Install Flash Player The monitor is great when it works: This monitor is known to have a bad panel that Acer Refuses to fix: Within 2 years of purchase date G-Sync will cease to function correctly, causing a flashing black screen. Disabling G-Sync fixes the issue, but like many others here, I didnt pay $400 to not use G-Sync: Acer will not pay for you to ship the monitor to them, they will only pay to ship it back to you. I gave this monitor a good review, but that was under the assumption it was a working product and didnt have any design flaws. And here I wanted to buy 2 more of these monitors for a 3 monitor setup. Im so glad I didnt.

Great monitor if you get one that works. The one I received still has the Gsync bug from 2016 due to having falty/old firmware on the Gsync module. This is unacceptable as this was supposed to be fixed at least a year ago. Be aware when buying this monitor that the one you receive could have gsync issues.

Ive read tons of pros and cons of this monitor, and was a bit skeptical at first -- but in the end I just bought it and hoped for the best. Originally it was saying delivered, but when I got home from class it was missing -- thankfully I found out my roommate had brought it in for me and just placed it in an area I couldnt see it. Now, if youre coming from a TN panel youll probably not like this right off the bat, because youre so used to the washed out colors -- but once you adjust youll fall in love. I used the settings that someone posted on Reddit (which you can find by searching -> "Acer Predator XB271HU High Accuracy Calibration Settings (Nov 29, 2016)" with the quotation marks) and have no complaints. Youll have to also download and use an ICM profile, but these are the settings you can edit on your monitor that I used Option 2 OSD Settings (240 cd/m2): Picture: Acer eColor Management: User Brightness: 65 Contrast: 50 Blue Light: Off Dark Boost: Off Adaptive Contrast: 0 Color: Gamma: 2.2 Colour Temp: User R Gain: 99 G Gain: 99 B Gain: 98 sRGB Mode: OFF Saturate: 100 6-axis color: Default settings (50) Game Mode: ON Setting: Input: DP DTS: ON OD: Normal Wide Mode: Full Over Clock: ON, 165Hz ULMB: OFF Power LED: Auto off Deep Sleep: ON Information: Resolution: 2560x1440 Input: DP Max Refresh Rate: 165Hz Mode: G-SYNC Mode Game mode: Settings 1 (FYI you must save your custom settings to Settings 1 before using Settings 1)

With the release of the 1080 Ti and the onset of (semi) affordable single-GPU 4K gaming, I decided it was time to take the plunge into the pixel-dense future. I debated going with a 1440p 144 Hz model, but having experienced 60 Hz 1440p, I decided I preferred higher sharpness over increased smoothness - especially given that my games of choice are slower RPGs and action/adventure games. If I were into twitchier fare such as Battlefield 1 or CS:GO, then this monitor likely wouldnt be as good of a choice. That said, even at 60 Hz, its gaming chops are solid with very low lag and excellent color reproduction thanks to IPS. And, as described below, the inclusion of G-sync is a game changer. The gaming experience at 4K is, in a word, stunning, especially when coupled with a smooth and fluid 60 fps performance provided by a 1080 Ti (or similarly high-end card). Everything is noticeably sharper and more detailed, and I even found myself noticing little things I hadnt before - e.g., wrinkles on Geralts face and texture fabrics in the Witcher 3, as one example. The downside is only recent games have been designed with this resolution in mind, so texture detail and UI scaling may not be ideal in older games. That said, with so many pixels at your disposal, dropping to a lower resolution in-game and letting the monitor upscale the image works decently enough too in a pinch. Of course, gaming at 4K is a workout for any system, even with the 1080 Ti, so the inclusion of G-sync on this monitor is a smart addition for the current limits of 4K gaming. Barring drops to medium settings, most current games will run anywhere from the mid 40 fps range up to 65-70 fps, so G-sync allows you to crank settings to high/ultra and not have to worry about maintaining a locked 60 fps. Without the ugliness of screen tearing or stuttering, everything just feels smoother and more fluid, even when fps arent holding completely steady. A fantastic addition to the monitor that makes gaming a lot easier to dive into without having to constantly tweak settings. One tip I discovered, though - G-sync works specifically for when your GPU is outputting *below* the 60 Hz native refresh of the monitor, but when outputting *above* 60 Hz youre still subject to tearing and stuttering, as I discovered when initially I only enabled G-sync itself in the Nvidia control panel. Instead, G-sync is designed to work in combination with a V-sync solution (whether in-game or via Nvidia control panel) in order to provide a completely smooth experience. Once I enabled *both* G-sync and V-sync in the Nvidia control panel, everything was buttery smooth. This likely isnt an issue on 144+ Hz monitors, but since youll be fluctuating above and below 60 fps on this monitor, its a must. Besides gaming, this monitor works very well for general desktop use and productivity, although with the recommended 150% UI scaling in Windows you wind up with identical workspace to a native 1440p monitor (which I think works very well for this size). Unfortunately, while UI scaling is improving its still not as robust as on Mac computers, so be prepared for small bits of wonkiness. Ill also say I was a little ambivalent about the gamer aesthetic of this monitor, but its growing on me over time. I just wish I could get rid of the Predator logo on the front bezel.

