LG 27UD68 ‘4K’ UHD model with FreeSync
The LG 27UD68 (also referred to as the 27UD68-P or 27UD68-W for the black and silver coloured stand, respectively) adds to the ever-expanding range of monitors with VESA Adaptive-Sync. By supporting this standard, the monitor can be used with AMD’s FreeSync variable refresh rate technology to help eliminate stuttering and tearing from transitional frame rate and refresh rate mismatches. This model features much sleeker styling than its predecessor, the 27MU67. The ‘cinema bezel’ design is again used. This comprises a hard plastic outer component as well as a thin panel border – the latter is not clearly visible in the image or indeed when the monitor is off. The total bezel width at the top and sides is 9.1mm and is 20.4mm at the bottom. The stand base appears to be brushed metal, whilst the included stand provides tilt as the only ergonomic flexibility.

The monitor uses a new 27” AH-IPS panel with 60Hz refresh rate and 3840 x 2160 (‘4K’ UHD) resolution. The monitor supports AMD FreeSync with a variable refresh rate range of 40 – 60Hz. Other aspects of the specification which may be of interest include a 1000:1 specified static contrast ratio, 178° horizontal and vertical viewing angles and a very light matte screen surface. 10-bit colour is supported via 8-bit plus 2-bit FRC dithering. A 5ms grey to grey response time is specified whilst a flicker-free WLED backlight is employed, offering 99% sRGB coverage (and likely some extension beyond sRGB in some areas). The specified maximum luminance is 300 cd/m² and ‘Low Blue Light’ settings are also featured. There is also a ‘black stabilizer’ setting which enhances gamma at the low-end to make certain dark areas more visible than they should be – revealing extra detail, much like BenQ’s ‘Black eQualizer’. Perhaps more appealing is the ‘DAS’ mode (‘Dynamic Action Sync’), which is designed to bypass extraneous processing by the monitor and therefore minimise input lag.
The ports of the monitor include; DC input (external power brick), DP 1.2a (with Adaptive-Sync), 2 HDMI 2.0 ports and a 3.5mm headphone jack. Both DP 1.2 and HDMI 2.0 support the native 3840 x 2160 @ 60Hz, but FreeSync requires the use of the DisplayPort input and of course compatible GPU. Another model with the addition of USB Type-C ports but seemingly no FreeSync support is also in the works (the 27UD88 or 27UD88-W). The rear of the monitor is white and looks quite barren, but some will be relieved to hear that 100 x 100mm VESA holes are included for alternative mounting to a compatible stand or mount. You can see this in the image below.

Further information on this model can be found on certain regional websites for the manufacturer, such as their Japanese one (requires translation into English). The monitor is now available for under £450 in the UK and under $500 in the US.
