Very good qualoty

Ive had an Asus PA248Q for years and decided it was time to enjoy G-Sync. I was set on an Acer but kept going back and forth between the X34, XB271HU and XB321HK. After playing with an XB271HU in MicroCenter, I decided against 4k/60hz since the 144Hz made a huge difference in perceived motion. My XB271HU arrived from Amazon yesterday. The Mfr. date is March 2016. I have a monitor arm on my desk so I didnt try the included stand at all. Ive only played around in Rocket League and Crysis 2 so far (havent installed C3 yet) but the difference is stark in my eyes and Im really enjoying the fluidity. I checked immediately for dead pixels and got worried when I saw a small black spot in the top-left, but I was able to scrape whatever it was off. Now the BLB...theres some in the corners, especially the bottom-right. Having dealt with it on my Asus though, I already understand the drawbacks of IPS panels and Im confident that I will not notice it in 95% of applications. I think people are really sensitive about BLB because they spend lots of $$$ and want perfection, but until OLED or something similar comes down in price, you have to try and focus on the positives. I know I can live with it and I dont think playing the return lottery is worth the trouble. It doesnt feel a lot bigger than my PA248Q, but thats possibly because the XB271HU has such a thin bezel? Regardless, the pixel density is awesome and makes everything seem sharper. I would prefer if it had a slight curve, since I find myself having to move my head a bit to read text in the corners, but the benefits hugely outweigh all the little things I dont love (like navigating the OSD...ugh). One G-Sync issue (or maybe just confusion on my part) is that Ive set v-sync off in the control panel, but it keeps re-enabling itself somehow. I suspect it happened when I went into my games that previously had it enabled, so now that Ive disabled it in the games, Im hoping I wont encounter it again. Back to Rocket League!

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.

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.

Lo pedi a colombia, vino perfecto, llevo 4 meses usandolo y la expencia con el es super buena, los herzios, la calidad de la imagen, el tamaño es perfecto y ademas tiene parlantes integrados lo cual no sabia, muy buen monitor.

This monitor is great, you have to turn on max brightness directly under super sharpness on the page below it which wont show up if you have certain things turned on so mess with the settings until max brightness pops up in the settings to get it to look good, other than that its a fantastic gaming monitor for 4k with great build quality and great picture and features, my only issue is that the crosshairs dont include a simple dot for motion sickness theyre all nice crosshairs but no dot does suck

So far, I am really liking this monitor. Despite a lot of reviews saying to avoid this montior I went ahead and got it because I have generally had very good luck with Acer monitors. All I can say is Im glad I went ahead and got this baby! The actual monitor looks amazing, the color scheme is very nice and it looks to be made with good quality care. Now Im not a color snob or anything of the likes but I do know a messed up montior when I see one and luckily for me, i got one that appears dang near perfect. I have next to no backlight bleed and no dead pixels. The colors look amazing and sharper even than my previous monitor, also an Acer, and its just so vibrant. The refresh rate is 144 out of the box as long as youre utilizing the DP cable that comes with it but it can also be OCd to 165hz. To be honest though, I dont really see the need to do that. But thats just my opinion on that matter. All in all, this a clean looking monitor that hits all of the points that I wanted/needed for my gaming setup. I would definitely recommend this montior with one caveat: not all monitors are created equally, so just be aware that you could potentially get a defective or faulty model. If that happens, definitely send it back for a replacement so that the makers of these high end monitors know that we, the consumer, arent taking anything less than perfection from their work.

Long time console/TV gamer. After researching specs I bought the XB283K to use with my Xbox SeriesX. Arrived in great shape, no dead pixels, stunning color, and decent brightness. Youll need to adjust settings on both the monitor and Xbox but the HDR looks amazing and is flawless at 120hz. The 28 screen was a nice transition from TV to monitor. I have been thoroughly enjoying the in depth experience and Im thrilled that I didnt over pay for a 32 Samsung G7, would definitely recommend to anyone who has a SeriesX and wants to game in 4K.

Though the monitor is awesome, it came with a Little bit of backlight bleed

I have had this monitor for 4+ weeks now. This is my initial pre-calibration review. I am getting an an X-Rite i1 Display Pro soon and after Ive gotten through the learning curve and calibrated it myself, Ill post a followup.(SEE END FOR FOLLOW-UP) I bought the XB271HU after patiently reading every monitor review for the past years or so. I have a GTX 1080 TI and have been running it on a Dell U2415 at 60Hz since the spring. I wanted a very good monitor that could work well for desktop and gaming since my machine is heavily used for both. I had been wanting a GSYNC IPS or VA 2560x1440 monitor in the 30-32 range so the desktop DPI issue didnt become an issue but there are are none as of the moment. This monitor was one of the most highly reviewed 27 so I decided to throw caution to the wind and give it a try. After 4 weeks, here is my pro/con list: If you have read the reviews, none of these are a surprise. Pros: - Excellent gsync monitor - 144/165Hz makes gaming fluid even with gsync off running a GTX 1080 TI - Love the light anti glare coating - Lots of screen real estate Cons: - UI is difficult to maneuver - Out of the box: Colors are washed out. Whites are dull. Blacks are grey-ish. Blacks are crushed - Yellowish tint obvious even when using commonly available ICC profiles from various review sites - For desktop use, its not nearly as nice as a quality desktop monitor but absolutely awesome as a gaming monitor The DPI of this monitor causes me eyestrain and Windows 10 scaling (even with the creators update) helps but does not make it good -- But thats not the monitors fault. The real estate is nice but I have to strain a little to see the small stuff. What is poor are the colors. I have tried a number of ICC profiles from review sites and none of them have resulted in what I would say are decent colors. Shadows are crushed to black and much detail is lost. Whites are not crisp. Well see how this all fairs after I calibrate it myself. So all in all, I it still earns a 5 because it is a gaming monitor and gaming at 144/165 fps is very pleasing. The DPI scaling doesnt present any problems with the games I play. Gaming with gsync and/or are high refresh rates is, as they say ,buttery smooth when you have your games tweaked for a 144/165 fps cap to match the monitor. --------------------------------------- EDIT 12/31/17 Follow-Up I received my X-rite i1 display pro and spent several days learning how to use it with the DisplayCal software. After calibration, the picture significantly improved. I calibrated to 6500k, 140 nit (my preferred brightness level). Whites are much whiter now. Colors improved and blacks and shadow detail got much better. My black level comes in at .16 and black crush in several of my games disappeared. Contrast level is still a bit anemic at 880:1 ---------------------------------------
