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.

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 monitor is great for the price , however , it must be messed with as it doesn’t come out of the box looking great. The default setting for the monitor is pretty dull , after changing the monitor setting to “movie” and turning up gamma in Nvidia control panel it looks a little better. The HDR is nice, just seems like the colors are a little dull. For the price , pretty much a good deal with 2k , 1440P- and 170hz is a nice touch. The monitors performance is 10/10 , no flickering, black box, etc. Assembly is incredibly easy. Perfect monitor for gaming , 1ms response is ideal for most competitive FPS games.

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.

This was an excellent product for only $180 the graphics are excellent and the refresh rate is high. If you are skeptical, don't be because I was too and it came out amazing. The only bad thing about it was that you have to have a display port cable for free sync and my laptop didn't have it it's not noticeable. Don't look at the bad reviews they don't know what they're talking about unless you want perfect colors. The only thing was that there was just an unnoticeable amount of ghosting if you're playing if you run the ufo test you see a little bit. Also if you want to have QHD at 144hz plug it into HDMI port 2. Other than that It's a great monitor

I've had this monitor for about 2 months now. It worked fine, other than a little bit of ghosting when playing games. As of today there are small horizontal white lines going across the screen. I've reset the monitor settings, tried other cables (both display port and HDMI). I also tried with my other monitor and a tv, and both do not display the lines, so it is 100% an issue with the monitor. Going to see if I can get a repair or replacement through the manufacturer. I'll update if I get any results. Otherwise I would steer away from this monitor and company. UPDATE 8/27/2023: I submitted a support ticket through their website and received a response to my support ticket in late July, asking for images of the monitor issue as well as a screenshot of my order confirmation. I sent the images over, and haven't heard anything back in about a month. I just took a look at the email and it's coming from a general gmail account - which is concerning. There wasn't any crazy identifying information in the images I sent over, but it's VERY suspicious that the support email came from a general gmail account and not anything official. I also haven't heard anything back since sending the information. Needless to say, even more than before I'm very suspicious of this company and would recommend to stay away from their products, I'm at the point where I've written off this monitor as a loss and just got a different one from a reputable brand.

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.
