Trying to get best picture out of my HDTV

Hey guys, I posted this question in another forum and someone told me I should do the same here. If anyone could help it'd be much appreciated.

I just bought a new HDTV (30" Panasonic) for my room and hooked it up. I have a HDTV box hooked up with Component Inputs and I hooked up my progressive scan dvd player to component inputs also. The picture is great but for some reason I feel like there's something more to do. I don't know if it's just the matter of detail that you see now but it appears as if some colors are a little "noisy", sort of like they have a little bit of static in them. Maybe I'm just being paranoid. I set up the dvd player to progressive scan on a 16:9 tv so it appears as if all the settings are ok. I have the sharpness on the tv up pretty high (could that do it?). Anyways, if anyone has had any success setting up a hdtv then it would be greatly appreciated if you shared your knowledge.

Thanks in advance.

Manny

Yes, having the sharpness too high will probably do that. Best thing to do is buy the Digital Video Essentials DVD from Amazon (about $20). It will enable you to optimise the DVD input and indicate whether anything 'professional' needs to be done.

There are several things to look at:

1. Are you using a surge suppressor? And if so, are you running any satellite or cable lines through it?

2. Is the noise present on all modes; Satellite, cable, OTA HD, and DVD? Are you driving it through a a/v receiver?

#. When you go to blue screen ( no i/p to tv) is the noise present on the picture tube?

yes i have the tv hooked up to a monster surge protector

the noise isn't all that noticable. i would say that it's probably more present in dvd's but even then it's not that noticable

i boughtt he avia home theater setup disc so once i receive that i'll give some more updates

First, I want to congratulate you on making a very wise decision in choosing the Panasonic HDTV CRT. You've gotten very good advice so far. Turn down the sharpness, it should be less than 20-30%. Use a calibrating DVD if you want to be precise. Since you have a surge protector, chances of unequal voltage is unlikely. If turning down the sharpness isn't satisfactory, try new component cables. Otherwise, why aren't you using a digital DVI-HDMI connection? Generally, there isn't significant difference in using component (analogue) and DVI/HDMI cables (digital), but I suspect you probably have superior stereoscopic vision allowing you to perceive the imperfections of the analogue component cable conversion. I use DVI/HDMI for both my Panasonic PT43LC14 and my Toshiba 26HF85 with slight detectable improvement of digital vs. component connection. On both TVs, the component connection requires turning down the sharpness and color significantly more otherwise the color is too oversaturated.

Emsurfer, its analog, not analogue.

Im a pro installer and setup who also has a Panasonic Tau CRT HDTV. The proper setup is the standard mode.

Picture setting is between 31%(midpoint)and 45%
Brightness is the same, between 31%(midpoint) and 45%
Color is 31%(midpoint) to 25%
Sharpness is 31% (midpoint)
Tint is 31% (midpoint)

Color temp is normal
Video noise reduction is off ( it can cause loss of detail )
The Y/C Comb filter will automatically be off (when displaying high def signal)
Color matrix will be automatically be on HD when displaying a high def signal )
VM could be on or off ( depends on your preference )
MPEG NR will be off ( also to your preference )

This is only for high def signals, not for the dvd signal. When using the DVD, set that for the movie setting. Thats a quote from the tune up dvd itself. The color, the brightness, and the picture settings are pretty accurate. The only way to be 100% accurate is to have a pro do it. Check out the calibration forum.

Mike, it's "it's", not "its." :D

Also, both spellings of analog are in my dictionary.

good to know. by the way, congrates on your successful Panasonic purchase Don G.

hey mike thanks for the tips...i tried those settings and the picture definetly looks a little bit better....i already purchased the avia home theater set up so that should arrive shortly through the mail...thanks for the suggestions though since they definetly seemed to help

now another problem that i noticed (it appears to be a signal problem on nbc's side) it appears to show a tiny bit of static on the top part of the picture....it's kinda hard to explain but it appears to be a line on the top of the picture that's flickering and "staticy"....it seems to only happen with nbc's hd signal...all the other hd channel's work the same....i don't know what it is but i assume i'll just get used to it or it will be fixed on their end at some point

emsurfer...thanks for the suggestions also...i just bought the tv and between that and a few other things i don't really want to spend any more money for the month so I plan to buy an hdmi cable within a few weeks....im definetly planning to upgrade

Since you want to get "the best picture"...

Do everything listed above except springing for high dollar cables filled with pollihollowthermofuzz. I've tested and posted the results elsewhere on this forum and the difference between stock component routed away from rf interference sources is negligible.

Since you are dealing with a true analogue or analog (not to be anal) display, component cables will do the job perfectly. This will be especially true of your DVD source if it is outputing 480i/p. If it is an upconverting DVD player... one that mathmatically changes the signal to digital at an upsampling rate via an HDMI or DVI connection, I still advise to run it with component cables to eliminate a secondary and unnecessary digital to analog conversion (DAC). Keeping the datastream simple seems to introduce less artifacts (errors). Also make sure that all of the settings in the user controls of the DVD player are off. Noise reduction or "mosquito noise" etc. Use the displays controls if necessary when watching SD television.

Proper setting of the B/W levels cannot be overstressed. Follow the directions of the test disk implicitly.

Your ability to control the color controls is limited without accurate grayscale calibration so adjust the blue color bars with the provided filter, then eyeball the saturation and hue controls until you get skin tones to look natural during a daylight scene.

All that being said, if you really want it to show everything it can, check with the Imaging Science Foundation at www.imagingscience.com for a calibration professional near you.

In the meantime, have fun with your new display!

Good viewing,

Doug k

Mike,

Would you happen to know the best picture settings for the Panasonic PT-43LC14?

BTW, "analog" is the better accepted format in the U.S. "analogue" is from British English, but still accepted in U.S. :yippee:

The most I have read in this thread has been very good information and advice. However, almost everyone's idea of what represents good picture quality is usually different.
For example, I have used Avian (?) and Video Essentials for many years to periodically try to callibrate my TVs to the best picture for each source. In most instances, I have not been pleased with the results and have gone back to visually making my own picture adjustments.
Some of the presets work well, like the movie setting for DVD's. But I find that most mfgs. set the Picture (contrast), Sharpness and color way too high. I like a softer picture, with the picture setting at midpoint, the brightness slightly higher and the color and sharpness below midpoint.
If you experiment with the callibration DVD and visually, you will find the picture settings that work best for you.

LOL. You can use the AVIA tune up dvd to make the bookmark settings, and take your own eyes to tweek it. Most people get use to a bad picture, so when they see a tv with proper set up, they automatically think its bad. Ill get back to yous about the setup settings. There is two, the standard setting and the movie setting.
The standard setting is set and ment for high def signals.
