If computer monitors were sold by the pound, then the Mitsubishi Diamond Pro 1000 would be one of the most expensive models on the market! Rick Maybury risks a double hernia to bring you the low down on this 21-inch heavyweight



Three quarters of the way down the feature list in the Mitsubishi Diamond Pro 1000 instruction book it says, and we quote, ‘Digital chassis design for lighter, more compact enclosure…’. The word ‘lighter’ caught our eye, having spent the best part of ten minutes struggling to get the beast out of its box and onto a table strong enough to support it’s 35.5 kg bulk! Normally the weight of a monitor is not something we’re particularly concerned about, but we’ll make an exception in this case, if only to warn anyone thinking of buying one to make sure they have a fit friend on hand to help install it.


It is well worth the effort, though the suggested selling price of just under £1400, is a tad steep side, even for a well-qualified 21-incher like this. However, before you make up your mind take a look at the specification and our performance findings. It is based around one of Mitsubishi’s 55cm Diamondtron display tubes, they’re very similar to Sony Trinitron CRTs, which means a near flat faceplate and the promise of a bright, accurate image. Dot pitch, or rather aperture pitch is an unremarkable 0.28 mm and the actual visible display is 50cm, or just over 19 inches. That kind of screen acreage puts it firmly into the serious user category, suitable for CAD/CAM, graphics and not forgetting computer video applications.


The Pro 1000 is capable of a maximum resolution of 1800 x 1440, though we suspect most applications and video cards will call for a 1600 x 1200 display. Microprocessor controlled auto-scan decides which of the ten preset standard resolution and refresh rate settings are most appropriate, or it can store up to 15 custom settings. It can handle all PC and MAC graphic schemes and will communicate with machines that support the VESA DDC1 and DDC2B protocols, enabling automatic set up. It is compliant with all current power management systems and emission limits, and it comes with a MAC adaptor.


Around the back there’s a standard 15-pin D-Sub socket, separate BNC sockets for RGB and synch signals, and a 9-pin mini DIN socket, for an optional serial connection. A button on the front panel switches between BNC and D-Sub inputs, so theoretically it could be connected to two PCs at once.


Apart from the main on/off switch all of the controls are on a small drop-down panel. Most of the user options are on a comprehensive on-screen display; it has adjustments for just about every picture and geometry parameter you can think of, plus a few more besides. If you don’t fancy fiddling with the controls just press the Auto-Cal button on the front panel, and the microchip minions inside the box will sort out the main display settings for you.



Shadows cast by two damping wires are just about visible on a bright white display; otherwise they’re not intrusive. As usual, following a 30-minute warm-up we used CheckScreen and N-Test monitor test programs, some lively game software and moving video on a range of resolution settings, to ferret out any anomalies, mis-aligment or design flaws. Focus is a major concern on a large screen, but this one was pin-sharp, right up to the edges of the display. Colour purity and convergence were both spot-on, resolution was excellent, the display is rock-solid and it has one of the most stable power supplies we’ve come across. In fact we couldn’t find a single thing to grumble about, image quality is simply brilliant.



It’s big, heavy and expensive but flexibility and ease of use are superb. Picture performance is outstanding, and if that’s your main concern then forget what we said about the price.
