KOORUI 27-inch Gaming Monitor 144Hz QHD(2560 x 1440p) 2K, 1ms, DCI-P3 90% Color Gamut, Adaptive G-Sync, FreeSync Premium, HDMI x 2, DisplayPort, Black, 27E1QA

I bought two of these and they’ve been great. The size is enough for what I need, the quality is good enough, and I bought them for a fair price.One of them is sometimes blinking on and off but I suspect the issue is my HDMI cable and not the monitor itself. Once I replace it, and if I remember to, I’ll update this review to properly reflect that.

After reading a bunch of reviews I finally pulled the trigger and picked up a pair. I was happy with how they were packed showed up in great condition.Setting them up wasn't difficult either 6 philpshead screws to put the feet together (not in pictures due to the new mount I got) tilt on the stands were good enough but with it the side to side adjustment the feet were kinda in the way but sturdy.If you use HDMI to connect you'll have 144hz but if you use Deplay port cables the monitors are capable of 165hz which was a surprise.Over all since September 2nd when they got here to now both of these monitors are going strong and I haven't seen any of the screen tear or other issues I seen others having.Of you're unsure about this monitor don't be. But be warned 2 27 inch monitors need more room than you might think lol.

As a note to new buyers: a chemical-like odor may be emitted from your monitor's exhaust for the first 2-3 weeks--at least mine did. I did some research and this was likely attributed to some cleaning chemicals from the factory, and it is burning off from the heat of the monitor. Simply have good ventilation in your room, and the odor should dissipate in 2-3 weeks. I've had this monitor for over a year now, and there is no odor anymore.Now, for the actual review: This monitor is great quality for the price! Not perfect, as I've found this monitor doesn't display smooth gradients of dark very well. For example, when I'm in a dark room in a video game, the dark ambient colors show slightly pixelated rather than smoothly blended.Other than that, this monitor works like a charm! Colors are great, and monitor settings are easily adjustable. One complaint I have is that I can't change the monitor's brightness using the Windows OS' brightness settings--you have to change the brightness/contrast using the monitor's buttons.

Very Happy great monitor for the price!!!

I've used 4 of these at one of my clients and they love them! No problems at all so far. The higher resolution 2560x1440 these have make a very big difference when using them for work. These monitors are great for owners of Dell business model computers like the OptiPlex & Precision lines that normally have DisplayPort video ports. They include only a DisplayPort cable, so if you need HDMI keep in mind that you'll need to buy the cable separately. If you own a Dell, then you can use it right out of the box with the included DisplayPort cable.Always pay careful attention to the resolutions of bigger screens! There are a LOT of less expensive 27" or larger screens out there that have lower resolutions. Don't fall for the "but they're 27", they're all the same" line of thinking. Getting the higher resolutions really do make a difference. Imagine getting an extra 10 columns showing on a spreadsheet, or pulling up a calendar and seeing the whole month on the screen at once.The way I describe it to my clients... the lower resolution 27" screens are like taking a 19" screen and just stretching it out... its bigger, but not better. Like sitting very close to a TV screen, bigger isn't better when you are 2' from it at low resolution. Always get at least 2560x1440 resolution on anything bigger than 23", it's worth every penny if you have to sit in front of it all day for work!

If I could give this monitor 0 stars, I would. I really don't have high expectations for a monitor. I hardly care about video quality, refresh rate, etc etc. However, this is such an unusable, frustrating pile of garbage.The monitor often fails to even allow the user to the menu options, and once the menu is open, is difficult to transition between the desired inputs. God forbid you click the wrong input, in which case it'll bug out and the screen will flicker around, incapable of figuring out what is happening. I've seen computer monitors in the early 2000s with better functionality than this.I have had such a lousy experience with these monitors. I have no clue how this was rated so highly. Strongly regret buying this.

Update: I ordered a second one of this monitor to match the first, but it came with an inner screen crack (You will only see it when the monitor is on, as it affects the pixels) along the top-center of the screen. I was able to return the product and receive a full refund, and will likely reorder this product in hopes of getting one that isn't cracked.Review (5 stars):This is a 1440p monitor with 144hz and 1ms, just as it says.The setup isn't difficult, but my package didn't come with any clear instructions. There are 2 pieces that attach to the base, both need 3 screws (included in package). Then, you snap the base to the back of the monitor, it can be a little tricky if it is your first time, so keep trying and don't get frustrated.Note: If you intend to use an HDMI cable, you will need an HDMI 2.0 cable (Amazon has an Amazon basics HDMI 2.0 cable which doesn't cost too much) and that cable will need to be plugged in the 2nd HDMI port, as the 1st port is for HDMI 1.4 which doesn't support 1440p 144hz. Also, if this is for a PC, you will have to set the resolution and hz for this monitor in ur OS settings (for me, I used Windows 10). Your graphics card may also need to have it's settings adapted for the monitor depending on it's default settings.Overall, very good monitor. Got it for $180, and that was a very decent deal compared to other monitors of the same resolution, response time and hertz.
