Now with this sort of fine adjustment the LL-T2020-H is clearly aimed at the graphics professional, but is the actual panel up to it? Initial impressions under our tests are good, revealing a bright display that is evenly lit together with excellent colour purity. The 256-intenstiy greyscale ramp is very smooth and shows no signs of spurious colouration or banding. However, the colour ramp showed signs of slight compression in the red band of the scales and this is where the LL-T2020-H falls short if youâ€™re looking for a display that can rival a CRT. This compression also seemed to manifest itself in an ever-so slight reddish tone to our test photos, although with some delicate tweaking we were able to reduce this.
Apart from that, the rest of the tests were passed with flying colours, and despite the 25ms response time the LL-T2020 didnâ€™t suffer from any noticeable motion smearing when we analysed movie playback and general gameplay. When using an analogue signal the colour purity and vibrancy did drop a smidgen, but thatâ€™s pretty much the norm for this type of signal. Viewing angles were impressive in both planes too and over the extent of the display there was only a slight drop in illumination and a minimal colour shift when viewed from the extremities.
Overall, the Sharp LL-T2020 display is a fine 20.1in LCD that falls pretty much in the same category as the NEC unit in terms of performance, and like the NEC it carries with it a very high price tag.
On its own, the Sharp LL-T2020-H is a solid performing display with excellent image quality and a great set of controls. However, when itâ€™s compared to the opposition in this group test, the older USB 1.1 hub, debatable build quality and of course the high price ultimately impact on its desirability.
