25" so that I could replace my other 3 monitors with those.

Was looking for an upgrade from 1080 60 Hz to 1440 with 144hz. Like others who wanted great colors end up buying the Asus Swift but did not like the insane bleed which makes certain area bright. For the price you would think it would be high quality. I return and decide to save some money and bought this gem. I was lucky enough to buy this monitor for a little under $500.  Probably best price for the monitor around this performance level. The build quality is definitely better, love the stand and simplistic design of this monitor its super clean.
G-Sync is great if you have an Nvidia card. Else there was this other BenQ monitor around the same price range but with Freesync that works well with AMD Radeon cards.
Overall this monitor is amazing I don't even notice the difference between this and the IPS panel. The color is definitely more washed when viewing a darker image.
Like other positive reviews mention you definitely want to TURN OFF DEEP SLEEP!!! Calibrate the color to your liking and lower the gamma a bit to eliminate the washed colors. Make sure G Sync is on in the Nvidia control panel. Turn off v sync if you fps is lower than 144fps and vice versa.  If you also play console on this monitor I recommend changing one of the shortcut key under personalize to change Input Source makes life easier.

The xi monitor lineup is proving to be excellent selection.  I used the 20xi for about 1.5 years before upgrading to the 22xi.  The 20xis performed flawlessly, and were near-perfect in a 3 monitor setup.  But eventually I wanted the more-common 1920x1080 resolution, and the additional screen size, so I went with 3 22xis as an upgrade.

Both models (20xi and 22xi) have excellent display qualities.  Crisp images, great viewing angles due to IPS, etc.  I'm not a fan of the plastic stands, but I have mine vesa mounted on the Ergotech triple monitor stand.  Even with the stock stand these 22xis are light, thin, and non-intrusive on a desk, but even more so when vesa mounted via adapters.

And after a week of use I'm pleased so far.  I'm not sure that you can find a better monitor for the money.

The only thing I'm still trying to get used to is the increased pixel density.  The 20xi had 96ppi, while these 22xis have 108 ppi.  I didn't think that'd be very noticeable, but I still find myself adjusting scale on some pages.  I think a 23xi would bring the pixel densitay back down to a perfect range, but w/3 monitors it'd likely be too wide for comfort.

These monitors are still kicking, and kicking hard. I'm finally gearing up nearly 4 years after I purchased them to get a third one so I can have 3 matching monitors for my immersive gaming setup. I no longer use these with a MacBook, I have built a gaming computer now and these keep up with everything thrown at it, especially since I upgraded my card to a Asus 1060 over an old XFX 7870. I just wish Acer had the foresight to add HDMI to these, because it's getting harder to find graphics cards with more than one DVI port anymore.

Keep in mind though, that these are huge displays. The other reviewer who said that three of them take up over 6 feet of space was not kidding. If you're looking at getting several of these to play games on, make sure your desk is at least 6 feet wide. L shape desks don't have to be quite as wide, but still expect to not have any actually usable desktop space on top of your desk. You'll be able to put a keyboard and mouse in front of the monitor and that's it. Unless you have a crazy deep desk, which also happens to be very wide (which doesn't happen often). If you have a desk under 6 feet wide or value your desktop workspace, go with a smaller display for your multi monitor set up.

Overall, these are some of the best monitors that I have ever used and will recommend them to anyone. Especially now that they are $190 instead of the $250 I paid 4 years ago.

Original Review
The picture quality on these is even better than my 1080p Visio TV. The pictures are absolutely stunning, and crisp, and very well colored. The display looks good from almost every angle. I bought two of them to use with my docked MacBook (along with the HIS external USB video card) and I won't ever go back to a single monitor. The only complaint that I have is that one of the displays had big, nasty fingerprints all over it. This was easily cleaned, but as the displays were still factory sealed, I can only blame the Acer workforce for that. However, still love these monitors, and they look amazing on glass computer desks!

