I'm about to purchase a new 60" GT50 and have the option of spending $150 (supposedly it's normally $300) to have them include "professional" calibration. It's my first plasma and I'm new to the whole calibration thing. Is it worth spending $150 to have this done, or is it good enough to play with the settings myself and experiment with settings found online?


Any feedback would be greatly appreciated.

$150 for a professional calibration sounds cheap to me. This wouldn't be at BB by any chance would it? Worth it is only something that you can decide. For me, if I spent whatever you did (will) on a GT50 I'd seriously think about getting it calibrated, but not by BB. It should cost anywhere from $300 - $500 depending on who does it and should take a couple of hours to complete. See if you can take the set home first and watch it for a period of time (a week maybe) before taking them up on the calibration offer. You may find that the pq is just fine for you. It all depends on how discriminating your are and if you really want your set to adhere to rec.709 video standards, which for some, is very important.

Thanks for that. It's not BB, but it's FutureShop (Canadian) which is owned by BB, so essentially it's BB, which is why I'm dubious about how professional the calibration would be.


Would you expect there to be a lot of difference between different TV sets of the same model? I know local cable can be highly variable, but in terms of watching Blu-Rays on it, I would have thought that the calibration settings would be pretty similar across sets of the same model, which is why I was thinking I could probably just get the settings off the web...

A $150 calibration isn't a "professional" calibration, it's a glorified TV adjustment. A proper ISF calibration by an independent calibrator will cost about 3 times more, but he''ll spend at least four times longer than the BB/FS "TV adjuster" guy is allowed to spend on your TV and you'll get a much better result. It's generally recommended to NOT let BB/FS/Geek Squad calibrate your TV. I'd pay more and let a pro do it properly.


I've spent the past week aging the panel on my new GT50 and have seen the PQ improve quite a bit in that period. Now that the panel has pretty much settled in (120 hours so far) i've been experimenting with the settings and trying to learn them and sometimes i get the TV looking pretty good, then i screw it all up and have to start over. It's kinda fun

Thanks, Randy, that's just what I needed to hear. I will pass on the BB/FS calibration and decide later if I need to go the pro route. Can't wait to get the GT50, hoping to have it on Tuesday! It's replacing my 250 pound 36" Sony XBR Trinitron CRT purchased about 12 years ago

What Randy said was true. I'd play around with the settings first and see how they interact with each other. It's a great way to learn about your new set. You can always get a calibration disk and at the very least, set the basics (contrast, brightness, aspect, color, etc) and get it even better. You won't have a "calibrated" set but your pq should be better than default. Just write down first what your settings are so you don't end up like Randy (myself and others included) screwing things up. And to your question as to differences between the same model, yes, there can be a big difference so that's why using someone else's settings is not always a good idea in case that's what you were thinking. Component variances, viewing environment all play a part in calibration.

Thanks for the tips! I think I'll take photos of the settings as I go along to keep track. My old set just had brightness, color, and contrast to work with, so I think I'm going to be in for a shock when the GT50 arrives

Spend $25 and get yourself a Spears & Munsil calibration disc, or DVE BD disc, or even download the free one on this forum. You'll get just as good, if not better results than a Best Buy "calibration". Also, playing around with settings isn't calibration.


Calibration is by definition:
"...a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.


The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated."

The futureshop website actually lists it as an ISF calibration and they apparently provide before and after reports, so I can only assume that they actually do a calibration and they don't just tweak it using a calibration disc. I do question the quality of their calibrations and their equipment though. Since THX mode is pretty decent already, a low quality calibration will make a small difference, so I agree with just getting a calibration disc. Another one that I would recommend is the Disney World of Wonder disc; it's more instructional than the other two mentioned so it's better for beginners.

I just recently got the DVE disc and think it explains things for too long (but fortunately has shortcuts). How does WoW go beyond the instructional level of the DVE?

I haven't used any of them, so I dunno to be honest. Just from what I've heard, Disney WoW is easier to use and is targeted more towards beginners compared to Spears & Munsil. Not sure exactly how DVE compares.

I like the AVS HD709 disk. It's a little more in depth than WoW, especially if you dl the docs ,and there is a nice little video by the HDNation guys that explains the basics. And it's free

I have the DVE and WOW


In my opinion WOW is easier to use and navigate. However it does not go as in depth and has no history lesson like DVE does. WOW also has much better gamma chart and explanation plus they reference starts and checkered pattern move so its easier to see them. DVE however has a 3 color paper filter while WOW only has a one. Not sure if this makes a difference somewhere, but there is my take.

I'm probably wading into dangerous waters here but I've always been under the impression that the paper filters were not that accurate because there is no way to guarantee their accuracy at that given wavelength consistently from batch to batch. Some tv's have built-in color filters (like my LG) that can be used instead. Of course there is no way to guarantee the accuracy of the built-in filters as well but they are internal to the display device.

I'm wondering if an ISF Calibration can improve sharpness and facial detail? My new 50GT50 is definitely softer than my 46G10 was, and it's not just because the screen is 4" larger. I've fiddled with the Pro Settings menu and i just can't get this TV to look as crisp as my G10 and it's starting to bug me. The softness is much more apparent on the 720p channels than it is on the 1080i channels.

I'm getting my GT50 calibrated for work reasons (as-good-as-I-can-get qc viewing of feature film titles and vfx before I deliver). If I didn't need a pro calibration for work I would ...


Get the Spears and Muncil disc and use it two or three times with a week's time in between, this gives your eyes/visual-memory a chance to "refresh". After that, if the picture looked good to me I wouldn't bother with a pro calibration.


I've used both the Disney WOW disc and the Spears And Muncil (an updated version coming late summer that I'd wait for!).

- I would agree that the Disney WOW is easier to use and is pretty good for color/contrast, but it's definitely weak on the geometrics side.

- The Spears and Muncil is more technical but I think they do a good job of walking you through it - the first time will take you longer than the Disney WOW disc, but the results cover/improve more visual ground.

Geometrics have a lot to do with detail/softness, but color/contrast also affects it more than might be obvious. Edges are tight, or abrupt, transitions between different colors and luminance levels. A good calibration smooths and clarifies all color/luminance transitions. The same tweaks that improve banding issues - i.e. large area color/luminance transitions - typically improve detail also (maybe think of it as "dirty" transitions vs "clean" transitions).


I'm guessing some HT calibrators only deal with color/contrast. Just ask up front if they also examine/tweak geometrics if you want to cover your bases. Both the calibrators I've seen (at work and at home) addressed both color/contrast and geometrics.


I'm also guessing any geometric adjustments would be in the service menus - just got my GT50 yesterday so I haven't had a chance to dig into it those yet. Not even sure if I will
