CJ791 Series - Ultra-Wide Monitor with Thunderbolt 3 for Business

Immerse yourself in the stunning visuals delivered by Samsung's CJ791 Series ultra-wide curved monitor. Empowered by Quantum Dot technology, the virtually bezel-less display supports 125% of the sRGB color gamut and is factory calibrated to ensure color consistency. Combined with the WQHD resolution and 3,000:1 contrast ratio, the monitor lets you enjoy breathtaking images with extremely crisp, natural color and rich details. Samsung CJ791 series also features two Tunderbot3 ports, allowing you to connect multiple monitors and peripherals at the same time.

34" Screen Size 3440 x 1440 Resolution 100Hz Refresh Rate 2 USB-C (Thunderbolt 3)
Thunderbolt 3 and DaisyChain Connectivity

This business monitor is equipped with two Thunderbolt 3 (TBT3) ports, providing a single cable connection for transmitting digital display, data (USB) and power. Connect your PC or mobile device with the USB-C port for an instant workstation. Plug peripherals in the monitor and work while charging your mobile device at up to 100W. Transfer data at up to 40Gbps and connect up to two monitors or six total devices, daisy chained, through a single compact port.1

Ultra-Curved Screen and Seamless Design

Samsung’s super curved VA panel is designed for comfort, productivity and style. With a 1500mm radius, the distance from screen to eye is a more uniform distance, resulting in less eye fatigue when working long hours. Wide viewing angles help to ensure the picture is not degraded from off angles. Plus, it sits in a sleek and seamless 3-sided virtually bezel-less frame, so you see more picture and less plastic.

Ultra-Wide 21:9 Aspect Ratio and WQHD Resolution

An ultra-wide 21:9 aspect ratio provides more room to work for enhanced productivity. WQHD resolution delivers twice the pixels and detail of Full HD resolution. Combined with a 3:000:1 contrast ratio, you get a vibrant, sharp picture so you never miss a detail.

Brilliant Color with QLED

This monitor supports up to 125% of the sRGB color space, 95% DCI and 1.07 billion colors thanks to Quantum Dot (QLED) technology. So you get exceptionally bright, crisp and natural reds and greens, plus smooth and seamless color transitions. Plus, every monitor is factory calibrated for color consistency.

Split-Screen (PBP) and Picture-in-Picture (PIP)

Connect up to two separate sources to the display and view them simultaneously with split-screen (PBP) and picture-in-picture (PIP) technology. Perform work, like coding, in one window and see the results in a separate window. With the included Samsung software, you can make window management easy and maximize your efficiency.

Fully Adjustable Stand and VESA Compatibility

The monitor swivels, tilts and is height-adjustable, to deliver comfort and ergonomics at work. And with VESA mount compatibility, installation on a wall or separate mounting arm is easy.

Easy on the Eyes

Eye Saver Mode and Flicker Free technology help to reduce eye strain for a more comfortable work experience, even during long work hours. When Eye Saver Mode is active, blue light levels are lowered. And flicker-free technology eliminates flickering at all levels of brightness.

Overall the monitor was a Failure! 7/24/2020 3:22:44 PM

Pros: It looks amazing and good on the eyes.

Cons: The monitor's internal speakers stopped working after three weeks considering the price point this should not be happening. Had to return the monitor back to Newegg.

Overall Review: I am loyal to Samsung but you need to Stay away for this one!

Sound? 5/13/2020 12:40:30 PM

Pros: Looks great!

Cons: Never figured out how to get the speakers to work. Trying to find information and updates takes you to corporate sites and everywhere but what you need.

Overall Review: Looks great, works well. Don’t expect help with it or for the speakers to work.

Outstanding Display 9/10/2018 12:26:17 PM

Pros: - Well-balanced, enthusiast-grade feature set.

- Despite the fact that this is a VA panel (as opposed to IPS), I have another IPS panel display right above mine, and there is no color difference between the VA panel in this display and the IPS panel above it. Because this display is curved, viewing angle differences are negated as well. It's just a beautiful panel. I have zero dead pixels on mine, and no bright areas to speak of.

- Thunderbolt connectivity for current (as of this writing) generation MacBook Pro meaning 100Hz refresh rate capabilities.

- DisplayPort 1.2 connectivity for 100Hz refresh rate from Windows machines with DisplayPort outputs on their graphics cards.

Cons: - Lacks NVIDIA G-SYNC (has Freesync, but realistically speaking, fewer people use AMD than NVIDIA graphics cards. There is supposedly a workaround for this, however I haven't tried it myself: https://forums.evga.com/You-can-trick-NVIDIA-GPU39s-to-use-freesync-and-displays-that-use-DP-v12-to-use-gsync-m2726410.aspx

- VA panel not as nice (on paper) as IPS panels in other monitors.

- Though 100Hz refresh rate is nice, there do exist monitors with better refresh rates (e.g. 144Hz, 240Hz).

Overall Review: - I would absolutely recommend this display to others, especially Mac users.
- I would purchase this display again.
- If I could change one thing it would be to bump the refresh rate to 144Hz and add GSYNC support, but both of these requests would put it into a much higher price range.
