Rated 5 out of 5 by from Unbelievable. Made my decision almost entirely based on the brand loyalty. Bought this CJ791 from nationwide retailer. It came in the CJ791 box. Manufacturer's label reads CJ791. Except it is CF791, based on both ports and what says inside the "menu=>information". Manufacturer's label shows no signs of manipulation. Had a great time returning it in. And you complain about a dead pixel. Quality, huh?

Rated 5 out of 5 by from A great monitor there is so much i enjoy about this monitor. the only downfall is the lack of programs that use it's resolution to the fullest extent. the crisp, clean lines and incredible refresh speed make up for the other thing. a must-have with any computer!

Rated 5 out of 5 by from So much better than dual Monitors After using dual monitors for the past 10+ years I made the change to the CJ791...absolutely no regrets. Running a MacBook Pro and connected via thunderbolt. Awesome resolution, definitely increases productivity, more screen space and no bezel in the middle.

Rated 5 out of 5 by from Excellent Quality. Docking station not working. The screen has excellent quality, you wont be disappointed. However i'm having issues with the docking station. With works with my Dell G5, after installing all drivers. Still not working with my HP X360.

Rated 5 out of 5 by from Monitor tilts due to slack in joint with arm First, I really enjoy this monitor. I can't see myself ever going back to a non-curved monitor. That said, my problem is that the monitor tilts to the right by 1/2" to 3/4". I placed a paperclip in the joint where the arm attaches to the back. It's now level. [I had returned one other with the same issue, so the issue must not be a one off. Btw, my desktop is level, I checked].

Rated 5 out of 5 by from Amazing monitor i love it. i have 2 4k dells at work, and this one i'm using at home. games/work. wide angle view - like in the cinemas. and for work, this setup is working better than just 2 monitors.

Rated 5 out of 5 by from Not for Mac users This is what I consider the "middle ground" for those wanting a sub-4K resolution but decent refresh and response rate for gaming. Unfortunately, the resolution just doesn't quite meet my expectations and this becomes immediately apparent when dragging content from the retina (MacBook Pro) display over to the CJ791; the text is pixilated. My experience with the monitor ended up straining my eyes.

Rated 5 out of 5 by from Very bad quality control Just as many other reviewed. This monitor has very poor workmanship. The monitor came with panel detached from the bezel on the top. The LED light shines through the gap directly. There are also a few dead pixels here and there. I like the features it provides, especially the thunderbolt 3 interface. However, it failed in a very important aspect, the quality. Will have to return it. Buyer beware!

Rated 5 out of 5 by from Broken bezel, lacking support this is my third time to try to submit a review. for whatever reason, samsung won't post my review. i purchased directly from samsung. after a few months, a quarter inch piece of plastic broke off the front of the bezel on the lower right corner. samsung says they don't cover cosmetic issues which is disappointing as it would be a cheap fix and the monitor was so expensive. the monitor seems to work fine otherwise.

Rated 5 out of 5 by from Love Wide Monitors, But Not This One it was lovely for samsung to ask for product experience feedback on the same day i spent 45 minutes on hold with the samsung warranty dept. i've experienced the following issues: 1) the monitor occasionally will emit loud, sickening electrical popping sounds akin to electricity arcing between electrodes. 2) the usb-c connection sporadically doesn?t work. the screen drops out and goes black 3) the monitor is wobbly. it shakes with the smallest nudge. i bought this monitor based on brand loyalty. i recommended it to 3 friends. one friend purchased it as well. regret. the monitor was sent shipped back for repair. let's see is samsung can make this right.

Rated 5 out of 5 by from Thunderbolt port stopped working after 2 weeks great monitor (size, look, etc.), but for this price it should be 100% reliable... and it was not. after two weeks of use the thunderbolt port failed to display picture and audio. now i have to deal with a repair process that is not user friendly.

Rated 5 out of 5 by from AWESOME VIRTUAL SETUP perfect monitor, relatively small footprint. features hdmi, displayport, usbs, usb-c so you can run just about any new system currently available. energy saving features and the picture-n-picture and picture-by-picture are phenomal. charges my mac and beats headphones, the extra ports making adding peripherals a breeze. looking to get one more since its vesa compatible and add it to a two monitor mount.

