Projectors… (again)
Hi folks, I know that various projector and monitoring solutions have been talked somewhat to death on this forum, but I’m once again doing that dance, and the landscape is always changing.
My research has led me to similar conclusions as the folks in this thread:
https://forums.creativecow.net/thread/277/6875#6881My top two candidates at this point are the new JVC RS65 and Projection Design’s Cineo 35 2.5K.
People’s experience with the JVC D-ILA projectors seem mixed. I’ve spoken with a few people who have finished films with them and love them, and others who hate them. The main problems seem to be potential for them to drift due to temperature changes, and “non-linearity” of the gamma response…
The cineo 35 2.5K is obviously a much better projector, but at a significantly higher price point (2-3x the price), and I’m hesitant to put down that type of money for something I’m not entirely sold on…
My hesitation around the Cineo 35 2.5K is that I’ve never used a single chip DLP, and haven’t heard great things about them. Also, the 2.5K resolution is a bit odd, I would only be using a 2K extraction from that.
In the past I have only used either the NEC is8 (or similar NEC 3 chip DLP), or a regular panasonic plasma (11 series or VT25).
Thanks for any feedback on the any of these projectors, or good alternatives!

Have you looked at the InFocus SP8602? it is a 1300 lumen 1080P single chip DLP which seems to perform well. I like the LcOS projectors but stability is definitely an issue, as I have a 11UK plasma I understand..
Most cinema 2K projectors are going to be DLP and running a DLP in a grading environment will be at least a bit stable. You still have to watch out for declining light output with projectors that are not Xenon or LED light source but that is a bit easier than having to calibrate regularly for color stability.

Hi Robert, what stability problem do you have?. Is not stable after 3 hours?, or 3 days, or 3 weeks?.
I think single chip DLP can be good for color grading, but is very bad for client because how can you explain the rainbow effect?. I know a DP that don’t like the rainbow effects because it cause headaches. I include old red evf.

I really like Plasma display’s over LCD for their much wider dynamic range and their wide viewing angles. The drawback to Plasma technology is that it is less stable over time and has to be re-calibrated more often. So until there is a 40-50″ OLED screen that does not cost six figures I will calibrate more often…
I personally do not have problems with seeing rainbows on single chip DLP projectors and many people do not. I also think that newer single chip DLP projectors with 6-segment higher speed color wheels have mostly eliminated rainbow effect.
That said the Projection Design LED single chip DLP projectors look interesting, no color wheel and super stable LED illumination..

but the stability problem is only with plasma?…
I was refering to what problem of stability do you have with LcOS projectors?.
Recalibration after a month is not a problem (for me), but recalibration after an hour can be an issue.

I have heard that Lcos projectors are less stable than DLP but maybe the newer ones are less so.

When I had a call with some of the Projection Design engineers and a reseller, there were still a lot of things being worked out with the cineo35 2.5K projector – they weren’t yet shipping a configuration with the LED light or SDI inputs. I haven’t heard from them since about availability…
As far as the LED source, I would really want to see it and test it before taking any claims about color accuracy at face value. I don’t actually have any reason to doubt that LED can provide a perfectly good wide gamut and stable replacement for Xenon or such, but cinematographers that have been using LEDs as lighting sources have come across very problematic characteristics of the light combined with digital capture… Daryn Okada did a study with the academy on solid state lighting… it might not apply here, but I would definitely want to see comparisons before settling on the projector that is using a non-standard technology.
My friend just picked up a RS60U – I was really impressed with this projector at NAB.
