Review: Samsung’s 34-inch ultra wide monitor with Thunderbolt 3 is a tempting choice for MacBook users

While most ultra wide monitors on the market with Thunderbolt 3 go for well over a thousand dollars, Samsung offers an interesting option with a 34-inch curved display, Thunderbolt 3, and a more affordable price. The CJ791 doesn’t bring a 4K resolution to the table, but it does come in at $800 with a compelling overall package. Read on for our full review of this ultra wide Thunderbolt 3 monitor that works well with the MacBook Pro and other MacBooks.

While Apple’s upcoming Mac Pro and Pro Monitor are still mostly a mystery, there aren’t a lot of choices out there for Thunderbolt 3 monitors for MacBook Pro and MacBook users.

There’s the Apple endorsed LG UltraFine 27-inch 5K display sold at Apple Stores, but at $1,300 retail price, it’s expensive for a product from 2016. LG also makes a 4K 32-inch monitor which retails above $1,000 (reviewed), and there’s the LG 34-inch 5K2K monitor which normally goes for around $1,400-$1,500 (reviewed). With all these choices over $1,000, I was excited to test out Samsung’s CJ791 Thunderbolt 3 Ultra Wide 34-inch Curved Monitor that sells for $800 (MSRP $900).

Materials & Build

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 monitor sits on a circular base that offers nice stability, and it’s easy to raise, lower, and adjust the tilt of the display. The back of the monitor features a glossy white finish and there’s a thoughtful cable organizer built into the stand’s arm.

Exposed on the back of the monitor are two traditional USB ports, 3.5mm headphone jack, and a 5-way power/toggle button. Behind a removable cover panel are the power input, two Thunderbolt 3 ports, HDMI, DisplayPort, and a service port.