I love this monitor!  Multitasking, movies, gaming, everything is better on an ultra-wide 3440x1440 21:9 monitor.  After playing Battlefield 1 on this i'll never go back to 1080p 16:9.  I've only had it for about a week, but I'm very impressed so far.  Also, it looks amazing next to my custom-built pc.  It's pricey, but i have no regrets about my purchase.

I've been wanting one of these for several months, and almost waited too long because Acer discontinued it recently. I couldn't find one anywhere, until I stumbled upon a single unit waiting for me on amazon. I can't believe what $299. bought; a big 27" screen, a thin, bright LED-backlit display, and a gorgeous modernistic design that looks just amazing on my desk. No cheesy plastic here; A brushed metal base with blue-lighted electronic controls and side effects, and a thin matted bezel surrounding a beautifully bright anti-glare treated display. I understand that this model won several European design awards, and I can see why. Also, it has 3 video imputs! I really appreciate the dual digital input support (HDMI), since this monitor services both my desktop PC and a Sony PS3 gaming console. This beautiful beast has an internal speaker, if that's important to you. Also, HDMI, VGA, and audio cables were included in the box. It has a 3-year return-to-depot warranty. My quibbles are few and minor; A higher resolution from the native 1920 X 1080 (1080p) would help to get the most from the large display size, I needed a $5. adapter to convert my PC's DVI output to HDMI, and I find switching video inputs through the menus is a little cumbersome. Nevertheless, this monitor functions just fine for my needs, and sure looks awful good doing it. This one's a keeper!

Every thing looks great. 1440p is the sweet spot for gaming and deskwork. 4k content and gaming is nonexistent. Unless you have 2 980 ti SLI, it near impossible to keep a 60 fps in demanding games such as gtav or witcher 3. This monitor even without gsync is fine because of its 144 refresh and ips panel. The only problem is that the buttons for the menu are awkwardly on the side and using them isn't user friendly.

Excellent Monitor,  run with gtx  970 for playing games...this monitor is hugh and crystal clear.  I aggree with all others posting.  speakers are like 5 buck speakers that stick out the side and take up space..they do not get to high in sound.  and they also get buzzing sometimes with bass pushed.

I know they are beats speakers..but I think they be safer to remove there branding from theses.

I've had this monitor now for almost a month and I've hooked it up to all of my devices. I bought it when it was a featured lightning deal for $129 and it was a great deal considering I paid $129 for not just a 23" LED but an "IPS" LED! For its size, 23" imho is just right and definitely an upgrade from my old 19". It's also an LED screen which makes it brighter and has better contrast levels and viewing angles than that LCD. That one was a 19" Samsung LCD PC monitor I'd had since 2007 and it has great colors even today but this one is very clear, very sharp, and the frame is sturdy (the Samsung's glossy plastic fame got a crack early on and is full of scratches now). I also really like the base it stands on. My one complaint is that the controls for the OSD are hard to reach and are touch sensitive so it can be difficult to navigate the options since they are inset under the screen on the base. I guess it's a case of style versus function. One BIG surprise to me was that it even has built-in SRS Premium speakers! I guess I didn't really read through the description, but that makes the value on this thing just incredible! I've used it as an auxiliary monitor for a laptop, a main monitor for a desktop, an output display for a smartphone, and even a full on 1080p HDTV display for an Xbox 360. In each application the monitor is flawless. Initially you might have to adjust settings to your personal preference (the speakers were at maximum volume for instance).