PROS of XB271HU • The stand was easy to setup, it feels high quality and moves smoothly. The vertical adjustment was stunningly useful. • 1440p//IPS are a night-and-day difference over my previous use of 1080p//TN panels. • IPS bleeding is minimal. The top-right corner of my screen is most affected, but its not easy to see. CONS of XB271HU • At random intervals, the monitor "displaces" a line of pixels from the center of the screen, displaying them on the right edge. • ACER support says this problem can be sent in for repair. But it feels stupid having to pay $60 in shipping to firmware update a NEW monitor. • Feels extra stupid because this problem was discovered 2-years before my purchase. • This bug occurs once or twice per 10 hours, and goes away if you power-cycle the screen. • At other times, Ive noticed a split-second graphical disturbance about 1" long in the center of the screen. CONCLUSION • The bugs are minor. But small bugs are hard to swallow on a top-shelf monitor. • Overall happy with my purchase, but cant give 5-stars to a bug-riddled product.

Edit: My first unit had a patch of backlight bleed in the top left which was super noticeable, so I returned it. My second doesnt have any blb, but unfortunately it has 3 dead pixels in the lower left of the panel. Not sure if this is indicative of the current batch of these monitors, or if I just got unlucky. Will likely return this second unit as well, as for this price I really dont want to have any panel defects. This is a fantastic 4k high refresh monitor. It has a fairly subdued look other than the the LED lighting on the bottom and back of the monitor, which can be disabled if you choose. When enabled, I think that it provides a nice amount of bias lighting. This monitor offers very good sdr performance out of the box. By default, the wide color gamut is enabled. The monitor offers an effective sRGB emulation mode however, which is a welcome feature. Often panels with a wide color gamut dont have the ability to limit the gamut in typical sdr use like on the desktop, which results in over saturated colors. Having the sRGB mode eliminates this. With my i1 display pro colorimeter, I measured an average DeltaE of under 1.0, with a maximum of 2.3. Native color temperature is 6700k, which is what Acer actually calibrates these to at the factory. Native contrast ratio of my unit is 1065:1, which is typical for an IPS panel. Gamma was slightly off, as it was too high on the low end (making near dark tones too bright) and slightly too low at the high end (making brighter values too dark). Of course after full calibration using the colorimeter and DisplayCal, the performance is exceptional, with perfect gamma, deltaE values below 0.5, and 6500k color temp. The SDR variable backlight in the OSD is enabled by default. From my testing, it seems to enable a crude form of local dimming- only 3 or 4 zones. In practice it doesnt really do much of anything, I saw improvements to contrast ratio of only <50, which is barely noticeable. The good news is that you cant really notice it in practice. I think its subjective whether you want to have this enabled or not. The HDR performance of this panel is actually pretty surprising. Its only certified hdr400, but the image quality is much better than other hdr400 level monitors Ive used to this point. The color accuracy in HDR is excellent and is just as good as in SDR, and tone mapping is done quite well. I found that games with good HDR implementation look amazing on this monitor, with