CRT - Mitsubishi Diamond Pro 930SB

The 19“ NEC-Mitsubishi Diamond Pro 930SB is one of two aperture grille monitors in this group test that offers enhanced brightness modes for viewing images and graphics. Similar to Iiyama’s High Brightness mode, the SuperBright DiamondTron technology of the Pro 930SB can be switched on and off at the touch of a button to provide brightness values that are better suited to viewing moving images such as DVDs. The SuperBright mode can also be activated and fine tuned by a software tool, although this is not included with the monitor and has to be downloaded from the NEC-Mitsubishi website.

The Diamond Pro 930SB has a recommended resolution of 1,280 x 1,024 at 85Hz although flicker free resolutions up to 1,920 x 1,440 at 73Hz are also achievable. A stylish silver front bezel and angular chassis both contribute to the monitor’s distinctive appearance, although the sleek lines are somewhat interrupted by the row of seven menu buttons along the front fascia.

The OSD menu system is fairly comprehensive with the usual array of adjustments for position, size and geometry as well as more sophisticated controls for colour temperature, colour convergence and an sRGB mode. The monitor is also compatible with NEC-Mitsubishi’s NaViSet software that allows users of Windows 2000 or XP to adjust the monitor settings by means of the keyboard and mouse instead of using the OSD controls. However, you’ll once again need to take a trip to the website to download it.

There are no USB ports or speakers incorporated into the 930SB and we also found the base extremely stiff to rotate, so much so that we couldn’t turn the unit with just one hand. We were pleased to find that power and signal connections at the rear of the screen were recessed, although the only means of video connectivity is via a single captive D-SUB cable. While not a major problem, this could become an issue if a fault develops with the signal cable.

Picture quality was generally very good. Images on the monitor were sharp and precise and colour scales appeared smooth with even intensity. Streaking and ghosting were minimal, and there were no signs of blooming, even when the SuperBright modes are selected. The same could not be said for screen regulation, which was average with some discernible movement over the entire screen.
We found no evidence of pincushioning, but the top of the display showed upward barrelling that could not be corrected using the OSD controls. Furthermore, there were some slight distortions in linearity in the upper left quadrant of the screen that were difficult to correct using the linearity controls.
On the plus side, colour registration was commendable in both the horizontal and vertical planes and colour purity was excellent for each RGB channel. There were also no signs of background interference.

Verdict
Overall, the Diamond Pro 930SB boasts a stylish appearance and like the Iiyama and ViewSonic it’s also geared towards multimedia applications with it’s extra levels in brightness and contrast. However it’s quite a pricey unit considering it lacks a USB hub, BNC connectors or speakers, and you can’t really say its general image quality is any better than the Philips or Iiyama.
