post #1891 of 8511
Hi everyone. I just got my G20. This is my first Plasma. My last TV I bought was about 3 years ago and it was a Samsung LCD.

So I have heard to keep the contrast and brightness at 50% or lower for the first 200 hours to help with burn in.

Any other tips to get the most out of this TV. Will I pleased with my choice of going with the G20.

Also which mode is best to watch HDTV and Blu-ray in? THX mode?

Can anyone recommend any good calibration settings.

Do you think that is too much light for a plasma to be used in the room?

I have the same layout as you but with no entertainment center cabinets. What's worse is my windows are south-facing and run along most of the south wall. I used to have a tube TV and its screen was so reflective, it was difficult to use during the day. That light also affects my G20, but the AR coat is so good, its significantly more usable. The new generation Panny plasmas are said to be noticeably brighter than previous models.

See post #3:

For BD's most folks are using THX. For HDTV, people are reporting mixed preferences ... custom, standard, THX. Just go with what you like.

"Almost fixed" in the sense that I don't notice it as much. Just toying around with brightness and other misc. settings along with toying around with D-Nice's presets he created.

I can get into the service menu but then I have no idea how to get to the place where you do the offsets. I've run the slides and have everything done except the offsets because I don't know how to navigate/enter in. I tried Post 1541 and it had a broken link that was supposed to help.

Almost total newbie.

Afraid I may have already unintentionally altered some settings.


Any help is greatly appreciated.

Both TV and PS3 are HDMI 1.3a , but my receiver which will be acting as a pasthrough is only HDMI 1.2a

Given the specs below, will I lose any quality if I go through my receiver?

Namely Auto-Lipsync Correction feature (8.3.2, 8.9) & xvYCC Enhanced Colorimetry (6.7.2.3) ?

Obviously for sound I'll just go with LPCM from the PS3, but my question is will my TV be getting a lesser quality picture because my receiver is 1.2a only? If I go directly from the PS3 to TV, my understanding is the optical output on the TV downgrades itself to 2.0 only? and even if it was 5.1, i'd still not get TrueHD...

Ok, I used #6168 off of forum "New Panasonic THX Certified..." and figured out basically what I needed to do.

My THX went from: My Custom went from:

R-DRV: FD to FC (-1) FC to FB (-1)
G-DRV: FF to F7 (-8) F7 to EF (-8)
B-DRV: 7B to 7F (+4) 7F to 83 (+4)
R-CUT: 7C to 74 (-8) 72 to 6A (-8)
G-CUT: No Change No Change
B-CUT: 7F to 82 (+3) 82 to 85 (+3)


I was wondering if someone has posted the original VIVID settings? I think I unintentionally was changing these and was able to reverse out of it ONLY because you all reiterated to write everything down. I am not sure though if I got my VIVID Rcut setting back to normal. I think it should be 7A without any changes but trying to confirm.

I got a 54G20 and did the D-Nice method with the appropriate slides. It looks great to me but I'm obviously not into this as much as you guys but I appreciate the great help. I've learned a ton really.

G20/G25 is a great, cost effective set. There is no perfect TV.

Not to mention there are 50 reports of rising black levels here on AVS when Panasonic made 6 million TVs last year...... Want to see defects, scroll over into the LCD threads.

There's a PDF floating around with SM info that's widely referenced in these forums, I assume that's what you found.

I don't recall off the top of my head, but weren't the DRV and CUT parameters independent of the mode (e.g. THX, Vivid, Custom, etc)? I seem to recall they were only a function of the color temp and the resolution (SD or HD).

To test this, just look at the DRV & CUT values using the same resolution (either SD or HD) and the same warm temp, but with different modes. If the WB adjustments are independent of mode, then you'll see they have the same values in, say for example, THX/Cinema and Vivid. In that case, no worries. If the WB adjust values are different in THX/Cinema and Vivid, then I'm wrong and you're current thinking is correct.

Thanks Fmzip, that's way easier than i thought.
post #1901 of 8511
Just got my G-20 yesterday - I have to say D-Nice's THX settings look really good in my room. I didn't get into the pro controls but I was really happy with the picture during Lost last night so I don't know if I am going to mess with them.

Just wanted to say - thanks for providing that info!

I just got my 3rd set and I am very satisfied! There's very minimal buzzing than the previous sets so I think its a hit or miss. The difference between this set is that it has no sticker logos on the front and it was manufactured in April. I'm guessing newer sets do not buzz as much?

So cnet got a .007 fL black level for the g20 and after 100 hours, the black level is still .007 fL. Let's see how long it lasts.

