It’s been nearly a full decade since I built my dedicated home theatre. Since that day, it keeps evolving. It was first an LCD HD theatre, than 3D, then I added some upgrades to the subwoofer, including added DSPeaker Antimode 8033s, speakers, projection screen, Dolby Atmos and DTS:X. The latest upgrade is full-spec UHD with Wide Color Gamut and High Dynamic Range. That’s when I procured a JVC X750R projector.

As great as it was, I still had to change between the HDR and SDR settings manually, and the projector took an awfully long time to do a handshake. It also was not bright enough to produce an acceptable HDR picture. So although I only had my JVC X750R for a couple of years, I decided to upgrade to the JVC RS540, which is equivalent to the X790R.

In terms of chassis and physical looks, the RS540 is virtually identical to my old X750R; although it adds some gold touches that I can live without.

Colour Management

As mentioned in many previous articles, as well as in various discussion forums and through my Tweets (@davidsusilo), 4K/UHD video is about more than just increased picture resolution. One of the other enhancements is Wide Colour Gamut (colour space). A wider colour gamut means the resulting image includes a more accurate colour palette.

HDTV uses a limited colour gamut that’s defined by the ITU Rec 709. For UHD, ITU has defined an extremely Wide Color Gamut as part of its Recommendation 2020, and the Ultra HD Blu-ray Disc system has adopted REC 2020 as the ‘container’ for conveying a Wider Color Gamut.

For now and the foreseeable future, the movie studios plan to release their Ultra HD Blu-ray titles using the colour gamut already being used by the digital cinema industry, and that is called DCI-P3. And the JVC projector can do virtually 100% of the entire DCI-P3 colour space using its internal colour filter, which is what you see at the movie theatres.

Calibration of the Unit

Calibration using Calman and the associated meters was a blast. It’s so simple, it’s almost automatic, actually. As a calibrator, I was surprised that the THX preset, with a few tweaks, resulted in a fairly accurate result. In fact, this is the most accurate projector preset I’ve encountered to date – even more accurate than my previous JVC X750R. Of course, for the utmost accuracy, especially in the HDR department, a professional calibration is still required. Just like with any 4K projector display, the green tends to be overshot by too much.

Convergence is also pretty much bang-on right out of the box – I spent less than 20 minutes spent perfecting it. Even the previous “personal” best (JVC X750R) still took nearly an hour to do.

In fact, just a couple of weeks ago, I calibrated a $12,000+ projector, and it took me nearly two hours to perfect its convergence. To me, it is not so much about having the convergence be correct out of the box, but more of a testament to the quality control done by JVC at its factory. No wonder they call their delivery system a “4K Precision Image.”

Further, lens distortion is virtually nil. When set up properly, I had to work my eyes extremely hard to find the distortion of the lens, which usually happens around the corners and edges of the screen. Without my laser level, I couldn’t find the errors. Even as a person who is extremely sensitive to chromatic aberration, I couldn’t find the chromatic abberation unless I concentrated and truly looked for it during a movie playback.

With such brightness, accuracy, quality and the relatively low price of $8,000, only one word can describe this projector: AMAZING
