Acer Predator XB283K KVbmiipruzx 28 UHD 3840 x 2160 Agile-Splendor IPS PC & Console Gaming Monitor | AMD FreeSync Premium/G-SYNC Compatible | 144Hz | 1ms | 1xUSB Type-C, 1xDP 1.4, 2xHDMI 2.1 & 4xUSB

Yea i got these around $272, finished my triple monitor sim rig and I forgot how amazing ips panels can be, i have had one since it was release way back when and it still works fantastic. ULMB made these things great in gaming like fps, and the ips and gsync makes them great in more cinematic or all the prettys mode games.

Let me start out by saying that I do really like this monitor. I think that it has a lot of great things about it, however durability and quality wise in terms of life expectancy is terrible. If I were to buy a third one, within 3 years that would mean I would replace this monitor every year. Im not sure about everyone else here but paying baseline $500 dollars for a product that will not last me a year is borderline insanity. This is not a new issue either, both of them it started with a dead pixel and just escalated from there. One entire section of my other monitor has a very clear Red strip down the center of it. The current one that Im about to replace has 3 dead pixels and the last two were within the last couple of days. The first one was about 7 months in. I should not have this many problems with a monitor thats suppose to have good QC. This is very annoying to deal with and whats usually worse is dealing with Acers customer support. Every time Ive had to deal with the Acer customer support it leaves me wanting to tear my hair out because of the constantly transferring me to different departments, or the fact that I simply get hung up on every so often. Im just saying, for anyone who likes a good monitor but likes to replace it yearly. This is the monitor for you. And I will say this : I HAVE HAD NO ISSUES BESIDES THIS. The monitor is great, works fine, great picture, great response time literally no issues at all with it besides the fact that its life span is that of a chameleon. My advice? Still to buy it, but if you experience any issues like I have. Request your money back and take your money elsewhere like Im going to do.

Got this for my son for gaming and it blows away my much more expensive Samsung TV. Its amazing how much better the same game on the same console looks on this monitor.

Technically I’m rating this a 4.5/5, but I’m rounding up. Looks and runs fantastic on my Xbox series X and for college work. Tiny tiny bit of bleeding on corners on black screen but it’s really minimal (only shows when screen is fully black). Other than that, no complaints.

This is a fantastic gaming monitor. I had a ten year old Dell that was a great monitor for its time, but was getting old and the backlight was getting splotchy. I tried the PG268Q. It had an intolerable, absurd amount of vertical gamma shift. I had the BenQ XL2420G, which was good for its time, but is still small, 1080p, and washed out, dull TN color. Tried the XB270HU which was pretty good but had a little backlight bleed, so I returned it. Tried the XR341CK...even got an AMD video card!...and it was GORGEOUS, but 75hz is just too slow for gaming. Its even too slow for internet video, I realized. 75hz syncs with nothing and 2016 is not the time to be running a new headline PC monitor at 60hz. Got this and my search is over. Looked at the Asus, but my experience with their video cards and routers has turned me off. The quality control is gone, their products are garbage now. You can read the reviews of the PG279Q and see for yourself. This monitor though, is pixel perfect. Nothing dead or stuck. $800 is way too much to pay for a monitor with such pathetic problems. I have no, NO backlight bleed. There is some silvery IPS glow, but that seems to be inevitable with IPS panels now, which is odd because my 10 year old Dell didnt do that, apparently they used to use a filter to stop that, but it adds a lot to the cost so they dont do it anymore. Wish they did, Id definitely throw down another 100-200 for that filter. The color is great. I set mine to sRGB mode and turned the brightness down from 80 to 35 and Im pretty happy with it. I think the XR341CK had the edge on color, but this is a GAMING monitor, it needs the responsiveness too. Definitely beats out any TN panel all day long by a huge margin, though. The pixel transition time seems to be slightly better than the 270HU was, which is good, and the new bezel and stand are big improvements. The red stand looks better in person, and so does the bezel too. I have a big center channel speaker so the split foot is a welcome update. Quick tip, I run my desktop at 120hz, I believe it syncs better with 24hz and 30hz video that way. Run games at 144hz and use the MSI Afterburner software to cap FPS at 144hz to avoid having Vsync kick in, even at 144hz I find the added input lag of Vsync intolerable. Put 27 inches, good color, and 144hz without tearing together, and you have something that in BF4, CS:GO, and GTA Online (Im a sucker for the open world), is almost like cheating. Compared to a 24 inch TN panel I can easily tell the increased ability to see and shoot players online first, and it looks gorgeous to boot.