Rated 5 out of 5 by from great monitor i replaced 2 27-inch monitors with this one and am very glad that i did. it helped to declutter my smallish desk and still enables me to have multiple windows open at once, everything from photoshop to excel. i use this monitor to work from home right now during the pandemic and to post-process photos in lightroom on weekends. the monitor is very sharp, text is clear and images are rendered beautifully. i recommend this monitor to anyone needing a large but compact screen. the monitor is also very attractive; sleek and curved without a lot of messy cords.

Rated 5 out of 5 by from No docking station required I have had this monitor for 2 weeks now and it is amazing. First, it is like having two monitors in one but it takes up very little desktop space. The curved screen is ideal for this set up, a similar effect to having two monitors with each one angled toward the viewer. Second, the picture is amazing - I have never had a high-quality picture for a computer monitor since I use it mostly for work but the 4k definitely is easier on the eyes. My kids have even watched some movies on it and love it! Third, and probably the most amazing feature is the Thunderbolt connection. This means no docking station is required. My keyboard and mouse dongle and USB hub is plugged into the back of the monitor. Just one cable connected to my laptop and the monitor and it functions without a dock. It charges the laptop too. This makes it such a clean setup. I love this monitor and now thinking about getting one for my wife's office! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Good But No Auto Brightness for Mac Maybe I'm too spoiled as a Mac user. There's no built-in camera, okay no problem. But no auto brightness either. Not even keyboard brightness control. This means having to reach back to the tiny joystick and navigating several menus every day. And I'm running two of these side-by-side with a 2018 Mac mini, so that's double the physical fiddling every morning and night, once on the left, then again on the right. As for performance, so far so good, but there's a lag when booting up, even when using Apple's expensive 0.8M active Thunderbolt 3 cable. No built-in microphone, either. Otherwise it's pretty good as an adapted PC display.

Rated 5 out of 5 by from Cant change sources between TB3 Ports I have had this monitor for nearly two weeks. Overall I love it! The picture is good, nice contrast and great response even for gaming. The size, resolution and aspect ratio combine wonderfully allowing your productivity to increase over similar 16:9 screens. There are two major negatives that I can't get over and a couple of other small glitches as well. 1.) You switch sources between the TB3 inputs on the monitor. This is my biggest annoyance. I have a macbook pro with tb3 and a razer laptop with tb3 and there is no easy way of switching between the input sources. I have to power cycle the monitor and turn off the device that I don't want to use. You also cannot do PIP between the two TB3 ports which well...thats annoying. 2.) Samsung made the poor decision to not have a dedicated power button. It takes 3 button presses to turn off the screen. Can't understand the thought process here it's really frustrating especially when I have to constantly power cycle the monitor due to the first problem I have with this monitor. One minor issue - depending on the frequency you do it - it takes a good 15-20 seconds to switch inputs Lastly the built in USB hub sometimes doesn't power on the devices plugged in (i only have a keyboard/mouse attached). When this happens you may have to unplug and plug back in your peripherals or turn off the monitor, unplug everything, turn the monitor back on and then plug everything back in. All of these problems were identical across two different monitors, my first was exchanged due to a faulty OSD joystick controller.

Rated 5 out of 5 by from Samsung Monitor with thunderbolt ports for the win An ultra wide monitor with thunderbolt ports from Samsung?? What more can you ask for! I was surprised with how huge the box was when this flagship monitor came in. I felt like I ordered a new television. The ultrawide 34" screen makes you feel immersed as you watch movies or play games 21:9. I also love the sound quality this monitor makes. It almost felt like a surround sound system and I was amazed as how great the stock speakers were. Some specs of the CJ791 is that it has a refresh rate of 100hz, 4ms response time, 3440x1440 screen resolution, and a contrast ratio of 3000:1. Although it isn't an IPS monitor, the QLED technology covers more than 125% of the sRGB color space making it a great monitor for video editing as well. It's a productivity monster when I used Adobe Premeire for video editing. I could fit the whole time onscreen and then some! The CJ791 also comes with AMD free sync and a game mode optimizing responsiveness and screen lag. The thunderbolt connections take the win for this monitor giving it the crown for one of the first monitors from Samsung with this connectivity. It can transmit video and data at speeds of up to 40Gbps ? 8 times faster than USB 3.0 ? and simultaneously charges devices (up to 85W), all over a single cable. Thanks to the Insiders for letting me test out another great product from Samsung! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from The Thunderbolt 3 widescreen monitor You need I was very interested in this monitor, because I have a Razer Blade 15" 2017. For those not familiar, that is a gaming laptop with a Thunderbolt 3 port. As soon as I turned it on I just had to click ok for a pop up for the Thunderbolt 3 and the monitor showed up right away. Essentially I can have three screens by cutting the Samsung monitor in half and keeping my laptop on. This is a productivity monster. The QLed was another component I was interested in and boy does it have a bright crisp color on the screen. I do not own a MacBook with a thunderbolt 3 port, but I can say with certain that it works without a hitch and is a must buy for those on the market for a widescreen monitor with thunderbolt 3 windows PC.