They also measured .001 for the Kuro and LG 8500, .016 for a V10 at 1200 hours, .018 for a samsung b650 (strange, I thought these were supposed to be lower?), and .024 for a LG pk 750.

Curious about the 2:3 pulldown in 60hz mode. Does anybody have big problems with judder? Does it affect your viewing enjoyment, or is it smooth for the most part?
post #1906 of 8511
I just bought a 42" G25 and an upconverting DVD player, a $60 Sony from Costco...I did a comparison test, watched a DVD clip with an HDMI connection then with a composite connection, no difference in PQ. I'm confused, does the G25 upconvert DVDs? Was it a waste to buy an upconverting DVD player?

I don't want a BD player yet, but I didn't realize an old standard DVD player would have been fine until I do get one next year.

It depends on the upconverting DVD player and how good of a job it does. By the way, if you can dish out $60 for a DVD player, why not pay another $60 for a blu-ray player that will upconvert better as well as play blu-ray movies?

I tried my non-upconverting 480p CV output DVD player (also a Sony from Costco) on my 46G25 and it looked pretty bad using just the G25's capabilities. The upconverting in my Sony 360 BD player is far superior. 2009 model year BD players like the 360 can be found at crazy clearance prices. You could probably find one for not a whole lot more than that upconverting DVD player to tide you over and give you BD capability.

I guess it would depend on their lighting conditions.

Hey all, just purchased a G20 today and will receive it on Friday.

I spent an hour today on the phone with Panasonic prior to purchase it and had asked many specific questions, particularly about black levels.

The tech agent stated to me 100% absolutely positively the 2010 models do not have the lower black level issues. I insisted I heard otherwise, and she put me on hold and confirmed with a 'specialized tech' for the G20/25 series.

You should have told her to email you a guarantee that the black levels won't rise. Her 'specialized tech' is probably a marketing manager. Their statement conflicts with Panasonic's official statement some months back that this is how the TV was designed, and that the 2010 models will do the same thing only the blacks will rise more gradually than the 2009 models did.

I just picked up this set today and havent watched anything on it yet ( doing break in stuff ) but I was a lil disappointed that CNET found that this TV cannot handle 1080p/24 material.

Please pardon my ignorance, but what is 1080p/24 material?
post #1915 of 8511
24 frame per second is the film frame rate and most (all?) film sourced Bluray discs are encoded at that frame rate.

60 frames per second is the video display rate on most TVs.

Since 60/24 is not an integeral number, there is a motion artifact associate with going from 24 to 60 frames per second. Since they usually show one frame twice and the next frame 3 times (and repeat).

People would prefer to have 24 fps output to avoid this artifact. The 24 can be multiplied to 48, 96 or even 120 without adding such artifacts.

In simple terms, a 24p output into a monitor or projector that can display it, gives smoother motion for movies.

full resolution display, playing at 24 frames per second. Basically what most Blu-Ray movies' native displays are.

I'm curious about the Panasonic though. If you turn off 24p on your blu-ray player, how is the image displayed on screen? Is it converted into 60p? Will it look more or less as it does on my CRT right now (which does not accept 24p)?
post #1917 of 8511
So then do any G20/25 owners notice this "horrible" flicker (Cnet mentioned) in 48hz mode with blu-ray? I didn't notice any personally when viewing one the other day on a Panasonic Plasma.

yes it will be displayed at 60hz on the TV. like I said its a little disappointing and not a deal breaker yet (heavy flicker is a deal breaker though.) I find it a lil rediculous that 1080p/24 will work on their higher end models and not the G20 but I guess panasonic would be giving us too much at this price point

I just want to say that there is a whole lot of hand-wringing in this thread.

I go back to the beginning with big screen TV, back to the first Advent and Henry Kloss front projectors. For the last seven years, I've been watching HDTV on a Sony CRT rear projection TV. I took delivery of a 50 inch G20 yesterday and -- good lord -- the picture on this thing in THX mode is nothing short of stunning.

To be able to plug in a TV, flip it on, and select a factory THX setting that is this good out of the box? Amazing.

Sometimes I think these forums lose sight of the forest through the trees, getting caught up in minutia of black levels and this or that arcane specification.

Arcane according to you. Im not saying that it is not a beautiful looking set but not being able to display 1080p/24 properly is disappointing (especially flicker.) There is alot of cheaper sets out there that can display that format. Im not trying to beat a dead horse but I have a pretty large BluRay collection and I happen to like the cadence of 24Hz
