Samsung Announces First QLED Curved Monitor With Thunderbolt 3

by

Last month, LG announced a new set of Thunderbolt 3 monitors to be officially unveiled at CES 2018. Not to be outdone at the January event, Samsung today unveiled the first curved display with Thunderbolt 3 connectivity.

The 34-inch CJ791 monitor features a 3,440 × 1,440 UltraWide QHD resolution with a 21:9 aspect ratio, while the single Thunderbolt 3 cable delivers a connectivity speed of up to 40 Gigabits per second to a range of docks, displays, and peripheral devices, including Macs and external GPUs. The Thunderbolt 3 interface also allows the CJ791 to supply up to 85 watts (W) of charging power to USB type-C compatible MacBooks.

The specs can't quite match LG's upcoming 34-inch UltraWide 34WK95U, which has a 5K resolution of 5120 x 2160 pixels, but apart from multi-peripheral connectivity, Samsung is eager to promote the CJ791's QLED display as ideal for gaming and entertainment. With "precise" performance across 125 percent of the sRGB color spectrum, a 4 milliseconds response time, and a sharp 1,500R curvature and ultra-wide 178-degree viewing angle, the CJ791 should still turn some heads at this year's CES. The company is also touting the monitor's built-in Game Mode, with a dynamic gamma setting that allows the CJ791 to adjust the color and contrast of individual scenes as they're displayed.

There's no word yet on the price of the 34-inch CJ791, but hopefully more should be revealed when CES opens its doors on January 9 for four tech-filled days at the Las Vegas Convention Center. Stay tuned to MacRumors for all the highlights.

I will never understand the appeal of curved displays. To me it’s like needing a spirit level and being given a banana.

But fair play to those who like them (curved displays, spirit levels or bananas).

We already have curved LCD displays. QLED is a marketing trick which Samsung tries to implement in the place of OLED.

It’s time to support Rec.2100 12-bit colour gamuts. Enough about resolutions.

Does everyone just want to wait for Apple?
Apple does not produce their own panels..

Curved displays will soon join 3D TVs I suspect.

Curves are bad on a TV. Curves are great on a monitor and on Scarlett Johansson.

For TVs, curved displays make zero sense. They reduce the angles you can comfortably view the display from and how many people can watch at one time. They increase reflections. It’s frankly stupid.

With computer monitors that you sit close to get over a certain size, however, the angle between the middle of the display and the edges changes so dramatically that you see LCD color shift substantially and the image distorts. This is why very wide monitors need a curve. At work I use a Philips 40” 4K monitor which is great for productivity because of the height for reading code and text - but I basically can’t stand having anything at the left and right edges because the angle is so far off of normal. Newer versions of my 40” monitor are curved and I wish I had a subtle curve like that.
