I have a 42 inch LG 20 (1080)and I just had Dish Network hook up the HD box. I am not receiving any full screen pictures in the HD. The TV is set at 16:9 ratio and the HD box is at HD normal. I have black bars on both the top and bottom of the screen and the picture looks stretched. Any ideas?

I currently have a Sony SXRD set, but i want to purchase a new Panasonic 1080p plasma set, but im worried about “Burn in” bcuz i play video games alot. Is “burn in” still an issue with plasma sets
Also is the “Response time” of the new panny plasmas higher than the 2.5 respone time of the Sony SXRD sets?

I have not seen classic “burn in ” on the new Panasonics , but I supposed it is possible if you leave the game frozen on a score for days at maximum contrast (+30 picture) . I have had reports of short term image retention caused by each pixel holding a charge after changing the image, seen as a ghost image of theescore This will automatically fade by simply turning off the display.

According to all the gamers I speak with, when it comes to action games , plasmas picture kill LCD. I simply recommend a low contrast mode like movie and cineqm and lowering the contrast control to where you stil have a bright enough image for playin g, this should be less than half of the picture controls maximum setting

i installed a pioneer elite 61″ plasma running component through a elite 35tx receiver and then to the panel. I am getting blue rectangluar sparkles in the right third of the screen from top to bottom of the screen. Can you tell me what might be the issue here? is it noise induced by the receiver as it passes through or could it be an improperly terminated cable, which was mini-rgb under carpet running about 20 ft…but that seems unlikely since its in the right 1/3 only and not ascross the entire panel. look forward to hearing your opinion.
regards

Insuffiecent data for an answer. Could either be the display, the receiver, source or the cable. You need to test by running another cable direct from the source to the same input on the display and see if the problem is eliminated. If yes, then its is either the cable or the surround receiver and you need to repeat with the new cable and the surround receiver in the signal path . The process of elimination is how to determine where a problem like this resides.

My pdp has a ‘buzz’ sound that emits from rear of unit through the perforated back cover. Is this electric sounding ‘buzz’ normal? Not audible from a couple perhaps three/four feet away with no volume being used. I know my pc power supply/fans make noise but should my pdp tv? Unit is new fanless Vizio P50hdtva10 with less than 25 hrs on it. Thank you for your time.

I purchased the TH-50PX600U 50-Inch HDTV you recommended, for the Super bowl of course. In part because it was recommended by the HD GURU and I think I got it cheap.. I’ve watched 2 movies, Flags of our Fathers and The Departed, neither of these filled the entire screen, even after changing the aspect ratio, when the movies ended you could see the top and bottom lines on the blank screen. How long does it take, for the lines,from any source movies or TV,to actually burn in?
If UR not watching HD set the cable receiver to whatever the feed is???
Do the grey bars burn in too??
One suggestion:
A search feature on your site would be great.
Lots of INFO!!! Thanks!!!!

If you turned down the contrast and took the set out of Vivid mode as recommended, what you are seeing is image retention not burn-in and it usually fades away in under 60 minutes. It’s nothing to worry about.

I purchased the Vizio ph50hdtv plasma tv. I have about 2 hours on the unit. Yes…2 hrs. I have noticed in this short time that images of the dvd’s screen saver/wallpaper and the units own osd menu are visible ever so slightly when powering the set to on. It appears as a ghost like image or what I guess burn-in would look like. Is this normal and should I be over concerned. BTW…I have set in custom mode with contrast to less than 50/half as well as brightness, etc. Setup is correct but ghost-like images are worrying me. Thanks for your time.

Plasmas tend to retain a slight charge within their pixels, causing a ghost image like you describe from static images or the on-screen menu. It only appears for a few minutes and usually with scenes that are really dark or black. This image retention is not permenent or long lasting like uneven phosphor wear known as burn-in. Don’t worry.

is the phillips 32″ lcd falat panel hdtv a good one? the model i am interested in is 32pf7421d/37
thank you

The HD Guru can’t comment on models he has not evaluated. This is one of them. However, Philips makes their own LCD panels in a factory jointly owned by LG Electronics.

Ok I bought the Vizio 50″ plasma and Panasonic dvd recorder.

Now I need a sound system.

Do I want to get something digital?

I have an old 5 speaker pro-logic entertainment center I hooked up to the TV. But I almost think the sound from the TV speakers sounds better. Just only comes from one direction.

The Vizio has a digital out port as does my DVD player.

What happens when I’m watch SD television. If the signal isn’t broadcast digitally will the sound system still work if its only hooked up to the digital out port?

Thx Guru

hello i recently bought a 57″ mitsubishi hd1080 and my question is did i buy a good tv and what and how can give me a top of the line picture as this is my first big screen and i just want to know if i have any thing special to do i would really appreciate your help

—————————————————————————————————

A 2006 (currrent) Mitsubishi DLP will be in my top picks for my upcoming Miscrodisplay article, they make some great HDTVs.

Make sure you put the TV in Low color tempature and “natural” mode for the most accurate image.

You need to feed it the best signal possible for the best HD Picture. If you have Verizon Fios TV in your area, I recommend it . Over-the-air (OTA) HD will also give you all the bits the local broadcaster is providing,. Next it gets dicey as cable systems vary from excellent to poor around the country. The two satellite companies (Directv and Dish) have been lowering the bit rate on HD and I would choose one of them if you can’t get OTA or cable (or you cable provider offers poor or no HD)

If you are a movie watcher the latest HD DVD players from Toshiba and the latest Blu-ray from Sony , Panasonic and Pioneer make excellent HD pictures.

I have been sitting on the sidelines for some time delaying my HDTV purchase having never really been satisfied with the image quality I have seen. More importantly, I have been waiting for Sony to introduce their grating light valve technology in a consumer level product. Do you have any insight as to when this might occur? What do you think of GLV display technology and the resolution possibility it promises?

cheers, Rodney

————————————————————————————————

Sony has been mum about the GLV for 2-3 years, my guess, its on the back burner. Sony has been developing its SXRD technology for home and commerical cinema instesd . The key part of the GLV technology is a laser light source and at least one company, Mitsubishi says they will release a laser driven DLP rear projector before the end of 2007
