The JVC DLA-Z1/RS4500 is a mixed bag. It impresses with comparatively superior performance in some respects only to disappoint with respect to others. Whether overall one considers that what is intended to be the new flagship projector delivers an acceptable minimum quality standard of video performance for its price tag of £35,000 we will present the salient facts and let you draw your own conclusions.

3.8 metres / 12.5 feet wide projection screen, with Seymour Screen Excellence Enlightor PRO Screen Material, within blacked-out room:


● Excellent out-of-the-box performance as compared with calibrated

● Razor sharp image due to superior lenses and associated hardware

● Superb colour performance and accuracy

● Laser dimming feature perceivably significantly enhances the contrast and black levels

● Initial firmware is very good indeed with comparatively very few issues, bugs, and/or malfunctions that need ironing out with subsequent firmware updates


● Disappointing native ON/OFF Contrast that is less than forecast by JVC, ranging from circa minimum 9,000:1 (with iris fully open) to maximum 40,000:1 (with iris fully closed)

● Disappointing calibrated light output that is less than forecast by JVC, with maximum circa 2,500 lumens (Rec.709) and 1,460 lumens (DCI-P3)

● Laser dimming feature performance inconsistent and problematic (Mode 2 particularly).

● Over 40% reduction in brightness output with BT.2020 colour filter.

● Prone to running hot and when it does the fans switch to 'turbo' mode and the operating noise hits the roof. MAXIMUM operating noise (when running hot): HIGH LASER [Max 70dB / 1m 63dB / 2m 56dB] | MEDIUM LASER [Max 63dB / 1m 57dB / 2m 54dB] | LOW LASER [Max 56dB / 1m 54dB / 2m 51dB]. That said, operating noise is easily remedied and becomes a non-issue via simply installing the projector into an air conditioned hush box/projection booth or outside the room.

● Outperformed in all respects with DCI-P3 colour, bar resolution, by 'lesser' models JVC DLA-X7500 (£6,100 RRP) and JVC DLA-X9500 (£9,100 RRP). Where with respect to resolution the difference is not significantly perceivably different being native 4K versus eShift 4K.

● Expensive.

We have received a great many requests for my opinions and feedback regarding highlights of what I discovered and/or learned from IFA in Berlin, particularly with respect to the new JVC DLA-Z1/RS4500 native 4K laser projector and SONY's new flagship range of televisions, namely the ZD9/Z9D . So here we go...


The advice I am giving everyone at the moment (including myself) is to wait just a couple of months and see what comes out of CES in Las Vegas, where all the remaining major and important announcements with respect to upcoming new native 4K HDR domestic home cinema projectors will transpire, and that’s with respect to ALL price brackets… It’s in only about 3 months’ time. And I have it on good authority that there’s going to be some major developments and/or announcements with respect to the domestic home cinema projectors, and that’s across all price brackets... And hence this is without a doubt the best timing regards when to decide which particular make and model of home cinema projector, myself included.

The JVC DLA-Z1/RS4500 at IFA was disappointingly only an alpha prototype, and so I am reserving judgement and my feedback/comments until after I see the actual production model, where the latest will be at CES 2017 in January 2017.

So like I said my advice to anyone and everyone, AV dealers and customers alike, is to hold fire and wait until then, because only then can anyone make a fully informed decision with all the salient facts.

Early adopters beware because this is one of those instances wherein you really don’t want to go charging ahead and purchase a projector only to discover just a couple of months later that you have made the wrong choice … So best to wait to see what’s announced and/or revealed at CES in 3 months’ time.


In short, the SONY ZD9/Z9D TVs are all absolutely A-M-A-Z-I-N-G !!!

Ladies and gentlemen if you are seeking and/or want to buy the indisputable absolute best TV in the world, here it is.

SONY’s ZD9/Z9D TVs are the only TVs currently in existence where absolute pitch blacks and absolute bright whites co-exist side-by-side together concomitantly… With black levels nearly on par with OLED's, but with circa FOUR times the peak luminosity; and without the numerous technological flaws that plague OLED TVs, including the tendency for shadow detail to be crushed and bright highlights to be blown out.  Consequently, the SONY’s ZD9/Z9D TVs deliver what is irrefutably the best HDR of any TV currently available.

And so with its new ZD9/Z9D flagship range of TVs SONY snatches the crown of ‘Best TVs in the World’ away from LG who mistakenly thought they had won it with their latest and best range of OLED TVs, which in fact trail a mile behind the video performance of SONY’s trump card.

And with the entry level UK model, namely the 65” KD-65ZD9, costing comparatively ‘only’ £3,999 RRP, whilst this is indeed pricey and beyond many peoples’ maximum budgets and affordability, when the £3,999 RRP price tag is compared with the other best and brightest 65” 4K Full-HDR TVs by other brands, including the likes of PANASONIC, SAMSUNG, and LG to name a few, this actually represents pretty good value for money, all things considered.

And see BELOW for some photos taken by yours truly of the SONY ZD9/Z9D in action, however, please bear in mind that photos being displayed on a video display other than an actual SONY ZD9/Z9D is not going to be showing you accurately nor do justice with respect to what it actually looks like in the flesh, but here you go:
