Your Sharp Aquos 40D78UN is a 1080P HD display, and will provide razor sharp, vibrant images if provided with an HD signal.

HD signals (those that are 720P, 1080i and 1080P) are only available from the following sources:

1) Local "off air" (antenna) HD broadcasters (providing HD content) delivered via the coaxial antenna terminals.

2) An HD source such as a stand alone Blu Ray (BD) Disk player, PlayStation 3 optical (BD) disk, HD service provided by DirecTV, Disk Network, Local CATV provider or other satellite service delievered to the TV via any of the (3) HDMI jacks or (2) Component RCA jacks (RGB). Satellite and CATV providers offer both SD and HD service. You must have HD service to watch programs in the higher quality HD format.

3) Computer signals delivered via the PC (VGA 15 pin) jack - such as movies or video in HD or Netflix HD.

It is important to note that any signal source (regardless if 720 or even 1080) that is delivered to the TV via either of the (2) "A/V" RCA jacks, will be limited to SD or 480i resolutions.

An HD picture is only possible when the source is HD, it is brought to the display over HD cables to HD capable jacks on the TV and, the display is capable of at least 720P. If any one of these variables is missing or substituted, the picture quality will be reduced significantly.

CNet has a helpful review and discussed HD signals. it is only a couple pages in length and may help you understand even better. I hope this helps and good luck! Please rate my reply - thank you.

Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

The picture quality is very poor. Picture is fuzzy.


Did you turn the ring on the camera itself? The camera does not automaticaly adjusts itself. You must turn the lens to focus manualy.

If nothing works and you just bought this camera, call microsoft and they will help you more.

When i zoom in the picture is all fuzzy


digital zoom is different from optical zoom. when using digital zoom, you have to keep the camera very, very, very still. may even have to use a tripod.

Picture quality terrible on Microsoft LifeCam VX-1000 Webcam


You should be able to adjust the focus by adjusting the lens.The little housing where the lens is should be able spin a bit. If you gently spin it a bit, it should change the sharpness of the image on the screen.

I hope this help you.

Cable is plugged in but picture is fuzzy, what do I do?


You have a rip saw that has a cable with a fuzzy picture?

If this is a cable TV question, two things come to mind ... TV is out of adjustment or you have some ground wires touching your center conductor on your RG-59 or RG-6 cable (or just came to mind - you have split the signal so many times there is no signal).

You can use a cable tester to test the quality of the cable ... you can cut off the ends and replace them. More likely than not, unless you have pro tools and ends (F fittings) you will not get much improvement from this. If you are guilty of multiple splitters in the line, reduce the number of splitters.

If this is a saw question, I dont understand your trouble.

Picture not clear


Get a HDMI lead it makes HD tv look how it is suppose to look HIGH DEFINITION. You'd think it naturally is suppose to look great but these people are rip offs you need that additional peice which should make it spot on for you. Try stores such as maplin & currys. Get the gold plated HDMI lead better quality

Good luck

Just purchased tv and the quality of the picture is still fuzzy tried to mess around with the resolution but it still isnt very sharp at all


Hi,
The TVs produce picture using entirely different methods. Usually the colors and especially level of black color are better on plasma, LCD will have some trouble various shades of gray and black especially shading on peoples faces etc.. This is not a defect in the LCD just a limitation in current technology.

Hi Thomas,
Have you tried adjusting your resolution? To maximize the quality of video/picture that your webcam can capture, Turn the resolution into 1.3megapixel. Adjusting the resolution is by clicking the arrow above the Video Option.

Lg 37in the picture cquality in hd is sometimes fuzzy


There is quite a lot you can do. Go to menu, picture settings and select user 1. From here you can adjust everything from colour to contrast to warmth to sharpness. The best thing to do is to swith to XD manual adjustment and make sure the mpeg noise reduction is set to max. This removes artifacts and gives a better picture. Oddly, connecting via SCART rather than HDMI will give a more watchable picture if the HD broadcast is't at a very high bit-rate. I hope that helps :o)
