JVC’s industry’s highest native contrast ratio of 50,000:1 projector DLA-HD750

“JVC is the first major consumer electronics company to achieve certification in the projector category in the UK and Europe.” THZ

The industry’s highest* native contrast ratio of 50,000:1!

Changing the structural design of the optical section from a conventional L-shape to a straight configuration helped to reduce light leakage and by combining this new structure with a highly efficient lamp, a brightness of 900 lumens was realised. What’s more, integrating JVC’s proprietary D-ILA device with the wire-grid optical engine provided very high contrast. And, by equipping the newly developed lens with a fixed aperture to help eliminate unnecessary light that reduces contrast levels, it was possible for the DLA-HD750 to achieve the industry’s highest native contrast ratio of 50,000:1*.

Thanks to enhanced brightness created by the extended white peak as well as the wider dynamic range for a deeper black, images are vivid and full of depth, making them perfectly suited for all types of content, including movies, music video as well as live concert and sports programs.

* As of September 2008; native contrast of 50,000:1 for home theatre projector class (JVC survey).

High-performance 2x motorised zoom lens

The newly developed high-performance 2x zoom lens with motorised focus features a large diameter, all-glass lens system with 17 elements in 15 groups that includes 2 ED lenses to project a full HD image with exceptional depth. And to display the deepest black possible, this new high-precision lens is also equipped with a 16-step lens aperture that allows adjustment of brightness according to user preferences and usage environment. What’s more, the high-precision lens also reduces chromatic aberration and colour bleeding significantly.

Excellent colour rendition

The DLA-HD750 features Colour Management that interpolates colours individually by R, G, B, C, Y, or M, in three separate axes of colour phase, chroma saturation, and brightness. Up to three customised colour settings can be stored for future use.

Customised gamma control on-screen

Manual adjustment of gamma curve is possible via an on-screen display, allowing the viewer to adjust projector luminance levels by either increasing contrast in scenes that are too dark or dimming washed-out scenes to ensure precise brightness levels suited to individual preferences. Up to three settings can be adjusted and stored for future use.

Advanced video processor

Both projectors incorporate the HQV Reon-VX video processor developed by Silicon Optix. To ensure excellent image reproduction, this processor features precision I/P conversion and scaling with full 10-bit 4:4:4 signal processing as well as an HQV noise reduction function to block mosquito noise.

new BS Standard Wall Plate by Cablesson

July 3rd, 2009 — Oxford, UK. – UKHDMI— one of the United Kingdoms biggest distributors of HDMI Cables and Accessories, announced the release of British Standard HDMI Wall Plate.

Cablesson HDMI Wall Plate Dual Connector S/A - WhiteCablesson has gone ahead and released another HDMI Wall Plate this week. The new HDMI Wall Plate Dual Connector S/A in White is quite unique as it comes with dual connectors. We have not seen a dual wall plate in the market as yet with two different connects allowing the installer to connect two hdmi cables. The face plate requires no soldering and is equipped with two gold plated 19 pin HDMI Female connector on the front side, and two gold plated 19 pin Straight HDMI Female connector on the back side. It is to be used for fitment to a standard BS Mains Electrical (UK standard) back box at least 35mm deep, and supports HDMI 1.3/HDMI 1.4 standards. Cablesson recommends its Maestro CL3 HDMI Cable to be installed in wall as they are Low Smoke Zero Halogen. An Ivuna or Ikuna HDMI Cable can be used on the outside of the Face plate allowing a tight and seamless connectivity between both items. The wall plate includes screws.

Super HDMI Test

HDMI (high definition multimedia interface) cables are the must-have interconnection for the HD era. This streamlined high-tech system effectively replaces the old analogue SCART and supersedes separate component video and digital audio connections in one cable.

The specification has been evolving since launch and now stands at version 1.3. Most current HDMI cables should meet the v1.3 criteria, so even if you upgrade your hardware, good quality HDMI wiring should still be fine. It’s important to know if your cables can cope with high-bandwidth 1080p video signals, particularly if you need several metres’ worth.

Compatibility issues aside, a controversial aspect is that some people believe all HDMI cables are the same because they deal with digital signals that will either work perfectly or not at all. We put this to the test with a real-world trial. We used an HD DVD player, a 42in HD plasma TV and nine HDMI cables costing various amounts, taking price into consideration only after checking for picture quality. Can you really see a difference between them?

Better Cables Silver Serpent Reference

The BetterCables brand uses large silver conductors to minimise resistance and, it’s claimed, reduce the chance of digital dropouts that the cheaper cables can introduce. The Silver Serpent is also triple shielded to protect from interference, which can still affect a digital signal to some extent. Either way, the results are noticeably good, especially for colour fidelity, with superbly natural skin tones and subtlety in detail.
