Relisys RLP2000 LCD Projector Review - Relisys RLP2000 Review


What’s curious about this projector is that the fan system appears to introduce a degree of internal vibration that’s transferred to either the LCD panels or the lamp, causing pixel movement in the projected image. This is particularly noticeable towards the top half of the projection, making static images look slightly wobbly. Ironically, this motion has a positive side effect in that it helps to reduce the ‘screendoor’ effect by blurring the gaps between the pixel groups, so it’s not all bad (though we’re pretty sure it’s not deliberate, either).

A surprise addition to this projector is the Faroudja DCDi signal processing unit, which has previously been limited to the higher end of the home entertainment market. This hardware employs a set of motion adaptive algorithms to significantly improve the image quality of interlaced video as it’s being shown on this progressive scan display, creating an interpolated image that massively reduces unwanted artefacts like jagged edges during playback. Add this to the impressive colour reproduction of the RLP2000 and you’d have a very good home cinema system – although you’d have to do something about the low contrast ratio to make it a great one.

Back to the business side of things and presenters will appreciate the remote control’s wireless mouse function, as well as the integrated laser pointer, digital zoom, freeze frame and instant blank functions. The operating noise made by the RLP2000 is a fairly imposing 37dBa (though without the kind of high frequency additions that made the PJ551 so difficult to be close to), and this drops to a more acceptable 34dBa in economy mode (along with the peak brightness level). A wide range of image adjustments are offered, including the mandatory brightness and contrast, but also black level, colour temperature, sharpness, saturation, hue and flesh tone. You’ll get around 2,000 hours out of the lamp before it needs replacing, and a pair of 1W speakers offer basic, if not especially useful, audio support.


Despite being offered at a very reasonable price for a projector of this specification, the RLP2000 doesn’t have the market entirely to itself. There are similarly-priced products from manufacturers like Hewlett-Packard and InFocus, which offer the same level of brightness and contrast as this one, and which may not have the trembling pixel issue that we found. If it wasn’t for this side of the RLP2000’s performance, we’d probably be recommending it whole-heartedly, as it is, we have to recommend that you try and see it in action for yourself before making that purchase decision.
