Ranked in these QuestionsQuestion Ranking
Pros
Pro Blue light filter reduces eyestrain
Samsung has used its own measures to filter out and eliminate the amount of blue light emitted from the screen if needed and requested. Blue light has been proven to decrease sleep quality; this feature is especially helpful when used during the night.
Pro Works well in brightly lit rooms
The C23F390FHU features an anti-glare panel, which significantly reduces or eliminates reflections, loss of clarity due to light, fingerprints and smudges.
Pro Mirrored finish doesn't attract fingerprints
Despite the glossy, mirrored finish of the C23F390FHU's frame, it does not attract fingerprints and smudges keeping the enclosure clean.
Pro Looks great from every angle
An advantage of the VA-panel is the maximum range of the viewing angles. The monitor looks great from every horizontal and vertical viewing angle and color shifting (distortion of colors) doesn't occur.
Pro Curved display increases visual workspace
The C24F390FHU is curved and is angled similar to the curves of the human eye. Points on the screen are spread more evenly across your eyes, which increases your visual workspace at a normal distance and can reduce eyestrain.
Pro Excellent image quality with great color reproduction, suitable for graphical work
The VA panel is produced by Samsung and offers a couple of advantages compared to TN-panels. The image quality is excellent with vibrant colors due to the VA's panel natural higher color reproduction and a good contrast ratio of 3000:1.
Pro Cinema-like picture quality for an affordable price
The fact that a monitor of this price range has a 5M:1 contrast ratio is simply astonishing. This means users get cinema-like picture quality right at their desk.
Pro Good sound quality with no need for external speakers
This monitor's speakers are as good as those found on small TVs. They're located in the back and come with an audio jack for headphone connectivity.
Pro Immersive
The 2560x1080 resolution creates an immersive setup. This applies even for work tasks: multiple documents can be displayed side-by-side with no legibility sacrifice. It's equivalent to having two monitors with 1280x1080 screens.
Pro Advantageous for all uses
This monitor's ultrawide screen has advantages for all uses. When it comes to movie watching or gaming, the screen size contributes to a truly engaging experience. As far as general productivity goes, the ultrawide screen makes it easy to have different applications or documents open side by side.
Pro Great for watching movies
The 21:9 aspect ratio comes in handy when watching movies. This is the default aspect ratio at which almost all of the films are shot. Hence, you can watch your movies without having two black bars at the top and bottom of the screen.
Cons
Con No built-in speakers
There are no small speakers built-in for normal use, the use of additional speakers or headphones is necessary.
Con Lack of DisplayPort or DVI ports limits connectivity
The C24390FHU doesn't have a DisplayPort input, a relatively new connection standard that's widespread among recent graphical cards. The older, digital DVI-port isn't supported either.
Con Refresh rate limited to 60Hz not great for fast-paced action
The maximum refresh rate of this display is 60 Hertz, or 60 frames per second. Some other display offer a much faster refresh rate of 120 or even 144 Hz, which increases overall fluidity and responsiveness of the display, especially in gaming situations.
Con Build quality isn't optimal, feels a bit wobbly
Although Samsung hasn't chosen cheap plastic materials, the monitor does feel a bit wobbly around the neck-area, which may result in accidental sliding.
Con Slower response time makes it less ideal for gaming
The response time for the screen is limited at 4 ms, which is significantly slower than some other monitors. This makes the C24390FHU less ideal for gaming situations that require fast-paced input.
Con Limited connectivity
This monitor has two HMDI ports, which is pretty good. However, it misses other display inputs such as DVI or Display Port, making incompatible with older computers.
Con Lack of support for ultra-widescreen in (old) games
A handful of games do not support 21:9 aspect ratio by default. Some examples are Overwatch, Fallout 3, and Starcraft 2. If this is important for you, it is recommended you test this issue before getting this monitor. But there are solutions: you can either install fixes (only available for some games) or play in windowed mode, using a different aspect ratio.
Con Slow response time
A response time of 5 ms on a gaming monitor is pretty awful. Considering its refresh rate, it is understandable but not acceptable. Note that this response time is from gray-to-gray.
Con 720p and 1080p videos are sandwhiched
This monitor's aspect ratio means that many online videos, such as those from Netflix or YouTube, will have black spaces on the sides, which can be annoying.
