REVIEW: LG Flatron W2600HP Part 8
LG has equipped the W2600HP with an S-IPS panel which is also used in the NEC LCD2690WUXi according to the manufacturer. Colour control occurs via 8-Bit, so banding generally arises when software calibration is carried out more than in screens with 10, 12 or 14-Bit LUTs, where the colour range is retained when the colour channels are changed.
Despite, or perhaps because of the high factory setting for brightness of 334 cd/m² and 308 cd/m² after a two-hour warm-up period and the incredibly harsh, bright, strong colours, the image looks brilliant at first glance. Users who have worked on a monitor with a normal colour space until now will of course have to get used to the new strength of the colours.
Whilst white demonstrates a clear reddish hue in Rev. 1 and red surfaces look over-saturated and the image is a touch too unnatural, these problems have almost entirely been solved in Rev. 2. The contrast is 831:1 in the factory settings and 970:1 in User mode, both of them very good values for an S-IPS panel. After calibration to sRGB and adjustment of the brightness to 140 cd/m², our measuring devices came up with a contrast ratio of 1.174:1.
Colour gradients and test images generally demonstrated unusually strong banding on our Rev. Q test model. Rev. 1 models often collect several colour tones which are close to each other into one single colour. Even in normal use, gradients can be seen when photos are viewed, regardless of the image mode selected. It almost looks as though the dynamic contrast adjustment is constantly active.
With the newer Rev. 2 models, the banding and various other image control problems of the f-Engine have been corrected. With Rev. 2, the banding is a thing of the past: it is amazing what a little software can do!

The viewing angles on the LG W2600HP are very good. Only the brightness decreases as the viewing angle widens and the actual colour tone is retained. Towards the top, white becomes a touch more reddish, but otherwise the colour stability is excellent: even if we crick our necks on the computer chair, the image remains as it should be.
The lowest brightness without a reduction of the RGB channel is 168 cd/m² on our test model, which may be too much for some users. The LG W2600HP achieves a proud maximum value of 334 cd/m². The scope between the maximum and minimum brightness, at 166 cd/m², is sufficient in itself, but there should be more scope in the lower values.
The brightness distribution measured on our Rev. 1 test model is somewhat better than in the second model (Rev. 2), which is probably due to variation within the series with regard to the production data.