Here's my breakdown

+ IPS LED technology has superb viewing angles
+ black levels/contrast ratio is superb
+ the screen is bright and colors are reproduced vibrantly
+ 23" is a perfect size, not too big not too small
+ sturdy and stylish frame construction and base
+ connectivity options include HDMI, DVI with HDCP, VGA, audio in and out
+ built-in SRS Premium Sound speakers deliver clear and crisp experience
+ eco friendly and energy efficient design saves power and doesn't compromise performance

- the OSD controls are hard to reach and touch sensitive, weird combo
- no DisplayPort

I would recommend this monitor to anyone regardless of application.

update 10-2015

Wow, I've had this monitor for a long time now! Just taking a minute to update my original review, I originally gave it a 4 star rating but now I feel it's a 5 star product for sure. The colors and brightness are just like day 1 and the frame and base are still solid. In fact I would highly recommend this monitor just for how sturdy it is and how it's held up over time. My friend's monitor has this crappy stand and he complains how it wiggles when he shakes the table or even just while normally typing. I could get a 1440p gaming monitor if I wanted but this thing is still kicking hard and suffices for my use.

I'm writing this review because all the ones I read before buying it were saying they were using {Insert GPU here) and playing games with no problem. Which I should of known better..lol That said, the monitor itself is amazing! I came from an ASUS 27'' 144hz 1080p monitor and I'm so glad I took the plunge. Only downside is I had to upgrade my GPU. I did have a GTX980 but would only get 30-40 fps in games like The Witcher 3, Fallout 4, etc. Don't get me wrong you can definitely play at those frames thanks to Gsync, but if your gonna invest in a $1300 monitor you are not maximizing its capabilities. With a GTX 980 you will be playing games between medium with some options on high. Ultra is out of the question. IMO it makes no sense to spend that kind of money on a monitor to only play on med/high at the highest 50fps. If your playing at those frames then you might as well buy a different monitor because you will not need a 60+hertz monitor. Playing at 50< frames you will only need a 60hz monitor so save you some money and buy a different monitor. Those saying they are using this monitor with a single 980 or lower and are happy, are just wasting monitor honestly. This monitor is 3440 x 1440p and has 30% MORE pixels than a 2560 x 1440p. You can imagine the horsepower you need to push this thing. It is just shy of 4k actually. There is no way a single GTX 980 or lower will give you a constant 60fps on high/ultra in these AAA titles. Even at 60fps you would only need a refresh rate at 60hz because you are lacking the FPS to use anything higher. I ended up buying a Zotac GTX 980 Ti AMP EXTREME 6gb GPU. Which should be suffix for the time being. Found here (http://www.amazon.com/gp/product/B00YOJ91YO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 )
The main reason I am writing this is to alert others who are looking at buying this monitor. If you do pull the trigger and want to experience what the monitor can REALLY do make sure you have enough horsepower. Like I said a GTX 980 will power this bad boy, just don't expect 60fps or more in native resolution (3440x1440), Just think of all the monitor thats being wasted when you do, do that. With all that said it is your money and you can do what you want with it, I am just trying to help out my fellow gamers. You can also look up what I am saying on google and look at the difference 3440x1440 is compared to standard 2560x1440. It'll blow your mind!

*PS* I'm sure SLI'd 980's will give you what you want out of this. I'm not sure about 970's tho just look em up! Sorry to you AMD users, I don't really keep up with them.

Here are my PC Specs just so people don't think this monitor cost more than my actual computer..lol
i7-5920k 3.3hz OC'd to 4.0hz
32GB DDR4 2133 Quad channel G. Skill RAM
850w PSU
2TB HDD + 504GB SSD
Zotac GTX 980Ti AMP EXTREME 6GB GPU (New)
I originally had the reference GTX980 in there.

This monitor is very nice and well put together. I was hesitant on buying a free sync monitor to pair with my GTX 1080 but this has been a dream. NO tearing and really crisp colors. This would have easily been a 5 star review had it not been for the amount of light bleed that this monitor had. I am currently in the process of exchanging for another monitor and will update the review with a new score based on the new monitor. I like the USB hub on the back of the monitor and the ambient light os a nice touch. Really a great monitor for your money but if you're like me, be picky about light bleed on a $600 monitor.

I've had this monitor for just at a week now and I am impressed. It showed up with no damages or dead pixels and a lot of protective wrap to ensure those 2 things happened. 21:9 is beautiful and this monitor does it very well from what I have seen. Of course, not every game plays in 2560x1080 and some require tweaks but that's what the internet is for and if you're here reading this then you can do a quick search too.

