Hi Def sports broadcasts on hi def channels are extremely sharp and detailed but other than that, viewed from any distance, the picture is lacking in detail -- like sitting in the third row at the cinema. Even
TV studio broadcasts are fuzzy, although all lettering, such as display text or subtitles is razor sharp. Is that the state of this industry? When I saw this unit on display in the store a few years ago, it showed stunning detail, but I suppose in-store set ups are special. I use video component connections and the source is a cable provider with a "high def" box. Is there any way to improve this disappointing performance? I don't think it is the unit but the source: garbage in - garbage out. One other exception is material from public television -- most of that material is tack sharp. Other so called Hi Def channels are fuzzy -- bad enough that my friends wonder what is wrong when they see it. Any ideas? Please advise.

It looks like you are saying standard definition pictures do not cover the screen like HD pictures do. Standard def is formatted 4:3 and high def is 16:9. They are not the same so your high def screen is made to display the not as tall but wider high def picture. In order to fill the screen with the taller and not as wide 4:3 aspect ratio std def picture you must tell the TV to stretch the picture or otherwise fill the screen.The TV will have controls you can exercise for this purpose and you can set it up to always show std def in a particular manner. The alternative, if you want the standard Def picture to look true to form, is to view standard def in Letter Box form. It's appearance will then include black panels on the sides of the picture. So the problem is not with the TV but in accepting older format pictures playing on newer format displays (TVs.)
Remember you have to have a High-Def signal source to actually view High-Definition video. This means local broadcast TV in HD or digital cable TV with HD service and a HD channel or satellite or a Bluray Disc.
This is caused by your QAM decoder on hi def Sharp sets. You need to rescan for channels, turn off your TV then turn it back on to set to save the channels.The problem lies in the Tuner board and some Hi-Def signals can change frequency slightly due to improperly shielded cables etc. Verify that all of your cables, especially the Cable TV wire are firmly seated on your set. An improperly grounded cable television wire can wreak all kinds of havoc on reception.
Your flat panel TV is probably factory set to receive ATSC signals (Hi-def DIGITAL TV), whereas
Ghana may not have converted from analog TV (NTSC) yet.
Digital TV's cannot receive analog signals. I'm just guessing about whether or not Ghana supports
Hi-Def broadcasts - you'll have to check with (any) TV channel in Ghana. The Analog-to-digital
conversion is an expensive one at the broadcast end, and may not have happened yet in Ghana.
The US conversion took place by FCC mandate June 12, 2009.
There are available $65 (USD) digital-to-analog converters, but what you may need is an
analog-to-digital converter, which doesn't exist. Your Flat-panel TV amy have to wait until Ghana
begins broadcasting a Hi-Def TV channel.
For a HD antenna, a regular old rabbit ear-type antenna will do.
I have a BENQ PE8700 also. Charter Cable just replaced my Hi Def Cable Box and now I only get the non hi-def channels. I get the sound on the Hi-Def channels only. My projector is hooked up with the DVI Cable. Did you ever find out why you were not getting HI DEF?
When you are changing channels you are using the tuner of the sat reeiver. the tv does not know you are changing a channel . It is just receiving a constant signal from the SAT receiver. I would suspect a problem with the receiver. Try another one first .
I've seen this problem after changing high-def channels sometimes. I found if you switch to a low-def channel, then back, it stops jumping. This causes it to re-sync. An annoyance. Too bad there aren't any firmware updates to be found.
Deacon J, You will need a digital converter box OR high definition tuner for the transition. What's the difference? A converter box will only output a standard definition signal, either on channel 3 or by composite or S video cables. A high definition tuner will allow you to watch the new digital broadcasts in hi-def, assuming they are transmitted in hi definition. The converter boxes are the cheaper option and you can get a coupon from the government for a $40 rebate on the box, but I would opt for the hi-def tuner fo the better picture quality.CNET has a good write up on the transition here: http://www.cnet.com/1990-7874_1-5108580-3.html I did some looking and about the cheapest hi-def tuner I could find was $150, which is 3 times what a converter box would cost. I would expect the cost to fall on the tuners over time. Perhaps a converter box may be a good solution until the prices fall, if they do. The problem is that not many companies are making the tuners, as most TV's already have a hi-def tuner built in, so there isn't a big market for the add-on tuners. I hope this answers your questions.
in order to get the full HD experience you should be using HDMI cables. if you're using the white/red/yellow cables then your HD channels will not broadcast in full HD and you'll be stuck with the annoying black things around your screen
