Update: Update to clarify some differences between CJG50 and CJG52 models. News piece below initially published 23rd June 2018.


The Samsung C27HG70 and C32HG70 are interesting monitors. The combination of 2560 x 1440 (WQHD) resolution and VA panel is enticing to some, and quite a rarity in the case of the 27” model. Designed with gaming in mind, additional features of interest include support for a 144Hz refresh rate and ‘HDR’. The main criticisms around the smaller model focus around uniformity issues which affect many units and for the larger model the fact that the backlight isn’t ‘flicker-free’ as advertised. The Samsung C27JG52 and C32JG52 have the potentially to address these issues, making use of a different backlight arrangement. As seems to be the theme for the manufacturers ‘J’ series (2018) models, they seem to be pared back versions of last year’s ‘H’ series offerings. Notably, the Quantum Dot backlight and HDR support has been dropped whilst other core features remain intact. These models differ aesthetically from the ‘HG’ variants as they have a dark silver-coloured bottom bezel but more notably because they feature a dual-stage bezel with a thin panel border and very slim hard outer component. Rather than a thicker hard outer component that covers the panel border. The JOG button (joystick) has been dropped in favour of simple pressable buttons on the underside of the bottom bezel for control of the OSD (On Screen Display).

The front

The monitors use 27” (C27) and 31.5” (C32) VA panels, offering a 1800R curve for added depth and immersion. A 2560 x 1440 (WQHD) resolution is supported alongside a 144Hz refresh rate, although no variable refresh rate technology (such as FreeSync) is supported. A 3000:1 static contrast is specified alongside 178°/178° viewing angles, whilst a light matte anti-glare screen surface is employed to preserve image clarity and vibrancy better than some matte screens. 8-bit colour is supported on both models (likely ‘true 8-bit’ without dithering). A flicker-free WLED backlight is used which offers 300 cd/m² typical maximum brightness and ~sRGB colour gamut coverage and possibly a bit of extension beyond. The extension beyond this is expected to be somewhat lower than for the Quantum Dot solutions used previously, but hopefully both models are actually flicker-free as advertised this time. Samsung’s popular ‘Game Style UI’ OSD returns alongside features such as the ‘Low Input Lag’ mode which minimises signal delay and the ‘Black Equalizer’ feature that enhances visibility in dark scenes at the expense of accurate shade reproduction. A 4ms grey to grey response time is specified – so there is no ‘1ms MPRT’ response time of strobe backlight mode this time. We don’t see this as a bad thing, given how poor the implementation was anyway. You’ll actually be able to control the strength of pixel overdrive this time without this acting as a switch for the strobe backlight mode.

The rear of the monitor again reflects simplification of the design and feature-set. The (admittedly rather deep) monitor arm has been replaced by a simple tilt-only stand. 75x75mm VESA holes are included for alternative and more flexible mounting. The ports are located to the right of this with a removable cover included, plus a ‘cable tidy’ hole in the cover to feed cables through. The ports include; 2 HDMI 1.4 ports, DP 1.2, a 3.5mm headphone jack and DC power input (external power brick). HDMI is included for connection to devices such as games consoles but given the lack of HDR support Samsung decided there was little reason to go for HDMI 2.0 this time around. No USB ports are included this time, either.

The rear

Further information on the C27 and C32 can be found on the company’s website. Additional variants are also listed (C27JG50 and C32JG50) which have a slightly different OSD and feature set. They lack the ‘Game Style UI’ OSD system and related features such as ‘Low Input Lag’ mode, monitor-side refresh rate selection (‘Refresh Rate Optimizor’) and gamer-centric settings like ‘Black Equalizer’ (enhances visibility in dark scenes at expense of accuracy) and some gaming presets. The product itself appears to be similar, with the ‘50’ models being marketed for office and general-purpose use vs. gaming. The C27JG56 and C32JG56 are also available, which come bundled with slightly different accessories to the ’52’ variants but are otherwise identical. These monitors are now available globally.