Quality of the anti-glare is ridiculous, I have a fan with the lights in it and in the past I've had to game/watch media like a cave man in the dark but this thing doesn't pick up any light. Colors look solid out of the box (for my taste, your mileage may vary). The joystick took all of 2 minutes to get used to so don't let that be a deterrent.

All in all I would say if you want to go Ultrawide like I did on a budget or just don't know if you will like the experience then this is the monitor for you. Especially if you're running an AMD Freesync capable card.

This is a Fantastic monitor. Gsync is incredible and the colors on this monitor are out of this world. My only complaint is that whenever you update the video drivers on your PC i have to re-color the monitor every time, but that could just be an error I am making. Strongly recommend this if you don't want to shell out for 4k

Excellent monitor. The clarity is amazing. To achieve full 2560 x 1440 resolution, be sure your video card supports this resolution and you use the DVI dual link or DisplayPort cable(s) that come with the monitor. My understanding is HDMI will not support 2560 x 1440. I've had the monitor about 2 weeks and had no high pitched sound issues I've read in other reviews. I would definitely buy this monitor again.

I love this monitor, I do my gaming and graphic design work on it and the graphics look crisp and clean. The 23in is a perfect size. And the monitor looks nice in person! I get a lot of compliments on it!

So I was wanting to upgrade from my 23" HP w2338h (LOVED the glossy screen on it, so I was hesitant on going to matte), and was reading reviews and all for 2 weeks. This monitor kept popping up in that 4/5 range on Newegg, Amazon and in a 3.5 on Cnet, with still much positive things to say. I had credit to burn, so I'd pay a lot less out of pocket, so I bit and got $4 one day shipping. In a little over 24 hours, I had this at my doorstep, and opened it-- It truly felt like Christmas in July!

First impressions: Whoa. 27 inches doesn't seem like that much after having a 23" for 2 years, but man, does it really make a difference in your face. Setup was simple; a CAVEMAN could do it! After setting up the 3D vision 1 (yes, this is 2011 model, so now Vision 2 or Lightboost; the HN274HB is out in Germany, but not in US, and no expected date) and calibrating and adjusting RGB and brightness (BRIGHT monitor!), I got right into testing it with Cyberlink DVD 11 and using Tekken Blood Vengeance. REALLY good 3D effects! I plan to watch a few Pixar and animation movies this week to see in 3D, but the REAL shine is the gaming.

I'm not one of those, "I game a lot, it's amazing for gamers" guy-- I don't say I'm a gamer, I show it: I own 268 games on Steam (2012 Summer sale is KILLING ME!!!), Steam rating of 10 constantly, and game from FPS, Fighting, Strategy, etc. I can GUARANTEE you as a die-hard PC gamer with stats to prove, that you will love this monitor for 3D gaming. The games I tried were Super Street Fighter IV: Arcade Edition (5/5 3D Vision rating, and is BEAUTIFUL), Batman Arkham City (5/5 3D VIsion rating, THE BEST looking 3D in sense of depth) and Max Payne 3 (5/5 3D Vision ready on website, "Not recommended on monitor settings; I guess they port over ratings as a HUD on the bottom right whenever you boot a game in 3D) which looks really good.

If you're looking for a quick fix into 3D, don't hesitate to buy this. Beautiful bezel, great screen and resolution sharpness, great 3D with VERY little to no ghosting (Read that adjusting brightness and RGB will minimize it to practically none)and the use of an embedded IR emitter, along with every cord you need makes this the best 3D monitor choice on the market.

If you CAN wait (And I will do my research about release date of it within the return period, ONLY to return if a date is announced soon to get the newer model), there's a newer model of this monitor, called the HN274HB that is practically the same, but uses Vision 2 glasses (bigger glasses, more comfortable) and the LightBoost tech (enhances 3D to have the effect, but without the dimming picture).

Highly recommended!
