LG 27EA83 with Adobe RGB LED backlight
Some information has recently been released out about some upcoming Dell UltraSharp monitors which use wide colour gamut LED backlights. Unlike the big, bulky and generally problematic RGB-LED designs these use a white LED (WLED) design with special phosphors and additional green diodes to broaden their colour palette. LG Display are also producing their own WLED-backlit Adobe RGB monitor, the LG 27EA83. This model was actually first unveiled at IFA back in August 2012 but took a bit of a backseat with very little coverage and information available. As with other models announced at IFA we compiled a short list of upcoming monitors which included this model. LG now how an official product page online which sheds further light on the EA83 ‘ColorPrime’.
A colourful screen
The headline feature of the LG 27EA83 is its impressive colour performance which includes a 27” AH-IPS panel with 99% Adobe RGB coverage and full sRGB coverage. The monitor sports 8-bit colour per subpixel with additional FRC (Frame Rate Control) processing taking this up to 10-bit. LG have factory calibrated the displays for accurate colour representation in both the native colour gamut and the selectable sRGB emulation mode. The screen also features a programmable Look-Up Table (LUT) which allows the user to perform a hardware calibration of the monitor itself directly. Unlike a normal software calibration (using the graphics card’s LUT) this provides more precise adjustments which stick regardless of application. It isn’t yet clear which calibration devices will be supported but LG plan to release their branded ‘External Calibrator’ shortly which is guaranteed to work.
LG's own external calibrator
Other important aspects of the specification include a 2560 x 1440 (WQHD) resolution, 350 cd/m2 peak luminance and 6ms grey to grey response time. The screen surface is matte anti-glare but is of the reduced haze ‘semi glossy’ variety. The monitor comes mounted to an adjustable stand which offers 5 degrees of forwards tilt, 15 degrees of backwards tilt, height adjustment and pivot into portrait.
Slender LED technology
The screen is attached to the stand using a 100 x 100 VESA mount, meaning the stand can be removed and an alternative VESA-compatible solution used instead. The rear is dominated by a textured matte black plastic consisting of small raised triangles. The stand itself has a silver brushed metal-effect going on. As with the faux brushed metal at the front and on the stand this also seems to be constructed of plastic, though. Where metal is certainly used is on the ports of the monitor, all of which are located at the rear. When it comes to inputs and outputs the LG is a bit more barren than the Dell U2713H. There is a DisplayPort 1.2 input, HDMI, Dual-Link DVI-D, 3 USB 3.0 downstream, 1 USB 3.0 upstream and a headphone jack.
A textured rear
The screen is now available for an RRP of around the $1000 mark (£700) but actual prices could be lower due to retail competition. A model with ‘R’ suffix (27EA83R) is also available which uses a standard WLED backlight. This provides coverage of the sRGB colour space but does not give the monitor wide gamut capability. It is otherwise the same as the ‘base model’.