Acer makes great monitors, and the XB283K is no exception. If you dont care about HDR, then this is a great option for a gaming monitor right now. The factory calibration is superb, the adaptive overdrive settings create an experience with minimal blur and ghosting, and obviously a 4K picture with variable refresh up to 144 Hz can look spectacular. The one downside to this monitor is that the HDR performance is, put simply, barely above nonexistent. Yes, the color gamut is wider, but the edge-lit local dimming solution is almost useless to improve contrast and the 400 nits peak brightness rating matches my experience (calibration after a few days of use showed a peak of around 420 nits). Since its an IPS panel the native contrast isnt anywhere close to good enough for a good HDR experience, and the peak brightness will not impress anyone. With new miniLED and OLED monitors hitting the market, its only a matter of time before $500 - $600 will start getting you a significantly better HDR experience (I was able to pick up a used Sony Inzone M9 for $500, for example). The Cooler Master Tempest GP27Q/U have already raised the bar for what can be expected in HDR from <$1000 monitors, and its only going to get better from here. If you can stand to wait a few more months, I think better options will start to become available at this price, and the price of this monitor and others like it will go down even further.

Update (see original review below): Its been about 6 months since I got this monitor and I couldnt be happier. The minor backlight bleed I had originally is pretty much gone. Also, somehow the backlight has become slightly more neutral over time (went from 5800K to 6200K). Both seemed to change within the first month of use, but have improved and stabilized after that. Maybe it just needs a break-in period? Anyway, Im still loving this monitor, though it sounds like I did luck out with the panel lottery, since I have continued to read reviews about dead pixels etc. One thing I will say is pretty much none of these monitors will have perfect uniformity... in other words, if you have an all white screen, you may notice slight discoloration in some parts of the screen. Its definitely not something I notice unless Im looking for it. Some panels are worse than others in this regard. Original Review: After reading about all sorts of problems with IPS glow and backlight bleed, I thought I might have to skip this generation of G-Sync IPS monitors... but the XB271HU seemed to have more positive responses on forums so I decided to chance it. Either I lucked out, or Acer has done a better job with quality control for this monitor: no dead/stuck pixels, no massive backlight bleed, even backlight, etc. If anyone is wondering, I bought it on Dec 22nd and received one manufactured on October 2015. I tested the monitor using a colorimeter and HCFR to determine the best settings. By default, its way too bright (280cd/m2), so I bumped it down to 30 brightness (130cd/m2). Also, by default the whites are slightly off but not terribly so (about 5800K but greenish also). I set the RGB levels manually to 97-93-100. After those minor adjustments, my panel looks great! It even retains an excellent contrast ratio of 1100:1! As for backlight bleed, I think there might be a tiny amount, but I really have to look for it at my lower brightness setting. When I cranked the brightness up to 100, it was definitely visible. Whats more noticeable for me is the IPS glow. It seems to be worse than a regular IPS, because I can see it in the corners even while sitting in front of the monitor at a comfortable distance (2-3 feet). I am pretty sure it is IPS glow because it disappears if I move my head directly in front of an affected corner.

This monitor has amazing colors, clarity, response/frame rate. Its fantastic and a huge edge in gaming! The only issues are where the higher up executives got involved with the dumb RGB lighting design. The higher up out of touch executives must have told the engineers: it has to have RBG lighting. The engineers: okay? but where do we put the lights? Executives: it has to be visible. Put the lights on the chin of the monitor facing the user so they can see them Engineer: You sure it wouldnt look better if they were on the back and gave a glowing reflexed effect off the wall? Executive: no they have to be right in front of you facing your face so everyone knows its RGB. Engineer: ...Okay youre the boss. Acer, if youre gonna have RGB on your monitors dont shine the lights right in my face. This chin lighting bar is such poor taste and looks really bulky and ugly, and I wont be using it. Also stop putting built in speakers into your gaming monitors. gamers dont use them. You guys were so close to making a perfect monitor but you got lost in the sauce.

Pros: -Colors pop without over-saturation -Sharp -4K @ 144Hz -Quick response time Cons: -HDR implementation is one of the worst Ive experienced -Anything below HDR 600 is a waste of resources, this monitor uses HDR 400 -If you turn off HDR, the screen is actually quite bright. But once you turn HDR on, even at 418 nits, youll eventually have to crank your brightness settings via your GPU Overall: I use this monitor mainly for work now and light gaming. I have a RTX 4090 and its more than powerful enough to game at 4K, but even at 144Hz, the gaming experience just isnt as snappy. Plus the SDR color representation of this screen is so so. Its like they shouldve implemented HDR 600 to make it even worthy of a viable option to use. Other than that, the SDR experience for work productivity is fantastic. I do have buyers remorse though. This was quite pricey for a 4K monitor that knocks it out of the park with SDR but does very so so when flipping on HDR.
