    All around excellent monitor with some (ignorable) gripes
    Coming from being a TV gamer the past several years, I don't have the largest frame of reference for gaming monitors, but I do try and keep up with the latest tech. I jumped on this monitor because I wanted a few things.1. Excellent dark room performance2. 1440p Ultrawide Resolution3. Fast gaming performanceIt didn't disappoint me. The colors are phenomenal as advertised and I for one believe 1440p ultrawide to be the quintessential gaming resolution for the foreseeable future. Dark room performance is great, I have toned down the brightness quite a bit though and I'm not real sold on HDR. Gaming is super fast, and this along with the color saturation, really make for an impressive step up from my TV. I can't give the monitor a full 5 stars, though, because there is still some ghosting, although it is minor and doesn't affect gameplay, only my staunch reverence to plasma displays. The panel uniformity is a bit disappointing too, as you can see in the first picture. The picture is a bit saturated and uniformity is not as bad as it appears. I'm not planning to use this for movies much, but if I were, that would be a reason not to consider something else. I have no dead pixels currently which is always a huge plus for panel quality. Overall, I think I will have this monitor a long time, assuming someone doesn't make an ultrawide, 1440p, OLED that is affordable. Plus, I got it for $599. I would have killed for something like this back in the 2004. What a time to be a gamer.

      I connected this monitor to my 16in MacBook Pro using a USB-C to Displayport adaptor. Monitor immediately came on and started working as an extended desktop. Was able to go into settings and select screen ratio and Hz settings. A USB-C connection would have been handy, but oh well.

      I had been using dual 24in Apple Cinema Displays for my home setup, and had placed them at an angle with each other. This single 34in display is awesome as a replacement for dual screens. And the Curve is great..as mentioned I already had to angle dual flat screens, so the curve concept made sense.

      I'm not a gamer (yet) and don't necessarily stress out graphics in my daily use. But it looks great, connects easy and I am very pleased. Assuming all of Cooler Master's specs are true, this thing was the best price/spec combo available and will be able to do anything I need a monitor to do, and do it well. I just hope my gaming kids don't take it because doesn't seem there is much availability of this monitor just yet if I have to buy another :)

      Got this monitor in about a week ago. Easy setup with the base. You would just need a screwdriver for the 2 screws. Been using it almost every day and I've had no problems whatsoever. 144hz runs great on all fps games I play including Overwatch and Apex Legends. Definitely satisfied with my purchase! I'm glad I ran into this while it was still in stock considering it was one of the only 144hz 1440p monitors left in stock anywhere. Great price for a great monitor.

      After playing Skyrim on this monitor for a couple of days I'm not sure how I ever played without it! The picture quality is fantastic and framerate is excellent. I've never had a curved monitor before, and the field of view allowed with a curved screen definitely makes a difference.
      The monitor was really easy to set up and the adjustable stand with tilt makes it very ergonomical. The sound quality is pretty standard, but not bad at all. For the price I don't think you can beat this monitor.

      Verified PurchaseEarly Reviewer Rewards(What's this?)
      I had a 27 inch 1440p IPS that worked fine, but every time I glanced at the TV I couldn't help but envy the contrast on the other screen. I figured I've been playing on this monitor for 5 years so a monitor upgrade to go along with a PC upgrade was reasonable.

      I decided to go 21:9 this time around for a more immersive experience. I also wanted to go VA for the contrast. I know it has worse viewing angles, but I was the only one staring at the monitor 99% of the time anyways.

      I've only used it for about 2 days so far but it's been amazing. I hooked it up to my monitor arm because it's 75mm Vesa compatible so I can't speak to how the stand works.

      I used the calibration settings recommended on TFTCentral and it looks amazing. I also checked out a monitor testing site and as far as I can tell mine came with no dead pixels.

      I set the settings to fast overdrive to reduce smearing without introducing overshoot (fastest might introduce overshoot) and also enabled Gsync trough the Nvidia Panel Settings. Played a few games of Rocket League and Mortal Kombat 11 and it's just amazing MK11 in particular has darker visuals so the added contrast and Quantom Dot colors make for an amazing experience. You also get to see more of the stage at once, just wish I could turn off the HUD for when I play locally. I also didn't noticed any smearing. This could be because I'm not predisposed to noticing it and because VA panels have gotten much better over the years

      The OSD takes a little while to get used the and the speakers aren't great (monitor speakers never are). As I mentioned before, the viewing angles make it look washed out if you aren't positioned in front of it, so a monitor arm helps with aligning it to your specific height.

      Movies look amazing on it too, especially when they fill up the whole screen.

      I'll update my review in case something goes wrong with it, and if so I hope the 2 year warranty covers it. For now, I'm very happy with it.

      This panel is very pretty and amazing for the price. The response is quick, nearly no ghosting. The colors pop, an good gosh the difference between the blacks to white. My eyes have to adjust every time I switch between something with a white background, like a web browser to something different. In gaming the HDR is noticeable and the colors are superb. 144 refresh rate, curved, and ultrawide goodness.
