![]() The area bounded by the triangle represents all the colors that can be displayed by mixing the three primary colors, so any points outside of the triangle represent an expansion of the normal RGB color gamut. A Wide Color GamutĬolor accuracy for the CHG70 proved to be very good in our testing.Īs illustrated on the chromaticity chart below, with the CHG70 tested in sRGB mode, the red, yellow, green, aqua, and purple color measurements (represented by the colored dots), though fairly evenly spaced, are all well outside the triangle depicting the normal bounds of the CIE RGB color space (represented by the boxes). Samsung covers the CHG70 with a three-year warranty for both parts and labor. The CHG70's input port selection includes two HDMI 2.0 ports, a DisplayPort 1.4 connector, one upstream and two downstream USB 3.0 ports, and separate audio-in and microphone jacks. It is also possible to customize numerous settings within a mode. From these buttons, you can control brightness, contrast, and sharpness, as well as change the display mode (sRGB, Cinema, Custom, and High Brightness, in additional to FPS, AOS, RPG, and RTS gaming modes). The on/off button, which doubles as a miniature directional joystick, is in back and situated well to the right of the other three, which are downward-facing and let you access the onscreen display (OSD) settings. The physical controls on the monitor body comprise four tiny buttons located on the bottom right edge. I measured its contrast ratio at 2432:1, short of its 3000:1 rated contrast ratio but still a respectable figure. I measured 372.1 nits in sRGB mode in our quantitative testing using a Klein K10-A (Opens in a new window) colorimeter and SpectraCal CalMAN 5 (Opens in a new window) software. The CHG70 is rated at a native luminance of 350 nits, and it tested slightly better than that. The high curvature makes for a more immersive gaming experience than you would get with a flat panel. Among monitors we've tested, only the Samsung 34-Inch CF791 Curved Widescreen Monitor boasts a tighter (1500R) curvature rating. This is the same curvature as the Samsung CHG90 and among the tightest curvatures we've seen. The panel is highly curved, with an 1800R curvature rating, which means that enough CHG70 27-inch monitors placed side by side to form a full circle would yield one with a radius of just 1,800mm, or 1.8 meters. ![]() (See our guide to the best graphics cards for 4K gaming.) Another recently reviewed Editors' Choice, the deluxe Acer Predator X27, with 4K resolution, has a much greater pixel density (163ppi), but it sells at a much higher price than the CHG70, and it requires a more powerful graphics card to run at reasonable frame rates at its native resolution. That should provide a sharper image than the Samsung CHG90 and its pixel density of 81ppi, or the Asus ROG Strix XG32VQ (91ppi), when viewed at the same distance from the screen. ( See this primer for more on QLED.) It has a standard widescreen aspect ratio of 16:9.Īt that screen size and resolution, its pixel density is 109 pixels per inch (ppi). The 27-inch panel is a vertical alignment (VA) display that uses Samsung's version of Quantum Dot (QLED) technology. The native resolution of the CHG70 is WQHD, or 2,560 by 1,440 pixels. (Opens in a new window) Read Our Asus ROG Strix XG32VQ Review For the sake of clarity, all references I make to the CHG70 in this review other than in the previous sentence are to the 27-inch model. It's enough to make it our latest Editors' Choice gaming monitor.įirst, a note: Samsung sells a 32-inch version of this monitor, also under the model name CHG70, which PC Labs hasn't had a chance to test. It features a wide color gamut and a super-high native refresh rate of 144Hz, and it supports AMD's latest iteration of its adaptive sync technology, FreeSync 2, for Radeon-card loyalists. It does a nice job displaying both games and video in standard definition and HDR (the latter with the expected vivid color and excellent contrast). The $499.99 CHG70 does stand out, however, for a winning mixture of features and performance at its price. Its resolution and aspect ratio are commonplace among 27-inch gaming monitors, and its appearance-apart from the novel design of its base-is unassuming.