the weakness being that dark areas are really not that dark. Since this panel does not have full array local dimming, dark areas will never be very dark, but the way this panel tone maps HDR content makes the image appear much higher contrast than in SDR. Bright, outdoor scenes especially look amazing. Whether or not the extra $600 for full array local dimming on the X27 is worth it is debateable, as the local dimming does cause haloing around white objects on a dark scene. Suffice to say though, for most users the HDR performance provides a nice boost on games and videos. Ive shown a few example pictures in this review. The fan is not very noticeable in my setup. The sound of my air cooler in my PC drowns it out. Just be aware though that this monitor does have a cooling fan that does ramp up when using HDR. Due to the gsync HDR chip, hdr and gsync can be used at the same time. For full 10 bit color, you will need to limit the refresh to 98hz. Since most games struggle to go above 98 fps at 4k even on a 2080 or 2080ti, this isnt a huge problem. You can also choose to run it at 120hz, which will limit you to 8 bit. In practice I couldnt tell a difference between the two. If you overclock to 144hz, it will enable chroma subsampling, so I dont recommend it. Im using a 2080, and I can easily get 60+ fps in newer titles by just turning down a few settings. I tried games like division 2, BF V, AC Odyssey and Shadow of the Tomb Raider in 4k HDR and they were quite amazing, and I was able to get over 60 fps without too much trouble. Since it also has gsync, fluctuations in fps are smooth. Also, most newer games have resolution scaling and such that will allow you to adjust down and reach higher fps, which is beneficial in competitive games and such. In short, its an excellent high refresh gaming monitor. I took one star away because of two issues my unit has. First, there is a bright spot of what appears to be backlight bleed at the top left of my panel. Its noticeable on a black screen or in dark scenes in games, enough that its bothering me. The rest of the panel however is very good, and the IPS glow is on the lower end in comparison to other IPS panels Ive used. The second issue is two dead pixels in the lower left of the monitor. Honestly, the pixels are so small that its in no way noticeable during normal use, and can only be scene when looking for it (i.e. in a dead pixel test screen). For a $1200 monitor however, these two issues are enough for me to want to try an exchange. Overall though, this is a fantastic panel packed full of gaming features. At about $600 less than the X27, I think this monitor offers better value for the money, even though its still very expensive. HDR content is still limited really, and these 4k high refresh panels are still limited by display port 1.4, so HDR is still not fully mature on monitors. I think this panel does HDR "good enough" for current standards. It will not match a good 4k HDR TV, but you also wont find a TV with 4k high refresh and gsync.

If you have a 2080ti and are in the market for a 4k monitor this monitor is absolutely gorgeous. I really dont understand the complaints of backlight bleeding from the AMD sister of this the XV273K but I see no backlight bleed at all on this panel even at max nits. I have seen the price fluctuate and some sales on this monitor so if the current price of $1249 is a bit steep maybe a price drop will occur in the near future but I absolutely think this monitor is worth the price. Stunning.

