Pros
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.
Pro Excellent for general use
The Samsung CHG90 offers much higher versatility than the overwhelming majority of the competitors on the market because of its picture quality, HDR support, gaming performance, and the amount of on-screen real estate.
Pro Supports HDR media
Combining its color gamut, HDR peak brightness, and native contrast ratio with full HDR10 support, the Samsung CHG90 outperforms the nearly all of its competitors when it comes to the HDR media playback.
When working with HDR media, the Samsung CHG90 can display almost 90% of pure HDR colors of the DCI P3 color space because of the monitor’s wide color gamut. Such DCI P3 coverage is an uncommon feature for a general purpose monitor. DCI P3 is the color space used in HDR media production.
Moreover, the monitor has enough luster to highlight vivid objects in HDR mode where its brightness peaks at around 600 nits.
Additionally, the Samsung CHG90 is among a handful of monitors that support HDR10.
Pro Handles motion quite well
The Samsung CHG90 displays good-looking motion with only some minor traces of motion blur following fast-moving objects on the screen as the monitor’s pixels need only around 10.8 ms to change their color. Such rapid pixel transition is achieved because of the monitor’s full pixel response time of 10.8 ms.
Additionally, the monitor doesn’t suffer from any noticeable ghosting.
Furthermore, the motion looks smooth because of the monitor's 144 Hz native refresh rate, which ensures that the Samsung CHG90 displays a new frame every seven milliseconds.
Pro Has a curved screen
The Samsung CHG90 offers a highly immersive experience as you can literally feel its 1800R curve surrounding you.
Pro Fights glare
The Samsung CHG90 works very well in bright rooms with lots of windows as its light matte coating and high peak brightness does an excellent job of fighting glare and heavy reflections.
Pro Highly responsive
The Samsung CHG90 is among the most responsive monitors on the market as its input lag measures at an amazingly low value of 4.6 ms.
A monitor’s input lag is significant in gaming as it shows how much time a monitor needs to process a frame generated by a computer’s graphics card.
Pro Supports FreeSync 2
FreeSync eliminates tearing and reduces stutter because it allows the Samsung CHG90 to synchronize its refresh rate to the framerate of your AMD graphics card.
FreeSync 2 is an advanced AMD technology which combines adaptive synchronization with HDR. AMD claims that only the best HDR monitors would be compatible with FreeSync 2.
Pro Suitable for web designers and photographers
Because of its full sRGB coverage, the Samsung CHG90 is an excellent tool for media artists, such as web designers and photographers that work in the sRGB color space.
Additionally, Samsung CHG90 is suitable for those who make videos for web applications, like YouTube and Twitch, as those also use the sRGB as a default color space.
Pro Massive amount of display real-estate
The Samsung CHG90 is a fantastic tool for productivity as its 49-inch 3840x1080 display offers enough real-estate to place three Google Docs side by side comfortably. The monitor will also come in handy for those working with massive Excel sheets because of its large on-screen area.
Furthermore, the monitor’s picture-by-picture mode allows the Samsung CHG90 to display pictures from different sources simultaneously. Such a feature will make your life much easier if you use a laptop alongside your desktop computer.
Additionally, you can manage and organize your workspace using Samsung’s Easy Setting Box.
Pro Good for gaming
The Samsung CHG90 offers better gaming performance than the overwhelming majority of 40”+ competitors, as this 144 Hz monitor offers highly responsive gameplay with reasonably well-handled motion.
Additionally, due to the monitor's aspect ratio of 32:9 you’ll have a wide field of view in games like CS: GO, DotA 2, League of Legends, and Star Wars Battlefront.
Pro Good picture quality
The monitor’s native contrast ratio, peak brightness, gamma, color accuracy, and color uniformity are superior to what the overwhelming majority of competitors on the market offer.
It can display amazingly beautiful images, with a wide range of vivid and accurate colors, rich and intense blacks, and some eye-catching intermediate tones that look genuinely accurate. Colors pop,and look crisp because of the monitor’s peak brightness of 331 nits, which, combined with the CHG90’s high color uniformity, makes the colors appear consistent across the entire panel. Dark scenes look deep because of the monitor’s native contrast ratio of 3756:1 which makes its blacks appear truly dark. Mid-tones look life-like as the monitor’s gamma is less than one percent off from the ideal value.
Additionally, the Samsung CHG90 can display a higher variety of colors than the majority of its competitors because it uses a true 10-bit panel that allows it to reproduce more than a billion colors.
Furthermore, the monitor’s color inaccuracies are so insignificant that the human eye can't see those since the panel’s average color error dE is only 1.13.
Pro Good for HDR gaming
With the Samsung CHG90, you’ll be able to experience true HDR effects in games that support it like ARK: Survival Evolved and Battlefield 1.
Cons
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.
Con Some games might not support 32:9
Games that support only the aspect ratios of 16:9 or 21:9 will have vertical black bars on the sides of the Samsung CHG90, as the monitor’s native aspect ratio is 32:9.
However, the majority of new titles do support a 32:9 aspect ratio.
Con Flickering can cause eye strain
The Samsung CHG90 flickers because it uses a PWM signal to dim its backlight. Monitor flickering can cause severe eye fatigue after extensive use.
Con Not suitable for consoles
The current generation consoles don’t support an aspect ratio of 32:9 and will leave massive black bars on the sides of the screen if connected to the Samsung CHG90.
