ADI has released the latest addition to its G Series, the 19in G900, sporting a Hitachi CM901 shadow-mask Pure Flat Tube.
The screen has a flat exterior, although the inside of the tube has a distinct curvature. This has the irritating effect of reflecting the bezel surrounding the tube as well as causing double reflections. However, these are most visible when the unit is switched off.
The G900 is marketed as a high-end model, so we expected to find a selection of connectors around the back. But there are only captive D-SUB and mic output, although you can purchase a USB hub for £20 - this includes one upstream and four downstream ports.
The front of the unit has a plain fascia, sporting just three OSD controls, two dials for brightness and contrast, and the on/off switch. Using the OSD is easy but a description of what each control actually does would be useful. All the usual options for geometry are present including two for horizontal and vertical linearity.
As for colour, there are three preset colour temperatures and three others where the user can define the RGB levels individually. There are no colour convergence controls here - a shame, as vertical colour registration towards the outside of the display was off.
The G900 has a dot pitch of 0.25mm, a viewable diagonal of 18in and a maximum resolution of 1600 x 1200 at 75Hz. This is a little hard on the eyes and most will find 1,280 x 1,024 at 85Hz more suitable. Image quality is average, although the colour depth can't compete with most aperture-grille units. Focus also suffers in the corners.
Geometrically, the screen falls down on corner linearity: the top left and right corners appeared slightly irregular in the fine geometric linearity test, with adjustments having little effect. Power regulation could also be more controlled.
Overall, not a great showing, but with a price tag of £299 you could do worse.
