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.

Can't beat it for the price. Picture quality is very good, reaches the advertised refresh rate, and 1440p is just so nice to look at.

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!!!

You can't expect something perfect at this price point when considering specs. But the only downside I have noticed is the color quality is overly washed out. Only truly affects those in digital art. The image is crisp. It does support 144hz, and it is 1440p. The backlighting died in my Acer 27", and after looking at the horror stories from people trying to get Acer to repair it, I just decided to give this a try. The build quality is much more superior to Acer. Every Acer I have owned has felt like a cheap flimsy piece of plastic. It hits all the marks where it matters. And at the price point you can't beat it. Just set expectations that you are not buying a $700 or more monitor. To fix the color issues, I used my graphics cards utility to correct the color issues. Monitor looks just as good as my more expensive monitors now.

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.

I've had this monitor for like 8 months and am still blown away by how well it works. 0 issues, so far. This monitor was for my first ever gaming PC I built. Super small text or graphically contrast content may have visible pixels, but in general gaming I don't notice or really care. It's cheap, the refresh rate and image quality is incredible. It's not the most lustrous image quality, but I'm still genuinely impressed how well it handles deep rich black tones, which IMO cheap monitors usually fumble.

This review might be long overdue but for some reason I can't seem to get the monitor to reach 1440p with 144hz. I can reach it if I lower the resolution to 1080p. Hopefully there's a fix to this.
