The stand is beautifully engineered and provides both height and tilt adjustments, plus if you want to wall mount it you can use the VESA mounting kit included in the box. You might want to do that, as well, since in addition to its wide, 21:9 aspect ratio it’s a jolly big screen, measuring a substantial 34in across the diagonal; Samsung also introduces a dramatic 1500R curvature here, the idea being to provide a more immersive viewing experience than a flat monitor. Desktop monitors and smart TVs experience a latency/lag in visualizing the information. The time in milliseconds that the display needs to visualize the signal input. The CJ791 uses a matte, anti-glare screen coating that is less impressive at first glance that the glassy gloss of Apple’s displays, but it can be a real eye-saver in the long run. At the very least, it means you don’t have to be as careful as you do with Apple’s glossy displays about how you orient the CJ791 in glare-prone environments. Samsung
And then there’s the resolution, which hits the heights at a gloriously sharp 3,440 x 1,440 resolution, delivering an unquestionable advantage over cheaper 2,560 x 1,080 screens.

Update: The base of the stand can actually be opened up to fit the power cable and other cords that wouldn’t otherwise slide through. Thanks, Daniel! Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio. The peak brightness measured right around 300 nits. That’s a full 200 less than with many of Apple’s displays, though the contrast is adequate for most purposes. But between the LCD leakage and low peak brightness, you don’t get a particularly dramatic picture. Watching video and movies will be a ho-hum experience if you measure things purely by the display’s contribution. Bottom line
Specs
Overall, the Samsung CJ791 offers a lot to like: Thunderbolt 3 with 85W power delivery, a great ultra-wide 34-inch curved display, a sharp design, a nice amount of ports, generous height and tilt adjustability, and thoughtful touches like the built-in cable management. The percentage of the approximate area, taken by the active part of the screen, to the total front area. The upstream Thunderbolt 3 port for connecting your MacBook offers up to 85W charging, which is just 2W shy of the max 87W that Apple says its 15-inch MacBook Pro will accept. In real world use I don’t think anyone would notice the difference even when running a Mac hard. The second Thunderbolt 3 port is a downstream connection and can output 15W, nice for a fast iPhone or iPad charge in addition to being handy for TB3 peripherals.

There are two speakers on board, which is convenient for everyday work but not serious listening. There’s simply not enough air available for them to reproduce the entire audio spectrum—there’s no bass response. Quantum dotsInformation about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality. The Samsung CJ791 Ultra-Wide Monitor has a sharp look with a silver and white finish. The majority of the display is made up of a plastic body, but that doesn’t make it look or feel cheap. It has a slim quarter-inch (6.35mm) bezel on the top, left and right. The bottom of the display has an eighth-inch (3.175mm) bezel plus a silver chin that measures in at just over half an inch (13mm). The dynamic contrast shows the ratio between the brightest and the darkest color, which the display can reproduce over time, for example, in the course of playing a video. These are the readings when the CJ791 displays pure blue, green, and red images. Note that there’s not a lot of any other color present. Compare with the non-quantum dot readings below. This monitor uses a 5-way toggle style button to control everything from brightness, color profiles, switching inputs and more. It’s a bit clumsy to use, but you can also set up custom color profiles on your Mac in System Preferences.
