JPEG storage reduced


Don't confuse bytes with pixels. A pixel is point of color. A byte is a unit of computer storage. A picture with 10 million pixels may or may not require 10 million bytes of storage.

As an exercise, take a picture outside your window, properly exposed and focused. Now put your camera into manual mode, select a fast shutter speed (1/1000 will do), put the lens cap on, and take a picture. Compare the two file sizes. The first file should have a lot of detail in it and will be quite a bit larger. The second file should be all black. The two pictures will have the same number of pixels, but require different amounts of storage.

In the worst case, each pixel will require three bytes to specify its color. JPEG files will be compressed so it's not quite this bad. At the other extreme, it doesn't take many bytes to say "3872x2592 pixels, every one of them absolutely black."

Intermittent problem of sound breaking up and picture pixelating


usually a problem with your cable box. Try plugging a different tv into the cable box and see if it does the same thing. if so, call cable provider. If not, more than likely is a problem with your main board. but very unlikely.

All picture taken found with 1 white dot at the location


The problem you are encountering is called a "dead pixel". Every ccd has several dead pixel, so it is quite normal. But I agree that it can be annoying.
The solution is to map the bad pixel and to substract them afterhands.
Go to http://chdk.wikia.com/wiki/Main_Page and download the latest firmware for you camera here http://mighty-hoernsche.de/.
It is a supplement to your camera that will open hundreds of possibilities, like making time-lapse recordings, doing your own scripts, shooting RAW,...as well as a feature for removing bad pixels.
All you have to do is to read! Yeah, I know, there are lots of things written :p
More specifically, here is the "how to use badpixel removal" explanation.

Need to Increase the DPI on my Fuji S5000


It does not work like this.

You can select the quality of the pictures (pixels) with the "F" key.
What you are talking about is "dots per inch", and that has to do with your printer.................,
where you can increase the dpi. 300dpi is not high quality at all !

Picture sixe reduced and picture breaks up with converter box


You can change the way the channels can be displayed/viewed by a video setting, consult manual. When pic breaks into pixels and sound goes it's usually a reception problem so you'll have to adjust the antenna facing a direction that makes that channel come in clearly. It helps to experiment with positions and antennas.

Need settings because of rubbish picture


There is no right or wrong setting for the TV, but I find the following give about the best results:

  • Contrast - 65 maximum
  • Sharpness - 2 maximum
If these are set any higher, the picture becomes very grainy, particularly around defined shapes.

  • Contrast + - OFF
  • NR - ON (If applicable)
These settings will need to be changed for each of the following:
HDMI 1& 2
  • EXT 1, 2 & 3
  • Analogue tuner
  • Digital tuner
The problem you describe, is usually with a satellite or cable box.

Unfortunately, there's nothing much you can do about the dead pixels, but the settings may make them less obvious.

My HDTV breaks into pixels. How can I prevent this?


From what I heard, comcast is sending is compressed video signal. I also witnessed this on a xbr5 at someones home. Its not your tv from what I've heard its your provider trying to keep up with demand. I hope that helped.

Bright pixels?


Just a thought: doesn't the C-4040Z have pixel mapping for just this eventuality? Run that, and the stuck pixel cluster should disappear. Of course, whether you should * have* to use the facility straight away is a matter of personal opinion..., but at least there is something you can do about it. Use caution though, as presumably you can't get the stuck pixels back afterwards to use as your reason for returning the camera.
