Store Demonstation Mode on Panny Plasma?

post #1 of 8
Thread Starter 
On the one-time initial set-up screens on my Panasonic 60ST30, there is an option to set my viewing mode to either "home" or "store demonstration" modes. On previous televisions that I have owned, I have always selected "home," believing that store demonstation mode would introduce excessive brightness, very poor color processing, and who knows what other processing nightmares.

(Keep in mind, Store Demonstration Mode is different than "Vivid" picture mode).

However, my ST30 isn't quite bright enough for me. Calibrated I get only 19ftL in low panel mode and 30 ftL in mid. High panel brightness introduces massive amounts of noise and serious green push, so I don't use it.

I had all but resigned myself to the fact that this was as bright as the television was ever going to be (given the PQ compromises I am willing to make), but then I stumbled upon an article which suggested that "store demonstration" mode allowed additional power to be pushed to the panel to increase brightness.

So my question is: have any of you tried this? And if so, does store demonstration mode make the set brighter at the expense of overall PQ, or does it merely push more power to the panel and boost brightness without hosing up all PQ parameters in the process? One reason I am asking the question is becasue I know these Panny's have a brightness limiter designed to save power consumption and I'm wondering if store demonstration mode allows the owner to bypass this limiter.

If I don't hear from anyone, I will try it tonight. I'm just curious if any of you know anything about this setting.

Intriguing, can't wait to see the responses to this question. Also if it does increase the brightness without sacrificing picture quality how do you get back to the 1 time setup to select store demonstration mode?

I think you can just unplug the TV for 30 seconds or hold down the power button for 10 seconds (or however much time). I have not tried it yet though.

warning, this will erase any calibration except the drives and cuts 2 point grayscale.


From the service manual ---

6 Troubleshooting Guide

---

6.1. Check of the IIC bus lines

6.1.1. How to access

* Self-check indication only:
** Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [OK] button on the remote control for more than 3 seconds.

* Self-check indication and forced to factory shipment setting:
** Produce TV reception screen, and while pressing [VOLUME ( - )] button on the main unit, press [MENU] button on the remote control for more than 3 seconds.

6.1.2. Exit
Disconnect the AC cord from wall outlet.




...to reset the set, power on the tv,
hold the menu button on the remote and at the same time
hold down the volume minus button on the tv, after about 5 seconds
you will see a screen with information come up,
at this point hold down the power button on the front of
the set until it turns off, then unplug the main power for
30 seconds plug back up and it's like you unboxed it for the
first time.

This will reset all the user menu settings back to default,

I can't really comment on the picture setting differences for these modes but Store Demonstration mode, in general, usually puts widgets or graphics on the screen showing the features of the TV. I doubt you'd want that.

EDIT: For most TVs, Store Demo mode also resets the picture settings every 30 or so mins.

Well, it turns out you're right. I found a place in the user manual where it confirms that store mode sets the pic mode to VIVID and resets all the settings every so often.

At least now I know.

I work in a brightly lit tv showroom. I've never seen a single case where store demo mode gave a brighter picture than maxed out home settings.

If your new set isn't bright enough you have two alternatives--return it for something brighter (led/lcd) or control the ambient light in the room.

I disagree a bit, as things are typically not so cut and dry.

I had already managed to calibrate my display and thereby boost my OOTB brightness from 23 ftL (default on low panel mode) to 30 ftL (calibrated in mid panel mode) before ever making this post. Others in a similar situation will likely have similar options available to them.

In addition, there are plenty of other plasma sets that are CONSIDERABLY brighter than this one, so there is no reason for me to purchase an LCD unless I suddenly decide I am fond of their PQ for some other reason (I am not).

So, two more alternatives:

3) Get a brighter plasma
4) Resign myself to accepting the progress I've made thus far.

I'm likely going with option 4. 30ftL isn't horrible during the day, and while it certainly could be better (hence my initial post), it is already way better than the 19 ftL that I measured after completing my first calibration in low panel mode.
