Introduction

With the W2420R, LG itself is entering into the high-end LCD product sector for ambitious image and video editing. Until now, panels from the manufacturer were often used in such devices, e.g. in the recently tested HP LP2480zx and Eizo CG243W, but the company had not produced its own model. The LG W2420R closes this gap and is presented as a screen for demanding users.

The 24-inch H-IPS panel is also integrated into the HP LP2480zx and is also illuminated with three-colour LEDs instead of CCFL tubes. LG promises playback with 10 bits per channel via the HDMI input (Version 1.3) (in the older versions, this was only possible in YCbCr with colour undersampling). In any case, the panel itself is reported to be controlled with suitable colour depth.

The LG W2420R is also suitably equipped in terms of electronics: with a programmable 12-Bit LUT and internal computational precision of 16 Bits, it does not need to hide in the face of the competition. With the integrated deinterlacer, playback of half-frame based signals is possible via HDMI. The software provided allows for hardware calibration with optional colour space emulation. LG also includes a compatible sensor in the form of a colorimeter.

All results published in this review were obtained via the digital output of an nVidia Geforce GTX 280 from Gainward. A Lumagen RadianceXD and an iScan VP50 were used to test the video functions. In addition, an OPPO DV-980H was used as a DVD player and a Sony S350E was used for Blu-rays. The colorimetric measurements were taken using a spectral photometer (EyeOne Pro). A colorimeter (X-Rite DTP94) was used to measure the minimum black value.
