Light-speed liquid crystal

Fast pixel response time is vital when watching high-speed images on an LCD. ViewSonic claims to have cut this down to just 4ms, but the new 19in VX924 demonstrates that this isn't the whole story.

Like all sub-12ms monitors, the VX924 uses a 6-bit LCD panel. This means that dithering is used to produce certain colours, causing banding and pixelation in our colour/greyscale ramp tests and making this product unsuitable for colour-critical applications.

As well as using lower-viscosity liquid crystal, ViewSonic has reduced the LCD cell dimensions by 30 per cent. Although this reduces response time, it also reduces viewing angles, but these are still a reasonable 140 degrees horizontal and 130 degrees vertical.

It's an attractive display with minimal button clutter, but the stand lacks height adjustment and the silver trim adds to the bezel width - making side-by-side multi-monitor arrangements less effective. Contrast is respectable at 500:1, and the panel offers an ample peak brightness of 270cd/m2. Both VGA and DVI connections are supported, with the latter providing sharper end results.

VERDICT: It's pretty hard to spot the difference between this and a cheaper 8ms monitor with the naked eye, and you should consider this before making your decision. Laurence Grayson

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
