Great monitor - good resolution, easy on the eyes, and just that extra sideways space that's super helpful. Half price of similar others, was sceptical but happy I have it a shot (and the size is just right) NOTE: MAC: On MacBook Pro the HDMI connector doesn't support this high a resolution and looks weird when you first connect it. You have two options: a) can make HDMI support it but need to take it down from 60hz refresh rate to 30hz: need to install custom software that modifies the built in resolutions, or b) give up on HDMI and go to usbc (much more built in support.. so put the lower res monitor on hdmi) NOTE: VESA: my VESA mount didn't fit and had to be filed down - after that it was able to connect. And if you hook up vesa with regular screws the decorative piece doesn't fit anymore. went back to included stand and it's fine.

What a great product! Very easy to set up. The resolution is impeccable. I’m able to have several open workspaces. There is plenty of space for 4-5 large workspaces side by side if you need to work in different programs. I would purchase this again.

I got this on sale and was a bit nervous at the low price, but other reviews were good so I jumped on it. It was easy to set up, came VERY well packed, and they threw in a free hat. I use this as a multipurpose monitor. I do game with it, and appreciate the wide screen and HDR support. I also stream movies and again, works fine. as a work monitor I appreciate the curvature isn't as extreme as others, but scrolling quickly through things I do notice some motion blur. The red light on the back really isn't visible so it seems a bit of a waste. I've not tested internal speakers so I cannot comment on that. Its very sturdy and was easy to assemble

[Update 01/27/2024] Sadly, "so far" isn't good enough... After creating a shipping label, I turned to wrap my item and when I turned back my fancy-dancy Ultrawide monitor was dead. Powering off/on, a Mac restart, switching input, and trying the on-screen menu all resulted in the same blank screen. The monitor was powering on and the backlight was working, just nothing on the actual screen. A conversation with Amazon support agreed that the monitor was dead. Fortunately, I was still 5 days within the return period, so it's going back for a full refund. This was a magnificent monitor while it was working, good color, very readable text, and acres of screen real estate. However I won't be replacing it with another Deco Gear monitor. I just have no faith that it will last the distance. Back to "only" a 32" monitor... [Original review] I was looking for more screen space and this seemed like a potential solution, significantly cheaper than an equivalent LG display, although I had qualms about a brand name I'd never heard of and a display with no reviews. So far it's working out well. My MacBook Pro recognized the display quickly via the supplied USB-C cable and is running it at 5120x2160 and 75Hz. The colors look good and text is crisp and easily readable. The curve is just enough to make the edges that little bit closer and the Vesa mount connected to my existing stand with no issues. (I did not try the included stand.) The downward facing connectors don't give me any issues. Overall, I've quite happy with this display.

If you need 4k, but ultra wide 5120x2160, you have very few options and none of them are OLED. This model is by far the cheapest, uniform brightness, and supports freesync and 75 Hertz refresh rate... You'll have to spend at least double to get a Dell model with 120hz support, if not triple. This is bare bones, but does the job, has decent speakers in a pinch and supports USBC. Stand is sturdy and height adjustable... If you don't have space for three 32-in 4K monitors, get this and place it next to a single 32 inch. It supports splitting the screen in half, 2560x2160, which is nice. It's no the best contrast, and looks average off angle, but for the price, it's a steal.
