Samsung announced the new CJ79 monitor at IFA 2018 yesterday. The CJ79 is a 34-inch ultra-wide QLED monitor with Thunderbolt 3 connectivity. The display features a VA panel that offers a 3000:1 contrast ratio and comes with support for AMD FreeSync.

At IFA 2018 yesterday, Samsung took wraps off its new C34J791 monitor. The CJ79 is a 34-inch curved ultra-wide monitor with a curvature of 1500R. The monitor can be hooked up to PCs and Macs and comes with Thunderbolt 3 connectivity, which allows connecting peripherals at up to 40 Gbps while simultaneously charging them.

The CJ79 is in the same ultra-wide category as the CJ89 that was launched last month. The CJ89 is an ultra-wide 1800R curved panel that is available in 43-inch and 49-inch variants with a resolution of 3840 x 1200 and 3840 x 1080 respectively. While the CJ89 offers a larger screen estate and more curvature than the CJ79, it does not offer Thunderbolt 3 connectivity.

The 34-inch curved display in the CJ79 is a VA panel with a high native contrast ratio of 3000:1 and a brightness of 300 cd, which should be more than enough for indoor environments. The high native contrast ratio should result in inky blacks and more punchy colors compared to a conventional IPS panel while still offering a wide 178 degree viewing angle. The ultra-wide resolution of 3440 x 1440 yields an aspect ratio of 21:9. Samsung says the monitor has a Grey-to-Grey (GtG) response time of 4ms but it will be interesting to see what the Black-to-White (BtW) response time is. 

Apart from the two Thunderbolt 3 ports, the CJ79 also comes with 1 HDMI port, 1 DisplayPort, and 2 USB 3.0 ports. The adjustable stand supports tilt and height adjustment and the monitor is also VESA complaint for wall mounting. There is no mention of the display being 10-bit so in all likelihood, the CJ79 does not support HDR standards such as HDR10 or Dolby Vision. However, the CJ79 supports AMD FreeSync for tear and stutter-free videos and gaming.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
