The user color temp offers a single-point adjustment but there isn’t enough control range to achieve a 6500K average. By turning red to the max and zeroing out blue, I was able to reduce the average from 12,000K to around 8,000K. The change in DeltaE isn’t significant but the image looks far more natural. I also adjusted brightness and contrast to maximize dynamic range. That change improves gamma in the darker steps which lowers black levels and brings out more shadow detail.”
The NX9’s lens is flanked by two air vents that exhaust hot air from the chassis, while the back panel has a filter for intake. I was hoping the new, larger chassis would mean cooling refinements to reduce fan noise when the lamp is placed in High mode. (Typically, a larger chassis allows for larger fans that can run slower, resulting in less noise.) Fan noise is nearly undetectable in Low lamp mode, but this new design actually has a slightly higher noise level compared with previous JVC models when in High lamp mode. It’s low enough that the noise remains nearly undetectable when watching movies, although it can be heard during quieter passages. I definitely noticed it more than I did with the last two high-end Sony models I tested when running full light output. ”
As I’ve come to expect from Sony, the inclusion of a centrally mounted, fully motorized lens makes setup much easier than a lot of other projectors, which still offer only manual lens control. The lens has 2.06x zoom, a 1.36:1 – 2.79:1 throw ratio, with ±85 percent vertical and ±31 percent horizontal lens shift, offering a lot installation flexibility. Sony claims 1,800 lumens of light output, a 350,000:1 dynamic contrast ratio, support for all common types of 3D, HDR10 and HLG HDR modes, along with support for REC2020 color gamut. The 280-watt UHP lamp is rated for 6,000 hours.
I/O on the VW695 includes the two aforementioned 18Gbps HDMI 2.0b ports, a USB port for firmware updates, two 12-volt trigger ports, an RS-232 port for legacy system control, a LAN port for IP system control, and an IR port for a wired remote control.”
When it comes to judging the picture quality of either a television or projector, the impact of incorrect picture settings cannot be underestimated. For this reason, every display we review at StereoNET is ISF Calibrated before we make any judgements regarding picture quality.
All measurements of the Sony VPL-VW270ES were completed with an xrite i1Pro 2 spectroradiometer and x-rite i1 display Pro colourimeter (profiled with the i1Pro 2). The meters were tripod mounted, enabling measurements to be taken directly from the screen (Severtson 100” fixed CineGray screen).
Colour, Gamma, Grayscale and Luminance measurements were taken using 10% window patterns. Meter integration times were measured, and final readings taken from a mean of two readings to reduce anomalies.”