So, I had been holding off on buying this monitor for a few years now, but when Amazon briefly lowered the price to $699 I went ahead and pulled the trigger. I had previously bought the excellent 28" 4K Acer XB280HK about 4 years ago, and while I have been very happy with it, over time there are three things which have become very clear to me: 1. 28" (and certainly 27") is too small for 4K resolution. All the wonderful finer artistic detail that game developers spend so much time putting into their games gets lost because its just too small at 4K on a 28" screen. Scaling helps a little, but you end up using allot of GPU for little gain. 2. 30" to 31" is probably the sweet spot for 4K monitors IMHO...but larger then that starts to extend past your natural peripheral vision so that you either have to move your neck to view all of the screen, or set the monitor further back, in which case see item #1. 3. The narrower viewing angle found on the TN panel of my previous Acer didnt bother me...until I went back and used my older IPS panels. The TN had outstanding sharpness when viewed directly on, but its not as comfortable on the eyes and there is subtle overhead in staying properly positioned. At first glance the Acer Predator XB321HK seems to address all these concerns by virtue of being a 32" IPS panel. Unfortunately the historic cost of the screen wasnt consistent with the reviews. If you are going to plop down over >$1K then it should darn near be perfect, but at $699 I was willing to take a gamble instead of waiting for higher frequency versions which are almost certainly in the pipeline (and possibly the reason for the price reduction which suggests an attempt at lowering inventory). The two consistently reported issues with the monitor are IPS glow and occasional flicker. I didnt perform an "IPS Glow Test" because if I dont notice it under normal usage, then it doesnt really matter...and seeing it exist in a scenario which I dont naturally encounter would be a bit like that annoying sound you dont notice until someone points it out. Ill modify and update this review if I encounter the flicker...the box my XB321HK came in said that it was made in April of 2018, so my hope is that they have updated the firmware or otherwise modified the monitor to resolve the issue, but who knows? As of now the monitor seems to be precisely what I hoped for. UPDATE: After using this for months now I finally have encountered the "flicker". The frequency of occurrence seems to come and go....I wont see it happen at all after days of gaming and then Ill get a few every hour for a few hours. It also seems to occur in relation to certain major "transitions" in the monitor display, like going from a load screen to the next, rather then while Im actively using it. It seems kind of like that quick flicker you sometimes get when you change a monitors resolution. It hasnt been frequent enough to quite rise to the level of annoyance (yet....).

Install Flash Player Acer Predator XB241H bmipr 24-inch Full HD 1920x1080 NVIDIA G-Sync Display, 144Hz, 2 x 2w speakers, HDMI & DP Best monitor Ive ever had! The switch from 60hz was astonishing and I will never go back! I was skeptical about 144hz and didnt understand it even with watching dozens of Youtube comparison videos, but when I setup my monitor and played it for the first hour, I was amazed of how butter smooth the experience was. Pros: - 1080p with up to 180hz OC which is overkill, but nice on 1080p games that have no frame rate limit and paired with a strong GPU. - G-Sync which syncs your frame rate to the refresh rate of the monitor makes the experience on all games seamlessly smooth. - Bezels arent too thick and the stand is very sturdy with lots of articulation. I also love the slot in the stand which cables go through to have clean cable management. - No dead pixels on arrival or any other color bleeding. - Despite being a TN Panel, I was able to calibrate it to have vibrant enough colors for visually appealing experience, see my video and photos. Cons: - Stand is really wide and takes up desk space, would of liked a stand like the Asus ROG Swift. - Buttons arent labeled and you might accidentally hit the input button which if you plugged both the DP and HDMI port in will switch to one another. Would of been nice to have indicators on the buttons. - Color calibration was a pain and theres a dozens of forums on the net of settings so its hard to find the best one unless you want to spend an hour calibrating it yourself to your liking.

Works very well, thanx! 8/8/2017: When I first received this product it worked great. Since JUN 27TH, 7:21PM after owning the product I have had an issue with the aspect ratio. The screen pixels will not line up, half of them will be raised and the other half lowered. Also about a 4mm with the strip is removed from the center of the screen vertically and is generated on the far right side of the screen vertically. No matter how many times I restart the screen this will not go away. The only solution I have found is to change the Aspect Ration from either 1:1 to Aspect or Aspect to 1:1 the opposite setting. Normally I would not care about a simple issue like this however, it seems to be happening more frequently(at least once every three days).
