I have been the proud owner of the 65ZT60 since October and thought I would share some of my experiences. It's a June build with (Knock wood) no dead pixels or cracks. As far as fan noise it's not an issue for me as the set is 2.5 ft from the back wall and I sit 13 feet away. I Also have fans installed in my equipment rack to keep my Conrad-Johnson tube amps warming up the room
Once my audio system gets going the Hafler DH-500 amp for my woofer columns has a MUCH louder fan in it so I can't even hear the ones in the PDP. The only time I hear them is when I'm watching the news in the morning with the volume very low. Here's a photo of where I spend most of my free time.
Yes, I do have a 7500K (Yes, I know 6500K is the standard but it helps compensate for the off-white paint) 94CRI 4ft Fluorescent tube on a bracket mounted to the back of the PDP with a dimmer control set to a 10% peak white level of the set.
I have been very pleased with this PDP. I was an ISF calibrator in the Los Angeles area for better than 15 years starting in the mid 90's (Even before DVD
) and attended the ISF training back when Joe Kane himself was the instructor. This was when he and Joel Silver first started the ISF and I concerned myself mainly with CRT Rear and Front projection systems all the way up to dual stack Vidikron Vision One and Runco 980's with Farouja line doublers and quadruplers (Very fun stuff!!). Anyway, I still keep up with this as a hobby and own Calman5 with their C6 Colorimeter (Complete with NIST calibration certificate dated 09/13). As many have pointed out this panel can be dialed to within better than 1 Delta E units of accuracy in the Grey Scale tracking and CMS management areas. However! We all know that this panel (Along with all the other Plasma's out there) suffer from ABL which leads me to "My" observations.
I have calibrated many of Sony's BVM's back in the day (Mainly the likes of the 1910's) back before HD but am pretty familiar with the way they look along with some very high end Home Theater systems over the years. Unfortunately this leaves these PDP's in the realm of subjectivity when it comes to Gamma
As has been discussed all over these forums the CRT BVM's (That most material is mastered on) has a Gamma very close to a 2.4 power curve. The ITU put forth a "Standard" for digital displays in 2011 with it's BT-1886 curve that closely follows a 2.4 power curve with the ability to allow for different black levels. I don't want to go into details here but it IS being adopted by the professional community as we speak. I don't have any experience with other PDP's but I do with this one.
I probably have in excess of 100 hours playing with this PDP (After breaking in for about 500 hrs. Currently has 1400 hrs). I did not break it in with the slides but with varying program material including mostly full screen but with a good amount of 1.33 and 2.4 material. My family uses the set for daily viewing so I leave it on the "Custom" setting with a lowered contrast level to help prevent IR. And no, "I" have not had an issue with IR with this unit, I watch very little sports but quite a bit of 2.40 film content.
I first started calibrating the set using the Day and Night ISFccc setting to compare different Gamma/Cal setups. I like using calibration Disc's versus generators as this helps to compensate for the entire video chain. Some of you that have been around long enough may remember this one.
Thought you may get a Kick out of that! Anyway, I use the Blu-Ray and HD-DVD versions of Joe Kane's Digital video Essentials and HD Basic's, AVSHD 709, Avia's, HQV's Benchmark and Stacey Spears and Don Munsil's HD Benchmark 1st and Second Editions disc's. And by the way: Stacey, if your out there we haven't spoke in years but would like to extend a warm Hello and Best wish's for the new year! I calibrated his rear projection set and we modified our Pioneer Elite CLD-97 LaserDisc players for RF Dolby Digital AC-3 outputs on my kitchen table some years ago.
Sorry, I'm getting side tracked.. The best "Subjective" results I have obtained are with the Small APL windows on the AVSHD disc followed by the S&M 2nd edition equal energy windows. I calibrated the ISF Night with the standard windows from the AVDHD disc and the ISF Day with the Low APL AVHD windows and in "My" opinion the Low APL Windows from the AVHD disc is the winner. Of course YMMV.
What's bothersome is if I measure the Gamma from the ISF Night setting (with the AVHD standard windows cal) with the Low APL windows the Gamma comes in at 2.67. If I measure the ISF Day setting (with the AVHD Low APL windows cal) with the Standard windows the Gamma comes in at 2.1 !! I really dislike ABL
So we know a Targeted Gamma is useless with Plasma's!! So, this PDP is THX certified which lead me to question how THX handle's ABL on "This" set? I started by adjusting the White Balance according to the Service Manual in the Service Mode. I then re-set the THX mode on the TV. I know that THX uses small windows in calibrating their sets (I do not know if they are just small or APL's or what size they actually are) but have read this elsewhere in these forums. I brought up the Small APL windows on the AVSHD 709 Disc and simply measured it:
It does not appear they are targeting BT-1886 but it's curious just "How Close" it falls into a standard 2.4 power curve with the Low APL windows! Now notice how the set comes out of black with the 10% stimulus level coming in at a Gamma point of 2.16. THX appears to want the Blacks to come out sooner just like BT-1886 with perhaps even a bit more extension. Of course all this is conjecture but this curve measures an average 2.42 Gamma with an almost perfect power level at 20, 30 and 50% Stimulus! Coincidence?
I calibrated my set with the same setting for ISF Day and Night aside from targeting a 2.2 power curve for Day and BT-1886 for night. My contrast is set at 60 which gives me 33.5 Foot Lamberts with the Small AVHD APL Windows (30 with the standard windows, again ABL...) which leaves me a bit of headroom above white (About 242 max where white is at 235). I have settled on these and have been quite happy.
Again, just my views, YMMV. Have spend enough time on this. Going to sit down and put a movie on
Thanks for listening to my rambling. Bob..