Rated 5 out of 5 by from A Beautiful Monitor Beautiful. This monitor is absolutely beautiful. From the moment you unpack it till you finish using it for the day, this is just a gorgeous piece of equipment. Positives: - Amazing to look at? even when off - No eye strain, even after a 10 hours of constant use - Great connection options - Fast refresh times - Excellent resolution - Curved Negatives: - Back cover for cord management is flimsy - Expensive This monitor replaced two IPS 19?? monitors. When using those, I had noticed that I could not sit in front of them for a long time; but with this Samsung monitor, I can spend an inordinate amount of time without any eye strain or feeling uncomfortable. While a curved TV seems like a gimmick, using a curved monitor is absolutely amazing. You sit close enough in front of the monitor that having a curved screen actually seems to ?envelop? your view. The colors are comparable to the older IPS monitors, but the single wide screen monitor really makes everything immersive as there is no ?break? in content. The biggest negative that I could find is the price. This is an expensive product, no way around it. The other minor quibble is that in order to ?hide? the power and connection cord in the back of the monitor, the back plastic plate is really flimsy and can easily fall out as there isn?t a locking / snapping mechanism. Fortunately, once set, this becomes a moot point. I recommend this for anyone looking for a top of the line monitor.

Rated 5 out of 5 by from A Worthy TB3 Monitor for Apple Users I completely revamped my set up away from a 2017 MacBook Pro 13" to a 2018 Mac Mini. Although I had a Dell 4k monitor, a widescreen monitor was on my short wishlist for the new set up. Monitor is gorgeous aesthetically. Display quality is top notch and having a single cable connection via TB3 is a boon. Daisy chaining several TB3 devices was a must - Lacie 2Big RAID, BlackMagic external ECU - and this monitor works perfectly. Great for Final Cut Pro. Great for working with two documents, such as an Excel worksheet and a Powerpoint PPT alongside. Highly recommend this monitor!

Rated 5 out of 5 by from Good Monitor but Not a great for Mac users I was looking for a less costly version to the goto Apple compatible displays and don't really need 5K, so thought I would give this monitor a try. I am pleased with the picture quality & picture performance, but unfortunately that is where it ends. The good: Picture Quality for a non-5K display is good Curved screen is much better than I had anticipated The USB hub built into the display gives me options to plug in my other Apple Devices The not so good: No Volume Control from MacOS using Thunderbolt (just crazy) Doesn't provide ability to control any display settings from MacOS like the other manufacturer (such as brightness and volume) Joystick control is not in a very convenient to reach place and you have to use it to do anything with this monitor (another dig on the fact you can't adjust anything via MacOS) After using this monitor for a few weeks, I have ordered the 5K display from Apple as I just really miss: Volume Control Brightness Control Automatic Dimming Built-In Camera If you use your own speakers, don't need a camera, really don't want to spend the money on a 5K display & don't think you will need to adjust brightness or have MacOS automatically dim, then this could be a good monitor for you.

Rated 5 out of 5 by from Display is great, USB ports not working on Win 7 I did buy this monitor mainly because of it's thunderbolt support and ability to connect pheripherals. When it comes to the display itself, it is awesome, it is a huge productivity boost. I am using Dell Precision 7520 workstation, having all drivers up to date, but windows cannot find the drivers for the usb controller.However, everything works with Macbook Pro computer, so the problem is not in the hardware. I managed to have chat over an hour online with Samsung support. It was surely very polite discussion but useless, since i got the same questions over and over again, like which cable am I using. I requested to have a contact with technical support which was simply ignored. Now I tried to send an email from the website and it is impossible! After filling the form the response is "no session". Let's see if the review goes through. If I'm not getting the solution to the problem, I'll return the product.
