Thunderbolt ™ 3
The CJ79 has two Thunderbolt 3 ports for connecting Mac and PC computers. Thunderbolt 3 ports transfer video and data at speeds up to 40 gigabits per second, eight times faster than a USB 3.0 port, and at the same time charge the devices (up to 85 W), all at the same time. means of one and the same cable.
Curved for your comfort
The curved slab is designed to match the natural curvature of your eyes, ensuring optimal visual comfort, even after long hours in front of the screen. Studies at Harvard University and Seoul National University Hospital have shown that CJ79, unlike flat screens or less curved displays, reduces eyestrain.

Quantum Dot Colors
Quantum Dot technology provides incredible coverage of the sRGB color space, offering not only more colors than conventional screens, but also brighter, crisper and more natural colors, especially on reds and greens. In addition, each monitor is calibrated at the factory to ensure accurate and accurate color reproduction.

AMD FreeSync technology synchronizes the refresh rate of your graphics card and CJ79 to reduce image problems and jerks. The seamless transition between images ensures an optimal gaming experience and perfect video playback.

This screen hits the perfect balance between a gaming monitor and a work station eesential. I've had this product a year now and have only had one issue with it.
The ports are fixed in upside down which seems to be a problem only I am experiencing. The display and hdmi ports are fine and will hold but the power cable falls out super easy and my only solution is to tape it up so it can not fall again. This may just be a personal problem but still be a little mindful I guess :)
A great monitor for a great price
I replace my two monitors with this one and its great. The picture is clear, although I did dial down the brightness as it was too bright. It was great to cut down on the number of cables I had lying around too.
Great Monitor for daily use and gaming
Adjustable tilt and height
More immersive in games due to the wide and curve screen
Monitor looks nice (personal opinion)
Has a buzzing noise but won't be noticeable if you're playing music or games.
I would like it to have more hmdi ports (personal opinion)
The Best Monitor for me.
I got a good deal for this one from the tech expo, I've been eyeing this product for while now and when it got on sale on tech expo, I couldn't miss the opportunity like that.
Pros: The Wide angle with Quantum dot color graphics and the 2 thunderbolt 3 port that it has.
cos: probably the con about this is that the speakers are just average and it takes a while for it to load.(from sleep mode to actually using it)
I would buy another one just to fully complete my ultra wide angle minimalist set up.
Monitor looks and works great. The Quantum Dot display has a great colour-range and good accuracy. I've been using it for two weeks now with a Surface Book 2 and it has worked great after doing a couple of updates. It's great only having to use a USB-C cable for display, USB and charging. Although the curve is stronger than with most curved ultrawides you get used to it very quickly and it makes the screen much easier to view. Only con is the USB hub doesn't seem to accept USB2 devices (only USB3 devices seem to work), although this may be fixed with a driver update in the future.
Worth the investment
Great product. Plug and play for multiple devices and great picture quality. Can not complain at all
Nice wide screen monitor
Works great on my Mac mini M1, and feels to provide more usable screen space than two monitors.
Running one wide monitor is much more practical and less cluttered than two monitors.
Nothing negative noticed to date.
Perfect for what i wanted
Got this as both a gaming monitor, as well as an ultrawide to help me code. Fits all html css and js nicely on the screen at once, whilst not being awkwardly wide when gaming. No complaints here and the 100htz looks super smooth.
My first ultrawide
It’s the first ultrawide monitor I’ve bought and definitely the most premium monitor I’ve ever bought so far. I upgraded from using two mismatched monitors I’d picked up over the years and wanted something that would give me a similar amount of screen space. I’ve used this monitor for about 3 weeks so far.
Good colour and fairly bright screen with contrast contrast.
The design is attractive.
The resolution of 3440x1440.
The 100hz refresh rate makes things feel just that bit smoother than 60hz.
Viewing angles are good.
Fits nicely on my desk and takes up less space that two monitors.
I’ve had issues with quality which is...view more
Love it. Perfect good price.
After replacing my two old monitors, I'm wondering why I did not do this earlier. The 34" Curved Monitor is the best looking monitor I've ever used. I'm very happy with my purchase.
Low power USB port
I connect my macbook pro to this monitor via HDMI. If I plug my iphone into the monitors USB port, it does not charge, but a low power USB fan does charge, so that's a little disappointing.
Otherwise, having a 34" is helpful when working on multiple documents at a time.
