Panasonic VT50 Self Vs. Pro Calibration - Page 3

Thanks, I'll give that a try on my next go-round.

Just tried autocal with v4.6.x, contrast and brightness displays don't seem to work, they look the same no matter how much +/- the C/B controls, is this a bug?
Of-course I can set C/B controls using my source disc.

If I buy the VT do I have to have it calibrated with fancy and expensive equipment if I'm just a dude that
Iikes to watch TV, BR movies, and play Xbox? Seems like this is for the SERIOUS videophiles. I'm sure it's awesome and all, but worth going to this length?

Thanks,

Jason

A full calibration will have no effect on your Xbox gaming, since you have to be in gaming mode to reduce the latency. Everything else though (TV, movies)? I'd say it's worth it.

I don't believe gaming mode on this TV has any effect on input lag (it's just a picture preset similar to custom mode in PQ pre-cal). So, using the calibrated settings will make the PQ optimized for games as well as TV and movies.

Pretty sure this is false. Yeah, it could all be in my head, but I can notice a significant difference when it's in game mode. The difference is not nearly as bad as an LCD, but it's definitely tangible.

has anyone tested input lag between the calibrated presets and game mode?

also, plasmas generally don't have input lag issues to begin with... so it shouldn't matter either way

All modern televisions have processing that goes on. Plasmas tend to have a little less of it in my experience, but they still have some. One of the reasons the "edge-enhancement" that was talked about during the shootout is non-defeatable is because Panasonic's engineers didn't provide a bypass for the Viera connect module, which induces the effect. All of these ASIC components induce some latency... the game mode just has the fewest number of them in play.

As for if anyone has measured game mode vs. other modes (such as ISF/Custom/THX), I have no idea... not that I've seen. Any reports, including mine, are purely anecdotal and qualitative. IMO it's nothing to worry about. The Game Mode is bright, it looks pretty good and you still have basic controls (brightness, contrast, color level, temperature), and the other modes, while they feel worse, still feel somewhat playable to me.

I set my Game Mode to WARM-2 and it doesn't look that far off from my calibrated ISF Day setting (so far... it's still a work in progress).

Hi,

With all due respect to SpectraCal their Auto cal does not work properly on any display. There are also many other parameters that the Auto cal does not adjust that you need to know how to manipulate to get the best results. There is no comparison between an Auto Cal done by a consumer and a Professional Calibration done by a pro with a lot of experience and reference level test gear.

Its not too bad with the Lumagen's. But then again, the Lumagen is not a display

Hi 703,

You are absolutely right! It does work with the Lumagen processors although I have had issues where I had to do the CMS manually in the processor.

Hi Kevin,

AVRs wouldn't have any effect if you turn off video processing, correct? I figured this was the same as "pass-through HDMI", and since it's a purely digital signal, I assumed that it would be no different than hooking it up directly to the Blu-Ray player. Is this accurate? FWIW, I have a Yamaha RX-A3000.

Thanks in advance.

BTW I enjoyed listening to your interview on Home Theater Geeks

Wait till you get a load of how CalMAN 5 autocal's gamut on a lumagen. It's good stuff.

To those who use the AVS 709 HD disc as a source, with CalMan: Have any of you tried the USB-UIRT control module with CalMan? I'm mainly curious as to how configurable it is. I seem to have better luck with the small APL patterns, for example. Is it possible to make changes like that in the flow with the automated Blu-Ray player control?

We support multiple disc players, plus you can edit the settings for IR control so that you can make sure that it works correctly with your player.

Once the IR codes are setup it's treated just like any other pattern generator.

On the other hand I don't know that using the IR control is much faster than managing it yourself.

Thanks Joel. I figured it would be easier for walking through greyscale calibration, especially since it should be more repeatable. The VT50's readings seem to be very much a "moving target", especially at the low end, so I find myself repeating the greyscale calibrating quite a bit. It would also be nice to see if the readings became more consistent once the slide transitions became more repeatable/automated- I always wonder if it's the amount of time I sit on a slide before I take a reading that is causing all of this variance.

But ultimately, I figured it would be nice if I could "walk away and grab a drink" while that's going, so that's why I was considering it .

Well then I don't think you'd be disappointed. That is the one thing it is good for.

I have a VT50 that I would like to calibrate, but also have a Front Projector (HD70) and Samsung LCD (46C6300) that I would like to calibrate in the future as well. Does it make sense for me to purchase or rent the equipment and try to do it myself? I am not looking for a perfect calibration, but imagine I can improve it significantly with a proper calibration using a decent meter (other than simply using cal discs and filters, etc).

Any recommendations? Are there economical meters that will give me good results and be compatible with the FP, Plasma, and LCD? I imagine I would find myself checking my computer monitors as well. I am happy to spend a decent amount of time learning how to do it before getting good results too.

Thanks

I wish I could use a IR device for my PS3 to automate the AVS patterns, but it is ahead of its time with only Bluetooth support. Will a Bluetooth controller be something considered in the future?

There are a number of IR to BT converters of the PS3.

As a side note, this is exactly why I went with a 360 instead of a PS3, as I use a Logitech Harmony remote, and I didn't want to bother with the adapters (well, there weren't any when I was looking at consoles for this generation). I don't know what Sony was thinking when they didn't include a $0.02 IR receiver.

yeah but the X360 can't do BD playback and I think the video player downscales resolution to 720p

First part is true, 2nd part isn't. Well, partially anyway. Both the 360 and the PS3 have many games that render at lower res (as low as 540p) and then upscale to 1080p. In fact, the PS3 has to upscale more often than the 360 IIRC, due to the weaker GPU on the PS3. There are lists out there of what the ACTUAL rendered resolutions of many of these games are. Sometimes ignorance is bliss

Anyway, sorry everyone- didn't want to turn this into a 360/PS3 debate .

I was referring to the PS3 as a media device/disc player, not as a video game console (I don't game much on it).

FWIW, I also have the X360, which I use purely for gaming.

Anybody know how to turn off Calman's OSD display in the DIY version 4.5 for a VT50 display??

ControlCal . Sorry, it's all but required for a VT50 flow at this point. It's a cheap license- it's worth every penny and then some.

There is a OSD toggle in the workflow just for that.

It is in the Panasonic workflow for turning the OSD on/off. Or you can open the DDC controls and put it in your workflow.

The VT50 doesn't have pattern generator built in, the duo does.

To calibrate a VT50 you'll need a pattern source.

Can anyone help me with the question above? This directly relates to self vs pro calibration.
