Review on 💻 Samsung CJ791 Thunderbolt Curved Monitor 34" 3440x1440p 100Hz with Wide Screen and USB Hub, LC34J791WTNXZA by Jared Ali

*Update 3*My replacement screen now has a few dead pixels as well as a few pixels that won't peel off in various ways. Not too happy with overall quality control. Potential on this screen but quality control issues prevent recommendation. Finally, when you have two TB3 devices connected, you can switch between them by completely turning off the power to one while leaving the other powered on. This will switch the input and you can turn the other device back on. Not the most convenient process, but I find it easier than unplugging cables.*** UPDATE 2 ***Some very important points when considering this monitor: #1 Bad point: YOU CANNOT SWITCH SOURCES BETWEEN 2 TB3 SWITCHING INPUTS. If 2TB3. You must turn off the MONITOR as well as both devices completely, then turn on the device you want to use and the monitor will accept the correct TB3 input. Again, you cannot switch input sources between the two TB3 inputs. It stinks. #2 Bad element: You can't just press the power button to turn it off. You have to go through the OSD to turn off the monitor, which takes 3 clicks for a function that should be 1 click. Really annoying and really terrible IMHO. #3 Bad Element: The monitor consistently won't turn on your peripherals. In this case you may need to turn the monitor off and on again by disconnecting the devices from this screen. It's really annoying. I still stand by the picture quality, but this monitor has so many other downsides that it might be better to wait until the next gen or another brand has something similar (if you need 2 TB3 inputs)**** * ***UPDATE*** After using the monitor for only 4 days, the joystick that controls the screen display stopped working when pushed in a certain direction. I call Amazon, I hope they exchange it immediately. After becoming accustomed to mostly laptop screens over the past decade, I wanted an ultra wide screen and found it difficult to choose a screen. I was between this monitor and the new LG. 34gk950f, which has been retired because it is not widely ordered, and the old Alienware AW3418DW. I've seen Alienware in person a few times, and while the gameplay is awesome on screen, the colors weren't very bright and it felt a bit dull. As I will be using it for work, media and gaming I've seen Samsung and the contrast ratio is slightly better compared to Alienware. So my choice was made and I hoped for the best for the game. Now here are my thoughts after a short day with him; I will update this review in the future.********NOTE********In Windows at 100% zoom, text is clean and crisp, looks great on websites, documents, etc. e. In Mojave 10.14.3 scaling is not perfect. The images still look good, but the text is a bit jagged. You can play around with the settings and make them a little better, but oddly they look better on Windows 10. I don't like the VESA mount for this monitor at all. Sure, it's actually pretty easy to remove the pre-assembled stand and install the bracket, just 2 Phillips screws, but the design adds about 2 inches of depth to the monitor, if depth is an area I'm already missing. could be easily solved by mounting the flat piece on the back of the monitor or positioning the vesa attachment point on the monitor itself perpendicular to the back of the monitor and attaching the adapter plate in the same way. They plan to adjust this so that the screen is 2 inches lower than it should be. The build quality of the frame and the stand itself is fantastic. It's all plastic but doesn't smell cheap, it definitely feels sturdy. The 'joystick' on the back of the display easily controls the OSD menu and when pressed turns the screen on and off. If you want to use the stand, it does have a detachable cable management panel, but it doesn't look like it can hold 3-4 cables at most. A final note on cables; You are good! Samsung stepped in and delivered very high quality HDMI, and the power cord here ensures you're factoring in a HUGE power supply. They also included a 2m Thunderbolt 3 cable, which is also of high quality. screen quality. So I don't have any professional tools, but there are factory-saved calibration results that you can view on the OSD and there is an option to fine-tune. Unlike my 2018 Macbook Pro, the colors have a slight red cast, but they are very close, but the blacks on this Samsung VA panel are much better than the MacBook. It's not perfect, the blue/green colors aren't that well defined here, but overall it's again a fantastic picture on this panel and the 100Hz refresh rate makes web browsing and video playback very smooth. Choosing a 21:9 34+ monitor is so difficult because no monitor seems to have it all, KVM, 1440p+, 120+ refresh rate, speakers (I know they suck but I want them), gsync/freesync, a Thunderbolt 3 connection Samsung really doesn't have everything, but TWO TB3 ports (1.85W 1.15W), KVM functionality and a decent 100Hz refresh rate drew me to the screen. I use KVM a bit because it's not real KVM BUT if you use two computers with TB3 it works fine and you can just choose which computer should have OSD control. Super easy and awesome feature for both me and me. The display is connected to my 2018 Mac and a 2019 Razer Blade 15 and I can switch between KB/Mouse functionality, split screen or PIP. Sound quality - there are not many words here. It gets loud enough to fill a small room with no real bass or clean highs, but it's not the worst I've heard and it's far better than 99.99999% of laptop speakers. It's acceptable for what it is, no more, no less. games. Considering 100Hz and based on my 2019 15-inch 144Hz Razer Blade screen, I thought the step down would be very noticeable. I can definitely say it's not that smooth, but still very smooth gameplay. No Free/GSync, that could be an issue, but as a casual gamer I did notice the difference, but it was minor and I'm glad to sacrifice that. Increase the resolution and get a wider FOV. (in most games). Aside from the refresh rate, the input lag was pretty good and shouldn't concern anyone but the best pro gamers. Which brings me to the next topic, which isn't so much about the quality of the monitor. but an idea of what you might need to run it. hp So my Razer Blade 15's gaming rig' has a 2060RTX, i7 8750h hexa-core processor, 16GB DDR4 and 512GB Samsung NVME. Two games I've been playing lately: Path of Exiles and Apex Legends, here is a very brief FPS breakdown: Apex Legends @ 1080p with R TX 2060----------@3440x1440p----Average 105--------------- - ----- -- -- average 80 In Apex settings mostly maxed out (no AA), still very playable at this resolution with 2060 RTX and not dropping below 70 fps (2060 on mobile, not even forgetting !) Path of Exiles @ 1080p with RTX 2060 -------------------- @ 3440 x 1440p ---------------- ---- 120 fps average ----- ---------------------------90 fps average ------- Windows No idea why but PoE consumes a lot more frames going to higher resolutions but still averaging 90 fps at native resolution with max settings In terms of performance and modern gaming it would e I say that 1070/2060 would probably be the minimum you want if you want to play at native resolution. Resolution and frame rates in the 60-100 range in MOST modern AAA games. Aside from the VESA mounting bracket, I really like this monitor. It's bright, rich, and high-contrast, playing games smoothly with little to no motion blur. The speakers are decent and with 2 TB3 ports the KVM functionality for $800 and under is great value!
