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. 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. It would have been nice to see the traditional USB-A ports be 3.0 instead of 2.0, but I suppose if you’re looking to optimize speeds, you’ll just use the TB3 port and supported drives and other accessories.
The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage. Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches. There are two main categories for curved monitors: those built for gamers, and those designed with business professionals in mind. But what if you want the best of both worlds? A monitor with a fast refresh rate, low input lag, fast response time, good viewing angles and fantastic colour reproduction? Step forward the C34J79, a 100Hz curved gaming monitor that combines Samsung’s quantum dot technology with gamer-friendly VA panel technology. 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. that violates any law, statute, ordinance or regulation (including, but not limited to, those governing export control, consumer protection, unfair competition, anti-discrimination or false advertising);
The 21:9 ratio resolution is also known as Ultra Wide Quad High Definition (UWQHD), or the wide brother of the 2560 by 1440 QHD that was at the top of the HD food chain for several years before 4K UHD (3840 by 2160), 4K (4098 by 2160), and Apple’s 16:9 4K (4098 by 2304) showed up. Now you also have Apple’s 5K display on the iMac (16:9, 5120 by 2880) and upcoming 6K Pro Display XDR (16:9, 6016 by 3384—if you have a 5K iMac or plan to get the Pro Display XDR, you’re not really in the market for a CJ791. If you’re using a MacBook or Mac mini, then it’s a worthy option. 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. I found the CJ791 to be quite comfortable to use, but then again I don’t experience any eyestrain when using my 15-inch MacBook Pro.
Information about the average amount of time, in which the pixels change from one color to another. There’s also Picture-in-Picture and Picture-by-Picture modes, which could be useful for some use cases. Here’s how the two features work: 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. 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.Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.
The storage temperature shows the range from a minimum to a maximum temperature, within which storing of the display is considered to be safe. 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 Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.Information about whether the stand can be dismounted. Usually, this is required for wall mounting. Dimensions, weight and color Information about the dimensions and the weight of the specific model with and without stand as well as the colors, in which it is offered to the market. Width
The Samsung CJ791 is simple and fast to set up. The power cable and the Thunderbolt 3 cable will get you up and running with any modern MacBook Pro, MacBook Air, or MacBook. Picture-by-Picture (PBP) lets you display to two sources onscreen at their native resolution. Optimize your multi-tasking further with Picture-in-Picture (PIP), which lets you resize the second source to up to 25% of the screen and position it anywhere. 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.Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases. Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality.
