Class A Commercial, Class B Residential. Different specs?

Shielding has a lot to do with it from what I understand. FCC classes them according to how much RF interference they'll emit. Yet another reason you should NOT use commercial displays in people's home.
Extra chance of interference (including your remote control system), usually worse line scalers, usually worse black levels, etc...
Not all commercial models exibit worse performance in all aspects, but there's a reason why their cheaper than their residential counterparts - the more of the cost difference, the more stuff is pulled out and/or made cheaper for that commercial model.

The scary spec is that the emissions are so high on commercial models that the FCC would not allow them in your home for fear that the length of exposure to the emissions over general TV usage could potentially get to dangerous levels... (I guess those traders on the floor of the NYSE under the full perimeter of plasma monitors and the guys in the airport terminals that stand at the ticket counters underneath the dozen plasma terminal screens for 8 hrs.+ each day are all screwed)

The reality is that everything else in your house from your flourescent lights over the workbench in the garage to the microwave emit far worse... but commercial models REALLY DO screw up IR.

Oh, and they usually don't have the right inputs unless you are using a scaler with it and are converting everything to RGBHV.

I cannot think of a commerical model, ( Hitachi, Sony, LG, Pioneer, Fujitsu, Panasonic commericial displays are all brands I have personal experience with ) that dispite having RGBHV inputs cannot have those inputs configured for component video. Even in the systems contracting world a DVD is still a DVD and I have never seen a RGBHV DVD. Moreover, ATSC high definition is a Y/Pb/Pr specificiation not a RGBHV specification.

There is often zero difference between the two different models save cosmetics and color of the bezel. With some brands the difference is indeed the electronics used to enhance video performance, especially the Hitachi and Pioneer commercial units ( with out the video card ) but often it comes down to built in ATSC tuners and non removable speakers and the certainty that you will have a serial protocol with the commercial but no rear connectivity at all with the consumer. The radiation specifications are a given. I have not measured them but by eye out of the box the Panasonic commercial displays out perform their less expensive ubiqutious consumer brethern by a lot. The equivalent models in both camps seem identical to my eye.

Many commercial plasmas are not user friendly. No discrete inputs or power, no shielding, horrible user interface.

I have to agree with what Allan has written. From a control, picture quality and half-life hour rating, commercial units are much better. It is rare that I just hang a plasma on a wall, hook cable tv to the unit and leave. Our customers usually have a surround system with many sources. The built-in ATSC tuners and speakers are just wasted money at that point. The one thing that I have experienced differently than most of you is that the commercial units we have installed interfere LESS with RF communications. Since a lot of the consumer branded plasmas start their life off as a commercial unit and get 're-worked' and re-badged, I dont really see the benefit. The systems contracting world is light years ahead of the residential world in setting standards for control. I dont recall ever running across a pro-grade plasma that did not have discretes or usable serial protocol. I cannot say the same for the residential grades.

Main difference is certainly emission levels. This is very noticeable in the Fujitsu models. Some of the commercial models like the Pioneers actually have fantastic features, over their residential counterparts, for calibration.

We sell the Panasonic D7 series Commercial they are very controllable. Full set of discrete's and rs232 and they use the same shield on Commercial and Residential so the emissions are the same. On top of that you can chose exactly what connections you want.
I wouldn’t use any thing else.

I don't know if I've ever seen a black vs. white thread like this.

MORE EMISSIONS -- less emissions

NO DISCRETES -- easily controlled

WRONG INPUTS -- just the ones you need

LOUSIER PIC -- look much better

MORE TASTE -- less filling

(I added the last one, but you get the point.)

more emissions


Commericaial often include discrete IR but not aways. They alwasy have a serial protocol. ALWAYS!


Inputs are user configurable. The deuxieum Rick was in error.




Actually depends on the unit. Consumer Fujitsu and Pioneer Elite have superior video electronics and better picture than commercial counterparts. Panasonic basicly the same assuming the same unit but commercial superior to many of the less expenisve consumer units.

Sony: The same

Hitachi: consumer units used to be better but I am not current with the latest consumer displays

LG: the same unit, different cosmetics. I assume they added some shielding to make it a consumer unit but the exact same unit otherwise. Rick: Thanks for the education concening quotes. Care to teach me how to post graphics files?

Personally I'd like my plasma to be installed at the local hospital (more filling, less taste)...

And my beer to be installed at the local pub.....(more taste, less filling)....

I don't quite get what your saying, but gawd do I want a beer.

Customer bought his own projector on the internet, the model suggested by his son. All looked pretty reasonable until he found it took fourteen button pushes to get to where he could change the video from "standard" to "sports" or "movie." Guess those boardrooms just don't need to go there that often.

Serial, serial, serial. You guys need to ditch IR and jump on the bidirectional band wagon. Take the Integra zone 2 issue I asked for help on. Turns out my guys wired the pool speakers to the zone 2 but did not tell me. All I had to do was send discrete zone 2 codes to the unit to turn on and off zone 2 and select the apporpriate input and employ a Truth Table ( Boolian logic folks, just google it ) and when both zone 2 and the main zone I send the surround channel to stereo and when zone 2 is off I return to the default setting for that input. No zone 2 ir code and then a power command. Commercial gear does not need a good IR protocol because no commercial contractor would be allowed to control it via one -way IR. I'll bet the projector the son recommended for his father had a very good serial protocol. No need to jump through IR hoops in a board room because RS-232 and not one-way IR was used. And even if you wished to use serial as a one - way commuication ( as you would if you used a Xantech serial product ) you can still take advantage of the many commands available in serial but not IR. The problem is that you guys are specifiying IR remotes and IR control systems so you are stuck with what ever codes you can get. And as all too many consumer displays but almost any other consumer gear have neither serial nor rear IR jacks you either need to use one of those crappy universal remotes or take apart the display and put the emitter inside the set. Now is not that a really intelligent thing for manufacturers to force upon us.

I think it's a blood plasma thing.
